This new variant, B.1.1.529 seems to spread very quick! In less than 2 weeks now dominates all infections following a devastating Delta wave in South Africa (Blue new variant, now at 75% of last genomes and soon to reach 100%) /Z9mde45Qe0- Tulio de Oliveira November 25, 2021 Early PCR test results showed that 90% of 1,100 new cases reported Wednesday in the South African province that includes Johannesburg were caused by the new variant, according to Tulio de Oliveira, a bio-informatics professor who runs gene-sequencing institutions at two South African universities. The beta variant, a mutation identified last year in South Africa, also may have come from an HIV-infected person.Īs of Thursday there were almost 100 cases detected in South Africa, where it's become the dominant strain among new infections. South Africa has 8.2 million people infected with HIV, the most in the world. One scientist at the UCL Genetics Institute in London said it likely evolved during a chronic infection of an immuno-compromised person, possibly in an untreated HIV/AIDS patient. Researchers are still trying to determine whether it is more transmissible or more lethal than previous ones. Scientists say B.1.1.529 carries a high number of mutations in its spike protein, which plays a key role in the virus' entry into cells in the body. Fears a new strain could fuel outbreaks in many countries, straining health systems, potentially evading vaccines and complicating efforts to reopen economies and borders, sent a wave of risk aversion across global markets Friday. A new variant of the coronavirus - called B.1.1.529 - has been identified in South Africa, with officials there saying it's of concern.
