Measles

• Public health experts warn that the U.S. has effectively lost its measles elimination status, as only 6% of 2026 cases are now linked to travel compared to a historical average of 40%. • In other health news, the FDA approved bulevirtide on May 22, 2026, marking the first-ever approved treatment for Hepatitis Delta. • On June 17, the federal government announced $223.1 million in new funding for CCBHC community mental health clinics to improve care access and reduce emergency room visits.

• The CDC is ending its federal measles diagnostic testing program, shifting the responsibility for these tests to state laboratories. • While state labs already handle the majority of measles testing, critics are alarmed that the loss of federal oversight could impact surveillance and response times. • This policy shift reflects a transition toward decentralized public health monitoring, though concerns remain regarding the consistency of testing capabilities across different states.

• Opinion writers for KFF Health News address critical public health concerns, including the loss of the United States' measles-eliminated status and the safety of sunscreen. • One contributor argues that the U.S. can no longer claim to have eliminated measles due to recent outbreaks and declining vaccination rates. • The collection also features a political perspective questioning the security of the pharmaceutical supply chain and the influence of Chinese Communist Party-controlled companies on prescription refills.

• A CIDRAP op-ed argues that the United States has officially lost its status as a measles-eliminated country, asserting that current outbreaks represent continuous internal spread rather than isolated reintroductions. • The author criticizes the use of cautious phrasing by health officials, noting that the evidence from the virus itself confirms a failure to maintain elimination. • This shift is critical because it signals a breakdown in public health defenses, highlighted by a staggering 26% case-fatality rate in a recent outbreak.

• Two new reports, including one from the CDC's Morbidity and Mortality Weekly Report, analyze the difficulties in containing recent measles outbreaks within the U.S. • The studies focus on a major outbreak that began on October 2, 2025, in Spartanburg County, South Carolina, marking the largest U.S. outbreak since the disease was declared eliminated in 2000. • Researchers identified complex social and cultural barriers that hinder essential public health efforts, specifically vaccination, testing, and education.

• As of June 18, 2026, a measles outbreak in the U.S. has reached 2,104 confirmed cases across 41 different jurisdictions. • The CDC has issued a warning that increased summer travel may accelerate the spread of the virus, posing a significant risk to families. • This surge highlights a critical public health challenge as officials urge vaccination and awareness to contain the outbreak.

• Declining vaccination rates have led to a resurgence of measles, prompting biotech companies and researchers to seek pharmaceutical treatments for the disease. • Dr. Plemper of Georgia State University is working on a drug that could potentially be used off-label to treat measles patients if approved. • Experts, including Dr. Mina, emphasize that while new treatments are necessary to prevent deaths, widespread vaccination remains the only effective way to stop the outbreaks.
