ABSTRACT
Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which causes COVID-19 disease, is accompanied by the presence and dissemination of the virus in the feces of symptomatic and asymptomatic individuals. Several studies have pointed out the presence of virus fragments in the environment and viral loads for long periods in sewage systems and wastewater. The rapid spread of the infection has severely impacted public health and the global economy, demanding coping strategies and solutions for the pandemic. In this study, sewage-based epidemiology (WBE) was adapted as a complementary methodological strategy to clinical monitoring of the occurrence of COVID-19 in Porto Alegre. For 12 months, starting in August 2020, biweekly composite collections of water, flow determination and field parameters were carried out at the mouth of the Diluvio stream. From these samples, analyzes of quantitative viral RNA and water quality parameters associated with sewage discharges were performed. During the period evaluated, a correlation was observed between the concentration values of virus particles at the mouth of the stream and the number of clinical cases of COVID-19 officially notified by the State Health Department for Porto Alegre. The results, partially presented here, demonstrate the efficiency of the WBE strategy applied to the urban watercourse, in monitoring the SARS-CoV-2 pandemic.
