I have been worrying about this and thought perhaps someone might know how this is being handled. Apologies if it reads as scare mongering, I do not wish to be alarmist.
It does not affect me directly, but I do know many people of various ages who either live alone or who live with very young children and no other adult in the house.
Due to increasing pressure on the NHS, it will obviously not be possible to admit everyone with moderate symptoms (CV or otherwise) to hospital.
From many reports it appears that you probably won't get an ambulance until you are struggling to breathe/incoherent and confused. (No criticism of the emergency services intended, I know they are under great strain).
At which point, you rather rely on someone else calling the ambulance for you.
So what is in place when there is only one adult in the house? Are they more likely to be taken in sooner rather than later as a precautionary measure?
If someone has been in contact with the NHS (phone or internet) with moderate symptoms is there a follow up procedure in place? Procedures if someone stops answering their phone?
Could the NHS responder volunteers be mobilised to perform welfare checks?
I know that this will be an issue for those falling ill alone even without Coronavirus, but surely exacerbated now by social distancing.
A side note: when DD was small and dh used to work away from home for weeks at a time, I coached her from a young age on what to do if something happened and made sure she knew our address. I know that sounds super morbid (and I did it in a way that didn't scare her) but I think it is worth considering.
