Kolkata has not reported a single case of the new coronavirus, which has killed 800 people and infected over 37,000 across the world, but is still feeling the pinch of the outbreak. A two-hour flight away is the Chinese city of Kunming in the Yunan province. Scores of students go to colleges there and it is a busy base for trade across China. But all that activity has come to a standstill and Chinese citizens too are affected. Not only is India not giving visas any more, Chinese citizens who work in Chinese companies in Kolkata were not allowed to board a flight earlier this month though they had work permits.
