Covid has evolved; over the past couple of years, we’ve seen several sub-variants. One of its variants is the Omicron, first reported in South Africa on 24 November 2021 by the Network for Genomics Surveillance. It is a contagious infection with a very high mutation rate and transmissibility. However, the Omicron variant has comparatively milder symptoms. Omicron BF 7 and BA.5.1.7 are its new sub-variants.
Recently a new subvariant of Omicron- BF.7 has become the cause of rapidly spreading COVID infections in China.
As per a recent study, the researchers have discovered enhanced neutralization resistance in all new sub-variants of the Omicron strain. The most recent variant, BF.7, which is wreaking havoc in China, has a much higher neutralization resistance than the original COVID-19. This new strain can dodge the immunity build and antibodies created from previous vaccinations and infection.
We already know that the mutant variant of a virus has an advantage over the wild-type virus. The same is the case for Omicron BF.7.
BF.7 also has immune-evasive characteristics and is fast-mutating, making it more virulent. People who still need to take the vaccinations are at high risk. Also, elderly citizens, children, people with multiple co-morbidities and pregnant females are more susceptible to infection.
The symptoms of BF.7 infection are similar to those associated with other Omicron sub-variants. It primarily causes upper respiratory symptoms. Infected patients have -
Some patients might also experience gastrointestinal symptoms like vomiting and diarrhea.
To help prevent complications from the subvariant and curb its transmission, it is recommended that we all wear masks in crowded places and practice social distancing. In addition to that, getting vaccinated is also highly recommended. Vaccinated people must also get their booster dose in time.
The Indian Medical Association has alerted the public about the new variant – Omicron BF.7 and also appealed to everyone to follow COVID appropriate behavior. Here are some of the recommended guidelines:
Remember, the most important thing is to take all the necessary precautions and maintain distance from people who have symptoms like cough, fever and sore throat.
