International Human Cases of Swine Flu Infection

*Case is resident of KY but currently hospitalized in GA.

The ongoing outbreak of novel influenza A (H1N1) continues to expand in the United States. CDC expects that more cases, more hospitalizations and more deaths from this outbreak will occur over the coming days and weeks.

CDC continues to take aggressive action to respond to the expanding outbreak. CDC’s response goals are to reduce spread and illness severity, and provide information to help health care providers, public health officials and the public address the challenges posed by this emergency.

CDC is issuing updated interim guidance daily in response to the rapidly evolving situation.

School Guidance

This includes updated interim guidance for schools and childcare facilities on preventing the spread of novel influenza A (H1N1) virus. At this time, CDC recommends the primary means to reduce spread of influenza in schools focus on early identification of ill students and staff, staying home when sick, and good cough etiquette and frequent hand washing. Decisions about school closure should be at the discretion of local authorities based on local considerations.

Increased Testing

CDC has developed a PCR diagnostic test kit to detect this novel H1N1 virus and has now distributed test kits to all states in the U.S. and Puerto Rico. The test kits are being shipped internationally as well. This will allow states and other countries to test for this new virus. This increase in testing capacity is likely to result in an increase in the number of reported confirmed cases in this country, which should provide a more accurate picture of the burden of disease in the United States.

More on the Situation

What You Can Do to Stay Healthy

  • Stay informed. This website will be updated regularly as information becomes available.
  • Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
  • Take everyday actions 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.
    • Stay home if you get sick. CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
  • Follow public health advice regarding school closures, avoiding crowds and other social distancing measures.
  • Find healthy ways to deal with stress and anxiety.
  • Call 1-800-CDC-INFO for more information.

NOTE: This is a rapidly evolving situation and current guidance and other web content may contain variations in how this new H1N1 virus of swine origin is referred to. Over the coming days and weeks, these inconsistencies will be addressed, but in the interests of meeting the agency's response goals, all guidance will remain posted and new guidance will continue to be issued.
