• On April 26, 2009, Janet Napolitano, the Secretary of the Department of Homeland Security declared a public health emergency due to the increasing number of people being diagnosed with the swine flu. As of April 27, 2009, there had been 40 confirmed cases of swine flu infection in the U.S., but as of that date, there had been no swine flu related deaths in the nation. Like most other strains of influenza, the elderly, very young, and those with preexisting medical conditions that have weakened their immune systems are at higher risk of becoming seriously ill after contracting the swine flu.

• The CDC provides up to date reports on any epidemic, including the swine flu outbreak of spring 2009. As of April 27, there had been:

1. 7 cases in California
2. 2 cases in Kansas
3. 28 cases in New York City
4. 1 case in Ohio
5. 2 cases in Texas

• Visit the CDC website or pay attention to local, national and international news reports to ensure you are aware of any recent developments and remain informed about where and how the swine flu is believed to be spreading.

• The swine flu is believed to spread mainly from person to person via airborne germs expelled when an infected person coughs or sneezes. To help prevent from being infected:

1. Wash your hands often with warm water and antibacterial soap
2. Avoid touching foreign surfaces
3. Avoid touching your face, especially the areas around your eyes, nose and mouth
4. Always cover your mouth when you cough or sneeze and wash your hands immediately after doing so
5. If you are unable to wash your hands regularly, carry an alcohol-based hand wash or hand sanitizer with you and use it regularly
6. Avoid areas or people that may be contaminated
7. If you need to visit a contaminated area or feel you are at high risk for contracting the disease, consider wearing a face mask

• Although the World Health Organization had not recommended any border closures or travel limitations as of April 27, 2009, those who felt ill were advised to delay traveling internationally whenever possible. In addition, people who developed flu-like symptoms after traveling to foreign countries were advised to see a doctor.

• The swine flu spreads similarly to other flu viruses. Therefore, the same things you would do to prevent contracting other airborne viruses, such as washing your hands regularly and avoiding contact with contaminated people or areas, may also help you avoid swine flu infection. If you feel as though you may be infected with the swine flu, visit a health care professional immediately and minimize your contact with other people.
