ALBANY — New York declared a state of emergency on Friday to boost vaccinations against polio. Gov. Hochul issued an executive order expanding the state’s network of vaccine administrators to EMS workers, midwives and pharmacists as evidence mounts that the once rare virus is spreading in the state. Only one case of paralytic polio has been recorded in Rockland County so far, but wastewater samples from across the city and surrounding suburbs suggests the pathogen is circulating across the region.
