  • any "sign of severe/complicated malaria" from the list below.

 

In young children, a clinical diagnosis of severe/complicated malaria can also be made if there is;

  • fever (history of fever or axillary temperature ³ 38.5°C) PLUS
  • any "general danger sign in young children" from the list "Signs of Severe/complicated malaria”.

  • Repeated profuse vomiting.
  • Circulatory collapse or shock (cold limbs, weak rapid pulse) (systolic BP of less than 80mmHg in adults and less than 50mmHg in children.

 

Laboratory Findings:

  • Severe normocytic anaemia (severe anaemia; haematocrit <15% or Hb <5g/dl).
  • Signs of hypoglycemia (sweating, pupillary dilation, abnormal breathing, coldness, blood sugar- <40mg/dl. or 2.2mmol/L).
  • Renal Impairement -Signs of renal failure (passing very little urine)-Serum creatinine >265umol/l.
  • Signs of haemoglobinuria (dark or cola-colored urine).
  • Hyperparasitaemia (250,000 parasites/microlitre).
