    Diseases can sometimes jump from animals to humans: a phenomenon known as zoonosis.

    Think about the last time you got sick: How did it happen? Did you kiss someone with a cold? Did a kid sneeze on you? Or maybe you didn’t catch it from a fellow human at all: maybe you got a zoonosis from a non-human animal!

    Zoonosis occurs when pathogens, or tiny, disease-causing entities such as viruses or bacteria, switch their targets. Here’s how it works:

    Generally, pathogens tend to infect particular species, similar to how predators, such as lions, prefer to hunt a particular type of prey.

    However, sometimes a predator will deviate from its preferred meal. For example, although we often don’t appear on a lion’s menu, they certainly wouldn’t scoff at the opportunity to dine on tasty human flesh should such an opportunity arise. Pathogens act in a similar way, changing targets with changes in their environment.

    The outbreak of mad cow disease is one such example of how a pathogen usually associated with cows successfully infected humans. The toxocariasis infection, too, can be passed from dogs to humans via the pathogen called roundworm.

    Zoonotic pathogens are also especially dangerous, as they can “hide” in animals without causing them harm, thus making it impossible at times to know when and where they appear or reappear in human populations.

    The ebola virus, among the most deadly viruses known to us, often appears and disappears suddenly, emerging from the animal kingdom only to quickly disappear again. Consider the latest outbreak in West Africa in 2014, which occurred after many years without any ebola incidents.

    Also distressing is the fact that zoonotic pathogens are quite common. In fact, a study published in the prestigious journal Nature found that, from the years 1940 to 2004, approximately 60 percent of new emerging infectious diseases were zoonotic.

    But how exactly do these pathogens work? The next few blinks will show you just that.
