PANDEMIC 2009 H1N1 INFLUENZA
Pandemic Influenza is a worldwide outbreak of illness that occurs when a new influenza virus appears and spreads easily from person to person because our bodies have little or no immunity.
2009 H1N1 Influenza Virus
On June 11, 2009 the World Health Organization (WHO) declared a global pandemic of novel influenza A H1N1 (formerly known as Swine Flu) and raised the WHO phase of pandemic alert to Phase 6. The virus is now being referred to as "2009 H1N1 influenza."
The Centers for Disease Control and Prevention (CDC) has determined that 2009 H1N1 is contagious and is spreading from human to human. The symptoms of 2009 H1N1 flu virus are similar to the symptoms of seasonal flu and generally include fever (over 100 degrees Fahrenheit) with cough and/or sore throat. Other symptoms may include runny or stuffy nose, body aches, headache, chills and fatigue. The most important actions to take are: maintain good hygiene, proper cough and sneeze etiquette, and anyone with flu-like illness should stay home until they are free of fever for 24 hours without using fever-reducing medication.

Due to the fact that the 2009 H1N1 pandemic is a dynamic situation and guidance can change rapidly, many of the links on the right will redirect to the current webpage for the State of Wisconsin or the CDC.

Flu Terms Defined
Seasonal (or common) flu is a respiratory illness that can be transmitted person to person. Most people have some immunity, and a vaccine is available.
Pandemic flu is virulent human flu that causes a global outbreak, or pandemic, of serious illness. Because there is little natural immunity, the disease can spread easily from person to person.
2009 H1N1 flu (formerly Swine Flu) is a new influenza virus causing illness in people. This new virus was first detected in the U.S. in April 2009, and has spread to many countries around the world.
Bird flu is commonly used to refer to Avian flu (see below). Bird flu viruses infect birds, including chickens, other poultry and wild birds such as ducks.
Avian flu (AI) is caused by influenza viruses that occur naturally among wild birds. Low pathogenic AI is common in birds and causes few problems. Highly pathogenic H5N1 is deadly to domestic fowl, can be transmitted from birds to humans, and is deadly to humans. There is virtually no human immunity and human vaccine availability is very limited.
