Overview
- The Health Ministry’s campaign, which runs March 23–27, mobilizes all 32 states to curb dengue and chikungunya.
- Authorities are prioritizing 420 high‑risk localities and Mexico City’s 16 health jurisdictions, with operations in 1,210 primary clinics, 252 hospitals, schools, tourist zones and other crowded sites, including World Cup host states.
- The Patio Limpio strategy calls for mass junk removal and sanitary inspections to clear standing water containers, with an official goal of eliminating all breeding sites in priority areas.
- Areas without active cases will rely on ovitrap surveillance, which uses egg‑collecting traps to spot Aedes aegypti and guide targeted steps such as larval treatments, fumigation and thermal fogging.
- The plan adds a phased Wolbachia mosquito replacement to lower virus transmission without more insecticide use, and officials will lean on World Cup outreach to engage residents and visitors.
