Hong Kong CNN —Indonesia’s capital Jakarta is the world’s most polluted city, according to a new study, and the country’s president may have the cough to prove it. Uno said doctors were still diagnosing the cause of Widodo’s cough but added that it might be related to the worsening air quality, reported CNN affiliate CNN Indonesia. But in recent weeks air quality in the capital has become particularly bad, deteriorating to the worst in the world, according to data provided by IQAir, a Swiss air quality technology company. On August 9, Jakarta topped its list of polluted cities after registering “unhealthy” air pollution levels nearly every day, the company said. “Air pollution is a serious problem in Southeast Asia,” said political analyst Bridget Welsh from the University of Nottingham.
