#measles positive

The Hawaiʻi Department of Health is monitoring a positive wastewater sample for the measles virus, the first-ever wastewater detection of the virus for Maui County. The samples were collected Nov. 18, 2025, at two sites in Central and West Maui County, and tested through the National Wastewater Surveillance System. The virus detected is the naturally occurring type that spreads from person to person, not the weakened form used in vaccines. No suspected measles cases have been identified on Maui.
