Geographic variations in malaria pathogenesis.
South East Asia | Africa | Ref |
---|---|---|
Low transmission in general | High transmission | [38] |
Severe malaria affects all age group | Severe malaria affects mostly the children under 5 yrs of age | [39] |
Multiorgan failure is common with seizures, respiratory distress, and anemia being more common in children whereas renal and hepatic failures are in adults. | Cerebral malaria, severe anemia, and respiratory distress are common | [39, 40] |
Total parasite burden is associated with risk of severe malaria and deaths | This relationship is less clear as children tolerate high parasitemias without developing severe malaria. | [38] |
Rosetting is not associated with severe malaria | Rosetting is associated with severe malaria | [41] |
Platelet-mediated clumping is associated with severe malaria | Platelet-mediated clumping is associated with severe malaria or high parasitemia | [41] |
