Ray fungus, a bacterium which is a member of the order Actinomycetales. (05 Mar 2000) |

| middle stage HIV disease | <disease> This refers to an HIV infection that is characterised by signs and symptoms of HIV that are not life-threatening. Examples include oral thrush, gingivitis, seborrheic dermatitis, molluscum contangiosum, fevers, fatigue, lymph node swelling, malaise and weight loss. This stage can be a signal for the conversion from asymptomatic HIV disease to HIV disease (moe pronouced symptoms include joint pains). AIDS is diagnosed after HIV disease has started to manifest life-threatening oppotunistic infections (for example pneumocystis, cryptosporidium, toxoplasmosis, etc). (27 Sep 1997) |
