Norovirus infection is an extremely contagious infection, caused by the norovirus. It spreads very easily through contaminated food and water and also through direct contact with the infected person or surface.(1,2)
There are various types of noroviruses. However, an infection from one type does not give you immunity from an infection of the other type.

The symptoms may make you quite miserable for a couple of days. But usually, they get better on their own and are nothing to unduly worry about.(2)
What Is The Best Treatment For Norovirus Infection?

There is no precise treatment for norovirus infection. The revival from this infection depends upon how good your immune system is. However, it usually gets better in most people within a few days, on its own.

An anti-diarrheal medication that is usually available over the counter, may be recommended by your doctor.
