Something I found interesting was this: I caught Hep C when I was 27 yrs old, and in the same year, sufferd my first bout of "adult onset asthma". Ever after that, every time I caught a cold, it would immediately turn into the worst asthma. Also, none of the inhalers, or stronger cortocosteroids would work, in the least bit. I was terrified of catching a bad flu, and almost died(woke up at night, wheezing, dry hacking, breathless) the time I caught Whooping cough, 7 yrs ago.
Now, since I started my Tx last Feb, and haven't had a single asthma wheeze since! I was waiting, to see what would happen when I caught a cold bug, which I now have. My only symptom is a runny nose and sneezing. Not fun, but very mild, and much better then when I had Hep C, and the asthma symptoms!
