She's 13 and she has asthma (as does DH). DH got his jag early as he is classed as vulnerable (not CEV though).
All the parents of those who have tested positive say their DDs have been really unwell for about 2 weeks - headaches, fatigue, runny nose, fatigue.
Also friend's DD (who is 17) has long covid.
I think it's the fear of the unknown especially with asthma and its understandable but unfortunately this illness isn't going anywhere.
I have asthma and although I got a moderate case (I'm donkeys older than your daughter though at 34 when I got it) actually having asthma in a weird way helped me!
The research studies show that asthmatics already have a lot of the tools available to them such as the reliever pump and knowing how to ease breathing etc so actually they are less likely to end up in hospital. Also me being an asthmatic meant I got prescribed steroids very quickly and easily when my DH contacted 111. This helped hugely!
There are several ongoing studies into what makes people more susceptible to long covid one of which is having glandular fever.
Best thing is to be prepared, have a oximeter and if she does get it then ensure that she rests but also not be concerned about contacting 111.
The biggest issue we face in Scotland is the govt flat refusal to set up long covid clinics to help people.
If your friends DD doesn't already know taking vit b complexes, magnesium, high strength vit D, curcumin and umbiquinol (this one is the most expensive) can help ease the fatigue. They take a while to take effect but sooner she can start the better!
