The number of daily cases had started to come down in February. On February 26, the month's highest daily count of 256 cases was recorded.
However, the daily cases started to rise again in March and it has been steadily increasing over the past few days.
Health Minister Satyendar Jain had on Saturday dismissed any possibility of imposing another lockdown in Delhi, saying it was not a solution to check the spread of the coronavirus that is again surging rapidly.
The minister had said there were enough hospital beds available for coronavirus patients and it could be increased if the need arises.
Health experts and doctors have attributed this "sudden rise" in cases to people turning complacent, not following COVID-appropriate behaviour and "assuming all is well now".
The next two-three months could be challenging, they said, adding the situation can be kept under control if vaccination is opened up for more people and COVID-19 protocols are strictly adhered to.
The Delhi Disaster Management Authority had on Tuesday ordered that there will be no public celebrations in the national capital during upcoming festivals such Holi and Navaratri.
Jain had said action will be taken against those found violating the directions issued for Holi celebrations.
