Freshwater Snails
The freshwater snail might look cute and tiny but they’re responsible for infecting people with schistosomiasis, a parasitic illness responsible for killing 4,400 people annually. This snail is found in regions of South American, Asia and Africa. What’s more alarming is the fact that a person doesn’t even have to touch the snail to get infected. If their skin touches the same water the snail is in, they will become infected. Once the parasitic illness is in the body, it will attack the spleen, intestines and liver.
