Covid-19 in India: Omicron is in Community Transmission

Omicron is more infectious than the Delta variant. Now, Omicron variant is in community transmission stage in India.

In India, the Omicron variant is now in community transmission stage, said the Indian SARS-CoV-2 Genomics Consortium (INSACOG), as the variant is becoming dominant in many countries. //

The center's genome sequencing body has also said that an infectious sub-variant of Omicron BA.2 lineage has been reported in a considerable fraction in India.

Why Does Omicron Variant Spread Faster?
Omicron variant's increased transmissibility is due to immune evasion. In many countries, Omicron has rapidly surged past other variants to become the dominant SARS-CoV-2 strain.

‘The best way to fight Covid-19 is through prevention with vaccination and maintaining hand and respiratory hygiene.’

Talking to IANS, Dr Niraj Nischal, Additional Professor of Medicine, AIIMS, said: "Omicron is more infectious compared to Delta variant, but it has a survival advantage as it is not causing severe illness among masses as delta did. The variant has more transmissibility but without leading to serious problems for majority of individuals.

"In due course, the variants are replaced always like Delta replaced the earlier variant and the Delta is expected to be replaced by Omicron."

However, he also added that it doesn't create any differences for masses as the treatment protocol remains the same. He said that genome sequencing is done only for public health management perspective to monitor for emergence of new dangerous variants as the treatment protocol is same for all variants so far.

Protection Against the Omicron Variant by N95 and Cotton Masks
Cotton masks, especially N95 masks, remain effective in protecting people from COVID-19. Let’s take a quick look at right masks that can help keep Omicron at bay and what are the effective mask-wearing measures that needs to be followed.

The INSACOG has said that while most Omicron cases so far have been asymptomatic or mild, hospitalizations and ICU cases have been increasing in the current wave, and the threat level remains unchanged. "The recently reported B.1.640.2 lineage is being monitored. There is no evidence of rapid spread and while it has features of immune escape, it is currently not a variant of concern. So far, no case detected in India", the bulletin said.

Dr Anshuman Kumar, a Delhi-based cancer specialist, said: "Declaring the community transmission helps in strategy making to curb the infections. Community transmission is defined as the index virus infection is detected majorly in the individuals who don't have any travel history or any contact with the infected persons."

Omicron Now in 171 Countries: WHO
In 171 countries, the Omicron variant of COVID-19 has been discovered, said the World Health Organization (WHO). The global health body said that Omicron is soon set to replace Delta globally as a result of its immunity evading potential.

However, terming the Omicron community transmission declaration as illogical, Dr Kumar told IANS that there is no point to declare Omicron community transmission at this stage of time when the variant has already replaced the Delta variant in the country by over 80 percent.

He said that if such declarations are made beforehand, the government gets time to make strategy and extensive planning to curb the rising infection, said Dr Kumar.

New 'variant Under Investigation' of Omicron Identified!
New strain of omicron — BA.2 is classified as a 'variant under investigation' as cases are confirmed in Britain.

"Consider all cases Omicron now unless it is proved otherwise. If patient has lung symptoms or reducing oxygen levels, then it should be sent for genome sequencing to check whether it is Delta variant because Omicron infection is common now," he said.

Dr Abhishek Shankar, Associate Professor, Department of Radiation Oncology, AIIMS Patna, said: "Omicron has already achieved peak in many of the states in India and they are on the path of recovery. India being a large country has always witnessed variation in the Covid statistics in different states. We have already seen the different timing of peak of 1st and 2nd wave in different states and 3rd wave is not an exception."

He added that unlike Delta wave, we are not expecting the fourth stage of pandemic for Omicron in view of affecting upper respiratory tract only. "Prevention with vaccination and maintaining hand and respiratory hygiene will be our best stand to fight Covid," he said.
