Regarding tradesmen going to people's homes who are in isolation especially.
1) the tradesmen going in an urgent circumstance like a boiler breakdown .
2) the customer comes to the door to let the tradesmen in whilst he/she wears a mask .
3) the customer must stay in a separate room whilst the engineer fixes the boiler .
4) once fixed the engineer let's the customer know that the job is done as he leaves the house .
There are no contact and social distancing has to be in force. The people know this before they go in .
But if a family member goes in social distancing will be for the most part will not be enforced.
As the scientists are saying this virus gets transferred more easily with indoor contact .
These measures are in for one reason only and that's to save lives more so with elderly who are mostly on medication for certain illnesses that would put them in massive trouble if they got Covid other that put the hospitals to near breaking point .
