Sewage Signals Measles Surge Days Early
16 Jan
Summary
- Wastewater testing can predict measles outbreaks weeks before clinical confirmation.
- A proposed funding cut threatens the national wastewater surveillance system.
- Colorado and Oregon studies highlight early detection capabilities.
Wastewater surveillance offers a critical early warning system for measles outbreaks, detecting the virus days to months before clinical cases are identified. Researchers in Colorado and Oregon published findings demonstrating how sewer system monitoring can alert public health officials to burgeoning infections. This approach has proven valuable for tracking various diseases, including COVID-19 and polio.
Despite its success, the national wastewater surveillance system, managed by the CDC, is under threat from proposed budget cuts. Funding could decrease dramatically, forcing difficult prioritization of essential activities. This reduction poses a risk to a system currently monitoring over 1,300 treatment sites serving millions nationwide and supporting state-level innovation.
States are preparing for potential federal funding losses, as most wastewater surveillance programs are federally funded. The Colorado program, for instance, relies entirely on federal support. The potential cuts raise concerns about sustaining these vital monitoring efforts, particularly for states that may not have developed robust independent programs.
