Influenza Information 2009-2010

Flu Overview

Influenza, or flu, is a respiratory infection caused by several flu viruses. The viruses pass through the air and enter your body through your nose or mouth.

Symptoms of the flu come on suddenly and are worse than those of the common cold. They may include:

  • Body or muscle aches
  • Chills
  • Cough
  • Fever
  • Headache
  • Sore throat   


Seasonal Flu

Seasonal flu is the term used to refer to the flu outbreaks that occur yearly, mainly in the late fall and winter. It is estimated that between 5 and 20 percent of Americans come down with the flu every flu season. Characteristics of strains of seasonal flu can vary from year to year, which is why there is a different flu vaccine developed each year.

For people 65 or older, newborn babies, and people with certain chronic illnesses, however, the flu and its complications can be serious—even life-threatening.

The vaccine for seasonal flu is available now. This vaccine does not protect against the H1N1 flu. It is important to get your seasonal flu vaccination, in addition to the upcoming H1N1 flu vaccine. It is encouraged to get your seasonal flu vaccine early.

2009 H1N1 Flu

H1N1, is a new influenza virus first detected in the United States in April 2009. It was originally referred to as Swine Flu because testing showed that many parts of this virus were similar to the flu viruses usually found in pigs. Cases of H1N1 have now been reported in most countries.

Symptoms of the H1N1 flu are the same as seasonal flu, although H1N1 symptoms can also include infection, vomiting and diarrhea. Just as with seasonal flu, symptoms can range from mild to severe. While symptoms may be similar, the high risk population for H1N1 flu is different.

Distribution of the vaccine could begin as early as October or November. Those recommended to receive the H1N1 vaccine when it first becomes available are:

  • Pregnant women
  • Persons between the agees of 6 months and 24 years old
  • People ages 25 through 64 who are at higher risk due to chronic health problems or compromised immune systems
  • People who live with or care for children younger than 6 months of age
  • Healthcare and emergency medical services personnel
