Abstract

Air pollution is an important risk factor for respiratory infections. One of the main components of air pollution is particulate matter (PM), a mixture of solid particles and liquid droplets suspended in the air. Acute respiratory infections are one of the leading causes of death worldwide, therefore, it is critical to understand the mechanism by which PM increases the risk of infections (1).
