Increasing awareness regarding the relationship between environmental exposures and allergic disease.

This review highlights studies from the past 3 years that add to the understanding of the impact of environmental exposures on allergic disease. These include aeroallergens, air quality, prenatal or early-life exposures, and occupational exposures. Recent studies have focused on the relationship between the environment, the microbiome, and allergic disease, and new therapeutic options have also been reviewed. Lastly, there has been significant recent research improving our knowledge of the link between health disparities and environmental exposures. These scientific advances have resulted in a better understanding that sets the foundation for current and future research dedicated to improving health outcomes by modifying environmental exposures.
