Brazil, which had overtaken India last month to become the world's second most infected country, has slightly over 13.48 million cases, according to the same tally.
India is in the throes of a second virus surge, and reported around 168,900 new daily cases on Monday, far surpassing the September peak in its first surge, Kyodo News reported.
The government is calling on the public to continue wearing masks and observing social distancing measures while seeking to vaccinate its population.
But in a country of over 1.3 billion people, demand far outstrips supply. AFP reported that hospitals across the nation say they are being overwhelmed by the new cases, and daily deaths have more than doubled.
"There is no alternative now to this in order to curb the Covid-19 surge," junior minister Farhad Hossain said ahead of the clampdown announcement.
