Updated statement on report of polio detection in United States

29 July 2022

The Global Polio Eradication Initiative (GPEI) has been informed of a case of paralytic polio in an unvaccinated individual in Rockland County, New York, United States.  

The US Centers for Disease Control and Prevention (CDC) are coordinating with New York State health authorities on their investigation. Initial sequencing confirmed by CDC indicates that the case is type 2 VDPV.  

Following the detection, the Global Polio Laboratory Network (GPLN) has confirmed that the VDPV2 isolated from the case is genetically linked to two Sabin-like type 2 (SL2) isolates, collected from environmental samples in early June in both New York and greater Jerusalem, Israel, as well as to the recently-detected VDPV2 from environmental samples in London, UK. Further investigations – both genetic and epidemiological – are ongoing to determine possible spread of the virus and potential risk associated with these various isolates detected from different locations around the world.

It is vital that all countries, in particular those with a high volume of travel and contact with polio-affected countries and areas, strengthen surveillance in order to rapidly detect any new virus importation and to facilitate a rapid response. Countries, territories, and areas should also maintain uniformly high routine immunization coverage at the district level and at the lowest administrative level to protect children from polio and to minimize the consequences of any new virus being introduced. 

Any form of poliovirus anywhere is a threat to children everywhere. It is critical that the GPEI Polio Eradication Strategy 2022-2026 is fully resourced and fully implemented everywhere, to ensure a world free of all forms of poliovirus can be achieved.
