Type A Influenza

George was also to be found to be suffering from Type A Influenza at the time of his death.

The flu, more scientifically known as influenza, is a highly contagious respiratory infection caused by influenza viruses. The influenza virus usually enters the body through mucus membranes in the mouth, nose, or eyes.

When a person with the flu coughs or sneezes, the virus then becomes airborne and can be inhaled by anyone nearby. You can also get the flu if you’ve touched a contaminated surface like a telephone or a doorknob and then touch your nose or mouth. Of course, the risk of infection is greater in highly populated areas like schools, buses, and crowded urban settings.

Who is at risk?

In most communities, school-age children are the first age group to get the flu. They then carry the virus home and to after-school activities where they interact with other kids. The flu virus is usually prominent from October through May, the time of year typically known as “flu season.”

Older adults, young children, and people with specific health conditions are at higher risk for serious flu complications.

Influenza A immunisation is given as part if flu vaccine annual Programme to children with asthma and other chronic conditions from age of 4 yrs not younger.

Is It a Cold or the Flu?

The cold and flu are both respiratory illnesses, but they are caused by different types of viruses with different symptoms. Use this chart to learn the difference between the two.

Fever Usual; lasts 3-4 days Rare
Aches Usual; often severe Slight
Chills Fairly common Uncommon
Fatigue, weakness Usual Sometimes
Sneezing Sometimes Common

Types of Flu

There are 3 types of flu viruses. Type A viruses are found in many kinds of animals, including ducks, chickens, pigs, and also humans. The Type B virus widely circulates in humans. Type C has been found in humans, pigs, and dogs, and causes mild respiratory infections, but does not spark epidemics.

Influenza virus is one of the most changeable of viruses. Changes may be small and continuous or large and abrupt.

Influenza Type A is divided into subtypes that can be found worldwide and include H1N1, H1N2, and H3N2 viruses.

Influenza Type B outbreaks can also cause epidemics, but the illness it produces is usually milder than Type A.

Influenza Type C flu viruses are not thought to cause a large epidemic and generally cause only mild respiratory infections.
