@alreadytaken at my home all the staff tested negative. At my relatives home all the staff moved in when visits from family/friends stopped, this was about 2 weeks before lockdown.
Not all homes are the same, with my relatives home it is pretty obvious that the man who was discharged from hospital with covid was the source for the other residents.
I imagine London, and other big cities, are very different to most of the South West. In the homes I know, including the one I work in, the staff turnover is very low and they don't use agency staff. I think that is reflected in the rates.
@MRex well if some of the discharged people had covid it was obviously in the hospital they were discharged from. I imagine in Torbay it would be mainly from Torbay Hospital, I don't think they would be clearing Brixham for covid patients and Paignton is just a well being centre now. They might come from further away, Dartmouth/Totnes or somewhere but I would have thought they'd be more local. I think it would be more likely that Torbay would be releasing to other towns than other towns releasing to Torbay but I suppose it would be interesting to know. I'm not sure how often Torbay residents would go to city hospitals, like Derriford or RD&E.
It will be interesting when this is studied when it is all over.
