Timeline of patient activities, potential poliovirus exposures, shedding, and poliovirus-positive wastewater samples genetically linked to a patient with a case of type 2 vaccine-derived poliovirus (New York, May to August 2022)

Abbreviations: ED = emergency department; VDPV2 = type 2 vaccine-derived poliovirus. Wastewater, also referred to as sewage, includes water from household or building use (eg, toilets, showers, and sinks) that can contain human fecal waste and water from non-household sources (eg, rain and industrial use). Note that more than one positive wastewater sample might have been collected on the same day in Rockland County or Orange County. (Source: Link-Gelles R, Lutterloh E, Schnabel Ruppert P, et al.
