NEW DELHI--India’s coronavirus cases surged to 4.2 million, the second-highest total in the world, on Monday as urban metro trains partially resume service in the capital New Delhi and other states.

The 90,802 cases added in the past 24 hours pushed India’s total to 4,204,614, passing Brazil, which has more than 4.1 million, according to a tally by Johns Hopkins University. More than 6.2 million people in the United States have been infected.

India’s Health Ministry on Monday also reported 1,016 deaths from COVID-19 in the past 24 hours, taking fatalities to 71,642, the third-highest national death toll.

Amid a surge in cases, India continues to reopen, except in high-risk areas, to heal the battered economy which is still reeling from the effects of a prolonged lockdown.

The Delhi Metro transit system that serves India’s sprawling capital New Delhi and adjoining areas resumed operations Monday after five months. Masks, social distancing and temperature checks were mandatory.

India says it is now conducting 1 million tests daily, but the virus is reaching cities and towns previously spared, offsetting marginal declines in some states.

India has been recording the world’s largest daily coronavirus caseload for almost a month even as the government pushes to open businesses to revive a contracting economy.
