Missoula, MT — Missoula is currently experiencing a spike in whooping cough (pertussis) cases, with 22 reported instances, according to Missoula Public Health. Across the state of Montana, a total of 134 cases have been reported in 13 jurisdictions, primarily affecting younger populations, including teenagers and infants.
Infectious disease specialist Pam Whitney, who works with Missoula Public Health, emphasized the severity of the infection. “They don’t have air, they end up with severe vomiting and coughing fits,” she explained, noting that whooping cough can be especially dangerous for vulnerable populations, such as babies and the elderly, who are more susceptible due to weakened immune systems.
Symptoms of whooping cough include a persistent cough that can last for weeks or even months. Severe coughing fits may lead to a temporary pause in breathing, often followed by vomiting. The infection is known for its delayed onset, with symptoms typically appearing 9 to 10 days after exposure.
Whitney urged residents who believe they’ve been exposed to someone with pertussis or are experiencing symptoms to seek medical attention. “If you’ve been exposed or are showing symptoms, it’s important to see a healthcare provider. Antibiotics can help shorten the contagious period, and in some cases, just five days of treatment can reduce the time you need to be isolated. Without treatment, however, individuals could remain contagious for up to three weeks,” she said.
The disease is spread through the air when an infected person coughs or sneezes, and can also be transmitted through shared objects, like straws or utensils. Good hygiene practices, such as coughing or sneezing into the elbow and regular hand washing, are key to preventing the spread of the infection.
Vaccination remains the most effective method of protection against whooping cough. However, experts note that immunity can diminish over time. According to Whitney, children typically receive a booster shot around seventh grade, but there is often a gap in protection during the teenage years and early adulthood. “The pertussis component of the vaccine can wear off by the time individuals reach their 20s, which is why it’s important to stay vigilant,” she said.
Public health officials are advising anyone who thinks they may have been exposed to whooping cough or is showing symptoms to contact their healthcare provider promptly. Early intervention can help prevent further spread and reduce the severity of the illness.
As Missoula continues to grapple with this outbreak, health experts are urging residents to take precautions and stay informed about vaccination schedules to protect themselves and their communities.
