Topic overview

Start with the big picture

The lesson surveys the five Plasmodium species that infect humans, highlighting the substantial morbidity and mortality associated with P. falciparum and the relapse potential of P. vivax and P. ovale. It follows infection from mosquito transmission through liver and red-cell stages, then connects these processes with clinical manifestations. Diagnosis centers on thick and thin blood smears, with rapid antigen tests as an alternative when microscopy is unavailable. Treatment topics distinguish uncomplicated from severe malaria and address species, resistance, pregnancy, and G6PD status. The broader discussion also covers chemoprophylaxis, adverse effects and interactions, monitoring in severe cases, non-pharmacologic prevention, vaccination, and public health reporting.
