Informational

Event

Health officials in California have confirmed at least 100 cases of norovirus throughout the state as of the end of April. According to local sources, the outbreak was linked to the consumption of raw oysters from four farms in the Canadian state of British Columbia.

Context

Norovirus is highly contagious and is spread by coming into contact with someone who is infected or touching surfaces or objects that have been contaminated. The most common symptoms are diarrhea, vomiting, nausea, and stomach pain. Diarrhea and vomiting can lead to dehydration, especially in young children, older adults, and people with other illnesses. There is no specific medication to treat norovirus.

Advice

To reduce the risk of contracting norovirus, wash hands regularly, particularly before eating or preparing food, thoroughly wash fruits, vegetables, and seafood. If you become sick, do not prepare food or care for others to avoid spreading the virus. Immediately clean and disinfect any surfaces that have become contaminated.
