NEW DELHI, Jan 4: Delhi Chief Minister Arvind Kejriwal has tested positive for covid. He tweeted on Tuesday morning that he is isolating himself at home and has only mild symptoms.

The Aam Aadmi Party (AAP) leader has been in the past few days on a hectic tour of Punjab, Uttarakhand and Uttar Pradesh which are going to the hustings in the coming months.

"I have tested positive for Covid. Mild symptoms. Have isolated myself at home. Those who came in touch with me in last few days, kindly isolate yourself and get yourself tested," Chief Minister's post said.

Delhi reported 4,099 new cases in the 24 hours and the the test positivity rate (TPR) is 6.46 per cent, a steep climb from less than 0.5% a few days ago. One death also occurred on Monday. Currently the Capital is under a Yellow Alert, closing schools and colleges and cinemas, restricting travel by transport like Metro to 50% capacity and malls and markets going on an 'odd-even' pattern of working.

"As per genome sequencing reports (of past few days), 81 per cent samples were infected with Omicron. Most of the cases are of Omicron," Health Minister Satyender Jain had said on Monday.

With TPR crossing the threshold of 5%, Delhi is in for a Red Alert mandating total lockout. A DDMA decision is expected any moment.
