Is liquid chalk an effective disinfectant of SARS-CoV-2 and influenza viruses?

By | June 22, 2021
A recent study, published in the American Society for Microbiology’s journal, mSphere, evaluated the use of many liquid chalk products as antiseptics against the transmission of highly pathogenic human viruses such as influenza A virus (H1N1), SARS-CoV-2, (IAV), and norovirus in a mouse norovirus (MNV) model. The researchers applied chalk before or after virus inoculum and determined the recovery of infectious virus to mimic its use in the gym setting.
