NEW DELHI, India — Weaving through traffic in central New Delhi, Bharat Singh takes his hand off the throttle of his sputtering, three-wheeled rickshaw — India’s cheap alternative to a taxi — and coughs into his fist.
“By the time evening comes around, I’m coughing like crazy and my eyes are red and burning,” he says, speaking Hindi.
“I can’t get to sleep because of the headaches, and when I finally do fall asleep, my coughing wakes me up again.”
