KAUAI, Hawaii (KITV) — The Hawaii Department of Health (DOH) reported that a wastewater sample from Kauai County tested positive for the measles virus. The sample, collected on February 25, 2026, in East Kauai County, was confirmed on Monday, March 16, 2026.
This detection comes after a confirmed measles case was reported in Hawaii on March 7, 2026. The case involved a visitor from the continental U.S. who was on Oahu and Hawaii Island between February 26 and March 4. However, this case doesn’t align with the Kauai wastewater detection date.
Measles symptoms include a high fever, cough, runny nose, and red eyes, followed by a rash starting at the head. Serious complications can rise, making vaccination crucial. The DOH urges residents to stay up to date with the measles, mumps and rubella (MMR) vaccine, especially infants under 1 year who are at a higher risk.
Wastewater testing is part of routine infectious disease surveillance in Hawaii. It can detect viral genetic material, serving as an early indicator of potential cases. The National Wastewater Surveillance System and WastewaterSCAN are also monitoring measles in other Hawaii counties.
