Army personnel have decontaminated the premises of Command Hospital in the city and identified those that came in contact with a doctor there who have tested positive for COVID-19, an official statement said here on Monday.
People found to have come in direct contact with the doctor were relocated to a separate quarantine facility with full medical and administration support, it said.
The army doctor, who had travelled to Delhi between March 12 and 17 and participated in professional discussions in the national capital, had tested positive for COVID-19 at the Eastern Command Hospital on March 29.
"In a swift response, Indian Army teams quickly isolated the facility and identified the direct contacts of the doctor in Kolkata," the statement said.
The workplace and the premises of the Command Hospital have been decontaminated with three teams working overnight, it said.
The statement also said that further actions were in progress to establish contact with those who might have come in close proximity of the doctor, while he was at the national capital and during transit.
"All actions will be taken to proactively contain the issue," it added.
