In infected monkeys, it is fatal in most cases within two weeks of infection.

Like HIV, another well-known virus that was also born in African monkeys, the arterivirus hijacks the immune system, deactivates the main defense mechanisms and breaks down the body, cell by cell, settling in the long-term organization.

This virus has figured out how to gain access to human cells, multiply and evade some important immune mechanisms that we expect to protect ourselves from an animal virus, that’s pretty rare.”, said professor of molecular, cellular and developmental biology Sara Sawyer, lead author of the study. “We have to pay attention to it.”
