How is flu spread?

Flu is spread by the droplets that are produced when someone who is sick coughs, sneezes, or talks.  These droplets can land in another person's nose or mouth who are within close distances and spread the flu.  Flu can also be spread by touching a surface or object that has these droplets on them and then touching your mouth, eyes or nose.

Is there a treatment for flu?

There is no treatment for the flu. Some antiviral drugs are available  that may reduce the severity of illness after a person has the flu.  These antiviral drugs should be taken within 48 hours of feeling ill and require a prescription from your primary health care provider.  Otherwise, bed rest, drinking lots of liquids and taking pain relievers to help reduce the discomfort of illiness is recommended.  Children should NOT be treated with aspirin due to the risk of developing Reye's syndrome.

What is Avian H7N9 Influenza?

Influenza A H7N9 viruses are a subgroup of influenza viruses that normally circulate among birds. Recently in China there have been reports of human infections for the first time from these viruses. However, there is no evidence to date that H7N9 can be transmitted human-to-human, and there have been no reported cases in the United States. Any time a new influenza subtype is discovered in humans it is a public health concern. The Center for Disease Control (CDC) is monitoring the situation closely.
