The death of seven persons on a single day at a hospital in Palghar district sparked anger among relatives over the alleged short supply of oxygen cylinders and administrative failure at the facility amid the rampaging Covid-19 crisis in Maharashtra. The fatalities -- all reported from the intensive care unit -- may also be indicative of the larger crisis gripping the Vasai-Virar Municipal Corporation under whose jurisdiction the Nala Sopara hospital falls. Officials at the tertiary care centre, however, have said the patients were already in critical condition at the time of admission.
