TB vs malaria vs plague
It becomes a contest of numbers. There is evidence of TB infection 9000 years ago. It has the advantage of being able to infect goats and cows, and then pass along to humans. It is thought to have gotten to South America on seals and otters. This runs the count up pretty high. Malaria is in the 10s of billions, but the strains in Asia, Africa and S. America differ and are not all of them deadly.
Plague didn’t have enough millions alive to run up much of a score.
