Contact tracing was immediately initiated and samples of these 40 healthcare workers along with some patients from the ward where the nurse was posted were sent for testing.

“Test results of around 22 people have come out which includes the results of four ICU patients. They are negative. Results of the rest are awaited,” a doctor said.

According to the doctor, the nurse had fever on Saturday and had approached the doctors on phone in the clinic for AIIMS’ employees the same evening. He was advised to come for testing on Monday.
