Scientists warn of new Covid variant with high number of mutations
The B.1.1.529 variant was first spotted in Botswana and six cases have been found in South Africa
Scientists have said a new Covid variant that carries an “extremely high number” of mutations may drive further waves of disease by evading the body’s defences.
Only 10 cases in three countries have been confirmed by genomic sequencing, but the variant has sparked serious concern among some researchers because a number of the mutations may help the virus evade immunity.
