Not directly, but they are stating they are not recommended, when in fact, they help a bit: - wearing something on your face will help you remember not to touch your face. It's not much, but it's something to reduce spread by hand to mouth contact. - if the mask has good filtration (N95+, sealed on the side), it still offers some protection against dropplet. - if the person wearing it is infected but asymptomatic, they will reduce, at least a bit, the spread (e.g. when sneezing), as long as they're not wearing one with a valve.

So, some protection is better than no protection. Consequently, It's difficult for me to understand why discouraging people from using face masks is a good idea.

Use it properly and keep social distancing, while regularly cleaning your hands.
