CDC: The Centers for Disease Control and Prevention, a branch of the Department of Health and Human Services. The Atlanta-based federal agency helps promote and protect your health by finding ways to control and prevent injury, disability, and disease, including swine flu. It responds to public health emergencies and helps states create a response.
Confirmed case: An illness in one person that is confirmed by a lab test or by linking it to another case that was confirmed in a lab. A case can be confirmed if the person was exposed to a known, contagious infection. For example, if tests show a child in your household has swine flu, and you get the same symptoms, you would be a confirmed case.

Epidemic: An outbreak of an infectious disease that affects more people than expected. The disease spreads rapidly from person to person.
Hybrid flu: A disease created when genes from animal influenza viruses mix with human flu viruses. For example, one virus that causes swine flu is believed to be a mix of pig, bird (avian), and human flu viruses. These types of viruses caused huge outbreaks in 1957, 1968, and 2009.
H1N1 virus: The most common subtype of influenza A, including the swine flu virus. The Department of Homeland Security and the Department of Agriculture call swine flu the H1N1 virus so outbreaks won’t stop people from eating pork products. You can’t get the virus from eating well-cooked pork. But you should wash your hands after you visit a petting zoo or touch pigs.
Pandemic: An outbreak that affects the entire world. Type A influenza viruses are the only ones known to have caused pandemics. In 1918, the Spanish flu pandemic killed 40-50 million people worldwide. Swine flu caused severe illness worldwide in 2009.
Rapivab (peramivir): An antiviral drug that prevents and treats flu in adults aged 18 and over. It stops the virus from spreading in your body. This eases your symptoms and helps you get better sooner. You take it in one dose.
