I just thought I'd make a post to advise anyone who is immunosuppressed and showing symptoms to seek telephone advice. For the general population the advice is only to call if you feel severely unwell. I've been prescribed antibiotics and they are putting measures in place for me to have repeat blood tests done, as there is no way to tell if this is an infection due to suppressed immune system or corona.
So please make sure you speak to your GP/specialist as appropriate as I would hate for other illnesses to go unchecked while we're all so concerned about corona.
