Delhi Health Minister Satyendar Jain has been hospitalised due to 'high-grade fever'.
He developed a fever and his oxygen level dropped on Monday night.
Jain has been admitted to Rajiv Gandhi Super Speciality Hospital (RGSSH).
The health scare came a day after Jain attended an all-party meeting chaired by Union Home Minister Amit Shah.
Delhi Chief Minister Arvind Kejriwal was also present at the meeting.
Last week, Arvind Kejriwal had gone into self-isolation at his home.
He had a bout of fever and complained of sore throat.
Kejriwal had later tested negative for coronavirus.
Delhi has third-highest number of infections in India with over 42,800 cases and 1,400 fatalities till date.
