Missoula Public Health is alerting the community that pertussis (whooping cough) is circulating in the area. Pertussis is a highly contagious respiratory illness that can cause severe coughing fits. This illness is especially dangerous for infants, pregnant individuals, and those with weakened immune systems. Since December 2024, Montana has seen 140 cases in 13 jurisdictions and Missoula County has had 22 pertussis cases reported.
Pertussis often begins with mild cold-like symptoms and can progress to severe coughing spells. Anyone experiencing symptoms should seek medical attention, especially if they’ve been in close contact with someone diagnosed with pertussis.
Symptoms may include:
- Persistent cough lasting more than two weeks
- Severe coughing fits, sometimes followed by a “whooping” sound
- Vomiting after coughing
- Difficulty breathing, especially in young children
- Apnea (pauses in breathing), particularly in infants
If you suspect you may have pertussis: - Seek medical care – a healthcare provider can evaluate symptoms and perform a test for pertussis.
- Follow treatment guidelines – if diagnosed, antibiotics can help reduce the severity and prevent further spread.
- Stay home if sick – avoid contact with others, especially infants and vulnerable individuals.
How to prevent the spread of pertussis: - Get vaccinated – the Tdap and DTaP vaccine is the best protection against pertussis. It is recommended for:
o Infants and children as part of the DTaP series
o Pregnant individuals (during each pregnancy)
o Adults who have never received a Tdap booster
o Anyone in close contact with infants or high-risk individuals - Practice good hygiene – wash hands frequently, cover coughs and sneezes, and disinfect commonly touched surfaces.
- Limit exposure – avoid close contact with individuals who are sick, especially in group settings like schools and childcare facilities.
Missoula Public Health urges the community to take precautions to help stop the spread of pertussis. For more information or vaccination resources, contact Missoula Public Health at 406-258-3896.
