Norovirus is highly contagious and has a rapid transmission capacity. Outbreaks occur en masse in communities, schools, restaurants, hospitals, and other places. Just like a cold, as long as the symptoms are treated in a timely and appropriate manner, the symptoms will improve and heal themselves in about 3 days. However, the elderly, infants and people with underlying diseases, there may be serious complications, for serious patients, especially young children and the weak should be timely oral rehydration or infusion, in order to prevent dehydration, acidosis and electrolyte disorders. ”

Frequent vomiting and diarrhea can lead to dehydration, electrolyte abnormalities, and metabolic acidosis. ”

Not effective against norovirus

Not a substitute for washing your hands
