- New study, done by South Korean scientists, shows that “neither surgical nor cotton masks effectively filtered SARS–CoV-2 during coughs by infected patients.”.
- Even though previous research shows these masks were effective for influenza, they are not an effective way to stop the spread of COVID.
- Scientists don’t know yet how much of the virus is transmitted during coughing.
- It’s worth noting, that the COVID contamination was actually bigger on the outside of the masks, than on the inside.
