GREEN BAY, Wis. (WBAY) - Cases of the norovirus are popping up in Northeast Wisconsin, and some are mistaking it for the flu.
Often called the "stomach bug" Norovirus causes vomiting and diarrhea.
The norovirus attacks the stomach instead of your respiratory system.
"A lot of times you see it in nursing homes, day cares, and places where a lot of people gather," Prevea Nurse Practitioner Lingfei Zhang, DNP said.
Unlike the flu there is no treatment for the norovirus.
"The norovirus is something that has to run its course," Zhang said. "You can take some ibuprofen or a cold medicine that can help with the fever. People can normally resolve it within about 5 to 7 days."
The norovirus is year-round, but the most cases often flare up between November and April.
The Centers for Disease Control and Prevention said the best protections from the norovirus include washing your hands with soap and water.
Also make sure to handle and prepare your food safely.
Right now is also the peak time for flu cases, which can lead to some confusion about what's making you sick.
"Here in Wisconsin we do see influenza typically in the winter time and last year it was from November to January," said Zhang.
Prevea health centers report 26 flu cases so far this season.
14 of those cases were in the Green Bay area.
