5th strain of malaria (P. knowlesi) in Malaysia

In Sabah, Sarawak and Kelantan, in the 1st quarter of this year, more than two-thirds of the 527 reported cases of malaria were due to a strain of malaria called P. knowlesi that usually infects monkeys. It is generally accepted that this strain circulates in monkeys in forested areas and perhaps rarely from an infected human to another human by mosquito carriers.

This strain of malaria is mostly found in South East Asian countries particularly in Borneo, Cambodia, Malaysia, Myanmar, Philippines, Singapore, and Thailand.
