New Covid variant C.1.2 will be more dangerous

A new variant of SARS-CoV-2, the virus which cause COVID-19, has been detected in South Africa and many other countries globally which could be more transmissible and evade protection provided by vaccines, according to study.

Scientists from 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 first detected in the country in May this year. C.1.2 has since been found in China, the Democratic Republic of the Congo, Mauritius, England, New Zealand, Portugal and Switzerland as of August 13, they said.

According to the yet-to-be peer-reviewed study posted on the preprint repository MedRxiv on August 24, C.1.2 has mutated substantially compared to C.1, one of the lineages which dominated the SARS-CoV-2 infections in the first wave in South Africa.
