US Measles Resurgence Threatens Public Health

Measles has re-emerged as a significant public health concern in the United States, with continuous circulation for over a year and a record number of cases in 2025 and 2026. This resurgence is attributed to falling vaccination rates, which have dropped below the 95% threshold needed for herd immunity in many regions. The United States, along with Mexico, is at risk of losing its measles elimination status, a designation achieved in 2000. The economic costs of containing these outbreaks are substantial, with a single outbreak costing millions of dollars. Beyond measles, the declining public trust in institutions like the United States===Centers for Disease Control and Prevention and the general decline in vaccine coverage indicate a systemic problem in the United States' capacity to manage infectious diseases, posing a long-term threat to public health and economic stability.
