US Measles Outbreaks Cost Nearly $83 Million in 2026

Measles outbreaks across the US this year carry an estimated economic cost of nearly $83 million, most of it tied to the public health response, according to a new tool from Johns Hopkins University, as reported by CNBC.¹

The estimate comes as the country faces its worst measles outbreak in more than 3 decades. CDC data show 5182 confirmed cases in 2026 as of November 5, reported by 47 jurisdictions and international visitors, with 43 new outbreaks this year and 96% of cases linked to outbreaks.² That compares with 2289 cases in all of 2025 and 285 in 2024. The CDC lists 4 deaths this year, a figure the agency notes is subject to change; CNBC reported 8 confirmed measles-associated deaths in 2026: 6 in Pennsylvania, 1 in New York, and 1 in Wisconsin.¹

Public Health Response Accounts for Most of the $83 Million

Of the estimated 2026 total, about $56 million stems from the public health response, almost $25 million from lost productivity, and more than $1.8 million from direct medical expenses, according to the tool. For 2025, the tool estimates the 2289 confirmed cases carried a cost of more than $37 million. Texas, the epicenter of the largest outbreak last year, accounted for nearly $13 million of that across 803 cases, including $9 million in public health spending, $4 million in lost productivity, and about $288,000 in direct medical costs.

The tool draws on more recent, state-specific cost and financing data than an earlier study from the same researchers. That study reviewed published studies and government reports across 18 states and estimated that launching an outbreak response costs about $298,000 in fixed costs, plus about $16,300 for each additional case. The earlier model excluded productivity losses.

Costs Extend to Contacts Who Never Get Sick

A 2025 study by Joey Mattingly, a pharmacist and health economist at the University of Utah, modeled a hypothetical 1500-case outbreak and estimated it could cost about $90 million, including roughly $26 million in productivity losses. Each quarantined person may represent about $300 in lost productivity, meaning a single case that exposes 40 to 50 people could generate $12,000 to $15,000 in losses even if none of those contacts become infected. Mattingly argues that these ripple effects can quickly outweigh the investment needed to vaccinate people against measles.

People exposed to measles who cannot produce proof of vaccination may face a blood test or a 21-day quarantine, David Margolius, MD, director of public health for Cleveland, Ohio, and director-at-large of the Big Cities Health Coalition, told The Guardian.³ Two doses of the measles, mumps, and rubella (MMR) vaccine are 97% effective.

PAHO Reviews US Elimination Status

The US, which has held measles elimination status since 2000, could lose it in the coming days. Experts convened by the Pan American Health Organization (PAHO) are assessing whether US measles transmission has continued uninterrupted for 12 months or longer, based on epidemiological and laboratory evidence, Reuters reported.⁴ PAHO Director Jarbas Barbosa will make the final decision, which is expected to be made public early next week. Canada, Spain, and the UK recently lost their measles elimination status; the US has withdrawn from the WHO but remains a member of PAHO.

CDC Director Erica Schwartz, MD, said the agency's response would not fundamentally change if the status is lost and that it would continue to emphasize the MMR vaccine as the primary way to prevent measles. HHS said in a statement that national vaccination rates had declined before Health and Human Services Secretary Robert F. Kennedy Jr took office.

Kennedy has been criticized for meddling in vaccine policy, The Guardian reported.³ Paul Offit, MD, director of the Vaccine Education Center at Children's Hospital of Philadelphia, told the outlet that measles is now endemic in the US regardless of PAHO's decision because the share of vaccinated people has dropped sharply. Margolius said cases are climbing nationwide and could do so even under an administration more supportive of public health, adding that the trend will continue until the US rejoins the WHO and cooperates with health agencies worldwide.
