In November alone, the capital city has reported 2,663 deaths which is 29 per cent of the total fatalities Delhi has witnessed since the outbreak of the pandemic in March. Currently, 6,653 out of 18,708 beds are occupied in the hospitals, 441 out of 7,942 beds in the dedicated Covid Care Centres and 141 out of 562 beds in the dedicated Covid Health Centres.
