Plasmodium knowlesi infecting humans in Southeast Asia: What’s next?

Nantha Kumar Jeyaprakasam; Jonathan Wee Kent Liew; Van Lun Low dkk.

PLOS Neglected Tropical Diseases, Vol. 14 No. 12 · 2020 · Inggris · PLOS Scopus

Plasmodium knowlesi, a simian malaria parasite, has been in the limelight since a large focus of human P. knowlesi infection was reported from Sarawak (Malaysian Borneo) in 2004. Although this infection is transmitted across Southeast Asia, the largest number of cases has been reported from…

Gravid oviposition sticky trap and dengue non-structural 1 antigen test for early surveillance of dengue in multi-storey dwellings: study protocol of a cluster randomized controlled trial

Jonathan Wee Kent Liew; Sivaneswari Selvarajoo; Wing Tan dkk.

Infectious Diseases of Poverty, Vol. 8 No. 1 · 2019 · Inggris · DOAJ Scopus

Abstract Background Dengue is a global disease, transmitted by the Aedes vectors. In 2018, there were 80 615 dengue cases with 147 deaths in Malaysia. Currently, the nationwide surveillance programs are dependent on Aedes larval surveys and notifications of lab-confirmed human infections. The…

Effect of different habitat types on abundance and biting times of Anopheles balabacensis Baisas (Diptera: Culicidae) in Kudat district of Sabah, Malaysia

Tock H. Chua; Benny O. Manin; Indra Vythilingam dkk.

Parasites & Vectors, Vol. 12 No. 1 · 2019 · Inggris · DOAJ Scopus

Abstract Background We investigated the effect of five common habitat types on the diversity and abundance of Anopheles spp. and on the biting rate and time of Anopheles balabacensis (currently the only known vector for Plasmodium knowlesi in Sabah) at Paradason village, Kudat, Sabah. The habitats…

Prevalence of simian malaria parasites in macaques of Singapore
