Overview
- National surveillance shows 89,353 cumulative dengue cases and 101 deaths by epidemiological week 43, a year‑on‑year rise of 172% in cases and 94% in deaths compared with 2025.
- Regional hotspots continue to drive the surge with the Sullana subregion reporting 7,390 cases through week 44 and Lima Sur accumulating about 1,200 cases, including more than 300 in San Juan de Miraflores where vaccination was prioritized.
- Health systems are strained as primary clinics refer severe patients to higher‑level hospitals, an Áncash (Casma) dengue death is under administrative review after family allegations of premature discharge, and hospitals report increased urgent transfers to Chimbote.
- Leptospirosis is rising in parallel, with Minsa reporting a 109% increase versus 2025 for more than 15,500 infections, 1,614 hospitalizations and 54 deaths, which adds to clinical and logistic pressures in affected districts.
- Authorities have stepped up house‑to‑house fumigation, larval control and public 'lava, tapa, voltea y tira' campaigns and health officials warn that continued El Niño rains and damaged infrastructure such as the Salitral bridge could worsen access to care and raise case counts further.
