In New Delhi, the world's most polluted capital city, the Air Quality Index sank to roughly 93, a level considered moderate, on Monday afternoon. New Delhi's air is regularly considered unhealthy, and AQI averaged around 161 in March 2019, according to IQAir. Air quality is deemed to be good when the number drops below 50. As a result, skyscrapers usually shrouded in smog were visible and some residents reported spotting more stars than usual. Some research also links air pollution to an increased risk of respiratory virus infections - which include COVID-19, the disease caused by the coronavirus.
