Omicron BA.2 becomes dominant covid variant in India

New Delhi, Feb 23: A new sibling of the Omicron variant of SARS-CoV-2 has taken over the Indian Covid-19 landscape over the past month without altering the epidemic's waning course, even as the World Health Organization described it as a distinct variant of concern.

A technical advisory group of the WHO on Tuesday declared BA.2 sub-lineage of Omicron as a “variant of concern” on the basis of available data on transmission, severity, reinfection, diagnostics, therapeutics and impacts of vaccines.

“Studies have shown that BA.2 has a growth advantage over BA.1. Studies are ongoing to understand the reasons for this growth advantage, but initial data suggest that BA.2 appears inherently more transmissible than BA.1, which currently remains the most common Omicron sublineage reported,” the apex health body said.

But BA.2 has already become the dominant variant circulating in India.

Indian scientists monitoring the Covid-19 epidemic said more than 80 per cent of the Covid-19 positive samples sequenced in the past four weeks turned out to be BA.2.

In Pune, BA.2 was over 85 per cent by the last week of January, but cases continue to drop, suggesting protection from BA.1 infections and vaccination gave reasonable results in securing people from developing the disease, said a scientist associated with Covid genome sequencing work.

The WHO concurs. “Initial data from population-level reinfection studies suggest that infection with BA.1 provides strong protection against reinfection with BA.2, at least for the limited period for which data are available,” the UN body said.

The Pune scientist cautioned that it was preliminary evidence and the new variant needed to be observed closely.

BA.2 differs from BA.1 in its genetic sequence, including some amino acid differences in the spike protein and other proteins.

Omicron is currently the dominant variant circulating globally, accounting for nearly all sequences reported to GISAID, an international database of genetic sequences. At a global level, the proportion of BA.2 sequences has been increasing relative to BA.1 in recent weeks. However, the global circulation of all variants is declining, as per the WHO.

Udupi, Dec 15: What was meant to be a post-pilgrimage gathering turned tragic in Padukere village of Brahmavar taluk, Udupi district, late Sunday night, when a clash among youths escalated into a fatal assault, leaving one man dead.

The victim has been identified as 30-year-old Santosh Mogaveera, a resident of Padukere.

According to preliminary information, the incident took place during a late-night drinking party involving a group of local youths who had recently returned after completing their pilgrimage to the Sabarimala shrine. An argument reportedly broke out among the group and soon escalated into a violent confrontation.

During the ensuing brawl, Santosh Mogaveera was allegedly assaulted and collapsed at the spot after sustaining serious injuries. He was rushed by local residents to a private hospital in Brahmavar, where doctors declared him dead.

On receiving information, senior police officials, including Brahmavar Circle Inspector Gopikrishna, Kota Police Sub-Inspector Praveen Kumar T, Station ASI Manthesh Jabagoudar, and head constables Pradeep and Ashok, visited the spot and conducted an inspection.

Police have taken four youths into custody in connection with the incident. A case has been registered at the Kota police station, and further investigation is underway to ascertain the exact sequence of events leading to the death.

Mangaluru, Dec 3: A group of Congress workers gathered at the Mangaluru International Airport on Wednesday to welcome AICC general secretary K C Venugopal, but the reception quickly turned into a display of support for Deputy Chief Minister D K Shivakumar.

Venugopal arrived in the city to participate in the centenary commemoration of the historic dialogue between Mahatma Gandhi and Narayana Guru. The event, organised by the Sivagiri Mutt, Varkala, in association with the Mangalore University Sri Narayana Guru Study Chair, is being held on the university’s Konaje campus.

KPCC general secretary Mithun Rai and several party workers had assembled at the airport to receive Venugopal. However, the moment he stepped out, workers began raising slogans backing Shivakumar.

The university programme will be inaugurated by Chief Minister Siddaramaiah.

This show of support comes just a day after Siddaramaiah remarked that Shivakumar would lead the government “when the high command decides.” The chief minister made the comment after a breakfast meeting at Shivakumar’s residence—another public display of camaraderie between the two leaders amid ongoing attempts by the party high command to downplay their leadership rivalry.

New Delhi: School-going children are picking up drug and smoking habits and engaging in consumption of alcohol, with the average age of introduction to such harmful substances found to be around 13 years, suggesting a need for earlier interventions as early as primary school, a multi-city survey by AIIMS-Delhi said.

The findings also showed substance use increased in higher grades, with grade XI/XII students two times more likely to report use of substances when compared with grade VIII students. This emphasised the importance of continued prevention and intervention through middle and high school.

The study led by Dr Anju Dhawan of AIIMS's National Drug Dependence Treatment Centre, published in the National Medical Journal of India this month, looks at adolescent substance use across diverse regions.

The survey included 5,920 students from classes 8, 9, 11 and 12 in urban government, private and rural schools across 10 cities -- Bengaluru, Chandigarh, Delhi, Dibrugarh, Hyderabad, Imphal, Jammu, Lucknow, Mumbai, and Ranchi. The data were collected between May 2018 and June 2019.

The average age of initiation for any substance was 12.9 (2.8) years. It was lowest for inhalants (11.3 years) followed by heroin (12.3 years) and opioid pharmaceuticals (without prescription; 12.5 years).

Overall, 15.1 per cent of participants reported lifetime use, 10.3 per cent reported past year use, and 7.2 per cent reported use in the past month of any substance, the study found.

The most common substances used in the past year, after tobacco (4 per cent) and alcohol (3.8 per cent), were opioids (2.8 per cent), followed by cannabis (2 per cent) and inhalants (1.9 per cent). Use of non-prescribed pharmaceutical opioids was most common among opioid users (90.2 per cent).

On being asked, 'Do you think this substance is easily available for a person of your age' separately for each substance category, nearly half the students (46.3 per cent) endorsed that tobacco products and more than one-third of the students (36.5 per cent) agreed that a person of their age can easily procure alcohol products.

Similarly, for Bhang (21.9 per cent), ganja/charas (16.1 per cent), inhalants (15.2 per cent), sedatives (13.7 per cent), opium and heroin (10 per cent each), the students endorsed that these can be easily procured.

About 95 per cent of the children, irrespective of their grade, agreed with the statement that 'drug use is harmful'.

The rates of substance use (any) among boys were significantly higher than those of girls for substance use (ever), use in the past year and use in the past 30 days. Compared to grade VIII students, grade IX students were more likely, and grade XI/XII students were twice as likely to have used any substance (ever).

The likelihood of past-year use of any substance was also higher for grade IX students and for grade XI/XII students as compared to grade VIII students.

About 40 per cent of students mentioned that they had a family member who used tobacco or alcohol each. The use of cannabis (any product) and opioid (any product) by a family member was reported by 8.2 per cent and 3.9 per cent of students, respectively, while the use of other substances, such as inhalants/sedatives by family was 2-3 per cent, the study found.

A relatively smaller percentage of students reported use of tobacco or alcohol among peers as compared to among family members, while a higher percentage reported inhalants, sedatives, cannabis or opioid use among peers.

Children using substances (past year) compared to non-users reported significantly higher any substance use by their family members and peers.

There were 25.7 per cent students who replied 'yes' to the question 'conflicts/fights often occur in your family'. Most students also replied affirmatively to 'family members are aware of how their time is being spent' and 'damily members are aware of with whom they spend their time'.
