Omicron variant may be less lethal in India, epidemiologist says

The newly-emerged omicron variant is likely to be less lethal in India than the delta-led virus wave that overwhelmed hospitals and crematoriums earlier this year, according to a prominent epidemiologist.

Given the widespread exposure of Indians to Covid-19 virus and a reasonably-high vaccination rate, India will likely be less affected by the new strain, Ramanan Laxminarayan, director of the Center for Disease Dynamics, Economics & Policy said in an interview with Bloomberg Television on Thursday. That may change if omicron is effective at getting past all immune defenses, he said.

As omicron -- first detected in South Africa late last month -- appears to cause mild infections, “the damage in terms of hospitalization and stress on the health system will be less than what we have seen in the second wave,” Laxminarayan said. Australia’s Chief Medical Officer Paul Kelly has also said that there is no indication that the omicron is deadlier than other strains.

India saw the world’s fastest-surging Covid outbreak in early-May with daily new infections exceeding 400,000 when the highly-infectious delta variant was ripping through the crowded nation of 1.4 billion people. The deadly virus wave invigorated the country’s vaccination campaign -- more than a billion shots have been administered already -- and created high levels of natural immunity in the population.

More than two-thirds of India’s population had antibodies against Covid-19, a national serological survey found in a study in June and July. About 48.5% of India’s adult population is fully vaccinated with two doses, according the Health Ministry data.

So far, India has detected two cases of the omicron variant - both in Karnataka.

At least ten passengers traveling from “at risk” countries tested positive and their samples have been sent for genome sequencing, the government said. India has bolstered its genome sequencing efforts and tightened travel rules.

The emergence and rapid spread of the new variant in other countries may bolster India’s inoculation program, according to Laxminarayan. It may prod some reluctant people to get vaccinated and others to return for their second dose.
