You are the one making negative assertions.
The advice is still to stay at home and work from home. If you got to work try NOT to use public transport. If you use PT you will need to wear face covering because the 2m rule is very hard to maintain.
When normal shops open it may then be wise to use face coverings but not yet.
The social distancing and stay at home as much as possible is still the main way to reduce infections and will be for several more months
I am curious to know why you think it is not wise to wear a mask now, but wise to wear one in two to three weeks time.
