Anyone who touches infected surfaces can spread the virus by touching anything else. The virus is also transmitted by infected people who cough or sneeze into their hands and then touch other people or objects before washing their hands.
Everyday items at home and in public places may have traces of the virus. These include food, door handles, remote controls, hand rails, paper money and computer keyboards.
People usually become infected by picking up the virus on their hands from contaminated objects and then placing their hands near their mouth or nose. It is also possible to breathe in the virus if it is suspended in airborne droplets.
Good hygiene, such as hand washing and cleaning, is the most effective way of slowing the spread of flu. Antiviral medication and the seasonal flu vaccine are also offered to people at risk, but remember after taking vaccination it takes few weeks to make your body protected against seasonal flu.
