A growing measles outbreak has been keeping American health professionals on alert, but experts say we should also be concerned about another vaccine-preventable disease: pertussis, commonly known as whooping cough. The illness typically presents with a harsh cough and can be especially dangerous for infants.
Whooping cough cases have "skyrocketed by more than 1,500% nationwide since hitting a recent low in 2021," said ProPublica. There have been "about 6,600 cases already in 2025," said CNN. Idaho, Louisiana, South Dakota and Washington have reported deaths this year.
These outbreaks tend to be a result of "populations with no immunity or reduced immunity," Lisa Morici, a professor of microbiology and immunology, said to CNN. Pertussis spreads through "coughing and sneezing and sharing close breathing space," pediatrician Alyssa Kuban said to the American Medical Association, noting that the "risk of spread is highest for the first one to two weeks that a person has symptoms." Without treatment, people can be contagious for several weeks. The highest-risk groups are young children and infants.
Doctors, researchers and public health experts warn that the recent measles outbreak "may just be the beginning," said ProPublica. Epidemics of preventable diseases like measles and whooping cough could "get much worse with falling vaccination rates" and the Trump administration "slashing spending on the country's public health infrastructure." Not only have national vaccination rates for measles, mumps and rubella fallen, but according to federal data, "so have those for pertussis, diphtheria, tetanus, hepatitis B and polio." |
