Abstract
INTRODUCTION: Zoonotic malaria infection among human has contributed to public health burden in Malaysia. In Batang Padang district, Plasmodium knowlesi malaria cases was 600% increase in 2018, while observing reduction in human malaria since 2012. This case report aims to describe an epidemiological investigation and integrated management of knowlesi malaria clusters at Batang Padang district in 2018, following identification of patients whom did not have clear risks for knowlesi malaria. METHODS: Registered malaria cases in 2018 at Batang Padang were investigated and managed using integrated vector management approach for risk factors of P.knowlesi infection. Identified cases, hosts and vectors data was plotted into risk map using geographical information system. Multi-agencies actions were implemented to halt ongoing malaria infection. RESULTS: A total of 27 patients infected with P.knowlesi were included with median age of 40.0 (IQR:17.0), consisted of 17(63.0%) males and 10(37.0%) females, and predominantly Orang Asli (81.5%). Most of them were geographically clustered into two localities. 18(66.7%) patients had history of jungle tracking within incubation period of knowlesi malaria, but 2(7.4%) children below 12 years old and 6(22.2%) women did not go into jungles. Nearly half (45.5%) of 11 macaques were identified to host P.knowlesi, while breeding of Anopheles leucosphyrus larvae were detected within the localities. All macaques were destroyed, and vector control was undertaken to observe reduction of knowlesi malaria cases. DISCUSSION: This study suggested petting a macaque as a risk behaviour among Orang Asli in Batang Padang and may add information in knowlesi malaria prevention, especially among this population.
