Probably the rise above the baseline is not large enough in most years. But yes, Influenza and Malaria would easily top the list every year with hundreds of thousands of casualties.
Spanish Flu is on list. And it killed 50 to 100 MILLION. Way, way more than the typical yearly flu did in the two years it was active. And probably more than all the years since, combined.
It also killed many healthy people possibly due to auto immune. Verse typical influenza which only weakens body so other normally non-lethal factors are enough to kill.
probably focused on pandemic illnesses rather than seasonal illnesses. seasonal illnesses kill more people over time but pandemic illnesses are potentially more dangerous since people often don't have antibodies to fight them.
