You can catch flu -
Cause & Risk
The flu virus is contained in the millions of tiny droplets that come out of the nose and mouth when someone, who is infected, coughs or sneezes. These droplets typically spread about one metre. They hang suspended in the air for a while before landing on surfaces, where the virus can survive for up to 24 hours. Anyone who breathes in the droplets can catch flu. And anyone who touches the surfaces droplets have landed on can also catch flu if they pick up the virus on their hands and then touch their nose or mouth. Everyday items at home and in public places can easily become contaminated with traces of flu virus including food, door handles, the remote control, handrails, telephone handsets and computer keyboards. So, it's important to wash your hands frequently to prevent catching and spreading flu.
The symptoms of flu will usually peak after two to three days and you should begin to feel much better within five to eight days. However, you may have a lingering cough and still feel very tired for a further two to three weeks. Flu can give you any of these symptoms: sudden fever -
Diagnosis & Treatment
If you are otherwise fit and healthy, there is usually no need to visit your G.P. if you have flu-
If you become infected with a flu virus your body will produce antibodies against it. Antibodies are proteins that recognise and fight off germs that have invaded your body. Your antibodies will remember this flu virus and fight it if it invades your body again. But, over time the flu virus can change into a different version or strain, which means your body may not recognise it and you can catch flu again. When the virus changes to a new strain that people have little or no resistance to, it can cause a flu pandemic, which means it can spread globally. This is what happened in the swine flu pandemic of 2009.
