Areas with Ongoing Poliovirus Circulation

At a glance

The guidance outlines measures to mitigate the risks associated with poliovirus potentially infectious materials (PIM) in laboratory and non-laboratory settings. Contact the U.S. NAC at poliocontainment@cdc.gov for additional guidance.

Overview

This guidance applies to laboratories and various facilities that collect, handle, or store infectious materials in or from areas known or suspected to have circulating polioviruses.

These are non-essential poliovirus facilities and include:

  • Public health and clinical testing laboratories
  • Research and environmental testing laboratories
  • Healthcare providers
  • Vaccine producers
  • Storage facilities
  • Facilities that treat human waste and sewage.

Polio identification

This interim guidance from the U.S. National Authority for Containment (NAC) is based on the World Health Organization's (WHO) guidance documents: Global Action Plan, 4th edition (GAPIV) and Potentially Infectious Materials (PIM).

Contact the U.S. NAC at poliocontainment@cdc.gov for additional guidance.

A single U.S. paralytic polio case was identified in a person in Rockland County, New York, in July 2022. Vaccine-derived poliovirus (VDPV) was detected in subsequent local wastewater samples from multiple counties in the surrounding geographical area. The polioviruses identified from the New York paralytic polio case and wastewater samples met WHO’s criteria for circulating vaccine-derived poliovirus.

Guidance for laboratories

What You Need to Know

Laboratories in areas of ongoing poliovirus transmission should:

  • Implement measures to mitigate the risks to personnel handling VDPV PIM.
  • Inactivate PIM using a validated method. See Policy for U.S. Facilities to Inactive Poliovirus Materials.
  • Report VDPV PIM retained for thirty (30) days or more to the U.S. NAC and notify U.S. NAC of PIM samples transferred to other facilities.
  • Store PIM separately from non-PIM.
  • Destroy any unneeded or nonessential VDPV PIM and complete a NAC Destruction Attestation form.
