Norovirus is a very common and contagious virus. It causes very annoying acute gastroenteritis and is therefore considered a serious problem in the field of food safety. He is responsible for what we usually call “stomach flu” or “stomach virus”. Infections caused by norovirus occur above all in “crowded” contexts, in hospitals, retirement homes, schools or, typically, in confined environments, such as commercial and cruise ships.
We are talking about it because an ordinance from the mayor of Ponte di Legno (Brescia) has prohibited drinking tap water due to some cases of gastroenteritis in the Passo Tonale area.
