Just because a parasite is not a bear, tiger or some other large predator, that doesn't mean it can't be as deadly...if not more so. Monsters Inside Me retells the real-life, harrowing dramas of people infected by deadly parasites as doctors and scientists try to unravel each case before it's too late. Monsters Inside Me reveals what happens to unsuspecting victims when the smallest creatures turn out to be the biggest monsters. Parasites are organisms that live on or in another species, which then serve as hosts from which the parasite gains nutrients. Failing to recognize or incorrectly diagnosing a parasite can wreak havoc and sometimes cause death. "In North America, parasitic infections are somewhat rare; regardless, they can happen to anyone," says biologist/zoologist Dan Riskin, host of Monsters Inside Me. "Parasites are in the food we eat, in the water we swim and on the ground we walk," continues Riskin. "They are lurking in the shadows, waiting for just the right moment to take a host."
