The immunologist said: “Much of this variation could be due to genetic variation among subjects but could also be due to viral variance.”
He added: “At the moment lots of signs and symptoms have been reported, none majorly consistently and no increase in immune or vaccine evasion, infectivity or virulence (disease severity caused by the virus) have been reported, although it is early.
“This underlines the need for testing surveillance and sequencing to be available. There have been some notable other symptoms, however, such as runny nose, scratchy throat and vertigo which have not typically been associated with Covid strains until now.”
The immunologist said: “Depending on its make-up, it is possible that a new strain could come about that surpasses the effects of prior covid variants. It is difficult to predict, based on the current track record of COVID-19 variants.
