Leishmaniasis cases surge by 399% in Mexico's Yucatan Peninsula

Leishmaniasis cases in the Yucatan Peninsula have increased by nearly 400% compared to the same period last year. According to the Federal Government's Secretariat of Health Epidemiological Surveillance Bulletin, the region recorded 439 patients in 2026, up from 88 cases during the same timeframe in 2025.

Quintana Roo accounts for the vast majority of these infections, with 342 cases representing approximately 77.9% of the total in the peninsula. This marks a 434.4% increase for the state specifically. Campeche follows with 64 accumulated cases, compared to nine cases in the previous year. The rise in this parasitic disease poses a significant challenge for epidemiological surveillance, particularly in rural communities and areas with frequent contact with jungle environments.
