NewsStudy highlights factors associated with higher tuberculosis risk in South Africa
Tuberculosis is the world’s top infectious killer. About 10 million people fall ill with the disease every year, and roughly 1.5 million people die because of it, according to the World Health Organization. Additionally, about one-quarter of the world’s population is infected with the disease’s causative agent Myctuberobacterium tuberculosis. ...
