The Centers for Disease Control and Prevention (CDC) confirmed on Sept. 23 that a measles-related death occurred in the United States, marking the first verified fatality from the disease in 2024. The agency stated that measles was listed as the underlying cause of death on the death certificate, following a review by the CDC’s National Center for Health Statistics (NCHS).
The CDC noted that the death count is subject to change and will be updated as additional information becomes available. The agency did not specify which state or individual was involved in the confirmed death. Pennsylvania officials previously reported four measles-associated deaths in the state, though local coroners indicated one of those cases was unrelated to measles. The CDC declined to clarify whether the newly confirmed death corresponds to one of the Pennsylvania cases.
Measles cases surge amid declining vaccination rates
The CDC has recorded more than 3,400 measles cases across 45 states and Washington, D.C. in 2024, the highest annual total in three decades. Health experts warn that vaccination rates have fallen below the 95% threshold required to maintain herd immunity, increasing the risk of outbreaks. Measles is among the most contagious viruses, with a 90% transmission rate among unvaccinated individuals exposed to an infected person.
Symptoms include high fever, cough, runny nose, and a characteristic rash appearing three to five days later. Severe complications, such as pneumonia and encephalitis, can occur, though vaccination significantly reduces these risks. Public health officials have linked recent exposures at high-traffic locations, including Philadelphia International Airport, to potential transmission chains.
State and federal responses diverge on measles tracking
Pennsylvania’s Department of Health reported four measles-associated deaths in recent weeks, though coroners disputed one case’s connection to measles. The state formally requested federal assistance on Sept. 16, contingent on CDC recognition of the deaths as measles-related. However, Pennsylvania officials stated they are unaware of which death the CDC is citing.
Federal health agencies emphasized that their reporting remains provisional. A spokesperson for the Department of Health and Human Services, the CDC’s parent agency, stated that the death count is based on standard verification processes and may be adjusted as reviews continue.
Public health experts call for renewed vaccination efforts
Infectious disease specialists, including Dr. Geetika Sood of Johns Hopkins School of Medicine, warned that measles spreads rapidly in unvaccinated communities. Sood noted that many cases go unreported due to underdiagnosis, particularly among those avoiding medical care. The CDC’s confirmation of a measles death follows heightened concerns over declining immunization rates and the resurgence of a disease declared eradicated in the U.S. in 2000.
Health officials continue to urge vaccination as the primary preventive measure, citing its role in reducing severe outcomes. The CDC’s update comes as federal and state agencies assess the scope of the outbreak and coordinate response efforts.
