Peru Faces Large Dengue Surge as Deaths Rise

El Niño-driven warmer weather with heavier rain is increasing mosquito breeding, raising the risk of more dengue cases.

Overview

  • National health data show 76,784 reported dengue cases and 81 deaths so far in 2026, a marked rise in lethality compared with the same period in 2025.
  • Lambayeque and La Libertad are current hotspots with roughly 10,559 and 10,449 cases respectively, and Trujillo province alone accounts for about 5,807 cases in La Libertad.
  • La Libertad health authorities launched targeted vaccination drives using the single-dose Qdenga (TAK-003) for people aged about 10 to 20, with 7,000 doses authorized by the Ministry of Health for local campaigns.
  • Staff at Ferreñafe’s public hospital have warned that cases treated in private clinics may not be included in official tallies, a claim that could mean the true caseload is higher than reported.
  • Children and adolescents make up a large share of recent deaths and severe cases, delayed care and self-medication are common, and officials urge early medical attention plus household elimination of standing water to reduce mosquito breeding.
