I'm not doubting Brickburn but this was not the case last month when I flew to RSA with a stopover in Dakar. Like so many other things in Africa, it may just depend on who's on duty and their mood at the time.
As a side note. I did have my YF card with proof of Yellow Fever vaccination along, just in case.

As always, depends on who decides to enforce the rules on the day of arrival. After I spend all the money to arrive and go hunting I was not going home or being quarantined.
Here are three sources of information on the subject that repeat the same result.
If you transit through Senegal you need a YFC.
I was not going to argue the fine point that I did not technically transit Senegal but I did cross it's border.
Your choice!
