Most people who get the H1N1 swine flu virus will have a mild flu-like illness that does not require a doctor's visit or antiviral medications. In these cases, it's best to stay at home until you have had no fever (without the use of fever-reducing medications) for at least 24 hours. Be sure to cover coughs and sneezes with a tissue and wash your hands frequently to avoid spreading the virus.
