Chronic respiratory diseases now affect more than half a billion people worldwide and their importance as a global health problem has risen dramatically in recent years, prompting intense epidemiological investigation and the launch of numerous initiatives. Across Asia and the Middle East, a variety of environmental exposures increase the risk for the onset or exacerbation of chronic respiratory disease, resulting in a considerable burden of morbidity and mortality. This article outlines new possibilities for public health surveillance of environmental exposures and chronic respiratory disease built around an emerging model of participatory public health: a decentralized approach that involves citizens in the collection and analysis of data, harnesses pervasive technology such as mobile phones and distributed sensors, and provides an open platform for public-private collaboration.
