Baja California Sur’s health sector has administered more than 63,000 measles vaccines so far in 2026, as the state monitors nine active cases under epidemiological surveillance. State Health Secretary Ana Luisa Guluarte Castro announced the figures as part of an intensified campaign targeting residents aged six months to 49 years across all five municipalities.
Six of Nine Active Cases Tracked in Cabo San Lucas
Six of the nine cases currently under surveillance are concentrated in Cabo San Lucas, the state’s busiest tourist corridor. The remaining three cases are spread across other parts of the state. Guluarte Castro said the concentration in Los Cabos prompted authorities to strengthen prevention efforts in that municipality.
The campaign places special emphasis on infants aged six to 11 months, who receive what health officials call a “zero dose” vaccine. This early dose provides initial protection before the standard childhood immunization schedule begins. Vaccines are available free of charge at public health facilities statewide.
BCS Fares Better Than Most Mexican States
Baja California Sur’s situation stands in contrast to the national picture. Mexico has recorded more than 7,400 confirmed measles cases in 2026 alone, with over 30 measles-related deaths nationwide. Jalisco leads the country with 17.85 confirmed cases per 100,000 people. As of mid-February 2026, BCS was one of just five states that had not recorded a single confirmed case this year, though probable cases had been detected.
Nationally, Mexico’s Health Ministry (SSA) reported administering over 30.1 million measles vaccine doses between January 2025 and mid-March 2026. The federal campaign prioritizes children aged six months to 12 years and targets unvaccinated individuals up to age 49 in selected states.
Where to Get Vaccinated in BCS
Free measles vaccines are available at public health centers in all five BCS municipalities: La Paz, Los Cabos, Comondú, Loreto, and Mulegé. No Mexican citizenship is required. Measles is highly contagious and can cause severe complications including pneumonia and encephalitis, particularly in young children and unvaccinated adults.
Health authorities plan to continue the vaccination push through the coming months, with particular focus on Los Cabos given the active case cluster there, according to the Baja California Sur state government.
