The Wyoming Department of Health (WDH) is raising awareness about pertussis, or whooping cough, as cases increase across the state, including an ongoing outbreak in Sheridan County, Buckrail reports.
At least 10 cases have been reported in Sheridan County in recent weeks, with additional cases confirmed in Campbell, Johnson, and Lincoln counties. So far in 2024, 18 total cases have been reported, according to WDH Infectious Disease Epidemiology Program Manager Clay Van Houten.
“That brings us to 18 reported cases so far this year, and we’re only in the year’s second month,” Van Houten said.
By comparison, Wyoming saw 19 cases in all of 2024, while zero cases were reported in 2023 and only two cases in 2022. The WDH noted that actual case numbers are likely higher because some infections go unrecognized or unreported.
Health officials are particularly concerned about infants, as more than half of babies under one year old who contract whooping cough require hospitalization. While no hospitalizations have been reported in Wyoming so far this year, Van Houten emphasized the importance of vaccination to protect the most vulnerable.
“If you are pregnant or planning on becoming pregnant, you should talk to your doctor about a Tdap vaccine, which can help protect infants,” Van Houten said.
The Tdap booster vaccine is also recommended for parents, grandparents, and caregivers who spend time with newborns. The WDH encourages all Wyoming residents to stay up to date on their pertussis vaccinations, as those who are vaccinated are less likely to develop severe infections.
Whooping cough often starts with mild, cold-like symptoms and may not be recognized right away. After one to two weeks, it can develop into a persistent cough with spasms, sometimes producing a distinctive “whooping” sound—especially in infants and young children.
Because pertussis has become less common in the US due to widespread immunization, it is not always diagnosed right away, Van Houten explained.
The WDH urges residents to be aware of symptoms, seek medical attention if needed, and ensure vaccinations are up to date to help prevent further spread.
