The new confirmed cases took the national total to 820,916. The health ministry has also reported another 519 deaths for a total of 22,123.

A surge in infections saw the cases jumping from 600,000 to more than 800,000 in nine days. The ministry said the recovery rate was continuing to improve at more than 62 per cent.

Eight of India's 28 states, including the worst-hit Maharashtra, Tamil Nadu and New Delhi, account for nearly 90pc of all infections.
