People see that number and think is only 2x or 3x, but it's part of a growth calculation so 7 is hundreds or thousands of times more infectious than 2.5.
The approximate formula is R[sub]0[/sub][sup]n[/sup], where n is the number of infection cycles.
Our video doctor friend did a nice summary, for some reason this video sometimes loads part way through the video and you have to go back to the start to get at the basics;
