What is the Delta variant of Covid-19?
Multiple SARS-CoV-2 variants are circulating globally. One of these is the B.1.617 lineage, detected in India earlier this year. Early evidence suggests that its sub-lineage B.1.617.2, known as the Delta variant, is more transmissible than contemporary lineages.
The World Health Organizaton (WHO), which has given it the label Delta, has categorised it as a variant of concern (VOC). It has said it continues to observe “significantly increased transmissibility” and a “growing number of countries reporting outbreaks associated with this variant”.
WHO classifies a variant as a VOC when it is associated with an increase in transmissibility or detrimental change in Covid-19 epidemiology; increase in virulence; or decrease in the effectiveness of public health measures or available diagnostics, vaccines, therapeutics.
