Norovirus is serious business but how is it passed on?
It can live for weeks — yes, weeks — on a hard surface, so transmission can occur by touching any given surface long after another a person infected the area.
The wretched virus can spread by other routes, including via contaminated food.
However, it has been thought that the norovirus can also move as an aerosol, which is defined as the suspension of ultra-microscopic particles in the air.
