Measles outbreaks surge in Yucatan Peninsula and Peru
Measles outbreaks are causing significant concern in Peru and Mexico. In Peru, the Red de Salud Carabaya has intensified vaccination efforts following the death of a 16-year-old in Mariscal Ramón Castilla who had not received the required vaccine doses. Health authorities in the Puno region are aiming for a 95% coverage rate to achieve herd immunity, though current progress in Carabaya stands between 55% and 60%. In the Loreto region, medical specialists emphasize the urgency of reaching isolated communities to prevent transmission.
Simultaneously, the Yucatan Peninsula in Mexico has seen a massive surge in measles cases. Reported figures show an approximate 1,940% increase, rising from 22 cases in 2025 to 449 in 2026. Quintana Roo has been the hardest hit with 389 cases, followed by Yucatán and Campeche. Experts attribute this resurgence to gaps in vaccination coverage and high population mobility in tourist areas.
