The idea that you can stop omicron from spreading within a hospital is quite frankly laughable. Leading virologists are saying this FFS. Its just so infectious. The concept of stopping visitors at that point becomes political and about optics (and stopping legal claims) rather than because its following the 'science'.
BIL has a senior role in one large hospital (doing both clinical and management roles) and pretty much said that there's so many cases now, that they will have to start doing reverse isolation soon due to the logistics of it - ie isolating the covid negative cases rather than the positive ones - because there are less of them.
The situation with covid requring running 'hot' and 'cold' areas requires more staffing to begin with and the current wave is just compounding an already existing pre-covid staff shortage due to an inability to fill positions.
BIL was telling me the % on understaffing expected at this hospital in January and its frankly appalling.
I think it likely covid positive staff who are well enough to work will be given exemption to work on covid hot wards very soon anyway (if its not already happening)
At this point given the reality of the situation, I can't help but think keeping visitors out of hospitals very much is about keeping eyes and ears out to reduce complaints, litigation or whistleblowing rather than anything to do with infection control.
I do think it utterly inhumane on every level to stop visitors under these circumstances. It turns hospitals into prisons and the isolation from families has a very real impact on mental health. We know mental health has an impact on physical health - if you are depressed or anxious it hinders recovery, produces more negative outcomes and lengthens hospital stays. Its something that has been studied and highlights the new for holistic care.
I supported earlier visitor bans to a point earlier on, but omicron is a game changer - and not because 'its milder' but because its just so transmittable. It does change the lens we should be seeing things through but i dont think this has really been understood in terms of its implications tbh.
