Katlyn, I find it crazy too how a small little critter can infect people with all sorts of diseases of different kinds like viruses, bacteria, prions, parasites, and more. The concept of zoonosis is definitely bizarre especially when the potential resivoir is something tiny like a mosquito or a tsetse fly which only gets to be the size of a fingernail and has the potential to infect you with diseases capable of killing us. The role of humans in the environment has become larger in recent decades and the reading in this class has prompted me to also realize how humans being at the top of the food pyramid really places us at a higher risk of contracting diseases through what we eat.
