HCQ - for Malaria, and ivermectin for Chagas ???
Figure 1
(a) Malaria parasites in early form (inside green squares); (b) Chagas parasite (inside red square); (c) blood cell that looks very similar to a Chagas parasite (inside blue square).
Malaria parasites have a ring shape (Figure 1(a)) while Chagas parasites have a curved shape, similar to a shrimp (Figure 1(b)). This difference in their morphology prevents us from using exactly the same features during the very important stage of features selection.
