Infectious diseases in South East Asia

MORU aims to fight the infectious tropical diseases affecting rural communities in Asia and elsewhere in the developing world. MORU's malaria research aims to directly improve the treatment of the disease globally. It's researchers focus on the treatment of severe malaria, the spread of antimalarial drug resistance, and the pathophysiology of falciparum and vivax malaria. These studies are used to formulate novel adjuvant therapies, and have been translated into recommendations for the use of artemisinin based combination therapies.
