The Hawaiʻi Department of Health has been notified of a second detection of measles virus in wastewater from West Maui County. The latest positive sample was collected Nov. 30, 2025 and was tested through the National Wastewater Surveillance System.

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.

Health officials are investigating a possible new measles case on Maui, but say there are no “confirmed” cases so far for 2015. Ronald Balajadia, Immunization Branch Chief for the Department of Health tells Maui Now that the report is currently under investigation.

A mobile measles treatment area has been set up outside of the Kaiser Maui Lani Clinic in Wailuku as a precautionary measure to prevent additional exposure, officials tell Maui Now.

The state Department of Health has confirmed four additional cases of measles on Maui and Kauaʻi, bringing the total number of confirmed measles cases in these two separate clusters in Hawaiʻi to seven, and the total reported cases for the year to nine.

The Hawaiʻi State Department of Health has confirmed three cases of measles in the state, one on Maui and two on Kauaʻi. Hawaiʻi now has a total of five confirmed cases reported in the state this year, according to state health officials.

Department officials released information this afternoon saying the child is hospitalized and recovering, but was infectious while traveling back to Honolulu and during visits to healthcare providers.
