Norovirus in Kerala
State health officials say Norovirus is spread through water and food particles.
Health officials say that norovirus infections usually only last for two days and don’t have many consequences afterward.
However, health officials say Norovirus can cause dehydration in the very young and old, and in some patients, the body will remain weak for another week after infection.
