A simplified approach to monitoring the COVID-19 epidemiologic situation using waste water analysis and its application in Russia 2020-09-23 .txt text/plain 1831 123 55 The approach includes i) the creation of a calibration curve on the basis of the serial dilution of excreta collected from people who are infected with COVID-19 and ii) the analysis of wastewater samples and their serial dilutions but the approach excludes usage of concentration techniques before wastewater sample analysis as well as usage of external control in RT-PCR reactions for calculation of numbers of viral particles. 30 In the present study, a modified approach for detection of COVID-19 infection rate using 31 wastewater analysis has been developed. 30 In the present study, a modified approach for detection of COVID-19 infection rate using 31 wastewater analysis has been developed. In the modelling experiment with the excreta of ten COVID-19 235 patients, it was demonstrated that the minimal rate of infected people in the community that can 236 be detected by this method is 10-2%. ./cache/cord-341543-gcnph9gf.txt ./txt/cord-341543-gcnph9gf.txt
