The doctor was infected by a woman, who had a travel history to Saudi Arabia and visited him on March 12 after developing COVID-19 symptoms.
The doctor's wife and his teen daughter have also tested positive.
Five members of woman's family contracted the virus
The woman returned on March 10 and as many as five people from her family got infected. This includes her mother, her brother, two daughters aged more than 20, and a relative who picked her from the airport.
Five days after her visit to the clinic in Maujpur area, the woman tested positive.
That day, the doctor was admitted to a hospital too.
The doctor developed breathing problems
Between March 12 and 17, the doctor continued to treat patients, probably oblivious to the fact that he had been infected too.
Initially, the doctor was taken to GTB Hospital but after he complained of breathing problems, he had to be shifted to Safdarjung Hospital on Monday night, a TOI report said.
He was shifted to an isolation room after being stable.
