Puno Measles Outbreak Rises to 42 Cases as Peru Tightens Bolivia Border Checks

Low vaccine coverage has left gaps that raise the risk of spread to Lima.

Overview

  • The regional health office reports 42 confirmed infections in Puno, concentrated in Juliaca (San Román) and Sandia, with single cases in Carabaya and Puno city.
  • Health officials confirm community spread and point to heavy cross‑border travel with Bolivia and recent carnival gatherings as likely drivers.
  • Peru’s migration agency has created new checkpoints on the Bolivia border in Puno to screen travelers and reinforce containment.
  • The Health Ministry has sent rapid‑response teams to run door‑to‑door vaccination and contact tracing, with more than 200 brigades and thousands of home visits despite some refusals.
  • Lima has 23 suspected cases under review, and falling second‑dose coverage near 71% in 2025 raises spread risk as Mexico reports more than 15,000 cases in its ongoing outbreak.
