Acute bronchitis can be caused by contagious pathogens. Acute bronchitis generally follows a viral respiratory infection. Typical viruses include respiratory syncytial virus, rhinovirus, influenza, and others. At first, it affects your nose, sinuses, and throat and then spreads to the lungs. Sometimes, you may get another (secondary) bacterial infection in the airways. This means that bacteria infect the airways, in addition to the virus.
The following things can make bronchitis worse: air pollution; allergies; certain occupations (such as coal mining, textile manufacturing, or grain handling); infections.
