Swine Flu and You
What is Swine Influenza?
Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. Swine flu viruses cause high levels of illness and low death rates in pigs. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks in humans. The classical swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930.
How Do You Catch It?
Although people do not normally get the swine flu, the virus is contagious and humans can be infected. The virus is spread from person to person by coughing and sneezing. Humans are typically contagious anywhere from one day before the start of the illness to 7 days after onset. Note: Swine flu CANNOT be contracted from eating pork and pork products.
What are the symptoms of swine flu in humans?
According to the Centers for Disease Control, the symptoms of swine flu in people are very similar to seasonal influenza and generally include fever, fatigue, lack of appetite and coughing, although some people also develop a runny nose, sore throat, vomiting or diarrhea,
Are there human infections with swine flu in the U.S.?
In late March and early April 2009, cases of human infection with swine influenza A (H1N1) viruses were first reported in Southern California and near San Antonio, Texas. Other U.S. states have reported cases of swine flu infection in humans and cases have been reported internationally as well. An updated case count of confirmed swine flu infections in the United States is kept at http://www.cdc.gov/swineflu/investigation.htm. CDC and local and state health agencies are working together to investigate this situation.
How can I avoid catching it?
- Frequent hand washing. Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also helpful.
- Avoid contact with those who are ill.
- Cover your nose and mouth with a tissue (or your elbow) when you cough or sneeze. Throw the tissue in the trash after you use it.
- Do not touch your eyes, nose or mouth. Germs spread that way.
