Causes & Risk Factors
cause
Flu viruses are spread through the air when an infected person coughs, sneezes or talk. You can inhale the virus directly, or through an object such as a phone or computer keyboard, and then deliver them to the eyes, nose or mouth.
Flu is caused by three types of viruses - influenza A, B, and C. Type A causes deadly flu pandemic (an epidemic in the hemisphere) that strikes every 10 to 40 years. Type B causes a pandemic with a smaller scale. Type A or B can cause the flu every winter circulation. Type C is never associated with a large epidemic.
Type C is quite stable, but type A and B are constantly changing and raises new concerns for the community on a regular basis. Once you have the flu, the antibodies will suppress the cause, but it will not protect you from the virus that has mutated. That's why doctors recommend a flu shot every year.
risk factors

• Having a weak immune system, such as HIV-AIDS.
• Pregnant when will the flu season
• Residents in care centers.
• Working in the care center.
• Regularly perform in close contact with infants or children.

If your child is not at risk but stay with people who have these risks, you still have to give the vaccine to your child. The way your child will reduce the risk of infection. More and more people are immunized, fewer flu will spread in a community.
