New York declares disaster emergency after polio detected in several counties

The governor's latest step is a way to boost low vaccination rates in areas where the virus has been found

New York's governor, Kathy Hochul, declared a disaster emergency on Friday and said the state was stepping up its polio-fighting efforts after the virus was detected in the wastewater of yet another county in the New York City area.

Health officials began checking for signs of the virus in sewage water after the first case of polio in the US in nearly a decade was identified in July in Rockland county, close to the city.
