Swine Flu as Cause of Pneumonia in Mexico Not Fully Understood
The CDC and WHO is assisting Mexican health officials to determine if the severe respiratory illnesses seen in Mexico are the result of swine flu. As of yesterday, the link between swine flu and severe pneumonia cases in Mexico is not fully understood.
The most recent CDC report reads, “7 specimens from Mexico at CDC have tested positive for the same strain of swine influenza A (H1N1) as identified in U.S. cases. However, no clear data are available to assess the link between the increased disease reports in Mexico and the confirmation of swine influenza in a small number of specimens.”
The latest CDC report, issued April 25, 2009, 3:00 EST. identified eight confirmed laboratory cases of swine flu in the United States – four in San Diego County, two in Imperial County, California, and two in Guadalupe County, Texas.
Recommendations for frequent hand washing continue to be the best way to prevent swine flu spread. The CDC cautions anyone with fever, body aches, sore throat or other flu-like symptoms to seek medical attention for appropriate testing. The anti-viral drug Tamiflu is effective for limiting swine flu symptoms.
The World Health Organization convened Saturday, April 25 for a special meeting. The committee concluded that swine flu constitutes a “public health emergency of international concern”, but that more information is needed before a swine flu pandemic is declared.
The CDC still says there is no need to stop travel to areas affected with swine flu, which include San Diego or Imperial counties, California, or Guadalupe County, Texas. You can find guidelines for travel at http://wwwn.cdc.gov/travel/contentSwineFluUS.aspx
