The viability of virus was determined after treatment with different disinfectants and pH solutions at room temperature (20∼25(o)C). SARS-CoV-2 could be detected under a wide range of pH conditions from pH4 to pH11 for several days and 1 to 2 days in stool at room temperature but lost 5 logs of infectivity. One hundred microliters of SARS-CoV-2 with 114 10 6.5 TCID 50 /ml was added into each bottles of 0.9 ml VTM and incubated at room temperature 115 (20-25 o C). When SARS-CoV-2 was added in VTM with pH ranging from 2 to 13, the virus remained 163 viable up to 6 days but lost between 2.9 and 5.33 logs of infectivity from pH5 to pH9 and up 164 to 1~2 days in pH4 and pH11 ( Table 2) . ./cache/cord-341069-kngf6qpe.txt ./txt/cord-341069-kngf6qpe.txt
