Overview
- Peru’s Health Ministry reported 27 confirmed measles cases in Puno with 38 more under laboratory review and confirmed local person‑to‑person spread.
- The cases cluster in San Pedro de Putina Punco and Juliaca with one in Carabaya, and officials noted cross‑border migration with Bolivia as a possible factor under joint coordination.
- Response teams set up ring vaccination, traced contacts, and went door to door at about 8,000 homes, yet more than 1,500 people refused vaccination.
- Officials said second‑dose coverage fell in 2024 and 2025 and sits near 15% to 17% so far in 2026, which leaves more people at risk of infection.
- Neighboring regions raised health alerts to strengthen surveillance, and Mexico City said its larger outbreak is controlled after 3.9 million doses and will ask World Cup visitors to arrive vaccinated.
