Severity or disease duration

According to severity of the disease
Mild	Early diagnosis and treatment Responds to medical treatment Typical clinical presentation Good prognosis
Moderate	May present late with typical or atypical symptoms May present with complications Variable response to treatment
Severe	Presents with complications or prolonged illness Immunocompromised Common in extremes of age Delayed diagnosis and treatment Surgical treatment may be required in addition to medical treatment Increased morbidity and mortality
According to the duration of disease
Acute	Lasts few weeks Patient acutely ill Mostly in HIV-associated patients Impaired consciousness Seeks medical treatment early due to sudden deterioration
Subacute	Lasts less than 4 weeks Patient acutely ill Mostly in HIV-associated patients Impaired consciousness Seeks medical treatment early due to sudden deterioration
Chronic	Lasts more than 4 weeks Gradual deterioration of patient Prolonged history of atypical symptoms Common in older patients
Recurrent	Multiple episodes which lasts less than 4 weeks History of incompliance to medication immunosuppression may be the underlying cause
