Prognosis of occupational asthma

Background: Occupational asthma (OA), is an important clinical condition with substantial morbidity and associated costs. Since the original description of OA we have learned a great deal about the natural history. The prognosis of OA is determined by many factors. These factors and confounding variables in the presentation of OA will be presented. Results: A review of the available literature indicates that OA may have complete resolution or may persist for years following its initial presentation. Conclusion: The importance of timely removal or adequate respiratory protection from potential sources of OA is highlighted.
