Overview
- Peru's health agency reported 46,669 dengue cases and 57 deaths through epidemiological week 33, reflecting a fast national increase concentrated in coastal and Amazonian regions.
- Piura is a regional hotspot with 8,272 cases and five deaths so far in 2026, and provincial health officials say warning‑sign and severe cases have climbed sharply compared with 2025.
- The Ministry of Health bought 444,780 vaccine doses and is running free two‑dose campaigns focused on people aged about 10–20, health workers and exposed military, with doses spaced three months apart.
- States and regions have expanded door‑to‑door larval control brigades and targeted fumigations but experts warn that fumigation alone does not remove eggs that can survive months on container walls so household cleaning is essential.
- Officials cite El Niño rainfall and higher temperatures as drivers that can shorten mosquito development and widen breeding sites, increasing the chance of larger outbreaks similar to the large 2023–2024 epidemics.
