Abstract
The current outbreak of coronavirus disease (COVID-19) has led to creating a public health emergency conditions since 2019. COVID-19, which is caused by SARS-CoV-2, is spread via human-to-human transmission by direct contact or droplets. Through conducting this study, we were looking for detecting SARS-CoV-2 in wastewater produced in Iran country (Ardabil, Nir, Khalkhal and Givi) (wastewater collection network, wastewater treatment plant and hospital wastewater). In this research, samples (n = 76) were collected from influent and effluent of municipal and hospital wastewater treatment plants and some samples were also collected from Ardabil municipal wastewater manholes. The sampling duration included the white (lower risk of covid-19) and red (high risk of covid-19) conditions. Samples were stored at -20°C for further diagnostic tests. Out of 76 samples, a total of 16 samples (21.05%) collected from wastewater in Ardabil province (Ardabil, Nir, Khalkhal, and Givi), were positive in terms of SARS-CoV-2. Wastewater epidemiology can facilitate detection of the incidence of pathogens through metropolises, measurement of population prevalence without direct testing, and provision of information to public health system about the efficiency of intervening efforts.
