    BACKGROUND: Infectious diseases continue to burden populations in Malaysia, especially among rural communities where resources are limited and access to health care is difficult. Current epidemiological trends of several neglected tropical diseases in these populations are at present absent due to the lack of habitual and efficient surveillance. To date, various studies have explored the utility of serological multiplex beads to monitor numerous diseases simultaneously. We therefore applied this platform to assess population level exposure to six infectious diseases in Sabah, Malaysia. Furthermore, we concurrently investigated demographic and spatial risk factors that may be associated with exposure for each disease.

    METHODS: This study was conducted in four districts of Northern Sabah in Malaysian Borneo, using an environmentally stratified, population-based cross-sectional serological survey targeted to determine risk factors for malaria. Samples were collected between September to December 2015, from 919 villages totaling 10,100 persons. IgG responses to twelve antigens of six diseases (lymphatic filariasis- Bm33, Bm14, BmR1, Wb123; strongyloides- NIE; toxoplasmosis-SAG2A; yaws- Rp17 and TmpA; trachoma- Pgp3, Ct694; and giardiasis- VSP3, VSP5) were measured using serological multiplex bead assays. Eight demographic risk factors and twelve environmental covariates were included in this study to better understand transmission in this community.

    RESULTS: Seroprevalence of LF antigens included Bm33 (10.9%), Bm14+ BmR1 (3.5%), and Wb123 (1.7%). Seroprevalence of Strongyloides antigen NIE was 16.8%, for Toxoplasma antigen SAG2A was 29.9%, and Giardia antigens GVSP3 + GVSP5 was 23.2%. Seroprevalence estimates for yaws Rp17 was 4.91%, for TmpA was 4.81%, and for combined seropositivity to both antigens was 1.2%. Seroprevalence estimates for trachoma Pgp3 + Ct694 were 4.5%. Age was a significant risk factors consistent among all antigens assessed, while other risk factors varied among the different antigens. Spatial heterogeneity of seroprevalence was observed more prominently in lymphatic filariasis and toxoplasmosis.

    CONCLUSIONS: Multiplex bead assays can be used to assess serological responses to numerous pathogens simultaneously to support infectious disease surveillance in rural communities, especially where prevalences estimates are lacking for neglected tropical diseases. Demographic and spatial data collected alongside serosurveys can prove useful in identifying risk factors associated with exposure and geographic distribution of transmission.

    In the University Hospital, Kuala Lumpur, from 1984 to 1990, 184 patients with acute conjunctivitis were examined for chlamydial infection by direct immunofluorescence. Overall, 52 (28.3%) were found to be positive for chlamydial antigen. There was no significant difference in the detection rate between men and women and among the 3 major ethnic groups. The detection rate was highest among sexually active adults. Epidemiological and clinical features suggest that most of the chlamydial ocular infections seen were inclusion conjunctivitis and not classical trachoma.

    According to the World Health Organization (WHO), rabies is one of the 18 neglected tropical diseases, together with dengue, leprosy, and trachoma, among others. Despite being a vaccine-preventable disease, the latest estimate of annual human rabies mortality from a 2015 study is as high as 59,000 throughout 150 countries. In human rabies, more than 95% of the cases are due to dog bites, making the elimination of canine rabies a global priority by fighting the disease at its animal source. World Health Organization (WHO), World Organization for Animal Health (OIE), Food and Agriculture Organization (FAO) of the United Nations, and the Global Alliance for Rabies Control (GARC) have warranted the One Health framework with the objective of complete eradication of dog-related human rabies by the year 2030. In an effort to rationalise the One Health approach, this scoping review found 17 studies on assessing the effectiveness of control interventions of human and canine rabies. Different strategies were implemented based on the endemicity of rabies in a particular country. Overall, the combined strategies using the One Health approach, which allows effectiveparticipation and communication between different agencies, have shown promising results in reducing rabies cases. These strategies will hopefully realise the goal in the Global Strategic Plan to achieve zero canine-mediated human rabies death by the year2030.
