Symptoms of Norovirus
People of all ages can get infected and sick with norovirus. The most common symptoms of norovirus are diarrhea, vomiting, nausea, and stomach pain. Other symptoms include fever, headache, and body ache.
A person usually develops symptoms 12 to 48 hours after being exposed to norovirus. Most people with norovirus illness get better within 1 to 3 days.
If you have norovirus illness, you can feel extremely ill, and vomit or have diarrhea many times a day. This can lead to dehydration, especially in young children, older adults, and people with other illnesses. Symptoms of dehydration include decrease in urination, dry mouth and throat, and feeling dizzy when standing up. Children who are dehydrated may cry with few or no tears and be unusually sleepy or fussy.
If you think you or someone you are caring for is severely dehydrated, call your healthcare provider.
Recommendations for Restaurants and Retailers
Restaurants and retailers should not sell/serve the potentially contaminated oysters. Restaurants and retailers should dispose of any products by throwing them in the garbage or returning to their distributor for destruction.
