According to the Butte-Silver Bow Health Department, one case of pertussis has been diagnosed in Butte.
The health department is having the male Butte High School student and his family remain home for 5 days.
The whole family is being treated, because they were in close contact. But none of them tested positive for whooping cough.
He was diagnosed May 2nd, him and his family have been on antibiotics ever since.
There is no more suspected cases at this point.
Butte High School nurse Shirley Gordon said she encourages community members to be on the look out for symptoms.
"It's not an epidemic and hopefully that's what it will stay at just one case, but if more come about then what we want to emphasize to students is if they are sick we want them to stay home. If they have a cough, especially if it's a violent cough then we want them to to to a doctor and get tested," Gordon said.
School nurses are on the look out as well as the emergency room and medical providers.
According to Karen Billson with the Butte-Silver Bow Health Department they are happy its just one person and they're keeping a close eye out and hoping for the best.
As of around 3 p.m. on Friday no more cases had been reported.
