Meanwhile, more than 130 final year MBBS students were appointed on Friday to man control rooms in zones. “The students will contact persons under home quarantine every day to track their health. They will also suggest proper medication. At present, around 30,000 people are under home quarantine. More than 3,700 non-oxygen beds are empty in COVID care centres and people should come here if they do not have facilities at home,” Bedi said.
