The Centers for Disease Control and Prevention said the polio virus was detected in wastewater samples collected in June 2022 from Rockland County outside New York City. An unvaccinated adult recently contracted the life-threatening disease, but health officials said Tuesday, Aug. 2, 2022, they have not identified additional cases. (AP Photo, File)
