India on Thursday recorded 16,922 new cases of Covid-19 in the last 24 hours – highest so far- pushing the nationwide tally to 4,73,105.

According to Union health ministry’s update at 8 am, the number of active cases in the country are 1,86,514. The country also saw 418 deaths in the last 24 hours, which pushed its death toll to 14,894.

Delhi, which already is the second worst hit state in terms of coronavirus caseload and fatalities, overtook Mumbai after the number of cases soared by 3,788 to touch 70,390. Mumbai has so far recorded 69,625 cases, according to official figures.

As part of the Delhi government’s revised Covid-19 response plan, a house to house screening will be completed by June 30 in containment zones and for the rest of the city by July 6 in what is billed as a mammoth exercise.

In all, 12 states now account for more than 10,000 coronavirus cases as they continued to report record daily spikes that were mainly attributed to augmented testing.
