Liquid chalk is an antiseptic against SARS-CoV-2 and influenza A respiratory viruses 2020-11-02 .txt text/plain 1411 85 56 We investigated whether liquid chalk is an antiseptic against highly pathogenic human viruses including, SARS-CoV-2, influenza virus and noroviruses. We observed that addition of chalk before or after virus contact lead to a significant reduction on recovery of infectious SARS-CoV-2 and influenza but had little impact on norovirus. To further our study, we also tested the antiviral effect of Liquid Chalk against another 155 highly infectious and pathogenic respiratory viral pathogen IAV. 157 As can be observed in Figure 2 , all four Liquid Chalk products were effective in restricting the 158 recovery of IAV compared to SARS-CoV-2. transmission of SARS-CoV-2 (the 52 causative agent of the COVID-19 pandemic), influenza A virus (H1N1) (IAV) and norovirus, 53 using the surrogate model of mouse norovirus As a comparator, we also investigated the ability of Liquid Chalk to inactivate another 178 highly infectious viral pathogen, norovirus. ./cache/cord-313795-jr3n3uo9.txt ./txt/cord-313795-jr3n3uo9.txt
