Stomach virus spreading across Northeast: CDC

NEW YORK (PIX11) – The Northeast region of the U.S. currently has the highest positivity rate for a stomach virus called norovirus, according to CDC data.

The three-week average for positive norovirus tests in the Northeast region is at over 15%, CDC data showed. In comparison, positive norovirus tests are reported to be around 10% in the Southern region, 9% in the Midwest and 12% in the Western region.

Norovirus causes vomiting, diarrhea and stomach cramps. Other symptoms include fevers, headaches and body aches.

People exposed to the virus usually show symptoms within 12 to 48 hours, according to the CDC. Those who were infected will likely start feeling better between one to three days, but can spread it for several days after.

Dehydration is common for those with norovirus, especially in young kids, older adults and those with underlying illnesses, health officials said.

There are around 19 to 21 million norovirus cases in the U.S. every year, according to the CDC. There are an average of 900 deaths, 109,000 hospitalizations and 465,000 emergency room visits for norovirus, data showed.
