In July 2022, CDC was notified of a case of polio in an unvaccinated individual from Rockland County, New York, caused by vaccine-derived poliovirus type 2, and is consulting with the New York State Department of Health on their investigation. Public health experts are working to understand how and where the individual was infected and to provide protective measures, such as vaccinating under- and unvaccinated individuals. In addition, we are aware of the detection of poliovirus (the virus that causes paralytic polio) in wastewater samples (sewage) in several New York locations (including New York City), suggesting likely local circulation of the virus.

As a bordering state, the best way to keep New Jersey residents and children polio-free is to maintain high immunity across the population through safe and effective immunization. All children, adolescents, and adults who are unvaccinated or under-vaccinated should be brought up to date with all routine CDC-recommended inactivated polio vaccine (IPV) doses.

As of January 1, 2023, no poliovirus has been detected in New Jersey.


Report Confirmed or Suspect Cases Immediately to the Local Health Department.

Polio, or poliomyelitis, is a very contagious disease caused by the poliovirus which lives in the throat and digestive tract and invades the nervous system. The virus is found in the stool of infected people. In its most severe form, it causes nerve injury leading to paralysis (cannot move your body), difficulty breathing and sometimes death. People become infected with polio by swallowing the virus. This can happen when infected people do not wash their hands properly after using the bathroom and then touch objects or food that may be placed in another person’s mouth. There is no cure, but there are safe and effective vaccines to prevent polio.
