CDC recommendations for travel to and within the United States:
Before your trip:
Monitor the outbreak situation Check updates at http://www.cdc.gov.
Prepare for your trip Be sure you are up-to-date with all your routine vaccinations, including seasonal influenza vaccine if available. Identify the health-care resources in the area(s) you will be visiting.
During your trip:
Monitor the local situation Pay attention to announcements from the local government. Follow local public health guidelines, including any movement restrictions and prevention recommendations.
Practice healthy habits to help stop the spread of novel H1N1 flu.
Wash your hands often with soap and water. This removes germs from your skin and helps prevent diseases from spreading.
Use waterless alcohol-based hand gels (containing at least 60 percent alcohol) when soap is not available and hands are not visibly dirty.
Cover your mouth and nose with a tissue when you cough or sneeze and put your used tissue in a wastebasket.
If you don’t have a tissue, cough or sneeze into your upper sleeve not your hands.
Wash your hands after coughing or sneezing, using soap and water or an alcohol-based hand gel.
Follow all local health recommendations. For example, if you are sick, you may be asked to put on a surgical mask to protect others.
What to do if you feel sick:
It is expected that most people will recover without needing medical care.
If you have a severe illness or you are at high risk for flu complications, contact your health-care provider or seek medical care. Your health-care provider will determine whether flu testing or treatment is needed.
Avoid further travel for seven days after your symptoms begin or until you have been symptom-free for 24 hours, whichever is longer. This is to keep from infecting others and spreading the virus further.
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.
Avoid touching your eyes, nose or mouth. Germs spread this way.
Try to avoid close contact with sick people.
