ST. LOUIS (KMOV.com) -- A nasty stomach virus is affecting the St. Louis area.
Health officials said an outbreak of the Noro-virus is infecting people in eight area locations throughout St. Louis.
Officials said they have no way of knowing just how many people have the Noro-virus, because it does not have to be reported.
Doctors said there is no known cure for Noro-virus, but the symptoms are treatable.
Doctors said the highly contagious illness causes diarrhea, vomiting and stomach cramps that usually last one to two days.
The virus is most common where people are in close quarters. In St. Louis County six nursing homes said they have seen an outbreak in their buildings.
The Centers for Disease Control reports the Noro-virus causes 70,000 hospitalizations and 800 deaths a year.
Dr. Laurie Byrne at St. Louis University hospital said she sees multiple cases of Noro-virus a day. Dr. Byrne said a few doctors at the hospital were home sick with the bug today as well.
"The regular person who’s relatively healthy, you’re going to get over this,” said Dr. Byrne, “The worst is the first 12-24 hours; get over that hump, take in fluids you'll be fine."
