A five-week-old baby has died of whooping cough in San Diego, the second infant death from the disease in California this year.
The otherwise healthy baby died on Friday, NBC San Diego reports. Officials have not revealed further details on the case.
Newborns are especially susceptible to the disease because they are too young for full vaccination; pregnant women and people who come in close contact with infants are advised to get vaccinated for the disease, which is also known as pertussis.
The CDC recommends that all children receive at least five doses of the vaccine before kindergarten, and a booster is necessary before seventh grade. Pregnant women also typically receive the adult version of the booster in their third trimester.
