Polio Virus Now Also Found in Orange County, NY DOH Officials on High Alert


More polio has been detected in Hudson Valley wastewater samples, this time Orange County, according to NYS health officials, which it says further indicates potential community spread of the virus declared eradicated in 1979.

The CDC detected polio in samples taken from June and July in two geographically different locations in Orange County and has linked those to samples from Jerusalem, in Israel, and recent samples from London, England.

The Rockland County case was an unvaccinated patient who had a vaccine-derived strain of the virus that indicates it would have been contracted by someone who got a live dose used by a country outside the US; in rare instances, people given the live virus can spread it to other people who haven’t been vaccinated.

See full statement below from the New York Department of Health:

Albany, N.Y. (August 4, 2022) – The New York State Department of Health (NYSDOH) today updated New Yorkers on the poliovirus in New York State. Following the identification of polio in early June wastewater samples in Rockland County, the virus has now also been detected in wastewater samples from June and July in two geographically different locations in Orange County and July samples from Rockland County.

Sequence analysis by the Centers for Disease Control and Prevention (CDC) has found that seven positive samples from both Rockland County (three) and Orange County (four) are genetically linked to the individual case of paralytic polio previously identified in a Rockland County resident. These finding provide further evidence of local—not international—transmission of a polio virus that can cause paralysis and potential community spread, underscoring the urgency of every New York adult and child getting immunized, especially those in the greater New York metropolitan area. NYSDOH will continue its active, ongoing wastewater surveillance efforts in partnership with CDC.

“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,” State Health Commissioner Dr. Mary T. Bassett said. “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. 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.”

New Yorkers should know that the latest environmental findings do not indicate that the individual identified in Rockland County was the source of the transmission, and case investigation into the origin of the virus is ongoing. NYSDOH continues to work with global, national, and local public health authorities to aggressively assess the spread of the virus and ensure prevention measures, particularly immunization clinics, are in place – as the best way to keep New York polio-free is to maintain high immunity across the population through vaccination.

All New Yorkers who are unvaccinated, including children by 2 months of age, those who are pregnant, and people who have not completed their polio vaccine series previously should get immunized right away. Unvaccinated New Yorkers who live, work, go to school in, or visit Rockland County, Orange County, and the greater New York metropolitan area are at the highest risk of exposure.

A core component of CDC’s NYSDOH for all school-aged children, most children are already vaccinated. New Yorkers who are unsure of their vaccination status, or that of a loved one, should reach out to a healthcare provider right away to get vaccinated or receive a booster. As of August 1, 2022, Rockland County has a polio vaccination rate of 60.34 percent and Orange County has a polio vaccination rate of 58.68 percent, compared to the statewide average of 78.96 percent, among children who have received 3 polio immunizations before their second birthday.*

“This unprecedented circulation of polio in our community from a devastating disease that was eradicated from the United States in 1979 must be stopped. Any unvaccinated children and adults should receive a first polio immunization immediately. The Rockland County Department of Health is here to help residents receive vaccinations. Visit our webpage for more information,” Rockland County Department of Health Commissioner Dr. Patricia Schnabel Ruppert said.

“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,” Orange County Health Commissioner Dr. Irina Gelman said. “I urge all unvaccinated Orange County residents to get vaccinated as soon as medically feasible.”

While there is no cure for polio, it is preventable through safe and effective immunization. According to CDC, inactivated poliovirus vaccine (IPV), which is the only polio immunization that has been given in the United States since 2000, protects 99% of children who get all the recommended doses.

NYSDOH has increased communication to healthcare providers, stressing the importance of testing and the on-time administration of the polio vaccine among their patients. In accordance with CDC:

– All children should get four doses of the polio vaccine, with the first dose given at 6 weeks through 2 months of age, followed by one dose given at 4 months of age, 6 through 18 months old, and 4 through 6 years old.
– Adults who are unvaccinated or are unsure if they have been immunized should receive 3 doses.
– Adults who have only had 1 or 2 doses of the polio vaccine in the past should get the remaining 1 or 2 doses – it does not matter how long it has been since the earlier doses.

Adults who are at increased risk of exposure to poliovirus and who have previously completed a routine series of polio vaccine (IPV or OPV) can receive one lifetime booster dose of IPV.

Polio is a serious and life-threatening disease. Spread from person-to-person, polio is very contagious, and an individual can transmit the virus even if they aren’t sick. Asymptomatic spread is a high concern among health officials, particularly following the identification of a paralytic, symptomatic polio case. Based on evidence from earlier polio outbreaks, health officials estimate that for every one case of paralytic polio observed, there may be hundreds of other people infected.

Symptoms of polio, which can be mild and flu-like, can take up to 30 days to appear, during which time an infected individual can be shedding virus to others. Some polio cases can result in paralysis or death. According to the WHO, of those paralyzed, 5-10% die when their breathing muscles become immobilized.


  1. This polio business is not a joke. If people don’t care about themselves , please think of others. Now being this is detected in 2 prominently Jewish areas, we are being blamed again. What is wrong with people not getting vaccinated? This must end
    Schools cannot allow children into school with out vaccines. YESHIVAS WAKEUP.
