Mysterious new disease has left scores of people in Asia and some in the U.S. 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 is unknown but the disease does not seem to be contagious.
It appears to be another kind of acquired immune deficiency that is not inherited and occurs in adults.
However it doesn’t spread the way AIDs does through a virus, said Dr Sarah Browne, a scientist at the National Institute of Allergy and Infectious Diseases (NIAID), which is part of the National Institute of Health.
