What is the most common method of transmission of a zoonotic disease?
Most exposure occurs when droplets are created from birthing tissues (placenta, birthing fluids), soil contaminated with feces, urine or bacteria and a person breathes in the dust particles. Occurs by ingesting food or water contaminated with a pathogen.
How do viruses transfer from animals to humans?
First, the original host—the species that serves as the virus’s so-called reservoir—needs to rub elbows with people at a time when it is shedding enough virus for people to get exposed to a significant amount. Next, the virus has to be equipped with the molecular machinery to enter human cells.

What is zoonotic parasite?
A zoonotic parasite is a parasite that can be transmitted between animals and people. Humans are not the primary host, so the zoonotic parasite will act differently in humans. Zoonotic parasites cause health problems in humans that range from those that are minor to the very serious.
