Norovirus cases spike in NYC: Here are things to know

NEW YORK (PIX11) -- Winter may be notorious for the flu, but right now there is another contagious virus spreading across New York City.

Sometimes known as the stomach flu or the stomach bug, the norovirus illness causes vomiting and diarrhea.

There have been 2,231 reported cases of the norovirus in the city since October, according to the New York City Health Department. Over half of the cases were reported in December.

What are the signs and symptoms?

Symptoms, including diarrhea, vomiting, nausea, stomach pain, fever, headache, and body aches, can develop 12 to 48 hours after exposure to the virus.

Vomiting and diarrhea may also lead to dehydration. People with the virus get better within one to three days but are still able to spread the virus for up to a couple of weeks after, according to the CDC.

How does the norovirus spread?

The virus can spread through direct contact with an infected person. This includes sharing food or eating utensils with them or consuming food they have handled.

Additionally, the virus can be transmitted if you touch contaminated objects or surfaces and then put your unwashed fingers in your mouth or eat food or drink beverages that are contaminated.

Prevention

• Wash your hands with soap and water for at least 20 seconds after changing diapers, touching common surfaces, shaking hands, and caring for people who are ill.

• Cook shellfish thoroughly and wash fruits and vegetables.

• Disinfect contaminated surfaces.

• Wash laundry in hot water.

• Stay home when sick for two days after symptoms stop.

Treatment

There is no specific medicine to treat norovirus. The CDC states that antibiotics are ineffective because they target bacteria, not viruses.

Those who contract the virus should drink plenty of liquids. In the case of severe dehydration, contact your doctor.
