India will not reach its coronavirus peak until mid-November, according to researchers from the Indian Council of Medical Research, as New Delhi plans to convert train carriages into isolation wards.
A new lockdown also looms for 15 million people in the city of Chennai.
After a surge in infections, some hospitals in New Delhi were unable to admit coronavirus-positive patients as they had run out of beds, despite fewer than 40,000 cases being recorded.
India's capital has only 9816 dedicated beds for coronavirus patients but Manish Sisodia, its deputy chief minister, has warned that 500,000 people will be infected by July 31.
The Indian Government has now stepped in to convert 500 train carriages into isolation wards in New Delhi for around 8000 people.
