More than 2,000 measles cases have been reported nationwide in 2026, according to NBC News. Virginia has confirmed 79 cases, including 72 tied to an outbreak in central Virginia, while Florida has reported 25 cases and Pennsylvania has identified 16 cases linked to an Erie County outbreak. Texas remains the hardest-hit state with more than 750 cases, followed by New Mexico with more than 80 cases.
For clinical laboratory professionals, the outbreaks highlight the ongoing importance of rapid identification, confirmatory testing, and public health reporting. Measles remains one of the most contagious infectious diseases, and laboratory confirmation plays a critical role in outbreak investigations and contact tracing efforts.
The Centers for Disease Control and Prevention (CDC) notes that measles is preventable through vaccination, yet outbreaks continue to occur in communities with lower immunization rates. Public health officials have repeatedly emphasized that two doses of the measles, mumps, and rubella (MMR) vaccine provide strong protection against infection.
Chris Thomson, MD, MS, MBA, FACEP, executive vice president for Centra Health, told NBC News that early intervention can keep individuals out of the hospital. He said, “By being able to get to someone who calls at an early stage of their illness, and perhaps being able to go to a home and provide IV fluids to someone who’s dehydrated keeps them from becoming ill enough [to warrant a hospitalization]. Also by being in the home, we’re able to identify whether or not there are others who are ill, providing more surveillance than we would if we did not have this service.”
Growing concerns about national trends
A recent article from Dark Daily’s sibling publication, Today’s Clinical Lab, noted that as millions of fans travel across the United States, Canada, and Mexico for the 2026 FIFA World Cup, clinical laboratories may face increased demands for infectious disease surveillance, testing, and outbreak response.
The article explained that large international sporting events can facilitate the spread of highly transmissible diseases, particularly measles, as well as influenza, COVID-19, RSV, dengue, mpox, and other emerging pathogens. Laboratory professionals are expected to play a critical role in early detection through diagnostic testing, genomic sequencing, wastewater surveillance, and public health reporting.
The author, Rodney E. Rohde, PhD, MS, SM(ASCP)CM, SVCM, MBCM, FACSc, emphasized that strong laboratory preparedness, vaccination efforts, and coordinated surveillance systems will be essential to identifying and containing potential outbreaks during the tournament.
The increase in cases comes as the US faces the possibility of losing its measles elimination status, a designation it has maintained since 2000. Health experts have attributed much of the recent resurgence to declining vaccination rates and expanding pockets of susceptible individuals.
For laboratories, the expanding outbreaks serve as a reminder that diseases once considered largely controlled in the US can quickly reemerge, placing renewed demands on testing capacity, disease surveillance systems, and public health response infrastructure.
