''So far, 51 people, including 48 students and three staff members, from the Jawahar Navodaya Vidyalaya have tested positive for coronavirus. All of them have been isolated and hospitalised. Most of the students are asymptomatic and their health is stable,'' the official said.

Ahmednagar district collector Rajendra Bhosale said the school campus has been declared a 'containment zone'.

''I visited the school today. As a precautionary measure, we have deployed a medical team comprising a doctor and two nurses to monitor other students in the campus (in case they develop any symptoms),'' he said.
