Measles Detected in Wastewater: A Sign of Declining Vaccination Rates
Measles cases in the U.S. are rising due to declining vaccination rates, with 14 outbreaks reported in 2025—a significant increase from the previous year. Researchers are now utilizing wastewater surveillance to detect the measles virus nationwide, offering an earlier warning system than traditional methods. This approach, which has already detected measles in three locations, identifies the virus in sewage before symptoms appear in individuals, allowing for faster public health responses. Ultimately, this early detection can help target vaccination efforts and better manage outbreaks.
