Thrombocytopenia is not associated with disease severity, although, somewhat paradoxically, platelets have been shown to contribute to disease pathology in animal and in human malaria 39 moreover, in human infections, platelets may form ‘clumps’ with infected erythrocytes 40 therefore, one explanation of this paradox could be that low.
