    Singapore Med J, 1970 Dec;11(4):283-6.
    PMID: 5511861
    300 patients (185 males, 115 females) were examined for intestinal parasites. About 40% of these patients was infected, 14% of which was heavily infected. The highest prevalence and intensity of infection with soil-transmitted helminths was found among Malays and Indians of different ages. Heavy infections with these helminths were also frequently encountered in young Chinese. Helminthic infections in patients over 60 years of age was significantly lower. There was no significant differences in the prevalence and degree of infection among males and females. The commonest helminth encountered was Trichuris trichiura, which usually occurred as trace single infections. Mixed infections with Ascaris and Trichuris, usually with the former as the predominating parasite, were also frequently observed.

    Introduction: Worm infection is one of the major global public health problems especially among rural communities.
    Objectives: to determine the prevalence of intestinal worm infection and factors associated among Semai Aboriginal
    children aged between 6 to 13 years in Tapah, Malaysia. Methods: A cross-sectional study design was used in this
    study. The estimated sample size was 508. Data was collected using a validated pretested questionnaire. Faecal
    samples were also examined. Data was analysed using SPSS version 22. Results: The response rate was 80.9%.
    The overall mean age of the 411 respondents was 10.1 years(95% CI = 9.89, 10.22). Majority (71.5%) were poor.
    Prevalence of intestinal worm infections was 60.8% and 57.2% had multiple infections. The multiple logistic
    regression analysis showed that those with poor hygiene practices were 2.18 times the odds of worm infection
    when compared with children with good hygiene practices (95% CI = 1.4, 3.4). Similarly, poor attitudes towards
    prevention of worm infection increased the odds of having worm infection by 1.62 times among Orang Asli children.
    Children living without toilets had 2.45 times higher odds as compared with those who had proper toilets. Absence
    of river near by these areas where there is no safe water supply also increases the risk of worm infection among
    children by 1.84 times among Orang Asli children. Conclusions: the prevalence of worm infection is still very
    high among rural Aboriginal community. Current control measures should be reassessed to enable introduction of
    effective measures to reduce the worm infection among Orang Asli children.

    PMID: 725660
    A survey of workers and families resident in an oil palm estate in Malaysia revealed high incidence of parasitic infections. The commonest parasites are T. trichiura (56%), A. lumbricoides (52%), hookworm (28%), Entamoeba coli (11.3%) and Giardia lamblia (11.3%). Mixed infections by two or more parasites was seen in 46% of the subjects. Anaemia was present in 70% of children with hookworm infection. Eosinophilia was observed in 69% of subjects. One each of Hymenolepis nana and Hymenolepis diminuta infection was detected. This is the first report of Hymenolepis diminuta infection in man in Malaysia.

    PMID: 7121344
    A study conducted in. all the government schools in Wilayah to find the prevalence rate of worm infection in. urban schools revealed that 50 percent of the 7,682 school children. examined suffered from helminthiasis. More than 50 percent had mixed infections, worm infection was more prevalent among Malays and Indians. Both males and females had an equal prevalence of worm infection. Schools near the squatter areas had high infection rates. This was attributed to poverty, cultural factors, and environmental sanitation in the squatter areas.

    BACKGROUND: Formerly known as the Malaysian hunter gatherers, the Negrito Orang Asli (OA) were heavily dependent on the forest for sustenance and early studies indicated high prevalence of intestinal parasitism. Initiation of a redevelopment program in the 1970s aimed to demarginalize the OA was expected to reduce soil transmitted helminth (STH) infections. Gradually, the OA were relocated to new resettlement areas at the peripheries. The aim of this study was to compare STH infections between Negritos who are still living in the inland jungle with those living in resettlements.

    METHODOLOGY/PRINCIPAL FINDINGS: A total of 416 Negrito participants were grouped into two categories of communities based on location; Inland Jungle Villages (IJV); and Resettlement Plan Scheme (RPS). Iodine wet mount, formalin-ether sedimentation, modified Trichrome and modified Ziehl-Neelsen staining and Kato-Katz methods were performed on stool samples. A questionnaire was used to collect information regarding demographic, socioeconomic, environmental and hygiene behaviors. Prevalence of STH was significantly higher in IJV (91.3%) versus RPS (83.1%) (P = 0.02). However, the percentage of individuals with severe intensity of Trichuris trichiura infections was significantly higher in the RPS (17.2%) compared to IJV (6.5%) (P = 0.01). Severe Ascaris lumbricoides infection was observed at 20.0% amongst RPS Negritos and 15.0% amongst IJV (P = 0.41). Whilst for hookworm infection, both prevalence and individuals with moderate to severe infections were higher in the IJV (26.2%, 41.0%) versus RPS (18.7%, 24.0%) (P values = 0.08, 0.09), accordingly. The prevalence other intestinal parasitic infections (e.g. Entamoeba sp., Blastocystis and flukes) was also higher in IJV versus RPS. Apart from poor hygienic behaviors as significant risk factors in both communities, low socio-economic status was highly associated with STH infections in RPS (P<0.001) but not significantly associated in IJV.

    CONCLUSIONS: The findings showed that ex situ development plan by RPS has not profoundly contributed to the STH reduction among the OA. Conversely, burden rate of T. trichiura infections increased due to their extreme poverty and poor hygienic behaviors. Here, we are suggesting biannual mass albendazole intervention (triple dose regimens in RPS, but a single dose in IJV) and community empowerment to both communities. For a long-term and better uptake, these strategies must be done together with the community input and participation, respecting their traditional customs and accompanied by recruitment of more OA people in the health-care taskforce.

    This study aims to determine the prevalence of protein-energy malnutrition and its association with soil-transmitted helminthiases in Orang Asli (Aborigine) children in Selangor, Malaysia. The results obtained from 368 children aged 2-15 years showed that the overall prevalence of mild and significant underweight was 32.1% and 56.5% respectively. The prevalence of mild stunting was 25.6% while another 61.3% had significant stunting. The overall prevalence of mild and significant wasting was 39.0% and 19.5% respectively. The overall prevalence of ascariasis, trichuriasis and hookworm infection were 61.9%, 98.2% and 37.0% respectively and of these 18.9%, 23.5% and 2.5% of the children had severe infection of the respective helminthes. The overall prevalence of giardiasis was 24.9%. The present study vividly shows that stunting and underweight are highly prevalent among Orang Asli children and therefore of concern in this community. In this population intestinal parasitic infections, especially severe trichuriasis and giardiasis, were identified as the main predictors of stunting and wasting respectively, in addition to age between 2 to 6 years.

    The productivity of smallholder sheep and goat flocks is constrained by high morbidity and mortality of young stock due to helminthosis and coccidiosis. We hypothesized that gastrointestinal parasites are prevalent and may cause severe infections amongst small ruminants in Malaysia. A cross-sectional survey was conducted between March and December 2019 to investigate the prevalence, risk factors, and levels of infection with gastrointestinal strongyle and coccidia in selected smallholder goat flocks in Negeri Sembilan, Malaysia. A total of 257 blood and fecal samples and management data were collected from four farms in Negeri Sembilan. Gastrointestinal parasites were detected by routine sodium chloride floatation, and the McMaster technique was used to quantify the fecal eggs/oocysts per gram outputs (EPG/OPG). The severity of infection was classified as mild (50-799), moderate (800-1200), or severe (>1200). The packed cell volume (PCV) was determined by microhematocrit centrifugation and classified as anemic or non-anemic. Coprological examination revealed an overall prevalence of 78.6% (CI = 72.74-83.44) and 100% flock level prevalence of strongyle and coccidia infection among goats from Negeri Sembilan with a higher infection in flock A-Lenggeng (95.6%) than B-Senawang (87.3%), D-Mendom (80.6%), or C-Seremban (60.0%). The co-infections of strongyle + Eimeria (50.6; CI = 44.50 to 56.64) were more common than single infections of either strongyle (16.7%; CI = 12.66 to 21.78) or Eimeria (4.3%; CI = 2.41 to 7.50). Quantitative analysis has revealed different (p < 0.05) patterns of EPG/OPG in various categories of goats. In total, there were 49.8% mild, 8.6% moderate, and 13.6% severe infections of strongyle and 40.1% mild, 6.6% moderate, and 19.8% severe infections of coccidia among goats. The mean PCV of goats with severe strongyle infection (24.60 ± 0.85) was significantly (p < 0.05) lower than the moderate (26.90 ± 1.15), or mild (28.23 ± 0.50) infections and the uninfected (30.4 ± 0.71). There were increased odds of infection with strongyle and coccidia among female (OR = 3.2) and adult (OR = 11.0) goats from smallholder flocks in Negeri Sembilan. In conclusion, gastrointestinal strongyles and coccidia occur at high frequency among smallholder goats, and there is a higher risk of infection amongst the adult and female stock.

    Soil-transmitted helminth (STH) could possibly cause mild to severe health effects such as diarrhea, weakness, intestinal blood loss, and impaired cognitive development and growth. In Malaysia, previous studies depicted a high prevalence rate of STH was due to poor hygiene practice and low efficacies of anthelminthic drugs. This study was conducted to investigate hand hygiene practice and WASH criteria's (Water, sanitation and hygiene) related to STH infection among two indigenous tribes in Peninsular Malaysia. A cross-sectional study was carried out to study the relationship among STH infection compared to water quality, sanitation, and hygiene conditions. A total of 190 individuals from two indigenous villages participated in the study, with ages ranging from 5 to 60 years old. In addition, Pearson's Chisquare (X2) test was utilized to test the relationship among STH with demographic socioeconomic and behavioral factors. The confidence interval (CI) of 95% is used to estimate the precision of the odds ratio (OR). Multivariate logistic regression models were also used to identify the risk factors associated with STH infections. The overall findings indicated a prevalence rate of 72% for STH, and distributed mainly among children aged < 12 years. Furthermore, multivariate analyses using logistic regression revealed chronic health problems, incorrect hand washing, and walking bare footed were associated with STH infection. Overall results indicated high prevalence of STH among the indigenous villagers, which aligns with the published literature and proves to be a problem need to be addressed as neglected disease. Interestingly, there was a significant relationship between the presences of chronic diseases and STH infection, which prompted other questions the awareness needs to be educated and the simple and low-cost intervention on the proper way of hand washing may help to reduce STH infection in these indigenous communities.

    We conducted a cross sectional study to examine the association of intestinal parasitic infections and protein energy malnutrition (PEM) with iron-status indicators and anaemia among Orang Asli children in Selangor, Malaysia. A total of 281 children aged 2 - 15 years were studied. The data were collected using structured questionnaires, anthropometric measurements and laboratory analysis for blood and faecal samples. All children were infected either by A. lumbricoides, T. trichiura or hookworm and almost 19%, 26% and 3% of the children had severe infection of ascariasis, trichuriasis and hookworm infection respectively. The prevalence of giardiasis among them was 24.9%. Overall, 41.5% of the children were anaemic (haemoglobin < 11.0 g/dL). Of these 61.0% of the children had iron deficiency and 36.5% had iron deficiency anaemia (IDA), which accounted for 88.0% of anaemia in this population. Severe trichuriasis had the most significant correlation with anaemia and iron deficiency in this population. It contributed to low concentrations of haemoglobin, serum iron and serum ferritin and high total iron binding capacity (TIBC). Significant underweight and stunting were associated with low concentrations of haemoglobin and serum iron while significant wasting was significantly associated with low concentration of serum ferritin. Logistic regression analysis confirmed that severe trichuriasis was a strong predictor of IDA. It also confirmed that children who were significantly underweight and whose mother was working were independent predictors of IDA in this population.

    The Corona pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) calls on the Saudi government to take action to control the infection. The government closed borders, prohibited travel, limited outdoor movements, and told primary and secondary care facilities to reduce all regular non-urgent health services. It is not known whether these measures have impacted the prevalence of parasitic intestinal infections. This study has therefore been carried out to investigate this issue. Dataset of 217 stool samples submitted to the King Faisal Medical Complex (KFMC) Microbiology Laboratory in Taif, Saudi Arabia for parasitological examination during the pandemic (January-June 2020) and 649 samples submitted during the corresponding months of the previous year (January-June 2019) were extracted and analyzed. Overall, 24.1% (209/866) of samples were parasitespositives; 26.6% (173/649) before and 16.5% (36/217) during the pandemic, with 79% reduction. There was a significant difference in gender-parasitism between the two periods where the majority of parasitism were for males (p<0.001). Infections were frequent in patients aged 5- 14 years both before (84/649; 12.9%) and during (12/217; 5.5%) the pandemic, with significant difference observed between the two cohorts (p<0.002). Moreover, the majority of infected patients were non-Saudi (67.9%; 142/209), with a significant difference in nationality reported, (p=0.024). Protozoa were identified in 21.8% (189) of all samples investigated, of which, Blastocystis hominis, Entamoeba coli, Giardia lamblia, Entamoeba histolytica/dispar and Cryptosporidium species were identified in 6.1% (53), 5.4% (47), 5.0% (44), 2.8% (25), and 2.3% (20), respectively. Helminths were diagnosed in 2.3% (20/866) of samples. Eggs of hookworm, Ascaris, Taenia spp, and Hymenolepis nana were detected in 0.9% (8), 0.5% (5), 0.3% (3) and 0.4% (4), respectively. In parallel with our research hypothesis, a substantial decrease in the burden of intestinal parasitic infections was recorded with the lock-down measures taken during the Corona pandemic.

    PMID: 8074940
    Fecal specimens collected from 456 school children in Gombak, Malaysia, revealed an overall prevalence rate of 62.9%. The most common parasite found was Trichuris trichiura (47.1%) followed by Giardia intestinalis (14.7%), Entamoeba coli (11.4%), Entamoeba histolytica (9.9%) and Ascaris lumbricoides (7.9%). Infection rates were high among the Indonesian immigrant workers' children (90%) followed by the Orang Asli (79.5%), Malay (59.4%) and Indians (36.4%). Females (66.3%) had a higher prevalence rate than the males (58.5%). The prevalence of infection was found to be associated with the socio-economic status, water supply, sanitary disposal of feces and family size. Albendazole administered as a single dose (400 mg) was found to be effective against Ascaris (100%) and hookworm (92.3%) but was not effective against Trichuris (39.2%).

    Soil-transmitted helminthiasis is a common problem in communities with poor socio-environmental conditions. This study was undertaken to identify important socio-environmental predictors of soil-transmitted helminthiasis in Bachok, a rural community in Kelantan for the development and implementation of an effective prevention and control program. Of 363 children randomly sampled, 38.8% were infected with soil-transmitted helminthiasis. Risk predictors of soil-transmitted helminthiasis found to be significant after adjustment included poor household hygiene score and large household size. The probability of being infected was 0.58 amongst children with both of these risk factors.

    Currently, information on prevalence of soil-transmitted helminth (STH) infections among different tribes of Orang Asli (aboriginal) is scarce in Malaysia. The present study is a cross-sectional study aimed at determining the factors associated with the prevalence of STH infections among the Proto-Malay, Negrito and Senoi tribes. Faecal samples were collected from 500 participants and socioeconomic data was collected via pre-tested questionnaire. All samples were processed using formalin-ether sedimentation and Wheatley's trichrome staining. Trichuris trichiura (57%) was the most common STH seen among the participants, followed by Ascaris lumbricoides (23.8%) and hookworm (7.4%). Trichuriasis and ascariasis showed an age-dependency relationship; significantly higher rates were observed among Senois who aged <15 years. Likewise, Negritos also showed an age-dependency association with ascariasis affecting mainly the under 15 years old individuals. Multivariate logistic regression model indicated the following predictors of trichuriasis among these communities; being aged <15 years, consuming raw vegetables, belonging to a large household members (≥8) and earning low household income (
