Yes, that's it Squad. It was the doctor at the hospital who told my Mum (the patient's sister) that it was double pneumonia. Just a thought, but he may as well have used the correct term, if laymen don't understand the terminology! They may as well not understand the correct term as not understand a layman's term - if you see what I mean.
Thank you for explaining Squad; so what will be his treatment long-term. At the minute he has had steroids (again) and antibiotics plus an oxygen mask which is making him feel MUCH better.
