Swine Influenza in the United States
This information is current as Monday, April 27, 2009 at 10:19

Updated: April 26, 2009

Revised April 26 to reflect updated guidance on antiviral use in travelers.

Current Situation

As of 9 am April 26 2009,  20 human cases of swine influenza A (H1N1) virus infection have been identified in California, Texas, New York City, Kansas and Ohio.  This strain of influenza virus is unique because it is a combination of genes from swine, bird, and human influenza viruses. Infected individuals report flu-like symptoms of fever, aches and pains, sore throats, coughing and trouble breathing. Some people have also reported diarrhea and vomiting.  These cases may be linked to an outbreak of influenza-like-illness in Mexico.

At this time only two of the 20 cases in the US have been hospitalized and all have recovered. However, CDC and state public and animal health authorities are still in the early stages of the investigations.

Further updates to the US investigation and any related travel recommendations will be posted on www.cdc.gov/travel when available.
