Influenza Tests:

Influenza (the flu) is a viral respiratory infection that tends to be seasonal, usually beginning in late fall and disappearing in early spring. It is a common respiratory illness that affects 30 to 50 million Americans each season.

Symptoms of influenza (headaches, fever, chills, muscle pains, exhaustion, a stuffy nose, sore throat, and a cough) tend to be more severe and longer lasting than the flu-like symptoms caused by the common cold. According to the CDC (Centers for Disease Control and Prevention), about 36,000 people a year die from flu-related complications in the U.S. and more than 200,000 people are hospitalized, especially the very young, elderly, those who are pregnant, and those with compromised immune systems or pre-existing lung disease

There are two types of influenza

A and B, that commonly infect humans, and each virus can mutate to develop different strains. Usually a single strain of influenza virus A will predominate during a particular flu season, although there may be a mixture of A and B causing outbreaks in the community at the same time.

For the 2009-2010 flu season, there was a seasonal influenza A strain as well as a new strain identified as 2009 H1N1 influenza A (sometimes called swine flu). According to the CDC, this new strain has caused the majority of influenza infections in 2009-2010, and the World Health Organization (WHO) has declared the 2009 H1N1 virus a pandemic, since it caused multiple influenza outbreaks throughout the world at the same time

Flu testing relies on

detecting either the virus that is being shed in the respiratory secretions or detecting antibodies directed against the virus in the blood of the person infected. In nasal secretions, detectable virus is usually only shed for the first few days that a person is ill, so most testing must be done during this time period.

Antiviral medications have been developed to treat either influenza A alone, or both A and B. These medications, if given within 48 hours of the onset of symptoms, can reduce the severity of symptoms and reduce the time that a person is sick by about a day.

Influenza testing can be used to help diagnose the flu and determine treatment options for an individual person, and it can be used to help rule out the flu when looking for other illnesses.
