Wastewater testing has found polioviruses genetically tied to a case that left an unvaccinated Rockland County, N.Y., resident paralyzed this summer in at least five of the state's counties, according to a new CDC report.
The report, published Oct. 28, is based on wastewater testing from samples collected from March 9 through Oct. 11 from 28 sewersheds serving parts of Rockland County and 12 other counties. Eighty-nine samples, or 8.3 percent of 1,076 samples collected, tested positive for poliovirus type 2. Of those, 82 were linked to the virus isolated from the Rockland County patient who was left paralyzed
"Although most persons in the United States are sufficiently immunized, unvaccinated or undervaccinated persons living or working in Kings, Orange, Queens, Rockland, or Sullivan counties, New York should complete the polio vaccination series to prevent additional paralytic cases and curtail transmission," the CDC report said.
CDC officials recently told CNBC they are considering the use of a novel oral polio vaccine not used in 20 years to halt the outbreak.
