Swine flu is contagious from one day before getting sick to five to seven days after.

More Info: According to the Centers for Disease Control, Swine flu, as known as H1N1 flu, is contagious and spreads similarly to any flu.  You can contract the swine flu by being near a person carry the virus either by direct contact through coughing, sneezing, or even talking, or indirectly by touching something that is harboring the flu virus then touching your nose or mouth.

How Long Should You Stay Out of Work?

The CDC recommends that those who have contracted influenza do not return to work a minimum of twenty-four hours after a fever has dropped below one-hundred degrees Fahrenheit without the assistance of fever-reducing medications.

According to a recent study nearly one in five patients still shed the flu virus for more than a week, with a few shedding the virus up to sixteen days later.

How a Family Member Affects Your Work Routine

If someone living in your household has contracted the influenza virus, you can still go to school or work as usual.  Because you can carry and spread the virus while you are asymptomatic, you should take extra precautionary measures to ensure that you don't spread the virus to others.  Watch for signs that you may be infected and be vigilant about your hygiene habits such as washing your hands often.
