Alert
As of April 1, 2025, no poliovirus has been detected in New Jersey.
A confirmed case of paralytic poliomyelitis was identified in July 2022 in Rockland County, New York in an unvaccinated adult. Wastewater surveillance detected genetically related poliovirus between April 2022 and February 2023 in New York, suggesting the presence of other asymptomatic or non-paralytic polio cases. Poliovirus can spread where vaccination rates are low.
As a bordering state, the best way to continue to keep New Jersey residents, especially children, safe from polio is to maintain high immunity across the population through safe and effective vaccination. All individuals – children and adults – who are unvaccinated or incompletely vaccinated against polio should be vaccinated according to the ACIP routine and catch-up schedules.
PLEASE NOTE: Blood tests to assess immunity for people with no or questionable documentation of poliovirus vaccination are not recommended because of increasingly limited availability of antibody testing against type 2 poliovirus. If polio vaccination status is unknown and vaccination records cannot be located, it is recommended to complete the polio vaccination series with inactivated polio vaccine (IPV), especially before travel to destinations considered at increased risk for polio.
