Professor Vincent Racaniello, a BioCrowd co-founder, blogger and host of the increasingly popular This Week in Virology (TWIV) podcast series made an anguished plea in a recent post on his Virology Blog to help promote American science literacy. “If you are writing a book, article, toy label, or anything having to do with viruses, and you are not sure of the science, feel free to contact me for advice. I will check the facts for free, because my goal is for everyone to get the science right” said Professor Racaniello.

Vincent expressed his sentiments in a post entitled “Even Toy Makers Should Get it Right” which takes a company to task (Giant Microbes) for manufacturing  “an influenza virus toy” (yes you heard it correctly) and mistakenly presented incorrect information about the influenza virus in the toy’s promotional materials and on its label (an image of the incorrect materials is displayed in the upper left hand corner of this post) . 

While only a toy, I agree with Vincent that it is imperative that all relevant facts about an infectious agent ought to be correct to insure that lay people, many of whom will never read another thing about viruses in their lives, get scientifically correct information. That is the essence of science literacy!

I have known Vincent for over 35 years and I think he is one of the brightest and most unassuming world class scientists that I know (yeah I know a few). One of the things I like most about Vincent is that he is a stickler for detail and (for as long as I have known him), never draws a scientific conclusion unless it there is incontrovertible proof that it is the correct conclusion.  While I routinely rail against self-focused and uncaring academics, Vincent is exactly the opposite. His unwavering commitment to teaching and increasing the public awareness of viruses, and science in general, is second to none. And when he says, please feel free to contact him for help he truly means it and will do everything possible to help you find what you need. Having said that (yes, I know you hate that phrase Vincent; btw so does Larry David), if any of you aspiring young scientists out there need a role model, I highly recommend that you keep Vincent in mind. And, if you need virology help or want to chat with him you can find him on twitter @profvrr or of course, at the BioCrowd!

Until next time....

Good Luck and Good Job Hunting!!!!!!!!

Flu season is upon us and, not surprisingly, there is no dearth of information available to the public about the seasonal and H1N1 flu vaccines. Mostly there are stories about the lack of availability of the vaccines, underreporting of deaths associated from H1N1 infections and perhaps, most importantly concerns about flu vaccine safety. Despite attempts by the CDC and a few dedicated virologists like BioCrowd co-founder Vincent Racaniello, flu vaccine manufacturing is an enigma to the lay public.

While I am a card-carrying microbiologist, my knowledge of the manufacturing of flu vaccine is admittedly lacking. With this in mind, I came across an outstanding tutorial about flu vaccine manufacturing published by the College of Agriculture at the University of Wisconsin-Madison (my alma mater). The UW tutorial is easy to understand and will shed light on and help to demystify flu vaccine production for lay people (and a few scientists like me).

Yesterday, after giving a talk on social media to a great NYC-based PR firm called Ricochet,I decided to take an uptown trip to visit Professor Vincent Racaniello at Columbia University Medical School to talk about the new applications that we plan to introduce to BioCrowd.

When I arrived at Professor Racaniello’s office, which has an outstanding view of the Hudson River and George Washington Bridge, he was in the middle of taping this week’s This Week in Virology (TWiV) podcast with co-hosts Dick Despommier and Alan Dove. Much to my surprise, Vincent invited me to join the conversation although I am a bacteriologist not a virologist. The podcast was devoted mainly to answering questions that listeners had submitted to the show. One listener alerted us to a post at Newsweek Online entitled “Fight Flu and Falsehoods” while we didn’t agree with the author’s assertion that “that hand washing doesn’t affect the transmissibility of influenza”—it does reduce infections rates of other viruses, bacteria and parasites, so it is a good idea to continue to wash your hands—accompanying the article was an outstanding online quiz that assesses how much you really know about influenza and other viruses. 

I think it would be fun for BioJobBlog readers to take the quiz, report scores and then tabulate the results.

To take the quiz, click here and to report your score click here!  I will tabulate the results and share them in a later post if enough BioJobBlog readers and their friends take!

Until next time

Good Luck and More Luck On the Quiz!!!

There was an interesting article in the New York Times this past week entitled“Do Women Need Such Big Flu Shot.” The gist of the article was that we would have more doses of influenza 2009 H1N1 vaccine if we accounted for the biological differences between the immune responses in men and women follow influenza vaccination (the article cites a study that contends that less vaccine is need to elicit an protective response in women as compared with men.

I was going to write a post about the article but I got distracted and thought I would revisit it when I had more time. Much to my surprise, Vincent Racaniello, a Bio-Crowd founder, virologist extraordinaire and host of the popular TWiV podcast series, had already “scooped” me. Professor Racaniello graciously allowed me to crib his entire post and let BioJobBlog readers decide for themselves whether or not there are real differences in the male and female immune responses to influenza vaccines or the results obtained by the scientists who conducted the study may be explain by strain to strain variation among influenza A isolates? Read Professor Racaniello’s post below and let me know what YOU think!

Do women need the same amount of influenza vaccine as men?

by Vincent Racaniello

“Do Women Need Such Big Flu Shots?” suggests that we would have more doses of influenza 2009 H1N1 vaccine if we accounted for the biological differences between men and women. The idea is that women generate a stronger antibody response than men, and therefore require less vaccine. Does this idea have scientific support?

The opinion is based in part on a study carried out in 2004-05, in which adults were immunized with full (15 micrograms) or half-doses of trivalent inactivated influenza vaccine. This vaccine, made by Aventis Pasteur, contains influenza H3N2, H1N1, and B strains. Serum samples obtained before immunization and 21 days later were assayed for antibody response to each strain of influenza by hemagglutination-inhibtion. I’ve taken the data on geometric mean serum HI titers according to age, sex, and dose and plotted them on a graph:

Based on the results the authors conclude that “Significantly higher geometric mean titer responses in women were identified for all ages, regardless of dose or influenza strain. Half-dose vaccination may be an effective strategy for healthy adults younger than 50 years in the setting of an influenza vaccine shortage.” But are these immune responses protective?

HI titers of 1:40 or more (which would be reported as 40 or higher in the graph) are believed to indicate levels of antibody that would protect against infection with influenza virus. By this criteria, the full and half dose of vaccine would provide protection agains the influenza H3N2 and B viruses in both men and women. The results confirm that females respond more strongly to the same dose of vaccine than men. But look at the results with the H1N1 strain – in all subjects, no matter the dose of vaccine or gender, the antibody response would not be sufficient to protect against infection. Furthermore, the response is only slightly better than in women.

In interpret these observations to mean that the antibody response to inactivated influenza virus vaccine is not universally more robust in women compared with men – it appears to depend on the virus strain. Clearly clinical studies are required to address this question. Even after spending millions of dollars to decide whether to give women less influenza vaccine, a new strain of influenza virus might come along that induces no better antibody response in women than in men.

My conclusion is that it would not be possible to determine conclusively that women could receive half the amount of inactivated influenza virus vaccine as men. I would rather spend money on developing new ways to produce as much influenza vaccine as needed as quickly as possible – such as by making virus-like particles in plants.

Engler RJ, Nelson MR, Klote MM, VanRaden MJ, Huang CY, Cox NJ, Klimov A, Keitel WA, Nichol KL, Carr WW, Treanor JJ, & Walter Reed Health Care System Influenza Vaccine Consortium (2008). Half- vs full-dose trivalent inactivated influenza vaccine (2004-2005): age, dose, and sex effects on immune responses. Archives of internal medicine, 168 (22), 2405-14 PMID: 19064822

 Until next time...

I regularly watch Real Time with Bill Maher and generally agree with many of the political views and ideas that he espouses. In fact, I am a fan! However, his rant two weeks ago about the H1N1 vaccines, and vaccination in general, showed me that while politically astute and incisive he has absolutely no understanding about science and modern medicine (see video below). Making matters worst, his guest, former conservative senator Bill Frist, a surgeon by training, was ill prepared to correct and refute some of Maher’s outrageous assertions regarding the differences between the two currently available H1N1 vaccines and the basic principles of vaccinology.

Maher is quick to tell people that they are stupid when they don’t agree with his ideas or political views. And, he rightfully criticized George W. Bush for routinely making decisions about important issues based on “his gut feelings” rather than facts. Ironically, this is exactly what Bill Maher does when he talks to his guests about medicine and food. Maher, who may be a vegetarian and is clearly anti-traditional medicine,  is quick to point out that Westernized medicine and food production is profit driven and consequently, any information or advice offered by the US government is little more than a ploy to keep people sick and fat. In other words, don’t trust anything that the government tells you if you believe otherwise or you heard it from a celebrity. 

I suspect that science wasn’t Bill’s “cup of tea” (he frequently calls the tea baggers who don’t trust anything that the Obama administration tells them idiots and morons) and may have never taken anything he learned about science seriously. If he had, he might have learned how vaccines work and realized that modern vaccines (the first vaccines were produced in the 1780s) protect over 95% of people who receive them from devastating childhood diseases and even cervical cancer. Instead, he cites bogus and scientifically refuted claims about vaccine safety including mercury poisoning, links to autism and the miniscule possibility of developing Guerin-Barr Syndrome (which was first observed in large number of patients following vaccination with the 1976 Swine Flu vaccine). Shockingly, despite incontrovertible evidence to the contrary he continues to spew misinformation and flat-out wrong claims about vaccines. Ironically, his wrong-headed vaccine tirades are remarkably similar to those of the Birthers —people who refuse to believe that President Obama is an American despite incontrovertible evidence to the contrary—and racists who contend that Obama is a Muslim—two groups that he is quick to bash and dismiss as crazies and morons. In other words, Maher believes that he is right even though he is clearly misinformed or wrong!

Originally, I was going to write this post after Maher’s “Real Time” tirade about vaccines almost two weeks ago on Real Time. However, I relented but couldn’t help myself after reading an article in today’s Scientist Times about a pregnant woman who lost her second child after she contracted the flu. As many of you may know, pregnant women are very susceptible to influenza which could have serous consequences for the mother and baby. This is an exchange the woman had with a physical therapist with whom she was working to regain muscle control after being hospitalized (and near death) for almost 4 months:

“Have you ever read the labels?” she (the physical therapist asked). “They’re so full of toxins.”

Asked if she realized that a shot, had it existed in June, might have saved her client and her baby, she frowned and went back to her clipboard.

Are you kidding me—full of toxins? This is exactly what Maher was trying to imply during his anti-vaccine rant on Real Time. Unfortunately, millions of people listen to him and celebrities like Oprah, Dr. Phil and Maher and many believe (and blindly follow) their recommendations and advice. While this may not be a problem when talking about hair color, books to read or weight loss it is extremely troubling and dangerous when it comes to scientific and medical advice. The problem is that a vast majority of Americans are scientifically illiterate and are either incapable or unwilling to analyze and evaluate scientific or medical information on their own. This forces many people to rely on the Internet, government agencies and sometimes healthcare professionals to do their medical and scientific thinking for them. And when things go wrong, or not as advertised, they are quick to accuse the government or the healthcare industry of withholding information and engaging in nefarious conspiracies. This is exacerbated by the fact that science and medical reporting in the US is grossly inadequate, often wrong and frequently designed to be as sensationalistic as possible. Is it any wonder why the American public is often confused and misinformed about science and medicine?

My scientific training has taught me to analyze and evaluate all available data before I draw any conclusions on a topic. And, as an infectious disease expert I believe that childhood vaccines are unequivocally safe and effective. To that end, they have substantially reduced the morbidity and mortality associated with mumps, measles, diphtheria, whooping cough, pneumonia, tetanus, almost eradicated polio and eliminated smallpox from the planet. There is no doubt that there are risks associated with vaccination and that a small number of those vaccinated may experience some side effects or serious adverse events. But, the small risks associated with modern vaccines don’t outweigh the benefits and positive effects on billions of people who may have lost their lives if they hadn’t been developed in the first place. I wonder whether or not an anti-vaccine movement would exist today if smallpox and polio were still causing as much death, disfigurement and paralysis as they had prior to development of the smallpox and polio vaccines in the mid 20^th century.

In closing, as an American, I believe that everybody is entitled to their opinions and the right to freely express them. However, I implore Bill Maher get the FACTS right before summarily bashing a topic and making recommendations to the millions of people who watch Real Time and believe what he says. Otherwise, he is no smarter or better than the ignorant, close-minded, right wingers who he regularly trashes on his show.

Until next time...

The Belgian chemical manufacturer Solvay announced today that it had agreed to sell its pharmaceutical business unit to Abbott Pharmaceuticals for $6.6 billion. By purchasing Solvay, Abbott gains access to emerging markets in Eastern Europe and Asia along with new therapeutic areas, including hormone therapies and vaccines. Solvay's flu vaccine Influvac will give Abbott an entrant in the burgeoning vaccines market, which is currently dominated by European pharmaceutical giants like GlaxoSmithKline and Novartis.

Abbott already holds U.S. marketing rights for Solvay's Trilipix and TriCor, drugs which raise "good" HDL cholesterol while reducing triglycerides and "bad" LDL cholesterol.

Solvay's other top-selling drugs include the Parkinson's disease treatment Duodopa and hormone therapy drugs AndroGel and Duphaston. It is not clear whether or not the Solvay purchase will affect ongoing pharmaceutical operations or staffing decision in the US. However, I suspect that there will be management changes and layoffs in Europe.

In other news, Johnson & Johnson bought an 18 percent stake in Dutch biotechnology company Crucell NV, which is trying to develop a universal flu vaccine, while competitor Merck acquired the rights to sell Australia-based CSL Ltd.'s Afluria flu vaccine in the U.S.

The Solvay deal is the latest in a string of mergers and acquisitions, as cash-rich pharmaceutical companies race to acquire new products amid looming patent expiry on blockbuster drugs. Earlier this year Swiss drugmaker Roche acquired Genentech following similar deals uniting Pfizer Inc. and Wyeth, and Merck & Co. Inc. with Schering-Plough.

Expect more M&A activity in the life sciences sector before year’s end.

Until next time...

As an iPhone user, I am constantly amazed at the applications that are developed for it. I recently downloaded a flashlight app that converts my iPhone into a flash light in case of a power outage or finding myself in the dark like I did two summers ago at Moosehead Lake in Maine. Just when I thought iphone apps couldn’t get cooler, I learned about a new app called “Outbreaks By Me.” It was developed by researchers at Children's Hospital Boston in collaboration with the MIT Media Lab, enables users to track and report outbreaks of infectious diseases, such as H1N1 (swine flu), on the ground in real time. The application can be downloaded from iTunes.

According to a press release “the application builds upon the mission and proven capability of HealthMap, an online resource that collects, filters, maps and disseminates information about emerging infectious diseases, and provides a new, contextualized view of a user's specific location – pinpointing outbreaks that have been reported in the vicinity of the user and offering the opportunity to search for additional outbreak information by location or disease.” An additional feature of Outbreaks Near Me is the ability to set alerts that will notify users via text or by e-mail when new outbreaks are reported in their proximity, or if users enter a new area of activity. It also offers an option for users to submit an outbreak report which will allow people in cities and countries around the world to interact with the HealthMap team and participate in the public health surveillance process.

What will iPhone app developers think of next— an app for swine flu vaccination?   Now that would be way cool!

Until next time....

Good Luck and Good Swine Flu Hunting!!!!!!!

Since the beginning of the pandemic last spring, BioCrowd founder and virologist extraordinaire Vincent Racaniello has been vigilantly writing at his at his Virology Blog about HIN1 pathogenesis, epidemiology, immune responses and vaccines.  When not blogging about HIN1, Vincent also writes about other viral diseases and does a weekly virology podcast called This Week in Virology (TWIV).

In a very short time, Professor Racaniello has amassed a huge collection of original articles that could be compiled into a virology textbook with a title like “Everything you ever wanted to know about H1N1.” And, not surprisingly, his Herculean efforts have not gone unnoticed: today his Virology Blog was recognized and listed as a legitimate source of H1N1 information by the New York Times. 

For those of you who haven’t been overwhelmed by the unrelenting swine flu media frenzy and are seeking sound information about the H1N1 epidemic, I highly recommend that you check out Vincent’s blog. Also, you can talk with Vincent at BioCrowd when he is not too busy blogging, podcasting or conducting laboratory research.

Until next time...

Professor Vincent Racaniello, a BioCrowd co-founder and virologist who studies the pathogenesis of polio and influenza viruses commented that there will likely be two influenza vaccines offered this fall: a trivalent vaccine consisting of seasonal H3N2 and H1N1 strains and an influenza B strain; and a monovalent one consisting of the 2009 pandemic H1N1 strain.

He posited an interesting question to BioCrowd members earlier today: "Will you be receiving a flu vaccine this fall, and if so, which one?"

To weigh in on the topic and find out which vaccines makes sense for you, check out Professor Racaniello’s influenza vaccine survey and discussion at BioCrowd!

The Public Library of Science (PLOS) announced that it has launched a new website called PLOS Currents that is intended to serve as a vehicle for the rapid publication of scientific research and new ideas and themes. Not surprisingly, the first theme for PLOS Currents is influenza. On his Virology blog, Vincent Racaniello, a BioCrowd cofounder and prominent virologist, discusses why PLOS Currents is important and timely for scientist actively engaged in influenza research and vaccine development.  

The opening of PLoS Currents: Influenza was announced by Harold Varmus, Chairman and Co-Founder of PLoS. He wrote about the reasons for starting this website at The Official Google Blog:

The key goal of PLoS Currents is to accelerate scientific discovery by allowing researchers to share their latest findings and ideas immediately with the world’s scientific and medical communities. Google Knol’s features for community interaction, comment and discussion will enable commentary and conversations to develop around these findings. Given that the contributions to PLoS Currents are not peer-reviewed in detail, however, the results and conclusions must be regarded as preliminary. In time, it is therefore likely that PLoS Currents contributors will submit their work for publication in a formal journal, and the PLoS Journals will welcome these submissions.

Contributions that will be welcome at PLoS Currents: Influenza include research into influenza virology, genetics, immunity, structural biology, genomics, epidemiology, modeling, evolution, policy and control. The manuscripts will not be subject to peer-review, but unsuitable submissions will be screened out by a board of expert moderators. This policy will enable rapid publication of research.

The path to publishing original scientific research is often long and tortuous.  A manuscript describing the findings is prepared and submitted to a scientific journal (such as Nature, Cell, Journal of Virology). The manuscript is assigned to two or three expert reviewers, generally scientists involved in the same area of research. If their reviews are favorable, the paper is published. Usually additional experiments are called for, which may require additional time to complete. Many months to a year may pass before the paper is published, although some manuscripts (e.g. those on 2009 pandemic influenza) may be expedited. The point is that PLoS Currents: Influenza will allow everyone – including non-scientists – to read about research soon after the authors have prepared the paper.

PLoS Currents: Influenza is a terrific idea, and I welcome this venture with great enthusiasm. I hope that PLoS Currents will grow to include other areas of science. But Varmus warns:

Given that the contributions to PLoS Currents are not peer-reviewed in detail, however, the results and conclusions must be regarded as preliminary. In time, it is therefore likely that PLoS Currents contributors will submit their work for publication in a formal journal, and the PLoS Journals will welcome these submissions.

During peer review of submitted manuscripts, new experiments may be suggested that change some of the conclusions of the research. Hence, the papers that appear in PLoS Currents: Influenza may be different from final versions that are published elsewhere.

I wonder how other scientific journals will react to submissions of manuscripts that have appeared in PLoS Currents. Many journals do not accept manuscripts that have already appeared elsewhere. For example, the instructions to authors for the Journal of Virology state:

By submission of a manuscript to the journal, the authors guarantee that they have the authority to publish the work and that the manuscript, or one with substantially the same content, was not published previously, is not being considered or published elsewhere, and was not rejected on scientific grounds by another ASM journal.

It’s time for scientific journals to change this policy, and allow for preliminary publication at sites such as PLoS Currents.

Rapid and open-access publication will drive research forward and help inform and educate the public about science.

The appearance of the Swine Flu aka H1N1 last spring not only created a worldwide panic, it demonstrated to Albert Osterhaus, head of virology at the Erasmus Medical Center in the Netherlands how uninformed the lay public was about viral outbreaks, epidemiology and public health. This prompted Dr. Osterhaus and his colleagues to create a free, online video game called the “The Great Flu” which challenges players to control a new viral pandemic.

As the virus has spread worldwide, countries have tried different methods to slow it down and pharmaceutical companies are now racing to produce a swine flu vaccine (sound familiar?). To fight the emerging outbreak, players use public health measures including setting up surveillance systems, stockpiling antivirals and vaccines, and closing schools and airports. Players also have a limited budget and are warned that "your actions to control the virus cost money, so keep an eye on it." In other words, while the goal is to control the pandemic, there may not be sufficient funds and resources to accomplish those goals!

A running tally of the numbers of people infected and those who have died are displayed above the budget. Newspaper stories about the deadly virus and the global response to it — like riots breaking out worldwide — pop up to help players monitor the outbreak and plan their next moves. Messages from governments mirror the difficulties faced by international agencies like WHO that are responsible for containing worldwide epidemics. For example, when players set up costly surveillance systems, sometimes participating governments will send a message "we will comply with your directions...but we must inform you that the political support for this action is low in this region. Therefore, the effectiveness of the system to control the outbreak may differ from your expectations."

The goal of the game is make the lay public aware of the difficulties that public health officials encounter during pandemics and the tight rope they sometimes must walk to insure that the virus is contained and doesn’t continue to spread. To test your skill level at controlling pandemics, you can choose different viruses (which range from easy to difficult to manage) at the beginning of the game.

I think “The Great Flu” is a great way to educate the public about infectious diseases and epidemiology and have fun at the same time. If you are interested in more sinister online swine flu games check this out.  Who said learning science has to be tedious and dull?

Until next time...

On several occasions while driving in upstate New York, I noticed an exit sign on the NY State Thruway for Coxsackie, NY. And, not surprisingly, I began to wonder whether or not the Coxsackie virus was named after this obscure upstate NY town.

I first learned about coxsackie viruses as a graduate student while taking a medical virology course at the University of Wisconsin taught by the late noble laureate Howard Temin. However, despite a thirty year friendship with Vincent Racaniello, a BioCrowd co-founder and virologist extraordinaire, I never asked him about the origin of the coxsackie virus name. Much to my surprise, he had recently taken a trip to upstate NY and noticed the Coxsackie NY exit sign while driving on the thruway. This prompted him to blog about the coxsackie virus isolation, its pathogenic properties and of course, the origin of its name!

Coxsackie NY and the virus named after it 

by Vincent Racaniello,PhD

Recently while driving north on the New York State Thruway I passed the exit for the town of Coxsackie, NY (population 8,884). I grabbed my camera and photographed the exit sign, and reminded myself to write about the virus named after this small town.

In the summer of 1947 there were several small outbreaks of poliomyelitis in upstate New York. Gilbert Dalldorf, the director of the Wadsworth Laboratory in Albany, NY, and his associate Grace M. Sickles investigated this outbreak. In particular they sought polioviruses that could replicate in mice. This search was motivated by the fact that research on poliovirus required the use of monkeys which were extremely expensive. Dalldorf had attended the Fourth International Congress for Microbiology in 1947 where he heard that very young mice – suckling mice – could readily be infected with Theiler’s virus.

Dalldorf and Sickles made fecal suspensions from two children suspected of having poliomyelitis, and inoculated these into adult and suckling mice. Only the suckling mice (1 – 7 days old) developed paralysis; animals more than one week old were resistant to infection. The damage responsible for limb paralysis was widespread lesions in skeletal muscles, not in the central nervous system as occurs with poliovirus. Further study revealed that the viruses could be distinguished serologically from poliovirus.

Not only had Dalldorf and Sickles identified the first members of a very large group of human viruses, but they also introduced and popularized a new and inexpensive animal into the virology laboratory – the suckling mouse. In 1949 Dalldorf suggested that the new viruses be called Coxsackie viruses, because the first recognized human cases were residents of that New York village. This unique name is of native North American origin.

Over ten years later the importance of this work was recognized by Dr. Max Finland of Boston City Hospital:

The isolation by Dalldorf and Sickles of viruses which produced paralysis with destructive lesions of muscle in sucking mice and hamsters, from the stools of two children with signs of paralytic poliomyelitis was an achievement that may rank in importance with Landsteiner and Popper’s production of human poliomyelitis in monkeys.

In subsequent years many different Coxsackie viruses were isolated that cause a variety of clinical syndromes. Today at least 30 serotypes of Coxsackie viruses are classified in the enterovirus genus of the Picornaviridae. The viruses are classified into groups A or B depending upon the pathological effect in suckling mice.

Not every locale is pleased to have a virus named after it. In May 1993, an outbreak of an unexplained pulmonary illness occurred in the southwestern United States, in an area shared by Arizona, New Mexico, Colorado and Utah called “The Four Corners.” Muerto Canyon was proposed as the name for the etiologic agent of the disease, because the virus was first isolated from a rodent near the canyon. However after residents objected, the name Sin nombre virus was given to the agent of hantavirus pulmonary syndrome.

Dalldorf G, & Sickles GM (1948). An Unidentified, Filtrable Agent Isolated From the Feces of Children With Paralysis. Science (New York, N.Y.), 108 (2794), 61-62 PMID: 17777513

A quick perusal of the media coverage of the swine flu outbreak of 2009 would lead many to conclude that this outbreak has the potential to rival or surpass the 1918 flu pandemic—widely regarded as the worst influenza outbreak in history. While the emergence of a new H1N1 swine flu variant is significant note worthy— and has possible public health implications— the unrelenting, often scientifically-inaccurate media coverage did little to quell the fear and anxiety of many Americans.  Once again, the media—rather than physicians, public health officials and influenza experts—“got out in front of the story” and managed to create enough panic, fear and anxiety, the likes of which haven't been seen since the 2003 SARS pandemic. It wasn't until last Friday, when the Wall Street Journal published an interview with Dr. Peter Palese—a leading scientific expert on influenza A infections— did a clearer picture emerge about the severity and public health implications of the current swine flu pandemic.

According to Dr. Palese, there are several reasons why people and public health officials ought to be optimistic about the current pandemic:

• In 1976 there was a an outbreak of an H1N1 swine virus in Fort Dix, New Jersey, which showed human to human transmission but did not go on to become a highly virulent pandemic strain
• The presently circulating swine virus is most likely not more virulent than the other seasonal strains we have experienced over the last several years
• The current swine virus lacks an important molecular signature (the protein PB1-F2) which was present in the 1918 virus and in the highly lethal H5N1 chicken viruses.  If this virulence marker is necessary for an influenza virus to become highly pathogenic in humans or in chickens, then the current swine virus doesn’t have what it takes to become a major killer
• Since people have been exposed to H1N1 viruses over many decades, we likely have some cross-reactive immunity against the swine H1N1 virus. While it may not be sufficient to prevent becoming ill, it may very well dampen the impact of the virus on mortality.  I would postulate that by virtue of this “herd immunity” even a 1918-like H1N1 virus could never have the horrific effect it had in the past.  The most likely outcome is that the current swine virus will become another (fourth) strain of regular seasonal influenza

The landscape of vaccines and anti-influenza drugs has dramatically improved over what it was just a few years ago. Based on what we know of the structure and sequence of the swine virus, these FDA-approved drugs and FDA-licensed vaccines (modified to include the swine strain) would be highly effective against this new virus.  Also, present technologies as well as manufacturing capacities will allow us to make sufficient quantities of a swine virus vaccine for the winter 2009-10 influenza season in the US.

In other words, there is reason for concern but no need to panic beyond typical public health precautions that are taken during “normal” influenza outbreaks.

Dr. Vincent Racaniello, a viral disease expert who writes the Virology Blog, reported that as of Monday there have been laboratory confirmed cases of H1N1 infections in 30 US states with a total of 226 cases and one death in Texas. Globally, 20 countries had reported 985 cases of infection. The highest numbers are in Mexico, with 590 cases and 25 deaths. While there have been 26 deaths to date, the severity of the infection appears to be waning and person-to-person transmission appears to be low.

Unfortunately, there has been some fallout from the news media’s oft times “over the top” coverage of the pandemic. Many US hospital emergency rooms (most notably in Texas and California) have been overwhelmed and overburdened by visits from people who think they may have swine flu. Also, while some schools and daycare center closures were warranted, others may not have been. Finally, and perhaps most important, it is becoming increasingly apparent that the lay public's understanding of infectious agents and the outbreaks that they cause is grossly deficient and must be improved. 

We live in a world where viral pandemics, food poisoning outbreaks and infections caused by multiple-antibiotic resistant bacteria are becoming commonplace. While vaccines, antivirals and antibiotics can afford some protection against many viral and bacterial disease, the best way to fight infectious diseases is to understand what causes them, how they are spread and what public health measures can be implemented to prevent or control their transmission. Until the world becomes better educated about infectious diseases, we will continue to be overly-dependent on the news media during future outbreaks and epidemics.

Until next time....

Do you lie awake a night overwhelmed by the possibility of another infectious disease outbreak? Well, if you want to get a good night’s sleep, I highly recommend that you take a look at a brief history of American epidemics that was published in this past Sunday’s New York Times. According to the article, history shows that the number of American epidemics has been relatively small. In fact, the author suggests that there were only nine major epidemics in the US since 1892. 

While there were several major outbreaks in the early to mid 1900s (Spanish flu, 1918; smallpox, 1947 and polio, 1952), the US has been relatively unscathed in recent years—with the possible exception of the HIV/AIDS epidemic and possibly the herpes and HPV epidemics. This is because of America’s outstanding infectious diseases surveillance networks, its comprehensive vaccination programs and modern medical and hospital infrastructures.

However, no matter how vigilant we are, there is no way to prevent infectious disease outbreaks unless the pathogens that cause the diseases are eradicated from the planet as was the case for the smallpox virus. That said, the best way to manage infectious disease epidemics is to be prepared for all contingencies.  In my opinion, the recent swine flu outbreak—this was its second appearance, the first taking place in 1976—was a practice run. And I think the world did “pretty, pretty good” as Larry David, my former NYC softball teammate and co-creator of Seinfeld would say!

Until next time...

Vincent Racaniello, an intrepid virologist and BioCrowd co-founder, has been keeping folks up to date on the swine flu outbreak on his blog. Today, Vincent wrote: “There are now 257 laboratory confirmed cases, with 7 deaths, in 11 countries. In the US there are 109 cases  in 11 states. There are many more suspected cases; together the statistics indicate widespread dissemination of the new H1N1 influenza virus. I no longer doubt that this is the next pandemic strain. WHO will probably soon raise the level of influenza pandemic alert from phase 5 to phase 6. Important questions include whether spread will continue in the northern hemisphere through the summer, or stop very soon, as is the case with most influenza virus outbreaks. Unfortunately the southern hemisphere seems in for an extended flu season. Will antivirals be useful in reducing morbidity and mortality? Will the virus returns to the north in a more virulent form in the fall? Can a vaccine be prepared in time?”

 For answers to these questions and others, please visit the Virology Blog or join BioCrowd to chat with Vincent. Check his virology blog for the most up-to-date swine flu information.

 Until next time...

By now everybody has heard that there is a Swine Flu epidemic that started in Mexico and may morph into a worldwide pandemic.  The media's coverage has been mind numbing and overwhelming.  For those of you who want the real skinny on the outbreak, I recommend that you read a post on the Virology Blog run by BioCrowd founder and virologist Vincent Racaniello.

Vincent did his PhD work on flu in Peter Palese's lab, one of the world's leading influenza experts.  In addition to his blog post, Vincent along with Dick Despommier and Alan Dove created a also created a podcast on swine flu last Friday as the epidemic began to unfold. Check it and other virology podcasts out on This Week in Virology (TWiV).

Until next time....

Good Luck and Good Reading/Listening

No matter what you may think of Google, you gotta love the brilliance and innovative moxy of the guys who run that company. In today’s New York Times, there was a story about a new web tool called Google Flu Trends. This tool is being evaluated as a new early warning system for fast-spreading flu outbreaks in the US.

Tests of Google Flu Trends, suggest that it may be able to detect regional outbreaks of the flu a week to 10 days before they are reported by the Centers for Disease Control and Prevention (CDC). It works by tracking and quantifying number of Americans who enter search phrases like “flu symptoms” into Google and other search engines. By analyzing these searches as they come in, Google Flu Trends creates graphs and maps of the country that show where the flu is spreading.  For example, in early February the CDC reported that the flu cases had recently spiked in the Mid-Atlantic States. But Google says its search data showed a spike in queries about flu symptoms two weeks before the CDC report was released.

According to public health experts “The CDC reports are slower because they rely on data collected and compiled from thousands of health care providers, labs and other sources. The Google data could help accelerate the response of doctors, hospitals and public health officials to a nasty flu season, reducing the spread of the disease and, potentially, saving lives.” Researchers have long contended that information published on the Web amounts to a form of “collective intelligence” that can be used to spot trends and make predictions.

Google Flu Trends appears to be the first public project that uses the powerful database of a search engine to track a disease. This could be the beginning of a new trend in epidemiology. Google hopes to publish the results of its study in Nature.

Until next time…
