(KMOX) - More than 170 people have gotten sick recently with a gastrointestinal illness after visiting Yosemite National Park, including two confirmed cases of norovirus.

Park officials say most of the cases happened during the first week of January. While only two cases have been confirmed so far, most of the people affected have symptoms "consistent with norovirus," according to a statement from the National Parks Service.

Norovirus is highly contagious and can cause vomiting, diarrhea, fever, and stomach pain. Those infected typically start to develop symptoms within 24-48 hours after exposure, then it usually wears off in a couple of days.

An investigation into the outbreak is underway, as Yosemite National Park officials and medical professionals with the National Park Service Office of Public Health are interviewing those who have fallen ill.
