Dengue remains a public health threat that consumes a significant number of resources for its prevention and control. This systematic review aimed to solidify recent costing evidence in dengue management among South East Asian (SEA) countries. All studies conducted between 2010 and 2020 were retrieved using four international databases i.e. PubMed, Scopus, Web of Science, and Emerald Insight. The review was reported according to PRISMA guidelines. Quality assessments were done independently by two reviewers using a checklist adapted for the cost of illness studies. We identified 13 original articles representing several SEA countries. Among the common reported costing measure include total cost/ health expenditure; direct medical cost; direct non-medical cost; and indirect cost. The estimated total cost for dengue management varied between countries largely due to the difference in the total incidence of dengue cases. The estimated cost spent on dengue per capita GDP ranges from less than 0.001% to 0.1%, depending on the recorded number of dengue cases of the year. The majority of the articles focused on the economic burden from the perspective of treatment such as hospitalization and ambulatory care. In a nutshell, the economic burden of managing dengue infection is costly and the evidence suggests a steady increase in health expenditure with the growing number of dengue cases

Environmental Determinants in Sustaining the Transmission of Lymphatic Filariasis: A Systematic Review IntroductionSince mass drug administration continues in many of the endemic countries, it is vital to synthesise evidence to adapt the challenges contributed by the environments. As such, the aim of this review was to explore relationship between lymphatic filariasis prevalence and potential environmental determinants .MethodsWe searched the electronic databases PubMed, Web of Science, Cochrane, and Scopus between Jan 1, 2013, and Dec 31, 2022, for studies fulfilling the following criteria: it was an original article investigating the environmental determinants associated with transmission of lymphatic filariasis; and the study was published in English. The quality assessment tools for observational studies from the National Heart, Lung, and Blood Institute was used to assess the study quality. This systematic review was registered with the PROSPERO database (CRD42023393018).ResultsWe identified 409 potentially eligible published articles, of which 11 met our inclusion criteria. The main environmental determinants associated with lymphatic filariasis transmission were Normalised Difference Vegetation Index (NDVI), land cover, distance to waterbody, rainfall/precipitation, elevation, slope, day land surface temperature, average annual temperature, house type and distance to stable light. ConclusionsThis review is one of the steps towards understanding the associations between environmental determinantsand transmission of lymphatic filariasis. These results can be used in future evidence-based strategies to strengthen surveillance and control strategies.

Cabaran Dalam Pencegahan dan Kawalan Plasmodium Knowlesi Malaria Di Rantau Asia Tenggara – Ulasan Naratif PengenalanDi sebalik kejayaan program penghapusan malaria manusia, terdapat peningkatan yang membimbangkan berkenaan jangkitan malaria Plasmodium knowlesi (P. knowlesi) di rantau Asia Tenggara. Pemahaman menyeluruh tentang cabaran dalam mencegah dan mengawal malaria zoonosis ini mesti diutarakan, terutamanya apabila menentukan strategi paling berkesan untuk menyekat penularan penyakit.MetodologiDi sebalik kejayaan program penghapusan malaria manusia, terdapat peningkatan yang membimbangkan berkenaan jangkitan malaria Plasmodium knowlesi (P. knowlesi) di rantau Asia Tenggara. Pemahaman menyeluruh tentang cabaran dalam mencegah dan mengawal malaria zoonosis ini mesti diutarakan, terutamanya apabila menentukan strategi paling berkesan untuk menyekat penularan penyakit.Hasil KajianKepelbagaian manusia, seperti sosioekonomi dan sosiobudaya tempatan yang majmuk, persepsi yang rendah dan pematuhan optimum terhadap langkah-langkah pencegahan dan kawalan perlu ditangani. Isu dana nasional, pelaksanaan program, dan birokrasi mesti diselesaikan dalam memastikan keberkesanan peranan kerajaan dan kerjasama pelbagai sektor apabila melibatkan pengurusan penyakit malaria. Kejayaan sesuatu program akan terhalang sekiranya tiada sokongan daripada pemimpin masyarakat dan bertentangan dengan dinamik sosial. Kebolehsuaian nyamuk Anopheles bertanggungjawab terutamanya terhadap cabaran yang dihadapi dalam kawalan vektor. Kesan anjakan ekologi dan perubahan iklim, ditambah dengan aktiviti antropogenik mewujudkan limpahan zoonosis dan variasi penyesuaian yang mengubah landskap transmisi sylvian dan manusia.KesimpulanCabaran daripada pelbagai faktor mengurangkan keberkesanan dalam mencegah penularan penyakit ini. Pendekatan baharu mesti dibangunkan untuk mencapai kawasan terjejas dengan intervensi jangka panjang, komprehensif dan berkesan.
