@windwalker Terri.... hard to pinpoint how/where I got the bronchitis from this year....we flew for weekend to San Diego to be with son and his 2 year old...who had continuous cold and vomited the evening we left....then another flight to Denver where 8 year old, daughter -,son -in -law all had colds...then an hour with NJH doctor in small room while she had mask on for a cold...then back on plane!!! I rationalized the bronchitis and sinusitis by knowing a) had one bout vs 3 like 2018 b) did not get influenza A like last year . Thanks for asking Terri tdrell
