What to Know
- New York state Health Commissioner Mary Bassett warned that the confirmed polio case in an unvaccinated adult and the detection of the virus in sewage could indicate a larger outbreak is underway
- "Based on earlier polio outbreaks, New Yorkers should know that for every one case of paralytic polio observed, there may be hundreds of other people infected," Bassett said
- State health officials are urgently calling for people who are unvaccinated to receive their shots as soon as possible
A federal team has been deployed to New York to investigate the state's one positive case of polio — found in an unvaccinated adult in Rockland County who suffered paralysis.
The CDC confirmed its presence in the Empire State as health officials issued an urgent call for the unvaccinated to get inoculated against the virus, citing new evidence of possible "community spread."
"CDC continues to collaborate with the New York State Department of Health to investigate their recent polio case, including ongoing testing of wastewater samples to monitor for poliovirus and deploying a small team to New York to assist on the ground with the investigation and vaccination efforts," a spokesperson confirmed Sunday.

The polio virus has now been found in seven different wastewater samples in two adjacent counties north of New York City, health officials said.
But based on earlier polio outbreaks, "New Yorkers should know that for every one case of paralytic polio observed, there may be hundreds of other people infected,” the state's health commissioner, Dr. Mary T. Bassett, said in a statement Thursday.
“Coupled with the latest wastewater findings, the Department is treating the single case of polio as just the tip of the iceberg of much greater potential spread," she said. "As we learn more, what we do know is clear: the danger of polio is present in New York today. We must meet this moment by ensuring that adults, including pregnant people, and young children by 2 months of age are up to date with their immunization — the safe protection against this debilitating virus that every New Yorker needs.”
The polio patient in Rockland County is the first person known to be infected with the virus in the U.S. in nearly a decade. Wastewater samples collected in June and July in adjacent Orange County also contained the virus.
Polio, once one of the nation’s most feared diseases, was declared eliminated in the United States in 1979, more than two decades after vaccines became available.
A majority of people infected with polio have no symptoms, but can still shed the virus and give it to others for days or weeks. A small percentage of people who get the disease suffer paralysis. The disease is fatal for between 5-10% of those paralyzed.
All school children in New York are required to have a polio vaccine, but enforcement of vaccination rules in some areas can be lax. Rockland and Orange counties are both known as centers of vaccine resistance. Statewide, about 79% of have completed their polio vaccination series by age two. In Orange County, that rate is 59%. In Rockland it is 60%.
The Orange County wastewater samples were initially collected from municipal wastewater treatment plants for COVID-19 testing.
“It is concerning that polio, a disease that has been largely eradicated through vaccination, is now circulating in our community, especially given the low rates of vaccination for this debilitating disease in certain areas of our County,” said Orange County Health Commissioner Irina Gelman said. “I urge all unvaccinated Orange County residents to get vaccinated as soon as medically feasible.”
