Recently a new sub-variant of Omicron virus BA-2.75 was discovered in Delhi, India. This sub-variant was detected during a genome sequencing of 90 samples. The fact was confirmed by an official (Dr Suresh Kumar, Medical Director at LNJP Hospital) on news agency ANI on Wednesday.
Higher transmission rate:
The official confirmed that the new sub-variant BA-2.75 has a higher transmission rate. This sub-variant can also affect people who are previously vaccinated with the COVID vaccine and people having antibodies.
According to World Health Organisation (WHO), the new sub-variant BA-2.75 might not be as serious as the delta or the parent Omicron virus. However, there is no evidence to support it.
At present, the number of people affected with the new sub-variant BA-2.75 is relatively low.
There are studies to support the statement of Dr Suresh Kumar on the transmission of the new sub-variant BA-2.75, which also state that the new sub-variant BA-2.75 has a higher resistance to antibodies developed from the BA.5 sub-variant. BA.5 is the dominant strain in many countries.
As per Eric Topol, the new sub-variant BA-2.75 does not show superior immune evading properties over BA.5 sub-variant. Moreover, it has modest resistance to Bebtelovimab (monoclonal antibody) and has a higher receptor binding affinity than other variants of Omicron.
The threat of the new sub-variant BA-2.75:
It is unclear if the new variant is a potential threat. Some consider it a potential threat due to its superior immune evading properties over BA.5 sub-variant, while others refuse it. Hence experts recommend following the precautionary measures to prevent the spread of the Omicron virus.
Wear face mask
Follow proper hygiene
Avoid crowded places
Self-isolation in case of any symptoms of the infection
