The most mutated variant of the coronavirus yet was found in travellers from Tanzania. A report submitted to the World Health Organization and regional bodies shows the strain has 10 more mutations than found on any other version, according to Tulio de Oliveira, director of Krisp, a scientific institute that carries out genetic testing for 10 African nations.
Krisp, which discovered a new strain in South Africa last year that propelled a resurgence of infections in the country, found the new variant in travellers arriving in Angola from Tanzania.
