Campo Grande health officials warn of measles risk due to low vaccination
Health authorities in Campo Grande, Brazil, are raising concerns regarding the risk of measles reintroduction following a decline in vaccination rates. While the city has not recorded a confirmed case since 2020, the current coverage for the Triple Viral vaccine among children stands at 78.53%, significantly below the 95% target recommended for population protection.
The alert comes amid increased measles circulation across the Americas. As of October 3, 2026, 55,792 cases and 77 deaths have been reported across 17 countries and territories in the region. The U.S. Centers for Disease Control and Prevention (CDC) noted this represents the highest annual case count in over 35 years. Guatemala, Mexico, Peru, and Canada account for over 95% of these regional cases.
In Brazil, 52 imported cases were recorded by October 5, 2026, distributed across São Paulo (41), Amazonas (10), and Rio de Janeiro (1). Veruska Lahdo, superintendent of Health Surveillance at Sesau, emphasized that reaching the 95% vaccination goal is essential to prevent the virus from spreading in the municipality.
