LONDON : Chris Whitty, the chief medical officer for England, recently announced that the delta variant is no longer of concern because it now comprises 98 per cent of new cases in the country and is therefore “the normal variant".
This virus has spread to at least 90 countries and is 50 per cent more transmissible than the alpha variant (the variant first identified in Kent), which is around 50 per cent more transmissible than the original coronavirus that caused the pandemic.
With cases rising exponentially and restrictions lifted, it is important to understand how well the vaccines are faring against the delta variant.
