All DMs and civil surgeons have been asked to do so. Request private hospitals to assist and support.There have been fears of a spike in COVID 19 cases in the state, so far moderately affected by the calamity yet proactive in taking preventive measures, in the wake of return of a large number of migrants from other parts of the country after the nationwide lockdown was imposed.
