False, but not misleading

An infographic tweeted by Bill Gates recently on the world’s deadliest animals

He’s trying to make the point that malaria is a really big deal, killing more people than human violence, which is true, and which is the impression from the infographic, so it’s not misleading in that sense.

However, mosquitos don’t rend people limb from limb. The mosquito deaths are due to mosquitos infecting people with malaria parasites. The human deaths, however, are just directly due to violence. If  he’d included deaths due to human-human transmission of infection (influenza, tuberculosis, HIV, …), humans would easily be at the top of the list again.
