- Dr NK Arora warned rapid change in Omicron sublineage in future
- Dr Arora has advised to take precautionary COVID vaccine doses
- Hybrid immunity is helping subside the severity of COVID-19: Dr. Arora
New Delhi: Dr NK Arora, Chairman of the COVID working group, National Technical Advisory Group on Immunisation (NTAGI), on Wednesday said that COVID-19 is still around us and quite a significant transmission of viruses is going on. In an exclusive interview with ANI Dr NK Arora Chairperson COVID working group, NTAGI said, “COVID is very much around us and there is quite a significant transmission of viruses going on at the moment in the country. Although we don’t see the severe form of COVID, it is very much around.”

Dr Arora further warned that the rapid change in Omicron sublineage is circulating.
During the last four or five months, we are rapidly seeing two or three changes in the genomic profile of viruses. So we started with BA.1 and then BA.2 and later on a lot of sub-lineage of BA.2 overtook. Somewhere in April, BA.4 and BA.5 also came and now we find during the last two weeks BA.2.75 is the dominant lineage which is circulating
He said that the hybrid immunity of vaccines and exposure naturally to viruses is helping to see that the disease severity is mild. He explained,
There is a rapid change in sub-lineage which is circulating in the country. Now on one side when we look at the clinical behaviour of these viruses, and the severity profile, it is not. So, overall, we feel that currently whatever virus is circulating it is not able to cause severe disease. And there are two important things in this direction. One is that most of the adult population is immunised at the moment. And the second is that most of the population has already been exposed naturally. So this hybrid immunity is helping us to see that the disease severity is mild
He said that during the last seven-eight months no new virus which is causing severe disease has emerged. Dr. Arora added,
However, based on this experience, and also when I look at the first quarter of 2021 when initially we had similar kinds of several types of viruses circulating and suddenly data virus came up. For the last seven-eight months no new virus which is causing severe disease has emerged. In addition, we have also got immunisation so it looks unlikely that there will be any virus, which will cause severe disease but we need to be cautious at least for a few more months

Emphasising further on COVID-appropriate behaviour, Dr Arora also said that the COVID virus is going to stay with us but people need to be careful and be disciplined some more time. He also advised everyone to take precautionary doses as human antibodies decrease after 6-8 months. On taking precaution dose, Dr Arora said,
Two pieces of information I will give to all. One is when we take a vaccine, booster doses will act as insurance for our health in the future. That means if in case a virus comes which can cause severe disease and if one has to protect themselves then he/she must take a precautionary dose because almost everybody who has received two doses, it is more than six months. So precaution dose is important

According to the data, he said, in the last eight months, 90 per cent of patients admitted to hospitals have not received booster doses. He added,
The second is that whatever information we are getting from the whole country, those who are hospitalised with COVID at the moment, mostly they have comorbidities, but the important point is that most of these individuals have not taken precaution dose, which means there is a possibility that if these people had taken precaution dose, then risk of becoming severe disease was less likely
Meanwhile, India on Wednesday reported 7,231 new COVID-19 cases in the last 24 hours, taking the active caseload below 65,000 mark, according to the Union Health Ministry data. Currently, the country has 64,667 active cases.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
