PINESDALE, Mont -

Pinesdale City Officials tell us that three cases of Whooping Cough have been confirmed.

People are witnessing a lot of coughing and sickness around town.

With the three confirmed cases, the Health Department and school administrators decided to close the school for this entire week. They want to be on the safe side.

Students are getting tested. It takes two days to get results back. If a test shows a child has whooping cough, health officials will treat the entire family.

We're told the school will make up this lost week in June.
