New Delhi, August 9 Omicron’s globally dominant BA.5 variant is also growing in India; and contributing to nearly 20-30% of new reported cases. The surge in BA.5 variants comes even as parts of the country, such as Delhi, are experiencing a spike in Covid-19 positivity. There was, however, no decision on the mix of vaccines (for the booster), a senior official from the Union Department of Health and Family Welfare said. Activity area.
According to the official, the BA.5 variants accounted for about 10-15% of the total Covid cases reported about two to three weeks ago in India. However, at present, the number has increased by 2 to 3 times.
The spike, however, is “less worrying” as there were “no clusters” of infection reported from anywhere in the country.
“At present, BA.2 variants continue to be the dominant strain, accounting for 70-80% of total Covid cases. These will include sublines such as 2.38, 2.73, 2.74, and 2.75. However, BA.5 cases are now on the rise. They are almost double what they were 14 to 21 days ago. This too is seen as a cause of breakthrough infections,” the official said.
Genome sequencing data has yet to reveal a “concerning variant”. Insacog will meet on Friday to resume discussions on the Covid data and decide on the future way forward, if necessary.
“Unlike Western countries, there is no report of clustering caused by BA.5,” the official said.
The BA.5 variant has three key mutations in its spike protein, which increase the chances of infection and the ability to override immune defenses. In just over two months, BA.5 has become the leading cause of Covid-19 in the United States. Last week, this subvariant caused nearly two out of three new Covid-19 infections in the United States, according to CDC data.
In India, according to the latest Insacog report, Omicron and its sublines continue to be the dominant variant. Omicron BA.2 and BA.2.38 sublines have mostly been found and “some BA.2.75 have been identified”. However, no increase in hospitalizations or severity of illness was observed.
According to the official, the Center has yet to respond to a call about mixing the vaccines.
The biological protein E subunit Corbevax (Covid-19 vaccine) was the first to be approved by the country’s drug regulatory body or DGCI as a heterologous booster in adults, meaning those who received Covishield or Covaxin as a first or second dose can take it as a third booster shot.
“The Center needs to take a call and it’s on hold,” he said.
