MISSOULA – Local health officials report they are looking into six whooping cough cases in the Missoula area.

Sentinel High School sent out a message to parents on Tuesday of three confirmed pertussis cases at the school.

The Missoula City-County Health Department reports a total of six cases and has identified more than 300 close contacts who may have been exposed to the disease.

The ages for the confirmed cases range from preschool through teenager, with one case requiring hospitalization. Health officials also note that there are more suspected cases of pertussis that are pending laboratory results.

There is a mix of unvaccinated and vaccinated children among the cases, according to the health department.

The health department is working directly with the affected families and the schools the ill children attended to identify close contacts, according to a news release.

Pertussis is spread by respiratory droplets, so while it is highly contagious, not everyone who goes to the same school as a child with pertussis is considered a close enough contact to have been exposed.

The health department notes that when close contact is identified, they will notify the child and the child’s parents.

It’s being asked that parents not call the health department or their child’s school to determine if their child has been exposed. For other questions about pertussis, please call the health department pertussis information line at (406) 258-INFO.

With an outbreak underway in the Missoula area, there may be more active cases of pertussis in the community that health officials don’t know about yet.

If treated in its early stages, pertussis symptoms can be reduced, and close contacts who have been exposed can be protected from developing the disease.

Anyone experiencing the pertussis symptoms described below should contact their healthcare provider or go to a walk-in clinic for testing. Immunization provides good but not full protection against pertussis, so people can get the disease even when vaccinated.

Pertussis, also known as “whooping cough,” typically begins with cold-like symptoms, including a runny nose, mild occasional cough, sneezing and low-grade fever.

Later symptoms include a persistent cough with fits of coughing severe enough that exhaustion, vomiting or a whooping sound may occur as the patient tries to catch their breath.

Symptoms can be more severe in unvaccinated individuals, babies less than a year old and those with compromised immune systems.

Residents are encouraged to check their vaccination status by calling their doctor or the health department’s Immunization Clinic at (406) 258-3363.

People who have not received the full pertussis series, including a booster, and women who are pregnant, even if they were fully immunized before pregnancy, are urged to update their vaccinations.
