Delhi on Sunday recorded the biggest jump in its daily Covid-19 tally with 25,462 fresh cases, while the positivity rate shot up to 29.74 per cent -- meaning almost every third sample being tested in the city is turning out to be positive. At a time on Monday morning, none of the government and private hospitals listed on the Delhi Corona app had a single ICU bed available for Covid-19 patients. Later, around 9 am, the number of ICU beds available in Delhi went up to 100 after the Sardar Patel hospital opened its doors for Covid care. The Delhi government had earlier announced a weekend curfew that ended at 5 am on Monday. However, after a meeting with Delhi Lieutenant Governor Anil Baijal, Delhi Chief Minister Arvind Kejriwal took to addressing residents of Delhi on Monday and announced a strict six-day lockdown in the city.
