The fourth phase of the coronavirus-triggered lockdown, which began on May 18, saw 85,974 Covid-19 cases till 8am on Sunday, which is nearly half of the total cases reported in the country so far.

Lockdown 4.0, which will end on May 31 midnight, has accounted for 47.20 per cent of the total coronavirus infection cases, number crunching from the Union health ministry data reveals.

The lockdown, which was first clamped on March 25 and spanned for 21 days, had registered 10,877 cases, while the second phase of the curbs that began on April 15 and stretched for 19 days till May 3, saw 31,094 cases.

The third phase of the lockdown that was in effect for 14 days ending on May 17, recorded 53,636 cases till 8am of May 18.

The country had registered 512 coronavirus infection cases till March 24.

India is the ninth worst-hit nation by the Covid-19 pandemic as of now.

The first case of Covid-19 in India was reported on January 30 from Kerala after a medical student of Wuhan university, who had returned to India, tested positive for the virus.

India registered its highest single-day spike of Covid-19 cases on Sunday, with 8,380 new infections reported in the last 24 hours, taking the country's tally to 1,82,143, while the death toll rose to 5,164, according to the Union health ministry.

The number of active Covid-19 cases stood to 89,995, while 86,983 people have recovered and one patient has migrated, it said.

'Thus, around 47.75 per cent patients have recovered so far,' a senior health ministry official said.

With the fourth phase of lockdown ending on Sunday, the home ministry on Saturday said 'Unlock-1' will be initiated in the country from June 8 under which the nationwide lockdown will be relaxed to a great extent, including opening of shopping malls, restaurants and religious places, even as strict restrictions will remain in place till June 30 in the country's worst-hit areas.

While announcing the extension of the lockdown in containment zones across the country, the home ministry said temples, mosques, churches and other religious places and shopping malls will be allowed to open in a phased manner from June 8, while a decision on opening of schools and colleges will be taken in July in consultation with states.
