It is caused by Plasmodium species, most commonly, P. vivax, P. ovale, P. malariae and P. falciparum, and rarely P. knowlesi. Malaria remains a significant global health issue and is a medical emergency. It is also an important cause of morbidity and mortality in endemic areas, particularly in at-risk groups. In Hong Kong, where malaria is non-endemic, more than 20 cases of malaria per year have been notified in recent years. We still have chances encountering patients with malaria presented to public or private emergency departments. High index of clinical suspicious is utmost important for not missing a case of malaria. A practical approach for prompt identification of patients with severe malaria is essential, followed by appropriate initiation of appropriate effective antimalarial treatment within 24 to 48 hours of symptoms onset after blood taken for thick and thin smears for diagnosis.
