Lateral flow test twice a week in ours
BUT they are really really not very accurate. I had Covid as did my DH and the lateral flows were negative when we had symptoms and had positive PCRs.
We all use PPE scrupulously
No-one would come to work if they had symptoms or were a contact (no incentive to as you get paid anyway and no pressure to either)
Nonetheless we still have had outbreaks on a number of wards and yes it's likely that it was brought in by staff as the patients are isolated on admission.
However to blame staff for that is not on. Staff have kids who go to school and nursery. Nurses and Drs are very often married to other nurses and Drs who might work in a different healthcare setting and pick it up there. Or they could get it at the supermarket like anyone could.
The day I started to have COVID symptoms in the evening I had already worked a full day. My lateral flow was negative that very morning and I felt well. I had no idea at all that I had COVID. I used all my PPE.
Fortunately I did not give it to any patients (the outbreak was a month later and was traced to another staff member) but the guilt that I might have was indescribable.
Staff cannot be blamed for transmitting Covid in a COVID pandemic. We try very very hard not to and for 11 months we were successful but the local cases are so high that one was bound to get through eventually.
The government is to blame NOT individual care workers. Please please do not add to the guilt they already feel.
