Norovirus is highly contagious, but there are ways to protect yourself and other family members if someone in your household falls ill.
According to the NHS, norovirus can be transmitted through close contact with an infected person, touching contaminated surfaces or objects and then touching your mouth.
Food prepared or handled by a sick person can also be a breeding ground for the virus. And alcohol hand gels do not kill the norovirus bacteria.
However, there are some strategies to combat it, starting with avoiding situations that may contribute to its spread, such as close contact with potentially infected people or surfaces.
