This message becomes more relevant now than before with the growing presence of the COVID 19 variants. The new variants are more transmissible; for example, the UK variant is said to be 56 percent more transmissible than the original COVID 19 virus.
What does that mean?
It means if the original one takes 20 days to double the number of us infected, this variant will do it within 10 days. Some epidemiologists predict the numbers can go up by more than 10 fold if the current lockdown restrictions are removed.
