Also, what are the numbers rather than the percentage? 59 this week and 41 the week before. Sounds a lot less doomy than 43%. But 43% makes the headlines.
The percentage matters a great deal, and for understanding this variant versus another variant more than pure numbers. If we had 100 yesterday and 101 today, that would suggest we are on a very flat trajectory - far less to worry about than a 43% increase.
Maybe it is you who doesn't understand the maths involved with mapping the trends? We need to know the doubling time.
