Mass. health officials announce additional human cases of West Nile virus

Massachusetts health officials reported two new human cases of West Nile virus, raising the total to eight this season. The cases involve a woman in her 60s from Middlesex County and a man in his 50s from Suffolk County, prompting an elevation of the risk level to high in several communities. Public Health Commissioner Robbie Goldstein noted that 80 percent of cases in the past decade occurred in August or September, urging residents to continue protective measures. Most infected individuals do not display symptoms, though severe illness can occur. This season has seen 445 mosquito samples testing positive for the virus, alongside a reported case in a goat.

Officials also detected Eastern equine encephalitis (EEE) in mosquito samples, though no human or animal cases have been reported. To mitigate risks, health officials recommend using EPA-registered insect repellents and avoiding outdoor activities during peak mosquito hours.
