The freshwater snails are hosts, much like mosquitos in this diagram. They host platyhelminthes. The ascaris and tapeworms are also helminths. As far as I know anyway. I can understand that they wanted to show animals in the diagram because you can actually avoid those but avoiding the snails won't actually help because the worms infect by being excreted by the snail and infecting another host(human or other), usually in water.

And they couldn’t be bothered to get a picture of an assassin bug.

This is a combination of vectors and physical attack. Humans committing homicide vs a mosquito carrying a disease.

There is a note saying that, it's on the bottom left.

That said, it could and should have been more visible.

It says that in the small print. But mosquito sounds better than some difficult to pronounce Latin name.

They are mainly in South America and some in Central America, I think. They carry a parasite that causes Chagas disease.

So, most assassin bugs are actually be beneficial insects. It's a large group of true bugs, and most of them feed on other invertebrates.

As a@athairmor pointed out there are some types that feed on human blood and spread potentially deadly diseases. But these are the exceptions.

You should be concerned if you live in areas where the parasite carrying types live.

And you should be concerned if you are harassing/handling other types of assassin bug because many of them have very painful "stings" (it's not actually a sting it's their version of a bite, since they have needle like mouths they can use to jab in defense). So long as you leave those types alone, you generally won't end up on their list.

I always thought rabies was exceptionally rare, like just a handful of cases per year? Or is that just the US

Exactly. Bears are perfectly safe

Also, notice how other humans are high up on the chart

They haven't been that big of a deal ever since we invented the holy hand grenade.

Though holy hand grenades would be high on the list if they were an animal. But such is the price we pay to be safe from the mighty rabbit.

You should watch Night of the lepus

Did you get it from the same guy who sold me the rock that keeps tigers away?

He's a good guy,

...At least there's no snakes, right..?

I'm sure it wasn't scaled or normalized at all. It's global annual deaths.

It would be interesting to see what percentage of annual premature deaths they account for in countries with any deaths.

Ie lions and hippos are presumably a much large percentage of annual premature deaths in countries where there are any lion and hippo deaths, whereas mosquito deaths happen in many more countries, and homicides in basically all countries.

I'm actually quite shocked by the number of lion and hippo deaths.
