The Pan American Health Organization has determined that the United States no longer maintains measles elimination status, concluding this week that the disease has reestablished regular transmission in the country. The determination will be announced on Nov. 17. Under public health definitions, measles elimination requires that sporadic outbreaks end within one year, a condition no longer being met in the United States.
The resurgence has resulted in substantial health and economic impacts. Over the past two years, more than 830 people have been hospitalized with measles, and outbreaks have sickened more than 8,000 individuals. Thirteen measles-associated deaths have been reported by states, including infants in recent months who were too young to receive vaccination. Researchers estimate the outbreaks have cost approximately $125 million in medical care, public health response, and lost productivity. The MMR vaccine is approximately 97% effective at preventing infection with two doses.
Expert assessments attribute the measles resurgence to declining childhood vaccination rates, which have steadily decreased since the COVID pandemic began. PAHO’s determination followed analyses by the CDC and an independent group of measles experts. The Utah outbreak, which surpassed the one-year duration mark in June, provided an indication that elimination status would be lost. A former CDC official noted that measles causes significant suffering, ranging from high fevers and missed school to long-term neurological complications.
The loss of elimination status represents a reversal of gains achieved over more than 30 years of public health efforts. The U.S. had secured measles elimination in 2000 after implementing vaccination initiatives, including the Vaccines for Children program to provide free immunizations to underinsured families. Occasional imported cases had previously been contained by herd immunity when approximately 95% of communities were vaccinated. The current situation differs markedly from earlier disease control efforts, when federal officials held press conferences and coordinated national vaccination campaigns in response to outbreaks.
