Is asthmatic bronchitis and bronchospasm contagious? If so, for how long?
Asthma is not contagious. Bronchitis itself is not a contagious illness, but sometimes it is brought on by an upper respiratory infection, which could be contagious. Your best bet is to wash your hands thoroughly before preparing food or touching anyone else and to cover your mouth/nose with a tissue when coughing or sneezing.
Hope you are feeling better soon,
P.S. Here are some links about bronchitis and other cold/flu-related subjects that you might find helpful:

USUALLY astmatic bronchitis is not contagious. It can, however, be caused by a bacteria or virus that is contagious ask your docor, he will guide you. It is usally caused by an inability to clear mucous. Bacteria and viruses love to grow in the collected mucous. Bronchospasm is definately not contagious. It is a muscle spasm-nothing more.
I have had asthmatic bronchitis more times that I can count. I work with high risk children who can get sick easily and have never given bronchitis to any of them.
