At what stage would these infections occur? Would you normally see this six months after a possible exposure? Also, is an endoscopy always reliable in diagnosing esohogial candida?
Oral thrush can appear when T cells drop to about 350 cells or less. Usually oral disease precedes esophageal disease, which is considered an AIDS-defining illness and usually happens when T cells are about 200 or less. It is possible 6 months after exposure, but would be pretty unusual. Endoscopy is an excellent way to diagnose candida in the esophagus.
