Disease

Researchers have identified a mysterious new disease that has left scores of people in Asia and some in the United States with AIDS-like symptoms even though they are not infected with HIV.

The patients’ immune systems become damaged, leaving them unable to fend off germs as healthy people do.

What triggers this isn’t known, but the disease does not seem to be contagious.

This is another kind of acquired immune deficiency that is not inherited and researchers are calling this new disease an “adult-onset” immunodeficiency syndrome because it develops later in life and they don’t know why or how.
