Soil-transmitted helminthiasis in Laos: A community-wide cross-sectional study of humans and dogs in a mass drug administration environment

We conducted a community cross-sectional survey of soil-transmitted helminthiasis in humans and dogs in four provinces in northern Laos. We collected and tested human and dog fecal samples and analyzed results against sociodemographic data. The prevalence of Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis was 26.1% (95% confidence interval [CI,1 = 23.7-28.4%), 41.5% (95% CI = 38.8-44.1%), 46.3% (95% CI = 43.3-49.0%), and 8.9% (95% CI = 7.4-10.4%), respectively. We observed strong heterogeneity for helminthiasis by ethnicity, province, and wealth status, which coincided with a risk profile demonstrating that Mon-Khmer persons and the poorest households are highly vulnerable. Necator americanus was the dominant hookworm species infecting humans and Ancylostoma ceylanicum was the only Ancylastoma species detected. Hookworm prevalence in village dogs was 94%, and the dominant species was A. ceylanicum. Necator americanus was also detected in dogs. It appears that dogs have a role in human hookworm transmission and warrant further investigation

THE CORRELATION BETWEEN WORM INFECTIONS AND NUTRITIONAL STATUS AMONG ELEMENTARY SCHOOL STUDENTS

Background: Worm disease is an infectious disease that still becomes a public health problem in Indonesia. Worm can cause a decrease in health, nutrition, intelligence and productivity of the sufferers. Worms as parasitic animals do not only take nutrients in the intestines of children, but they also damage the intestinal wall so that they interfere the absorption of these nutrients, consequently, it will impact on the decreasing of one's nutritional status and cause other complex nutritional problems. Moyudan Health Center is a Community Health Center in Moyudan Sub-District Region which has the highest cases of helminthiasis (worm infection). Therefore, this study aims to determine the relationship between helminthiasis infection and nutritional status.Methods: This was an observational analytic study using a cross-sectional approach. The sample of this study were elementary school students in the work area of Moyudan Health Center with samples of 311 respondents. The sampling technique used by multistage random sampling is the selection of samples consisting of the smallest areas of an area. Faecal examination was carried out by using the direct method and nutritional status assessment was carried out by anthropometric method based on the anthropometric index Body Age Index per Age (BMI / U). Data were analyzed by Fisher's test.Results: The results showed that there were 8 respondents (2.57%) who were positively infected by worms, 28 respondents had underweight nutritional status (9.01%), and 54 respondents had a nutritional status of fat (17.36%). The results of the study showed no correlation between helminthiasis infection and nutritional status (p-value = 0.534).Conclusions: There is no relationship between helminthiasis and nutritional status in elementary school students in the Moyudan Community Health Center Working Area in Sleman Regency with a p-value of 0.534 so that it is concluded that helminthiasis infection does not provide any significant contribution to nutritional status even though cases of helminthiasis still occur in elementary school students. Therefore, it needs more attention from parents, schools and health facilities in dealing with worm problems

STUDY OF HELMINTHIASIS IN ELEMENTARY SCHOOL CHILDREN IN JAMBI CITY

ABSTRACTIntroduction: Intestinal parasitic infection is a major health problem in developing countries,especially in children, which often causes mortality and morbidity. Worms affect one third of theworld's population. School-age children between the ages of 5 and 15 years in most developingcountries are at the highest risk of chronic helminthic infection and worm-related morbidity. This studyaims to determine the prevalence and determinants of helminthiasis in school-age children.Methods: This research is a quantitative study with a cross-sectional design. The research will beconducted at Jambi City Elementary School in August-October 2022. The total sample is 369respondents using a simple random sampling technique.Results: The type of worm eggs found were Ascaris lumbricoides worm eggs. The most gender ismale (50.7%), the most sources of water for cooking and drinking at home are Refill Water (28.2%),the habit of washing vegetables and raw meat with running water is 90.8%, the number of childrenplaying outside the house the most 76.2%, playing sand 75.9%, using sandals 94.5%, habit of bitingnails 9.8%, washing hands after playing 85.6%, consuming worm medicine 53.1%, and still there arehouses that have floors in the form of land as much as 3.3%.Conclusion: The risk factor for helminthiasis in the community is still high. Only some childrenconsume deworming drugs regularly at their own expense. Government intervention is needed inmass deworming treatment for school childrenKeywords: Worms, Elementary School Childre

Ko-infeksi asimptomatik helminthiasis pada pasien tuberkulosis paru di Surabaya kota: studi pendahuluan

BACKGROUNDPulmonary tuberculosis (TB) is a leading cause of morbidity and mortality, and East Java province is the second largest contributor of co-infection in Indonesia. Asymptomatic helminth infection among pulmonary tuberculosis patients causes another public health problem. Few data relate to helminth infection based on clinical and immunological outcomes of pulmonary TB in highly endemic areas. METHODSThis study was designed as a preliminary study and aimed to determine helminth co-infection among TB patients with a macroscopic assessment. This cross-sectional study was conducted in June-August 2017. RESULTSAmong 16 treated active TB patients from TB cohort data of Tanakali Kedinding health center found that 56% were stool smear-positive for Trichuris trichiura eggs, but had no clinical symptoms. CONCLUSIONWhether or not the helminth infection may have an impact on the diagnosis and treatment of active TB remains to be further investigated. Co-infection could be inhibited by the host immune response and improve the prognosis of TB treatment.LATAR BELAKANGPenyakit tuberculosis paru (TB) hingga saat ini masih menjadi penyebab utama tingginya angka morbiditas dan mortalitas, dan propinsi Jawa Timur termasuk penyumbang penderita kedua terbanyak di Indonesia. Hanya sedikit data informasi diketahui terkait infeksi kecacingan yang terjadi pada penderita TB baik secara klinis dan imunologi pada daerah endemis. METODEStudi ini di desain sebagai studi awal dan bertujuan untuk menilai ko-infeksi kecacingan diantara penderita TB. Studi potong-lintang ini dilakukan pada bulan Juni-Agustus 2017.HASILEnam belas penderita aktif TB berdasarkan data kohort tuberkulosis Puskesmas Tanakali Kedinding, didapatkan 56%-nya positif kecacingan dengan ditemukannya telur Trichuris trichiura.KESIMPULANWalaupun efek dari infeksi kecacingan tidak berdampak terhadap diagnosis dan pengobatan tuberkulosis, akan tetapi sebaiknya penderita yang terdeteksi sebagai tuberkulosis aktif, dilakukan skrining kecacingan terlebih dahulu. Ko-infeksi dapat dihampat oleh respon imun penderita dan meningkatkan prognosis pengobatan tuberkulosis.&nbsp

A first nation-wide assessment of soil-transmitted helminthiasis in Fijian primary schools, and factors associated with the infection, using a lymphatic filariasis transmission assessment survey as surveillance platform

Background Soil-transmitted helminthiasis (STH) is endemic in Fiji but its prevalence is not known and likely to have changed after a decade of mass drug administration (MDA) for lymphatic filariasis (LF). By linking with LF transmission assessment surveys (LF-TAS), we undertook the first nation-wide assessment of STH in Fijian primary schools, as well as an analysis of factors associated with STH infections. Methodology/Principal findings A cross-sectional assessment for STH was conducted in all four Divisions of Fiji from 2014 to 2015. In the Western, Central, and Northern Divisions, schools were sub-sampled after LF-TAS, while, in the Eastern Division, schools were selected via simple random sampling. For the diagnosis of STH, stool samples were examined by coproscopy with a single Kato-Katz thick smear (KK) and the formol-ether-acetate concentration technique, except for the samples from the Eastern Division where only KK was used. Mean prevalence of any STH among class 1–2 students at the national level was 10.5% (95% CI: 6.9–15.5). Across the three Divisions via LF-TAS, the prevalence levels for ascariasis were 8.7% (95% CI: 4.3– 16.6), hookworm 3.9% (95% CI: 2.3–6.6) and trichuriasis 0%. In the Eastern Division, ascariasis prevalence was 13.3% (95% CI: 6.4–25.6), and hookworm 0.7% (95% CI: 0.2–2.5), with one case of trichuriasis. Among class 3–8 students, ascariasis prevalence was lower. Lower risk of any STH was associated with wearing shoes (adjusted OR 0.54, 95% CI: 0.32–0.90) and having piped water from the Fiji Water Authority at home (adjusted OR 0.48,95% CI: 0.25–0.92). Conclusions After a decade of community-based LF-MDA, STH in school-age children in Fiji is now close to 10%, but localities of endemicity remain. Preventive chemotherapy should be maintained in areas with elevated STH prevalence alongside targeted delivery of integrated WASH interventions. LF-TAS has provided an opportunity to develop future public health surveillance platforms

The Policy of Helminthiasis Control and Public Knowledge Againts Helminthiasis in Banjar Regency South Kalimantan Province

Background: Helminthiasis is a neglected disease that lack of attention both prevention and handling. Eventhough helminthiasis is tent not to be deadly disease but it can reduce the nutrition that influence the growth and mental of the children. For the adult it brings out the reducing of productivity. That's why it is very important to determine helminthiasis prevention strategies in South Kalimantan by doing a comprehensive effort to be the basic data for determining policies to helminthiasis control programs appropriatly. This study is aimed to know the specific aspects that retart the program of helminthiasis control in Banjar Regency, South Kalimantan. Methods: It is descriptive study with cross sectional design. The data are collected by indepth interview to the policy holder that has connection with the helminthiasis control and the guardian of elementary schoo, they are 291 respondents. results: There has not any coordination yet between cross programs and sector to control helminthiasis and there has not any budget yet for helminthiasis program. Those are one of the obstruction that make helminthiasis program can not wotk effectively. The public knowledge of Banjar Regency about helminthiasis is in good level. There is no relationship between parental knowledge with helminthiasis, otherwise there is relationship between knowledge of children with helminthiasis. conclusion:Policy only focus on curative services due to helminthiasis is not a deadly disease. recommendation: Increasing the budget of program and improving the awareness of across sector and program will support helminthiasis control program

Epidemiology and control of soil transmitted helminthiasis and giardiasis in Nigeria- a review

Background: Nigeria is the country with the largest population in Africa. Helminthiasis and giardiasis are endemic in Nigeria, due to poor environmental sanitation, pollution, and contamination of water and soil. However, parasitic infections in Nigeria are not only due to the large number of its population, but also due to its geographic nature which is apt for easy parasitic development and individuals infected are children and they attributed this to the fact that children are very careless of the risk associated with playing in contaminated environments and eating indiscriminately with unwashed hands. Objective: To review the epidemiology of soil-transmitted helminthiasis (STH) and giardiasis in Nigeria and feasible control measures. Methodology: A wide-ranging search of electronic bibliographic databases was performed on the epidemiology and control of soil-transmitted helminthiasis and giardiasis in Nigeria. Twenty three full-length articles were studied comprehensively in order to gather up the information on epidemiology of giardiasis and STHs in Nigeria. Result: the occurrence of STH due to the triad of Ascaris lumbricoides, Hookworm and Trichuris trichiura was observed. The paper also showed that the highest and lowest prevalences of helminthiasis are 89.66% and 9.1% while that of giardiasis are 41.45% and 3.10% respectively. Conclusion: This suggests that soil-transmitted helminthiasis and giardiasis are still endemic in Nigeria and majority of those affected are children younger than 10 years living in rural areas and urban slums
