thank you for using healthcare magic. Bronchitis is more commonly caused by a viral insult. So there is really a good chance he can get it repeatedly if he will be infected by the common virus (usually from other sick kids in school). So nebulizations (and other supportive treatment) can do the job in this instance. But sometimes bronchitis can be from a bacterial cause which needs to be treated with additional medicines like antibiotics. It is best that you see your doctor in order to distinguish which is which and possibly do some diagnostic test. furthermore, you should also be aware of other illnesses that can have the same symptoms with bronchitis like Asthma which should be addressed/treated differently. sincerely, Mark Rosario MD pediatric pulmonology
