How long will I be contagious due to bronchitis?

ANSWER

It depends on the type of virus that you have. In most cases, you’ll be contagious for a few days, and possibly as long as a week. Since you may not know what kind of illness you have -- and doctors don’t test for individual viruses, since there are hundreds of them -- it’s best to assume you could spread the disease while you have cold symptoms.
