Current Situation
Due to the circulation of 2009 H1N1 influenza in the United States and many other countries, airport staff in some foreign countries may check the health of arriving passengers. Many other countries, including Japan and China, are screening arriving passengers for symptoms of the flu.
If you are sick with symptoms of flu-like illness, you should not travel. These symptoms include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue. Some people may also have vomiting and diarrhea. People may be infected with the flu and have respiratory symptoms without a fever.
The United States is not screening travelers who arrive from other countries or depart for other countries.
In other countries that are conducting entry screening for 2009 H1N1 flu, travelers may be checked for fever and other symptoms of 2009 H1N1 flu, and their travel may be delayed. Consult the embassy of the country, or countries, in your travel itinerary for information about entry screening procedures. (October 15, 2009)
People need to realize that the 36K number being used as the annual death rate for seasonal flu involves mostly the elderly who catch the flu and then deteriorate into pneumonia.
Any highly infectious illness that kills people in their 30's and 40's (even if that rarely happens) is serious business. Just because the government is completely inept doesn't mean this is some kind of joke.
There is a thread here in chat were folks have posted about being extremely ill. Others have said it wasn't so bad.
