Is bronchitis asthma contagious?

Let's be clear: asthma is a chronic respiratory condition and 100% non-contagious. Infectious bronchitis is caused by bugs, so that definitely spreads. If you are sick, isolate yourself and see a doctor.

My sister has asthma and we have lived together for years; I never caught it because it is not contagious. But last year she got viral bronchitis, and the whole family got a cold. From my experience, only the infection part spreads.

Asthma isn't something you can catch from someone. But viral bronchitis is contagious, so if you are working out at a gym, make sure to wipe down the equipment and take rest till you recover.

Haan, asthma toh bilkul nahi phailta, voh toh allergy hai na. Par agar viral bronchitis hai, toh uske virus se baki logo ko cold ho sakta hai. Thoda door hi raho jab tak unka cough theek nahi hota.

I am a bit confused about this. My roommate has a bad cough and says it is just her chronic asthma, but she also has a cold. Can her cold turn into infectious bronchitis for me? Should I sleep in a different room?

I was reading about this because my colleague has a heavy cough. Asthma is definitely not contagious. But if they have bronchitis caused by a common virus, you can catch the virus. Best to keep some physical distance.
