Infant Protection From Measles Might Wane Sooner Than Expected

A retrospective analysis presented at IDWeek 2026 this month in Washington, D.C., suggests that infants’ maternal protection against measles may decline much earlier than previously believed, leaving many babies susceptible to infection months before their first measles, mumps, and rubella (MMR) vaccination, which is recommended at age 12–15 months. As reported in meeting coverage from MedPage Today, researchers analyzed measles antibody levels in maternal-infant pairs and found that although infants had higher neutralizing antibody concentrations …

New York Declares Emergency To Address Rising Measles Cases

Because of rising measles cases, New York’s governor this week declared a State Disaster Emergency, which will remain in effect through November 4, 2026, according to a press release. This is a public-health response measure designed to expand vaccination, testing, surveillance, and outbreak-control capacity. The action specifically extends the pool of eligible individuals who can administer measles-mumps-rubella vaccines and allows nurses to order testing rather than requiring the order to come from a physician or …

Immune Amnesia From Measles Can Last For 5 Years

For a patient with a measles infection, the health effects can last well beyond the acute illness. The measles virus destroys memory B and T cells that help the immune system recognize previously encountered pathogens, producing “immune amnesia,” according to an analysis in CIDRAP. As a result, patients can lose protection acquired through prior infections or vaccination and become susceptible again to bacterial and viral illnesses. Studies suggest measles survivors may lose 11%–73% of their …

What Is Congenital Measles?

The American Academy of Pediatrics (AAP) released a new document that provides guidance on congenital measles, including its definition, clinical presentation, evaluation and management, infection control, long-term follow-up, and prevention. Organized with frequently asked questions, the document was developed in response to ongoing measles outbreaks and the potential for congenital measles cases in the United States, according to AAP. The clinical information is important because presentations of congenital measles infection are highly variable, ranging from …

Measles Outbreak On Pace To Surpass Last Year’s High Case Counts

Americas Region Loses Measles Elimination Status

This week, Canada lost its measles elimination status, and as a result, the “Americas” region overall no longer has its verified elimination status as designated by the Pan American Health Organization (PAHO). The Americas first gained measles-free status in 2016, lost it 2 years later, and then re-established the elimination status in 2024. As of November 7, 2025, reports show 12,596 confirmed measles cases in 10 of the region’s countries with 28 deaths (23 in …

Measles Surge Isn’t Behind Us Just Yet

As of October 8, 2025, there have been a total of 1,563 confirmed measles cases reported in 42 states this year, according to the Centers for Disease Control and Prevention. The largest proportion of cases are among those ages 5-19 years (39%), and 92% of all cases are among unvaccinated people or those with unknown vaccine status. However, experts speaking to NPR believe the numbers are actually much higher than what has been reported and …

Measles Cases Keep Climbing, Exceeding Long-Term Records

This month, the United States reached a level of more confirmed measles cases for the year than in any time in the past 30 years. 1990 saw an unusual high of 27,808 measles cases reported with a series of outbreaks in large metro areas. However, subsequent improvement in vaccine policies encouraged higher vaccination rates, which helped dramatically reduce cases over the next few years. Cases dropped to 2,126 by 1992, and measles was declared eliminated …

Some Measles Cases Are Showing Up In Vaccinated Patients

Among the 1,197 confirmed measles cases in the United States so far this year, about 3% have occurred in people who received 2 doses of the measles, mumps, rubella (MMR) vaccine and 2% in those who received 1 dose, according to an update from the Centers for Disease Control and Prevention (CDC).
