King County officials a newborn has died of whooping cough.
It’s the first death from whooping cough in Washington this year.
The infant died Thursday. Health officials did not identify the family, nor any details about where the family lived.
This year there have been 757 confirmed cases of pertussis reported among King County residents, the highest number the county has seen in over a decade, according to Public Health Seattle & King County.
Infants are at the highest risk for serious illness, hospitalization or death from whooping cough. County officials say that vaccinating the mother, ideally between week 27 and 36 of her pregnancy, provides temporary immunity until the baby, at 2 months of age, is old enough to be immunized.
Health officials say that family members and other close contacts should be up-to-date with their pertussis vaccines as well.
