- Anybody who touches these exteriors can transmit the germ by touching anything else.
- Ordinary objects at home and in communal places might have traces of the virus. These consist of door handles, handrails, remote control, food and PC keyboards.
- People generally become ill by picking up the germ on their hands from unclean items and then putting their hands near their nose and mouth.
