Why do we get Influenza?
The infection is spread through the air. Therefore, someone suffering from it may sneezes or cough leaving the infection in the air and infecting other people. One inhales the droplets or can pick up the germs by hand. They end up touching their nose and mouths.
There are different types of flu viruses. The body has antibodies that help us fight these viruses. Therefore one can easily resist the virus. However, some of these viruses are too strong for antibodies. The antibodies end up not protecting us.
Are you over half an year or older? Doctors really recommend that you get the flu vaccine once a year. This vaccine reduces the risk of the virus. It also helps prevent getting other diseases that are so serious. The great news is that recent vaccines help prevent at least four types of flu viruses.
