Diagnosis:
antigen detection in blood, urine or broncho-alveolar fluid, OR positive microscopy, OR mycological culture of blood, urine, broncho-alveolar fluid, CSF or tissue biopsy or PCR in blood OR other clinical samples. Next generation sequencing may provide rapid diagnosis

Notes on treatment:
see Anti-infective drugs & ARVs table for treatment optimization
