FIG. 4.21 Dependence of the viscosity of infected blood in malaria on different parasitemia levels (i.e., the fraction of infected RBCs with respect to the total number of cells in a unit volume). Infected blood is modeled as a suspension of healthy and infected RBCs having a spherical geometry ( Fedosov et al., 2011b ). The diamond symbol corresponds to a simulation with adhesive interactions among RBCs. Experimental data are from Raventos-Suarez et al. (1985) . γ ˙ = 230 s − 1 in all cases.

FIG. 4.22 Relative apparent viscosity of blood in malaria for various parasitemia levels and tube diameters. Symbol “x” represents the schizont stage with a near-spherical shape of infected RBCs. The inset illustrates the model, where healthy (red) and infected (blue) RBCs in Poiseuille flow in a tube of diameter D = 20 μm are simulated. In all cases, the hematocrit is 45%. Experimental data are from the empirical fit by Pries et al. (1992) . Reproduced with permission from Fedosov et al., Proc. Natl. Acad. Sci. U.S.A. 108 , 11772–11777 (2011).
