“Unless we say the variant makes you cough in a different way or cough more heavily, I don’t see how you can gain that extra distance, like in the long jump so to speak.”

“I fully understand why Sadiq is saying what he is saying because the increase in cases there in recent weeks is huge and the pressure on hospitals is even greater than here.”
