a virus spreading from one host species to humans

Explanation:

Emerging virus diseases are viruses that have in recent times occured among a population or those whose prevalence or geographic area is swiftly growing or likely to rise in the near future.

For an emerging disease to spread, it requires

(1) the infectious agent has to be brought in to a susceptible population

(2) the agent shows capability to easily infest form an individual to another leading to disease in the process

(3) ability to keep up affecting more individuals within the population.

A lot of emerging diseases occurs when infectious organism in animals are transferred to humans (it's called zoonoses). As human population rises and they occupy more geographical regions, the probability that humans have more contacts with animals that host the causative organism rises too

Causing a major threat to human health.

Therefore, we can rightly say an Emerging viruses that infect human cells can originate from a virus spreading from one host species to humans.
