The Centers for Disease Control and Prevention confirmed this month that 2026 has become the worst year for measles in the United States in 35 years. The Centers for Disease Control and Prevention has now officially recorded more measles cases this year than in all of 2025, making 2026 the worst for measles in 35 years. With more than five months remaining in the year, case counts are still climbing, and at least 2,318 cases have been reported with more than five months left in the year.
Why This Matters Beyond Pediatrics
Measles is often framed as a pediatric or primary-care issue, but its extreme contagiousness makes it relevant to every clinical setting where patients congregate in waiting rooms, including dental and oral surgery practices. According to the CDC, if one person has measles, up to nine out of 10 people nearby will become infected if they are not protected. That level of transmissibility means front-desk and clinical staff across all specialties should be prepared to recognize symptoms and respond appropriately.
The demographic data adds urgency for practices treating families and young patients. Those aged 5 to 19 account for 51% of all confirmed cases, while children under five represent 20% and face elevated hospitalization risk: 10% of infected children under five have required hospitalization. The underlying driver is a well-documented decline in immunization coverage. A critical driver of the ongoing crisis is the erosion of MMR vaccination coverage among kindergartners, with national coverage declining from 95.2% during the 2019–2020 school year to 92.5% in 2024–2025, falling below the 95% threshold required for community immunity.
Practical Steps for Clinical Settings
Given that the majority of infected people — 93%, according to the CDC — are unvaccinated, practices in or near affected jurisdictions may want to revisit a few basics:
- Pre-visit screening: Ask about recent rash, fever, or known measles exposure before patients enter the waiting area, especially in regions with active outbreaks.
- Airborne precautions awareness: Unlike most respiratory pathogens managed with standard surgical masks, measles is airborne and requires N95 or higher-level respiratory protection for staff in a suspected exposure.
- Isolation protocol review: Confirm your team knows how to promptly isolate a suspected case and notify local public health authorities.
- Staff immunization records: Verify MMR immunity status for all clinical staff, particularly in offices treating pediatric or immunocompromised patients.
Federal outbreak response has been described by public health experts as limited relative to the scale of the surge. The federal health response to ongoing measles outbreaks, however, has been minimal, and the CDC has been without a permanent director for the majority of President Donald Trump's second term. That means individual practices and local health departments are carrying more of the burden for surveillance and response than in past years.
Authorities are also watching a broader milestone: whether the U.S. retains its measles elimination status, a designation held since 2000. Authorities will examine the U.S. measles status in November. Regardless of that outcome, the current surge is a reminder that airborne precaution readiness — not just standard droplet and contact precautions — deserves a place in every practice's infection control plan this year.
