Additional confirmed pertussis cases reported in Missoula area

MISSOULA – The number of confirmed whooping cough cases in the Missoula area has now risen to 57.

Pertussis cases have been confirmed in several Missoula County Public Schools — including Big Sky, Hellgate and Sentinel high schools.

Whooping cough cases have also been reported the Florence, Frenchtown and Lolo school districts.

The Missoula City-County Health Department is still working with schools to identify close contacts of confirmed cases.

Local health officials previously told MTN News that due to the number of calls the department has been receiving about the pertussis outbreak, they’ve asked part-time nurses to work full time for the next couple of weeks.

The Health Department will contact people with instructions if action is needed or will send information home with your child.

People can call the health department at (406) 258-4770 to check your records or get general information. A dedicated webpage with pertussis information has also been established to relay the latest information.


Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by a type of bacteria. It can affect people of all ages but can be very serious, even deadly, for babies less than a year old.

Pertussis symptoms can appear differently and be less severe in vaccinated individuals, but can still be contagious.

Symptoms

  • Pertussis is known for uncontrollable, violent coughing which often makes it hard to breathe. After coughing fits, someone with pertussis often needs to take deep breaths, which result in a “whooping” sound.
  • Symptoms of pertussis usually develop within 5 to 10 days after you are exposed. Sometimes pertussis symptoms do not develop for as long as 3 weeks.
    Early Symptoms
  • The disease usually starts with cold-like symptoms and maybe a mild cough or fever. In babies, the cough can be minimal or nonexistent.
  • Early symptoms can last for 1 to 2 weeks and usually include runny nose, low-grade fever, mild, occasional cough, or Apnea – a pause in breathing (in babies)
  • Pertussis in its early stages appears to be nothing more than the common cold.

Later-stage Symptoms

  • After 1 to 2 weeks and as the disease progresses, the traditional symptoms of pertussis may appear and include fits of many, rapid coughs followed by a high-pitched “whoop” sound, throwing up during or after coughing fits, and exhaustion.

Pertussis in Babies

  • It is important to know that many babies with pertussis don’t cough at all. Instead it causes them to stop breathing and turn blue.

How and When to Get Help

  • If you are experiencing symptoms of Pertussis, see your provider right away.
  • If you or a family member has been identified as exposed, you will receive instructions from the Health Department.
  • The best way to protect against pertussis is by getting vaccinated. Make sure that you and your family are up to date on your immunizations.
  • If you need information on your immunization status, contact your provider or the Health Department.
