A whooping cough epidemic is affecting Vermont, according to the Vermont Department of Health, which is calling on all adults 19 and older to get vaccinated.
As of last week, 522 cases of pertussis (as whooping cough is also known) had been reported statewide, Commissioner Harry Chen told a news conference Thursday. That’s more than 10 times the usual number for this time of year. More cases are being reported daily, state epidemiologist Patsy Kelso said.
About 90 percent of Vermont children have been vaccinated, Kelso said, but the immunization rate for adults is much lower, probably in the neighborhood of 10 percent. And adults are believed to be primarily responsible for spreading the disease, largely via coughing and sneezing.
Free clinics to administer the vaccine to adults will be open at regional health department offices Wednesday, Chen said. The adult booster, called Tdap, has only been available in Vermont since 2006, so most people probably have not received it. Tdap also immunizes against tetanus and diphtheria.
