The positive diagnosis was based on clinical elements (the altered general condition, conscious, with left facial paralysis, pallor, lingual candidiasis, etc.), the biological samples (blood cell identification, erythrocyte sedimentation rate (ESR), glucose, C-reactive protein (CRP), blood cultures, CD4 count, viral load (VL), Toxoplasma IgG and IgM antibodies, etc.)and paraclinical investigations (chest radiography, brain computed tomography (CT) scan, abdominal ultrasound). The gene discussed is CRP; the disease is facial paralysis.
