While the debate about “social distancing”, masks, and infringement of our civil liberties reaches new heights. Previous reports on mask efficacy cite tests done with influenza, a study has now tested whether masks stop the SARS-COV-2 virus.
Study had patients with Covid19 cough with masks on, then tested the outside & inside of mask, as well as a petri dish placed in front of mask for presence of virus. The results show that virus was present afterwards on all three surfaces.
Both cloth and surgical masks were tested.
