Caring for someone self isolating

My brother in law is very poorly with covid-19. He is in hospital but my sister has been allowed to see him since he was admitted 3 days ago. Yesterday it was confirmed it was the virus, my sister was told she could visit him, but would then have to self isolate for 14 days. So yesterday was probably the very last time she would see him as he has many underlying health problems. It’s killing me that I can’t go round and give her a hug to try and comfort her. They have both had an horrendous past 18 months - my sister having had a large brain tumour removed last January. She’s not showing symptoms but I’m worried that if the worse should happen and her husband passes away, we can’t go and see her…


I have pm’d you.
