A new sub-lineage BA.2.75 of the Omicron variant of the coronavirus has been detected in countries like India and the World Health Organisation is following this as informed by Director-General Tedros Adhanom Ghebreyesus.
On COVID-19, globally reported cases have increased nearly 30 per cent over the past two weeks. Four out of six of the WHO sub-regions saw cases increase in the last week. In Europe and America, BA.4 and BA.5 are driving waves. In countries like India a new sub-lineage of BA.2.75 has also been detected, which we’re following.
On the emergence of the potential Omicron sub-variant BA.2.75, WHO Chief Scientist Soumya Swaminathan said in a video posted on Twitter that there has been an emergence of a sub-variant that is being called the BA.2.75 first reported from India and then from about 10 other countries.
She said there are still limited sequences available of the sub-variant to analyse, but this sub-variant seems to have a few mutations on the receptor-binding domain of the spike protein. So obviously, that’s a key part of the virus that attaches itself to the human receptor. So we have to watch that. It’s still too early to know if this sub-variant has properties of additional immune evasion or indeed of being more clinically severe. We don’t know that.”
The WHO weekly epidemiological update on COVID-19, released July 6, said that globally, the number of new weekly cases increased for the fourth consecutive week after a declining trend since the last peak in March 2022.
During the week of June 27 to July 3, over 4.6 million cases were reported, a figure similar to that of the previous week. The number of new weekly deaths declined by 12% as compared to the previous week, with over 8100 fatalities reported. As of July 3, 2022, over 546 million confirmed COVID19 cases and over 6.3 million deaths had been reported globally.
