    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 developing ways to control and prevent injury, disability, and disease, including the swine flu. It responds to public health emergencies and helps states develop the appropriate responses.

    Confirmed case: An illness in one person that is confirmed by laboratory testing or by linking it to another laboratory-confirmed case. That means a case can be confirmed if the person has been exposed to a known, contagious infection. For example, if a child in your household tested positive for the swine flu, and you develop the same symptoms, you would be considered a confirmed case.

    Epidemic: An outbreak of an infectious disease that occurs in greater numbers than expected. The disease spreads rapidly among people.

    Hybrid Flu: A disease that occurs when genes from animal influenza viruses mix with human flu viruses. For example, the new virus responsible for the swine flu is believed to be a mix of pig, bird (avian), and human flu viruses. Hybrid flu viruses have caused pandemics twice in the past, in 1957 and 1968.

    H1N1 Virus: The most common subtype of influenza A, including the swine flu virus. The Department of Homeland Security and the Department of Agriculture want the swine flu to be referred to as the H1N1 virus so the pandemic does not negatively affect the pork industry. You cannot get the H1N1 virus from eating well-cooked pork. However, washing hands is recommended after visiting petting zoos or handling pigs. 

    Pandemic: An extreme infectious disease 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. The new swine flu virus could cause a pandemic if it is confirmed to easily spread from person to person and begins to cause severe illness all over the world.
