Peru Declares Puno Measles Alert as Mexico Reports Fewer New Cases After Mass Vaccination

The new cases in southern Peru signal ongoing regional spread despite Mexico’s recent downturn.

Overview

  • Health officials in Peru’s Puno region, who declared a sanitary alert Friday, confirmed two measles cases and began house-to-house checks and contact tracing.
  • The cases involve a 20-year-old woman and a 4-year-old from San Pedro de Putina Punco, with the child unvaccinated and both diagnoses confirmed by Peru’s national lab.
  • Mexico has recorded about 14,869 confirmed cases and 36 deaths since early 2025, with infections reported across 458 municipalities in all 32 states.
  • Mexico’s Health Ministry says reported cases have fallen over the past four weeks after a nationwide push that delivered about 17.2 million vaccine doses.
  • Baja California reports 49 cumulative cases with 10 active, no deaths, and no identified community transmission, reflecting tighter local control in that border state.
