Regional measles, pertussis & dengue outbreaks continue

Overview

Honduras’ pertussis epidemic has accelerated, with confirmed cases climbing to about 190 by mid‑2026 and infant deaths rising to 15. Measles activity in Honduras has shifted to sustained local transmission, with sixteen cases recorded by early July. In Mexico, measles outbreaks persist, prompting vaccination drives in Zacatecas.

Dengue transmission is intensifying across the region. In Peru, the Ministry of Health has reported 81 deaths related to the disease so far in 2026, a 59% increase compared to 2025. High temperatures associated with the El Niño phenomenon are driving this surge, particularly in the Peruvian Amazon and regions bordering Ecuador. In the Huánuco region, cases reached 953 as of October 10, a 123% increase over the previous year. In response, Health Minister Luis Dyer launched the ‘Batallón contra el dengue’ (Dengue Battalion) in Piura. By late October, the Piura region reported over 14,000 cases and 13 deaths. Consequently, health officials are planning an intensive vaccination campaign for those aged 10 to 20 starting October 12, while specialists propose expanding the vaccination age range to include children as young as 6 years old. Due to the climate-driven surge, the Peruvian government has issued an epidemiological alert, warning of potential increases in diseases such as malaria and leptospirosis.

Other regional impacts include 5,302 confirmed cases in Costa Rica, a 38.6% increase over 2025, primarily in Alajuela. In Panama, cases reached 9,055 with 19 deaths. In Argentina, health authorities in Tucumán are intensifying prevention efforts against dengue and chikungunya, conducting house-to-house inspections in neighborhoods like Villa Alem to eliminate Aedes aegypti breeding sites. Mexico continues prevention efforts in the Adolfo López Mateos area to remove stagnant water containers.
