I've no idea how common it is. But I've been diagnosed as having it today. I've had pneumonia twice in the last year, am an asthmatic (since early childhood, quite severely) and since January have been feeling intermittently fluey, wheezy and coughing up alien-like substances.
The chest clinic consultant did a CT scan of my lungs and a blood test for allergy to aspergillis. The scan showed inflammation in my lungs and the blood test was positive so he wants me to take long-term steroids orally (I already have strong steroid inhalers for asthma).
I'm just digesting all this really and wondered if anybody had any experience of it? I'm posting way too late and have to go to bed now but will check in the morning.
