With a surge in COVID-19 infections in Delhi, hospitals are also witnessing a slight increase in admissions, but most of these patients, doctors say, have comorbid conditions.

The national capital had recorded 1,383 fresh coronavirus cases with a positivity rate of 7.22 per cent and one fatality on Tuesday.
On Monday, Delhi had logged 1,060 new Covid cases and six deaths, the highest in over four months, while the positivity rate had risen to 10.09 per cent. This was the highest case positivity rate recorded in the national capital since January 24, when 11.8 per cent of the people tested had turned out to be positive.
Also, the single-day death toll of six was the highest since February 13, when 12 people had succumbed to the viral infection.
Despite the rise in the positivity rate, the city government has not implemented the Graded Response Action Plan (GRAP) devised by the Delhi Disaster Management Authority (DDMA) since hospital admissions are low.
The GRAP came into force in August last year, stipulating measures to be taken by the government in accordance with the positivity rate and bed occupancy for the locking and unlocking of various activities.
Experts have said people lowering their guard and travelling during the vacation season are the main reasons behind the latest upward trend in the number of coronavirus cases in Delhi.
The number of daily COVID-19 cases in Delhi had touched the record high of 28,867 on January 13 during the third wave of the pandemic. The city had recorded a positivity rate of 30.6 per cent on January 14, the highest during the third wave of the pandemic.
