There was an earlier thread on this I couldn't find, but for those who are interested, here is what the CDC says...
Swine Flu UpdateIn mid-March 2009, an outbreak of human infections with a new strain of swine flu was reported in Mexico. In late March and early April 2009, human infections with swine flu were reported in southern California and Texas. Human infections in other states have subsequently occurred. The Centers for Disease Control and Prevention (CDC) is conducting an investigation into the spread of swine flu, and current information about conditions in the United States can be found here:
http://www.cdc.gov/swineflu/investigation.htm General Information Swine flu is a type of respiratory disease commonly found in pigs, caused by type A influenza viruses. The disease normally does not infect people, but swine flu can and has caused sporadic human illness, usually among people with direct exposure to pigs. Some cases of swine flu resulting from human-to-human transmission have been documented. While some people who work around pigs may have developed immunity to the swine flu virus, it is likely that most people are susceptible to infection. If the swine flu virus develops efficient person-to-person transmission, the disease will be able to spread among human populations.
Swine flu infection in humans can vary in severity from mild to severe, with pneumonia and respiratory illness. Symptoms in humans are similar to those seen among persons infected with typical seasonal influenza - fever, coughs, body aches, headaches, fatigue, and runny or stuffy nose. While most cases reported in the United States over the past few decades have not resulted in deaths, some fatalities have occurred.
Persons infected with swine flu may be contagious as long as they exhibit symptoms, and up to 7 days after onset of their illness. As with seasonal influenza, you can reduce your chances of being infected with swine flu, or infecting others, by taking the following precautions:
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 hand cleaners are also effective.
Try to avoid close contact with sick people.
If you get sick with influenza, 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 this way.
Travel Advice and Recommendations The CDC publishes Travel Notices.
