Human cases of swine influenza A (H1N1) virus infection have been identified in the United States. Human cases of swine influenza A (H1N1) virus infection also have been identified internationally. The current U.S. case count is provided below.

An investigation and response effort surrounding the outbreak of swine flu is ongoing.

CDC is working very closely with officials in states where human cases of swine influenza A (H1N1) have been identified, as well as with health officials in Mexico, Canada and the World Health Organization. This includes deploying staff domestically and internationally to provide guidance and technical support.

CDC activated its Emergency Operations Center to coordinate the agency's response to this emerging health threat and yesterday the Secretary of the Department Homeland Security, Janet Napolitano, announced a public health emergency in the United States. This will allow funds to be released to support the public health response. CDC's goals during this public health emergency are to reduce transmission and illness severity, and provide information to assist health care providers, public health officials and the public in addressing the challenges posed by this newly identified influenza virus. To this end, CDC has issued a number of interim guidance documents in the past 24 hours. In addition, CDC's Division of the Strategic National Stockpile (SNS) is releasing one-quarter of its antiviral drugs, personal protective equipment, and respiratory protection devices to help states respond to the outbreak. Laboratory testing has found the swine influenza A (H1N1) virus susceptible to the prescription antiviral drugs oseltamivir and zanamivir. This is a rapidly evolving situation and CDC will provide updated guidance and new information as it becomes available.

There are everyday actions people can take to stay healthy.

Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
Avoid touching your eyes, nose or mouth. Germs spread that way.

Try to avoid close contact with sick people.

Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
If you get sick, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
