The first round of sero survey in Delhi had revealed that an estimated 22.6% had antibodies against Covid-19, which translates into about 4.5 million people in Delhi having had the infection. For this survey, 29% of the total samples had antibodies against Covid-19, which translates to about 5.8 million of Delhi’s 20 million population.
