[2025-10-02T02:53:12.086555] [PI reasoning] **Clarifying stages of malaria**

I'm reflecting on the difference between pre-erythrocytic and exo-erythrocytic stages in malaria. Pre-erythrocytic involves initial hepatic schizonts, while exo-erythrocytic includes secondary hepatic schizogony, especially in species like vivax and ovale which can cause relapses due to hypnozoites. This indicates that causal prophylaxis aims to abort infection at the liver stage to prevent blood stage infections. I want to confirm the idea that pre-erythrocytic schizogony is the correct answer before I proceed.
