H1N1 Influenza

How does H1N1 flu spread?

Human-to-human transmission of H1N1 flu is thought to occur in the same way as seasonal flu occurs in people, which is mainly person-to-person transmission through coughing or sneezing of people infected with the influenza virus. People may become infected by touching something with flu viruses on it and then touching their mouth or nose.

How long can an infected person spread H1N1 flu to others?

People with H1N1 influenza virus infection are potentially contagious 1 day before showing symptoms, and 24 hours after their fever breaks.

What can I do to protect myself from getting sick?

Take these everyday steps to protect your health:

Can I get H1N1 influenza from eating or preparing pork?

No. H1N1 influenza viruses are not spread by food. You cannot get H1N1 influenza from eating pork or pork products. Eating properly handled and cooked pork products is safe.

Is cold water adequate for hand washing?

Cold water is considered effective if the soap is soluble in cold water. Tepid or warm water is recommended by the CDC however, cold water is also acceptable if the soap used mixes well with cold water. Warm water does have the advantage of removing oils from the hand and making soap more soluble while excessively hot water is harder on the skin, dries the skin, and is too uncomfortable to wash for the recommended amount of time.

At this time, the CDC does not generally recommend using respirators or masks for H1N1. Certain groups such as the following may be advised to use a respirator/mask:

The optimal use of a respirator requires fit-testing and medical clearance for use. Masks should be considered as an alternative. More information can be found at the CDC website.

How can I get a mask?

The University is providing masks on a limited basis based on the current CDC Interim Recommendations for Facemask and Respirator Use to Reduce Novel Influenza A (H1N1) Virus Transmission. If you are a University employee and meet the CDC requirements, speak to your supervisor and a mask can be provided. If you are a student, you can obtain masks at your nearest pharmacy.

Do I need to disinfect my workspace?
