Once samples are collected, NYSDOH and its partners work with CDC, who conduct PCR testing for poliovirus and perform sequence analysis to understand if polio is present, if the type of poliovirus present is of concern, and if the strain identified is genetically-linked to the case of paralytic polio identified in Rockland County. NYSDOH works with a network of partners to collect and store wastewater samples. This makes wastewater surveillance critical to identifying poliovirus among both asymptomatic and symptomatic people. Wastewater samples – which are based on water from our sewage system – collect and treat feces flushed down the toilet. However, individuals infected with polio shed virus in their stool. Polio is highly contagious, and people can spread the virus even if they don't know they're sick. This monitoring helps identify where the virus may be and when, though it does not provide quantitative information about who or how many people or households may be infected. Wastewater surveillance is an important public health tool, providing the early and ongoing detection of polio in communities. It does not contaminate New York drinking water, including tap water, streams, and lakes. Wastewater collected in sewer systems in New York cannot be a source of polio infection or transmission for the general public.
