“…The findings of the present study showed a high prevalence of IPIs with 57.5% of participants was infected with at least one species. These findings in a state in Borneo Malaysia were relatively consistent to the report from previous study among indigenous groups in Peninsular Malaysia with prevalence rates of 50% and above [2,4,7,19–21]. Similarly, the results were also consistent with previous local study conducted among other indigenous community in Saratok Division which reported high prevalence of IPIs (67.6%) [28].…”

“…Although Malaysia has undergone rapid growth in socioeconomic and development infrastructure, IPIs and malnutrition are still endemic particularly among the underprivileged indigenous communities which are closely associated with their poor socioeconomic status (SES), personal and environmental hygiene [2,4,7,17–21]. Malaysia consists of Peninsular Malaysia and Borneo Malaysia.…”

“…Malaysia consists of Peninsular Malaysia and Borneo Malaysia. Most recent studies conducted among the indigenous communities in Peninsular Malaysia between 2013 and 2015 have reported overall prevalence of more than 50% [2,7,17,21]. To date, there are relatively limited data on the prevalence of IPIs among the indigenous groups in East Malaysia or Borneo Malaysia [22,23].…”

Intestinal parasitic infections (IPIs) have been recognized as one of the most significant causes of illness among disadvantaged communities. Many studies have been conducted on the prevalence of IPIs in Malaysia. However, these studies mostly focused on the indigenous groups in Peninsular Malaysia. The present study was conducted to provide the current baseline data on prevalence of IPIs, anaemia, malnutrition and associated risk factors among the indigenous communities in Sarawak, situation at northwest Borneo island of Malaysia. A cross sectional study was conducted among the longhouses communities. Stool samples were obtained and examined for the presence of IPIs using microscopy technique. Haemoglobin measurement was done using a portable haemoglobin analyzer. Malnutrition (i.e., stunting, underweight and wasting) was assessed using the WHO Anthro software. Statistical analysis was carried out using SPSS software. A total of 341participants took part in this study. The overall prevalence of IPIs was 57.5%. Multivariate analysis indicated that the absence of toilets (OR = 1.6; 95% CI = 1.1–2.7; p = 0.002) and close contact with animals (OR = 1.8; 95% CI = 1.3–2.9; p = 0.027) as significant predictors for IPIs. The incidence of anaemia was 36.4%. The incidence of underweight, wasting and stunting were 22.2%, 5.6% and 35.4%, respectively. Multivariate analysis demonstrated that low level of parental education attainment (OR = 1.9; 95% CI = 1.2–3.0; p = 0.006) was identified as significant predictor for anaemia. The incidence of wasting was significantly associated with mild anaemia (OR = 1.2; 95% CI = 0.9–1.7; p = 0.024). Low household income was identified as significant predictor for stunting (OR = 2.1; 95% CI = 9.8–22.2; p = 0.001) and underweight (OR = 1.9; 95% CI = 5.6–18.7; p = 0.037), respectively. Essentially, the present study highlighted that intestinal parasitic infections, anaemia and malnutrition are still prevalent among rural indigenous community in Sarawak. Improvement of socioeconomic status, periodic mass deworming, iron supplementation and health education program should be included in the control and prevention of public health strategies.

“…The fact that the span of previous study and the current study is over 20 years, and both studies have the limitation of small sample size, we are unable to conclude whether there is a true reduction in seroprevalence among the aborigines and whether modernization of lifestyles contributes to the reduction. Eating with hands without proper hand washing, walking barefoot and poor surrounding sanitation evident among the aborigines reported by other researchers study (Ngui et al, ) was also observed in this study. Future larger scale studies are needed to confirm this and to also investigate the possible reasons.…”

Malaysia is a non‐endemic country for hepatitis E virus (HEV) infection. However, seroprevalence as high as 50% among samples of aboriginal people were reported over two decades ago. A total of 207 samples collected from seven aboriginal villages in rural settlements across two states in Malaysia were analysed for anti‐HEV IgG and IgM by an enzyme‐linked immunoassay. Following the detection of anti‐HEV seroprevalence, we organized health outreach to inform and educate the community. Qualitative interviews were conducted with individuals tested positive for anti‐HEV antibodies. Data derived from interviews and observations were used to investigate possible lifestyle behaviours associated with HEV infection. Anti‐HEV IgG was detected in six samples (5.9%) from the village of Dusun Kubur. Qualitative inquiry and observation study revealed poor dietary and household hygiene, contaminated food and water, contact with animal faeces, unsanitary and domestic waste disposal, and wildlife reservoirs could be the contributing factors for transmission and acquisition of HEV infection. Investigation during health outreach is important to provide insights for future empirical research and implementation for improvement of lifestyle behaviours among the aborigines. Managing the risk of HEV infection in the aborigines may reduce the risk of HEV transmission to the local communities.

“…In this study different factors had association with the increase prevalence of hookworm after multivariate analysis. This study revealed that absence of shoe wearing habit was significantly associated with hookworm infection (AOR = 3.9; 95% CI = ( 1.11-14.24) This study finding was supported by a study conducted in Wolaita Zone Southern Ethiopia [10], and Orang Asli in Peninsular Malaysia [22]. This factor is an important evidence for the high prevalence of hookworm because the transmission of the parasite is through penetration of skin by the infective filariform larvae and prevented by reduction of skin contact with potentially infected soil by wearing shoes [1].…”

Background Hookworm is a major public health problem in Ethiopia. The prevalence of Hookworm and associated factors among podoconiosis patients and healthy residents has not been studied.Objective to determine the prevalence of Hookworm and associated risk factors among podoconiosis patients and healthy residents.Methods A cross-sectional study was conducted at Debre Elias from January to February 2018. One hundred ninety two participants were included. Stool sample was collected for microscopy, kato-katz and formalin ether concentration technique. Logistic regressions were performed to assess association between variables. P-value < 0.05 was used as statistically significant.Result The prevalence of Hookworm among podoconiosis patients was 84.4% and 75% among control. Hookworm infection was relatively higher among podoconiosis patients 52.9%. Higher age group, illiterate and farmers more affected with high proportion of podoconiosis patients. Being a formers, no history of stool examination and no shoe wearing habit were significantly associated with hookworm infection (AOR = 4.1; 95% CI= (1.65- 10.11)), (AOR = 3.03; 95% CI= (1.11-8.25)) and (AOR= 3.9; 95% CI= (1.11-14.24) respectively.
