Swine Influenza (Flu)
Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza that regularly cause outbreaks of influenza among pigs. Swine flu viruses do not normally infect humans, however, human infections with swine flu do occur, and cases of human-to-human spread of swine flu viruses has been documented. General information about swine flu can be found on the General Information about Swine Flu page.
From December 2005 through February 2009, a total of 12 cases of human infection with swine influenza have been reported from 10 states in the U.S. Beginning in March 2009, a total of 5 laboratory confirmed human cases of swine influenza virus infection have been identified in California. An investigation into the human swine flu cases in California is ongoing. More information is available on the Human Swine Flu Investigation page.

Residents of California and Texas
CDC has identified human cases of swine influenza A (H1N1) virus infection in people in these areas. CDC is working with local and state health agencies to investigate these cases. We have determined that this virus is contagious and is spreading from human to human. However, at this time, we have not determined how easily the virus spreads between people. As with any infectious disease, we are recommending precautionary measures for people residing in these areas.
- 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.
- Try to avoid close contact with sick 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.
- Avoid touching your eyes, nose or mouth. Germs spread that way.
There is no vaccine available at this time, so it is important for people living in these areas to take steps to prevent spreading the virus to others. If people are ill, they should attempt to stay at home and limit contact with others. Healthy residents living in these areas should take everyday preventive actions.
People who live in these areas who develop an illness with fever and respiratory symptoms, such as cough and runny nose, and possibly other symptoms, such as body aches, nausea, or vomiting or diarrhea, should contact their health care provider. Their health care provider will determine whether influenza testing is needed.
Clinicians should consider the possibility of swine influenza virus infections in patients presenting with febrile respiratory illness who:
- Live in San Diego County or Imperial County, California or San Antonio, Texas or
- Have traveled to San Diego and/or Imperial County, California or San Antonio, Texas or
- Have been in contact with ill persons from these areas in the 7 days prior to their illness onset.
If swine flu is suspected, clinicians should obtain a respiratory swab for swine influenza testing and place it in a refrigerator (not a freezer). Once collected, the clinician should contact their state or local health department to facilitate transport and timely diagnosis at a state public health laboratory.
State Public Health Laboratories
Laboratories should send all unsubtypable influenza A specimens as soon as possible to the Viral Surveillance and Diagnostic Branch of the CDC’s Influenza Division for further diagnostic testing.
Public Health /Animal Health Officials
Officials should conduct thorough case and contact investigations to determine the source of the swine influenza virus, extent of community illness and the need for timely control measures.
