Simulation of malaria-infected blood in a cylindrical vessel. Shown in red are healthy red blood cells, and in orange are Plasmodium falciparum-parasitized red blood cells. Blood hematocrit is 30% and the parasitemia level (percentage of infected RBCs with respect to the total number of cells in a unit volume) is 20%. The small particles in the background are markers of the plasma flow. (See Fedosov et al., 10.1371/journal.pcbi.1002270)
