Wanna know how the numbers change for "Other Humans" when deaths due to car collisions are included? It gets 1.35 million added to it, and those were 2016 numbers.
Automobile drivers are by far the most deadly animal, blowing mosquitoes completely out of the water!
To the 400k you should add 1.2-1.4 million traffic deaths, 700k suicides, and we are not even talking about the deaths from armed conflicts, that climbed over 200k due to the war in Ukraine.
Additionally, this is counting the diseases mosquitos spread so what about the diseases humans spread regularly? Not counting pandemics or if they count, average them out across the same time span these averages are taken from.
Dog and mosquitoes get to have spreading disease added but human didn't get to have manslaughter and war added. So basically mosquitoes kill are 100% unintentional, very much like the pedestrian getting killed by automobile, but mosquitoes get blamed for it but human doesn't.
Fun thing about Chagas, the disease Assassin bugs transmit to gain their bodycount. Trypanosoma cruzi (the protozoa that cause the disease) has developed a nasty little trick where it'll offload snippets of its DNA into the host organism. This will usually cause a auto-immune disease, both weakening the host and diverting some of the efforts of the immune system.
The interesting thing about this is one of the cells it can offload the DNA into are sex cells which means it becomes a heritable trait and becomes a part of the host genome. So there are naturally GMO humans out there with chunks of protozoa DNA in them... usually to their sorrow since the DNA is geared for causing auto-immune disorders.
