It's spread by people entering care homes to work because they fear they cant survive on 20% of their earning when off, so they take chances on going in when unwell. Once in a care home it can decimate. Itls spread by a large amount of the workforce still at work, which is because the definition of key worker has been allowed to be stretched.
No need for confusion. None.
Thats not strictly true Dave.
My sister works in a care home and gets tested weekly. She has been covid positive twice and isolated both times. Once the isolation is over she has to go back because they actually do need people to work not just for wages but to actually look after the people who rely on them.
So it isn't all about folk going in sick for fear of losing money, a lot of people are abiding by the rules but this virus is rife and spreads like wildfire.
