According to the study, a new variant of SARS-CoV-2, the virus that causes COVID-19, has been detected in South Africa and several other countries globally, which is likely to evade the protection and defenses provided by vaccines. Could be.
Scientists from the National Institute for Communicable Diseases (NICD) and the KwaZulu-Natal Research Innovation and Sequencing Platform (KRISP) in South Africa said the potential variant of interest, C.1.2, was detected for the first time in the country in May this year. C.1.2 has since been detected in China, the Democratic Republic of the Congo, Mauritius, England, New Zealand, Portugal and Switzerland as of August 13, he said. According to a peer-reviewed study posted on the preprint repository MedRxiv on August 24, C.1.2 mutated to a greater extent than C.1, in a lineage previously dominated by SARS-CoV-2 infections is one of. Wave in South Africa.
The new variant has more mutations than other forms of anxiety (VOC) or forms of interest (VOIs), which have so far been found worldwide, the researchers said. They noted that the number of available sequences of C.1.2 may be an underrepresentation of the prevalence and frequency of variation in South Africa and around the world. The study found that South Africa had a steady increase in the number of C.1.2 genomes each month, from 0.2 percent of sequenced genomes in May to 1.6 percent in June and then to 2 percent in July. “This is similar to the increase seen with beta and delta variants in the country during early detection,” the study authors said.
