Experts said the Omicron wave would not cause many deaths or hospitalisations, but several states imposed restrictions on movement and have only now started easing them.

Authorities in the Delhi area that includes the capital on Friday announced high schools, colleges, restaurants and gyms would be allowed to open from next week.

After being shut for almost two years, first because of coronavirus and then again for pollution following a brief reopening, in-person classes for four- to 14-year-olds will restart on February 14, Delhi’s deputy chief minister Manish Sisodia tweeted.

India was hit by a devastating spike in cases last year due to the Delta variant that brought its health care system close to collapse.

Many analysts believe the country actually may have reached the 500,000-death mark last year itself.

The wave saw at least 200,000 deaths as hospitals ran out of oxygen and patients scrambled desperately to source medicines.

A study by a US research group last year suggested that anywhere between 3.4 million and 4.7 million people had died.

For months now, several states have been reconciling their death toll and adding “backlog” deaths as India’s Supreme Court ordered state authorities to provide compensation to families.

Kerala, Bihar and Prime Minister Narendra Modi’s home state of Gujarat are among those to have added thousands of old deaths to their existing tolls.

Last month, the Modi government asked states to stop mandatory testing of contacts of those who test positive, unless they had underlying health conditions.

But soon after the order the government told states to ramp up testing as numbers dropped.

Booming sales of home coronavirus self-test kits have also fuelled fears of underreporting of cases across the country.
