New Mexico health officials said five inmates at the Luna County Detention Center in Deming have tested positive for measles, marking the first known cluster in a state correctional facility during this year’s outbreak. The centre, which holds roughly 400 people and employs 100 staff, has quarantined the infected individuals, suspended in-person visits and shifted court hearings to virtual formats while vaccination histories are verified and additional testing kits are deployed.
The new cases raise the state’s 2025 tally to 86, according to the Department of Health. New Mexico’s outbreak began in February and has included one fatality, an unvaccinated adult who died in March. Nationally, the U.S. has recorded 1,227 measles cases so far this year across 12 states.
Officials urged residents, particularly in Luna County, to ensure they are fully immunised. Demand for the measles, mumps and rubella vaccine has surged in New Mexico, with more than 37,500 doses administered since February compared with about 19,300 in the same period last year. The two-dose regimen is 97% effective at preventing infection.
