Pediatric asthma is a heterogeneous and common chronic condition with significant morbidity and burden on the healthcare system. Despite advances in the field, the disease has proven to be increasingly complex to diagnose and management strategies are constantly evolving. Studies from 2020 have advanced the field even further, particularly with regard to new methods of diagnosis and monitoring, treatment of severe asthma, modifiable risk factors like exercise and obesity, aerosol delivery, and viral respiratory infections contributing to the development of asthma. Continued studies are needed to improve our care for children with asthma and we look forward to future advances. This article is part of our 2020 "Year in Review" series, in which we summarize publications in major topic areas, in the context of selected literature from other journals relevant to our discipline.
Keywords: aerosol biology; asthma and early wheeze; epidemiology; special dimensions of pulmonary medicine.
