What You Can Do to Stay Healthy

Get vaccinated. Vaccination is the best protection we have against flu. Seasonal flu vaccine is available now and initial doses of 2009 H1N1 flu vaccine also are available, with additional doses available later this year.
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. If soap and water are not available, use an alcohol-based hand rub.
- Avoid touching your eyes, nose and 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.
