Malaria in Malaysia

11 November 2014

A recent study of patients hospitalised with malaria in Malaysia during 2013, showed that 68% were suffering from Plasmodium knowlesi infection. P. knowlesi is increasingly associated with malaria deaths and is three times more likely to cause severe malaria than P. falciparum in Malaysia.

The main host of P. knowlesi parasites is the long-tailed and pig-tailed macaque monkey, found in the tropical forests of Malaysia and other areas of Southeast Asia. P. knowlesi infections are concentrated in areas of Malaysia where deforestation has taken place and palm oil production has substantially increased human interactions with macaques.

Advice for Travellers

There is a high risk of malaria risk in limited foci in deep hinterland areas of Sabah and Sarawak and a central area in Peninsular Malaysia all year round. Antimalarial prophylaxis is recommended for high risk areas. Further details on the Malaysia country record.
