US Health Officials Log 178 New Measles Cases as Oversight Shifts

The Centers for Disease Control and Prevention reported 178 new cases of measles in the United States this week, bringing the 2026 national total to 4,588. This figure is more than double the number of cases recorded in 2025. The data reflects ongoing transmission across at least 43 distinct outbreaks in the country.

Pennsylvania remains the epicenter of the spread, with state authorities reporting 1,338 cases as of Friday. South Carolina and Utah also report large outbreaks, with each state recording more than 500 cases. The CDC attributes the rise in numbers to the high contagiousness of the virus, which is widely regarded as one of the most transmissible diseases known to medicine.

Experts note that official tallies likely undercount the true prevalence of the disease. Common symptoms such as rash, fever, and cough often do not prompt immediate medical visits. When they do, the illness is severe for unvaccinated individuals. Hospitalization occurs in one in five unvaccinated patients, and death results from complications in one to three people per 1,000 cases. The measles vaccine prevents the disease in 97% of recipients, with common side effects limited to injection-site soreness and low-grade fever.

Discrepancies exist between state and federal death counts. Pennsylvania has reported five measles-associated deaths and is investigating a sixth. The CDC has officially recorded three national deaths but has not disclosed the location of the third case. This lack of clarity obscures whether the federal count includes a death from the Pennsylvania outbreak. According to Reuters, Health Secretary Robert F. Kennedy Jr. asked senior CDC officials in September to remove a specific death from the tally after questioning the disease's contribution.

The release of these case numbers coincides with administrative changes at the Health and Human Services Department. HHS announced this week that it will modify the vaccine adverse event reporting system, or VAERS. A new proposal will allow doctors to bill for reporting suspected vaccine injuries. VAERS has long been used by researchers to track rare safety issues, but it has also become a focal point for anti-vaccine activism.

Kennedy has reshaped vaccine oversight since taking office. He dismissed all 17 members of the expert panel that previously evaluated vaccine risks and benefits. He replaced them with ideologically aligned appointees, a move a court blocked in March. During his tenure, Kennedy has made public claims that children receive over 90 vaccine doses, linked vaccines to autism, and stated that the MMR vaccine contains aborted fetal debris. He also suggested vitamin A and cod liver oil may help treat measles, a position leading physicians described as misleading.
