West Nile Virus Reported In Cape Cod Mosquito Sampling

FALMOUTH, MA — Another case of West Nile Virus has been detected in a mosquito sampling taken from Falmouth.

On July 29, the Massachusetts Department of Public Health reported that a sample collected on that day included a positive test. The sample was taken from a location in the area of Siders Pond.

The Cape Cod Mosquito Control Project collects routine mosquito samples as part of MDPH’s surveillance program for mosquito-borne diseases, officials said.

The last positive WNV mosquito sample detected in Falmouth was June 24, 2025, off Woods Hole Road. No human cases have been detected.

"The Falmouth Health Department will continue to work closely with the MDPH and the Cape Cod Mosquito Control Project (CCMCP) on mosquito control efforts," officials said. "The location of the positive sample is routinely treated by the CCMCP and will continue to be an area of focus throughout the mosquito season."
