Study confirms measles wastewater testing provided early warning during New Mexico’s outbreak

New Mexico wastewater testing for measles last year forewarned public health experts of the spread to a new county five days before cases were clinically confirmed during the state’s outbreak, according to a new study. Authors say the findings are important because measles, a highly contagious airborne virus, continues to spread across the country, with the U.S. experiencing its largest measles outbreak in decades.
