Overview
- The Health Ministry issued Epidemiological Alert AE-CDC No. 001-2026 after sustained increases over six epidemiological weeks in selected districts across Amazonas, Huánuco, Junín, Loreto, Madre de Dios, San Martín, Tumbes, Piura, Ucayali and La Libertad.
- The alert orders immediate strengthening of case reporting via SiEpi, activation of rapid-response teams, daily situational updates, entomological surveillance, vector control and the use of Dengue App and Prom App.
- In Piura, rising notifications are concentrated in Sullana, Catacaos, Veintiséis de Octubre, Paita and Tambogrande, where specialists warn that scarce laboratory supplies are limiting confirmation of suspected infections.
- Ayacucho reports a 92% drop in cases from 2024 to 2025 and no positives so far in 2026, reflecting localized gains from targeted interventions.
- CDC forecasts suggest roughly 34,613 dengue cases could occur across 20 departments by March 2026, indicating continued risk during the rainy season.
