penny, they can catch it with the masks. Most of the masks now carry a warning that they do not protect against getting, or spreading Covid. The concern about masks, is the reduced air flow, and higher carbon dioxide levels, when using them. This can actually be dangerous for children, and people with respiratory issues. The masks that actually work best, are rarely the ones people are using. If you want the protection you are seeing in some of the illustrations, you need to get Medical Grade N95 masks that are properly sealed on the face. Even those don't offer 100% protection, but they do offer a much higher degree of protection. With the higher degree of protection, the length of time they should be worn, and the risks from reduced oxygen, and higher carbon dioxide levels, is higher too.
