More cases of stomach virus confirmed, still none in Okla.

CDC sign

Officials have confirmed more cases of a stomach virus rapidly spreading across the U.S.

Now at least 275 cases of cyclospora have been confirmed; at least 10 people have been hospitalized.

Officials said they believe the illness is linked to contaminated produce but they have not identified the source.

Seven states have confirmed cases including Iowa, Nebraska, Texas, Wisconsin, Georgia, Connecticut and New Jersey.

So far, no cases have been reported in Oklahoma.

Symptoms include diarrhea, loss of appetite, fever and fatigue.

Doctors said it can last for weeks but it can be treated with antibiotics.

Health experts said the best thing to do to avoid the illness is to make sure you wash all your fruits and vegetables before eating them.
