Poliovirus Containment

upside down jar icon with microorganisms appearing to float insideAs part of our commitment to minimize the risk of poliovirus release from our research and diagnostic laboratories, UW-Madison must report the acquisition or discovery of any poliovirus potentially infectious materials (PIM) to the U.S. National Authority for Containment of Poliovirus (NAC) at the Centers for Disease Control and Prevention (CDC).

Poliovirus PIM are any materials that may unknowingly contain poliovirus because they were collected at a time and place where poliovirus was in circulation or oral polio vaccine was in use.  Examples include certain clinical specimens, such as respiratory secretions and fecal samples, respiratory or enteric viral isolates and environmental water samples.

All UW-Madison principal investigators must report any changes in their laboratory’s PIM inventory to the Office of Biological Safety (OBS).  This includes the identification or acquisition of new PIM and the disposition or disposal of existing PIM that was previously reported to OBS or the NAC.
