What are the Symptoms of H1N1 flu?

Symptoms of the HINI virus infection are very similar to the seasonal flu. They include fever, cough, sore throat, body aches, headache, chills and fatigue. Diarrhea and vomiting have also been associated with H1N1 flu. Symptoms can vary from mild to severe.  Though it is not known if certain groups of people are at higher risk of developing H1N1 flu, it is possible those at higher risk of developing H1N1 flu may be the same as seasonal flu. Groups at higher risk of getting seasonal flu include pregnant women, persons with chronic medical conditions, children younger than 5 years old, and people who are immunosuppressed. There have been few cases of H1N1 virus in people over 65. 

If you suspect you or a member of your family has the flu, you should contact your doctor, who will be able to recommend a course of action. Most people will recover without medical care. However, if you are sick, you may be sick for a week or longer. You should stay home and avoid contact with others for at least 24 hours after your fever is gone without fever-reducing medication.
