As returning migrants and easing lockdown push the coronavirus far and wide, an analysis of statewise data shows that when it comes to Covid patients requiring critical care, their share, even in high-burden states like Maharashtra, Delhi, Gujarat and Tamil Nadu, remains low. So is the demand for ventilators. Similar is the case in states like Bihar, Jharkhand, Chhattisgarh and Odisha where the migrant influx is pushing up Covid numbers. Of the total 83,004 active cases on May 27, less than 3500 needed any kind of intervention — oxygen therapy, ICU or ventilators.A total of 1,868 patients needed ICU (2.25 per cent), of whom just three were on ventilators while 1585 people (1.91 per cent) were on oxygen. This trend has remained largely unchanged since the first cases came in.
