We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox,a disease
usually found in the African rain forest, suddenly turns up in children in the American Midwest, it's hard
not to wonder if the disease that comes from foreign animals is homing in on human beings. "Most of the
infections(感染) we think of as human infections started in other animals, "says Stephen Morse, director
of the Center for Public Health Preparedness at Columbia University.
It's not just that we're going to where the animals are; we're also bringing them closer to us. Popular
foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen's pets, and
she now thinks that keeping foreign pets is a bad idea. "I don't think it's fair to have them as pets when we have such a limited knowledge of them, "says Isaksen.
"Laws allowing these animals to be brought in from deep forest areas without stricter control need
changing," says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected
animals may infect their owners. We know very little about these new diseases. A new bug(病毒) may
be kind at first. But it may develop into something harmful(有害的).
Monkey-pox doesn't look a major infectious disease. But it is not impossible to pass the disease from
person to person.
