cord-328686-5ik5em5a	Zhao, L.	First study on surveillance of SARS-CoV-2 RNA in wastewater systems and related environments in Wuhan: Post-lockdown	2020-08-21		.txt	text/plain	1606	110	61	In the present study, SARS-CoV-2 RNA was concentrated from wastewater, sludge, surface water, ground water, and soil samples of municipal and hospital wastewater systems and related environment in Wuhan during the COVID-19 middle and low risk periods, and the viral RNA copies quantified using RT-qPCR. From the findings of this study, during the middle risk period, one influent sample and three secondary treatment effluents collected from Waste Water Treatment Plant 2 (WWTP2), as well as two influent samples from wastewater system of Hospital 2 were SARS-CoV-2 RNA positive. . https://doi.org/10.1101/2020.08.19.20172924 doi: medRxiv preprint From the findings of this study, during the middle risk period, positive samples were detected both in 83 municipal and hospital wastewater systems. . https://doi.org/10.1101/2020.08.19.20172924 doi: medRxiv preprint Although SARS-CoV-2 RNA surveillance in wastewaters is a useful WBE drive, the public health risk associated 109 with water cycle is unclear since viral particles infectivity in sewage and faeces is yet to be determined in 110 addition to its probable fecal-oral transmission.	./cache/cord-328686-5ik5em5a.txt	./txt/cord-328686-5ik5em5a.txt
