Swine Flu Update: Reasons Not to Panic... Yet!!!

The potential swine flu pandemic has been on everyone's minds, as the number of cases has been increasing daily.

However, while there is potential for the sporadic number of cases to turn into a worldwide pandemic (global outbreak), there is little reason for Americans to panic... just yet.

First, earlier news reports may be misleading with regards to the actual number of cases of swine flu in Mexico. According to the World Health Organization (WHO), the ~800 cases are actually pneumonia, of which only 18 cases have been confirmed as swine flu. In fact, while the high number of flu-like cases may appear alarming, one news story indicated that the Mexican government did not find the numbers of cases to be unusual, compared with previous years. In a press conference with the WHO, Director-General Dr. Margaret Chan discussed a need to answer critical questions, "for example, how many of the 800 plus cases of severe pneumonia requiring hospitalization are indeed caused by this new virus, or other causes."

Secondly, no deaths from swine flu have occurred in the U.S. As of today, the Centers for Disease Control (CDC) has reported that there are now 20 confirmed human cases of swine flu i n the U.S. (8 in New York, 7 in California, 2 in Kansas, 2 in Texas, and 1 in Ohio), none of which have resulted in death. Canada has also reported 6 cases, all of which have been mild.

Third, this strain of influenza is susceptible to antiviral drugs oseltamivir (Tamiflu) and zanamivir (Relenza), which are both FDA-approved drugs that reduce the duration of disease.

Fourth, the WHO has not restricted travel or trade because of swine flu. They and the CDC are increasing surveillance over the situation, having declared the current event as a "Public Health Emergency of International Concern". But at the same time, they have stated that "it is too premature at this stage to make those announcements [of border closures and travel advisories] without, first and foremost having a better analysis." In fact, the WHO regularly follows global influenza outbreaks and has an established pandemic preparedness action plan in the event of a real swine flu pandemic.

Finally, while the current flu vaccine does not protect against the current outbreak strain of swine flu, development and production of a new effective vaccine is achievable, although it could take months to produce enough to meet global demands.

Why is the disease wreaking more havoc in Mexico? Well, keep in mind that the vast majority of cases have not been confirmed as swine flu. In addition, parts of Mexico have poor nutrition levels, poor air quality, and poor access to health care, according to one report.

In short, stay on the lookout for symptoms of flu in yourself and your loved ones, and contact your health care provider if you suspect the flu. Continue to practice good hygiene (washing hands frequently, covering your mouth when you cough, etc.). And keep reading the news. But don't panic... yet!!!
