The Importance of Digital Communications During Infectious Diseases Oubreaks

As we all know, the H1NI pandemic has been raging on for close too 10 ten days now. Curiously, “Fear & The Flu: The New Age of Pandemics” is the title this week’s cover story in Newsweek magazine. From an informational standpoint point, “this may be too little, too late”—as the old saying goes. While the Internet has been around for over twenty years now, government agencies, most notably the US Food and Drug Administration (FDA) and the Centers for Disease Control (CDC) continue to rely almost exclusively on old media to communicate with the American public during infectious disease outbreaks. Apparently, the administrators who run these government agencies haven’t been listening closely enough to President Obama’s assertion that “we live in the digital age.”

Communications between the public and government health officials is vital when trying to manage and control infectious disease outbreaks. “Every single government agency as well as companies and non-profits need to be digitally literate and competent in a time of pandemic” asserts Eye on FDA blogger Mark Senak. For their performances in recent infectious disease outbreaks, Mark gives CDC an “A” for effort—although there is substantial room for improvement. FDA on the other hand didn’t fair as well. “The FDA is not nearly as sophisticated in terms of digital. Their only Twitter account is for food recalls.  And their YouTube channels are all confusing and unorganized. They have a long way to go.”

The Internet was originally designed as a digital tool to transmit and move large amounts of information from one place to another. That said, it is also a powerful communication vehicle that can be used to broadcast valuable, scientifically-accurate information during infectious disease outbreaks by leveraging social media tools like Twitter, Facebook and instant messaging. To that end, it’s time for public health agencies to recognize the power of digital media and craft communication plans that can be implemented in the next infectious disease outbreak.

Until next time...

A New Year and Another Salmonella Food Poisoning Outbreak

Salmonella enteriditis, an organism dear to my heart (luckily not my posterior small intestine) is a common cause of food poisoning. As some of you may know, I did my PhD thesis work on Salmonella gastroenteritis (aka food poisoning) and I like to think that I am something of an expert on the topic. 

Typically, Salmonella food poisoning outbreaks are localized and rarely reach epidemic proportions. However, there have recently been two major nationwide Salmonella outbreaks in the US —one in 2007 and now in early 2009.

The current outbreak has afflicted 388 people in 42 states and may be caused by the same strain (Saint Paul) that was responsible for the 2007 outbreak. Ultimately, the 2007 outbreak was linked to contaminated tomatoes. The jury is still out on the cause of the most recent outbreak. Needless to say, CDC scientists are scurrying to quickly identify the source of the current outbreak because it took the agency over 5 months to conclusively identify the culprit in the 2007 epidemic. Not surprisingly, many grocery stores and restaurants suffered financially because of the outbreak.

Many of you may be wondering why Salmonella food poisoning is becoming such a problem in the US. I don’t believe that the strains responsible for the most recent outbreaks are more virulent than the ones that have traditionally caused more localized outbreaks. Instead, the reliance of food manufacturers and grocery store chains on one or two major food distributors (rather than multiple suppliers) is likely responsible for the severity and breadth of these nationwide outbreaks. This suggests that regulatory agencies ought to more closely scrutinize the microbiological quality of the operations of the major distributors. I believe that those efforts would greatly reduce the likelihood of future major outbreaks of food poisoning.

Until next time.

Twenty-Five Percent of American Teenage Girls Were Vaccinated with Gardasil in 2007

The Centers for Disease Control and Prevention said about 25% of teenage girls received at least one dose of Merck & Co.'s Gardasil vaccine in 2007, providing the first national estimate of usage of the company’s controversial anti- HPV (cervical cancer) vaccine.

A 25% usage rate for a a new vaccine during its first year on the market is outstanding. That said, Merck’s Gardasil is the only approved anti-HPV vaccine in the US. Approval of GlaxoSmithKline’s competing product, Cervarix, by FDA has been delayed for so-called “regulatory issues.” Also, Merck has been heavily promoting Gardasil use via well-crafted DTC ads and a variety of clever promotional campaigns aimed at adolescent girls and their mothers.

Despite all the negative press and Merck’s questionable marketing practices, Gardasil appears to be doing very well—something that Merck desperately needs.

Until next time…

HPV and Homeland Security

 On the surface, you wouldn’t think that the Human Papilloma Virus (HPV, the causative agent of venereal warts and cervical cancer) and US Homeland Security have much in common. However, they have more in common than you think as reported in yesterday's Pharmalot blog.

According to a report by the TheStreet.com , Homeland Security’s US Citizenship and Immigration Services (USCIS) is the first government agency to mandate that all female immigrants’ ages 11 to 26 years old be vaccinated against HPV. Because Gardasil is the only cervical cancer (HPV) vaccine that is approved for use in the US it will the vaccine used for the mandatory immunizations. Surprisingly, there is no HPV vaccination requirement for US visa holders or American citizens.

Since the policy was begun, an estimated 233,000 females aged 11 to 26 who entered the US as prospective citizens paid a combined $52 million or so for the vaccinations according to the Street.com article. Curiously, the USCIS is requiring only a single injection for females who receive the vaccine—the Gardasil label indicates that three injections are required for full anti-HPV effectiveness.

As you may recall, more than 20 states rejected plans backed by Merck to make Gardasil vaccination mandatory. Merck abandoned its campaign after parents and medical experts expressed concern about safety and effectiveness. While Gardasil vaccination is optional for American citizens, there is apparently no opt-out provision for females who simply want to immigrate to the US. The confusion may like lie in a document issued by the US State Department called form DS-3025, or “vaccination documentation worksheet which says vaccination against “Human Papillomavirus is required for US immigrant visa applicants.” Here is the form.

John Abramson, the former chairman of the CDC’s Advisory Committee for Immunization Practices when the HPV requirement began in April 2007, and an opponent of mandatory vaccination said “This is not a disease that is communicable like SARS or pandemic flu or even measles.” “I am stunned. It was not the intention of the policy to mandate vaccination of immigrants,”

Ironically, Merck which has been pushing as hard as it can to promote Gardasil use isn’t aware of the Homeland Security policy, according to a Merck spokeswoman. It just goes to show how effective unregulated pharmaceutical lobbying can be!!!

Despite a Few Warts, CDC and FDA Say Gardasil is Safe and Effective

A post at the Pharmalot blog said that the US FDA and the Centers for Disease Control issued a statement today indicating, that after reviewing side effect reports, Merck’s anti-HPV (cervical cancer) vaccine Gardasil is safe and effective, and its benefits continue to outweigh its risks.

According to the statement, the joint agency review determined that 94 percent of  all side effects reported after Gardasil vaccination were not serious. The most commonly reported adverse events fainting, pain at the injection site, headache, nausea and fever. Fainting is common after injections and vaccinations, especially in adolescents, the agencies noted.

Although there have been 20 reported deaths following vaccination, there was no common pattern or tend that would suggest they were caused by the vaccine itself. The statement went on to say that in cases where autopsy, death certificate and medical records were available, the cause of death was explained by factors other than the vaccine.

The statement was likely issued in response to highly publicized and widely circulated adverse events reports issued by the ultraconservative Judicial Watch which is morally opposed to HPV vaccination. It is extremely unfortunate that a small but vocal group of conservative Christians are willing to risk the health of their daughters because they are morally opposed to premarital sex and birth control.

Salmonella in the News Again

This may be one of the more notable years for Salmonella food poisoning. First, there was a modest outbreak in the eating clubs at Princeton University and now a larger outbreak in Texas and New Mexico. This is the first time that I can recall in my almost 30 years as a card-carrying food microbiologist that there has been this many highly-publicized cases of Salmonella food poisoning in one year. Although I don’t wish Salmonella gastroenteritis on anybody, it is kind of rewarding that an organism that led to my PhD is making headlines once again. Typically, Salmonella outbreaks are not noteworthy and rarely receive much notice— usually taking a backseat to potentially life-threatening outbreaks of enteropathogenic Escherichia coli.

Like the Princeton outbreak, the exact source of the Salmonella infection is unclear. That said, public health and CDC officials are leaning towards large, raw tomatoes. In 2006, the Food and Drug Administration discovered that consumption of tomatoes in restaurants had caused a salmonella outbreak that affected 21 states. , “until the source of the outbreak is identified federal and local health officials in both states have recommended that infants, the elderly and anyone with an impaired immune system avoid eating Roma and red round tomatoes that are not grown at home or sold attached to the vine.” So far, 40 confirmed cases, with patients ranging in age from 3 to 82, have been reported in New Mexico and Texas since April. To date, 17 people have been hospitalized, but no deaths have been reported.

Molecular analyses indicated that all of the cases in New Mexico and Texas were caused by the same strain, a relatively rare serovar called Saint Paul (6th most common serovar infecting humans). Federal health officials at the Centers for Disease Control in Atlanta, GA fear that this may be the beginning of a large national outbreak of Salmonella gastroenteritis. This is because about 30 cases caused by the Saint Paul strain, have also been reported this year in Arizona, Colorado, Idaho, Illinois, Indiana, Kansas and Utah. Like the New Jersey, Texas and New Mexico outbreaks, the cause of those other outbreaks is under investigation.

Salmonella gastroenteritis generally last between four and seven days, and most people are able to recover without medical (antibiotic) treatment. But, it can sometimes lead to death in immunocompromised adults or young children. Symptoms include headache, nausea, abdominal pain, diarrhea and sometimes vomiting.  Although textbook descriptions of the pathogenesis of Salmonella gastroenteritis generally portray it as a mild illness, I can tell you that people I know (lab mates of mine) who came down with the disease (gee, how did that happen?) suggest otherwise!

I suspect that fecally-contaminated water may be source of the infection. But, then again, it has been almost 30 years since I thought about Salmonella gastroenteritis. That said, I don’t think that you ever forget the essence or minutiae of your thesis work!

For those of you who are interested, the electron micrograph of Salmonella typhimurium shown with this post is from my PhD dissertation. As I recall, the electron micrograph was taken in 1980 and the bacterium shown in the micrograph was grown for 48 hours on nutrient agar . Althought I would like to take credit for the shot (nice pose eh?),  it was taken by Phil Hegge in the Department of Bacteriology at the University of Wisconsin-Madison, my alma mater. if you look closely you may be able to see fimbriae along with the flagella.

Until next time
