That is true It should make a difference on a sick person using a mask or not. On the other hand if you are walking down the street yawning and someone sneezes in your direction, you would think a mask would help the situation. I work at a hotel on the island and started wearing a mask just due to the large amount of out of province visitors we have now from Alberta, Ontario and Quebec. If there’s a chance it makes a difference, I’d rather have it than not.
