Why it matters
The ministry issued an Epidemiological Alert No. 008-2026, warning that heavy rain, flooding, and unsafe water could spread disease. El Niño, which involves warming Pacific Ocean waters, brings heat and heavy rain to Peru’s coast.
Locally acquired Dengue cases are being reported, transmitted through infected Aedes mosquitoes, with the disease range expanding due to climate change.
