With over 11,000 new Covid cases in the past 24 hours - and nearly 20,000 in the 48 hours prior - Delhi is now third on the list of states reporting the most number of new cases every day. The city also reported 72 Covid-linked deaths on Monday - the most in a day since December 5. Concurrent with that spike is a three-fold increase in demand for oxygen cylinders and concentrators among the 17,000 people in home isolation across the national capital.
