This variant was first detected in Mpumalanga and Gauteng provinces in May, when South Africa was about to enter the third wave. As of August 13, variant C.1.2 had appeared in 7/9 provinces in South Africa. and many other countries in Africa, Europe, Asia and Oceania.
The South African Ministry of Health’s deputy director-general in charge of expertise Anban Pillay said this variant only accounts for a very small part of the current testing samples but is increasing month by month, similar to the beginning of the pandemic. Beta or Delta variants.
According to the researchers, the available data likely do not reflect the true extent of C.1.2’s spread in South Africa and around the world. One of the study’s authors, Cathrine Scheepers, said the new variant likely emerged after a prolonged wave of Covid-19 infections and accumulated additional mutations that could help escape the immune response. .
According to the research, C.1.2 has 59 variations compared to the first Covid-19 variant discovered in Wuhan (China). Scientists said that C.1.2 has not been classified as a variant of concern like Delta, Alpha, Beta, Gamma but can be classified as a variant of concern.
Meanwhile, a research team, led by Professor Takeuchi Hiroaki at Tokyo Medical University Hospital, has just announced the results of a new study on August 30, saying it has discovered for the first time a new mutation of the variable. Delta body in this country. The new mutation was discovered in a patient with the Delta variant who visited the aforementioned hospital in mid-August.
Genetic analysis revealed a mutation of the Delta variant, known as N501S, and there are currently only eight cases of this mutation reported outside of Japan. The team says the N501S mutation resembles the Alpha variant’s N501Y mutation, which was first discovered in the UK. The team added that it is not yet clear whether the new mutation affects the spread of the Delta variant, so they plan to do more research.
