Hidalgo County detention center reports New Mexico’s first measles case of 2026
A detainee at the Hidalgo County Detention Center in Lordsburg tested positive Feb. 25, putting jail staff, visitors and transport crews on alert as measles spread.

Hidalgo County’s detention center became the site of New Mexico’s first confirmed measles case of 2026 after a detainee in Lordsburg tested positive on Feb. 25.
Measles usually starts with fever, cough, a runny nose and watery eyes before the rash appears. Public health workers traced who had been inside the facility and whether they were protected by the MMR vaccine. Anyone uncertain about past immunizations was urged to check their records, especially if they had worked in the jail, brought inmates to court or visited a detainee.
The New Mexico Department of Health posted a notice that measles had been detected in the Hidalgo County Detention Center. By March 3, state officials were investigating the Doña Ana County Detention Center and other southern New Mexico detention facilities after four federal inmates tested positive. By March 6, a sixth measles case had been confirmed in a New Mexico jail, and later state tallies put the 2026 count at 13 cases tied to three county detention centers: Luna County Detention Center with eight, Doña Ana County Detention Center with three and Hidalgo County Detention Center with two.

The case landed in a rural border county with limited health-care capacity. Officials did not publicly list exposure sites outside the detention system, and they did not identify the inmate or describe the person’s condition, but the investigation still stretched across the daily traffic of jail operations. That included anyone who handled inmates, moved paperwork through the courts, or came and went from the facility for work or family visits.
Anyone who had been in the detention center around the Feb. 25 diagnosis and then developed fever, cough, runny nose, watery eyes or a rash was urged to seek medical help before arriving in person so clinics could protect other patients. People who needed records could start with their health care provider for MMR documentation and contact the detention center about any exposure notices tied to their time inside.
