Resumen
Due to the possibility of wild poliovirus importation from endemic regions and the high
circulation of vaccine-derived poliovirus type 2 in the African region, Mozambique implemented a
surveillance program to monitor the circulation of enteroviruses in the environment. From January
to November 2018, a period that immediately preceded the cVDPV outbreak in Africa, 63 wastewater
samples were collected from different areas in Maputo city. A total of 25 samples (39.7%) were
positive based on cell culture isolation. Non-polio enteroviruses were found in 24 samples (24/25;
96%), whereas 1 Sabin-related poliovirus was isolated. Neither wild nor vaccine-derived poliovirus
was detected. High circulation of EVB species was detected. Environmental surveillance in the One
Health approach, if effectively applied as support to acute flaccid paralysis, can be a powerful aid to
the public health system to monitor poliovirus besides non-polio enteroviruses in polio-free areas.
