Zhu Asian healing traditions in counseling and psychotherapy (pp. This is the first study showing the dynamic of SARS-CoV-2 concentration in an urban river highly impacted by wastewater and proved that can be used for SARS-CoV-2 surveillance to support health authorities.Novoa, M., & Kedar, E. The experimental and normalized viral concentrations strongly correlated with reported COVID-19 cases thus, Arenales River at AR-2 reflected the epidemiological situation of the city. No human tracers were detected in CR, only HPyV was found in MR-1, MR-2 and AR-1, and both were quantified in AR-2. SARS-CoV-2 was found in about half of samples in low concentrations in La Caldera and Mojotoro Rivers, while it was high and persistent in Arenales River. Instead, Arenales River presented the poorest water quality at AR-2 was negatively affected by the discharges of the southern WWTP, which contributed to significant increase of fecal contamination. ![]() Mojotoro River's water quality was not affected by the northern WWTP of the city. La Caldera River showed the best water quality FIBs were within acceptable limits for recreational activities. Statistical analyses allowed us to verify the correlation between SARS-CoV-2 and the concentration of fecal indicator bacteria (FIB), as well as to find similarities and differences between sampling points. Also, two targets linked to human contributions, human polyomavirus (HPyV) and RNase P, were quantified and used to normalize SARS-CoV-2 concentration, which was compared to reported COVID-19 cases. Fifteen water samples from each point (75 in total) were collected and characterized physico-chemically and microbiologically and SARS-CoV-2 was quantified by RT-qPCR. Five sampling points from three rivers (AR-1 and AR-2 in Arenales River, MR-1 and MR-2 in Mojotoro River, and CR in La Caldera River) from Salta (Argentina), two of them receiving discharges from wastewater plants (WWTP), were monitored from July to December 2020. The aim of this work was to evaluate if rivers could be used for SARS-CoV-2 surveillance. ![]()
