| It wasn't hard to find sources that disagree: > The use of masks, which are medical devices, requires correct use, based on medical principles unfortunately not known by the whole population. This cultural deficiency, linked to the breathing difficulties caused by the use of this filter, has led to incorrect management of these important medical devices, facilitating the commission of errors that can make the masks ineffective or *even dangerous because they can become a vehicle for the spread of the disease itself*. https://www.sciencedirect.com/science/article/pii/S092575352... That article cites a WHO statement: > Using a mask incorrectly however, may actually increase the risk of transmission, rather than reduce it. https://www.who.int/csr/resources/publications/Adviceusemask... Edit: what is wrong with people here, downvoting quotes from scientific articles and WHO statements, because they don't like what they say? |
Read your link. Proper usage isn't hard to understand. If you touch your mask with your dirty hands it might increase the chance that you breathe in the germs that were on your hands.
Don't put a dirty mask on your face. Don't touch your mask with dirty hands.
Notice that these messages are different than "masks are a mind-control conspiracy" and "masks are ineffective."
