Hospital utilisation among people born in refugee-source countries : an analysis of hospital admissions, Victoria, 1998–2004

Objective: To investigate whether hospital utilisation and health outcomes in Victoria differ between people born in refugee-source countries and those born in Australia. Design and setting: Analysis of a statewide hospital discharge dataset for the 6 financial years from 1 July 1998 to 30 June 2004. Hospital admissions of people born in eight countries for which the majority of entrants to Australia arrived as refugees were included in the analysis. Main outcome measures: Age-standardised rates and rate ratios for: total hospital admissions; emergency admissions; surgical admissions; total days in hospital; discharge at own risk; hospital deaths; admissions due to infectious and parasitic diseases; and admissions due to mental and behavioural disorders. Results: In 2003–04, compared with the Australia-born Victorian population, people born in refugee-source countries had lower rates of surgical admission (rate ratio [RR], 0.85; 95% CI, 0.81–0.88), total days in hospital (RR, 0.74; 95% CI, 0.73–0.75), and admission due to mental and behavioural disorders (RR, 0.70; 95% CI, 0.65–0.76). Over the 6-year period, rates of total days in hospital and rates of admission due to mental and behavioural disorders for people born in refugee-source countries increased towards Australian-born averages, while rates of total admissions, emergency admissions, and admissions due to infectious and parasitic diseases increased above the Australian-born averages. Conclusions: Use of hospital services among people born in refugee-source countries is not higher than that of the Australian-born population and shows a trend towards Australian-born averages. Our findings indicate that the Refugee and Humanitarian Program does not currently place a burden on the Australian hospital system.

Molecular mimicry: Can epitope mimicry induce autoimmune disease?

Mimicry of host antigens by infectious agents may induce cross-reactive autoimmune responses to epitopes within host proteins which, in susceptible individuals, may tip the balance of immunological response versus tolerance toward response and subsequently lead to autoimmune disease. Epitope mimicry may indeed be involved in the pathogenesis of several diseases such as post-viral myocarditis or Chagas disease, but for many other diseases in which it has been implicated, such as insulin-dependent diabetes mellitis or rheumatoid arthritis, convincing evidence is still lacking. Even if an epitope mimic can support a cross-reactive T or B cell response in vitro, its ability to induce an autoimmune disease in vivo will depend upon the appropriate presentation of the mimicked host antigen in the target tissue and, in the case of T cell mimics, the ability of the mimicking epitope to induce a proliferative rather than anergizing response upon engagement of the MHC-peptide complex with the T cell receptor. B cell presentation of mimicking foreign antigen to T cells is a possible mechanism for instigating an autoimmune response to self antigens that in turn can lead to autoimmune disease under particular conditions of antigen presentation, secondary signalling and effector cell repertoire. In this review evidence in support of epitope mimicry is examined in the light of the necessary immunological considerations of the theory.

Doenças emergentes e condições de trabalho de enfermagem: um estudo de caso durante a pandemia de H1N1 no Rio de Janeiro

As doenças infecto-parasitárias, ainda hoje, em pleno século XXI são responsáveis por uma quantidade generosa de morbidade e mortalidade no Brasil e no mundo. Muitas delas são amplamente influenciadas pelas mudanças climáticas que estão ocorrendo em todo o planeta fazendo com que sua incidência e distribuição geográfica aumentem. A dengue é considerada a principal doença reemergente nos países tropicais e subtropicais. A malária tem forte incidência nos países ao sul do deserto do Saara na África, ocorrendo também em vários países da América do Sul que possuem parte da região Amazônica em seu território. Várias doenças voltam a assolar a população de vários locais como as leishmanioses, a Doença de Lyme, erlichioses entre outras. Em março de 2009 começam a ocorrer os primeiros casos de uma nova doença inicialmente denominada Influenza suína, a qual, levou alguns indivíduos a óbito em Oaxaca, uma cidade mexicana localizada a 400 quilômetros da capital. Rapidamente, a doença se espalhou pelo país e posteriormente, no começo do mês de abril de 2009 já, existiam relatos de casos em vários países. O objetivo geral desta pesquisa é verificar em que medida o cuidado de enfermagem realizado expressou um maior ou menor grau de controle do enfermeiro sobre seu trabalho, apontando para os potenciais riscos (biológicos) de adoecimento e impactos negativos na saúde deste trabalhador. O presente estudo foi desenvolvido por meio de uma abordagem quantitativa com desenho longitudinal e observacional, delineamento de pesquisa não experimental e caráter descritivo. Foi feita a análise observacional nas tendas quanto a sua infraestrutura e posteriormente foi passado um questionário aos enfermeiros pautado em questões sobre o risco biológico que estes estavam sendo submetidos. Faz-se necessário que a cultura do improviso acabe e comece a se pensar em uma nova realidade: as doenças transmissíveis são uma realidade, elas existem e há de ser feito um adequamento de tudo que esteja ligado à área de saúde pensando em um novo contexto. É imperioso que tanto as autoridades como os profissionais revejam e reflitam sobre o que aconteceu, para que os erros do passado possam ficar para trás e não se repitam.

Sensing parasites: proteomic and advanced bio-detection alternatives

[EN] Parasitic diseases have a great impact in human and animal health. The gold standard for the diagnosis of the majority of parasitic infections is still conventional microscopy, which presents important limitations in terms of sensitivity and specificity and commonly requires highly trained technicians. More accurate molecular-based diagnostic tools are needed for the implementation of early detection, effective treatments and massive screenings with high-throughput capacities. In this respect, sensitive and affordable devices could greatly impact on sustainable control programmes which exist against parasitic diseases, especially in low income settings. Proteomics and nanotechnology approaches are valuable tools for sensing pathogens and host alteration signatures within microfluidic detection platforms. These new devices might provide novel solutions to fight parasitic diseases. Newly described specific parasite derived products with immune-modulatory properties have been postulated as the best candidates for the early and accurate detection of parasitic infections as well as for the blockage of parasite development. This review provides the most recent methodological and technological advances with great potential for biosensing parasites in their hosts, showing the newest opportunities offered by modern “-omics” and platforms for parasite detection and control.

Condições de trabalho e saúde do enfermeiro residente no hospital geral: riscos psicossociais

Objetivou-se nesse estudo identificar os fatores de risco psicossocial que o enfermeiro residente encontra-se exposto em unidades especializadas; descrever as repercussões dos fatores de risco psicossocial para a saúde do enfermeiro residente em unidades especializadas e analisar as formas de enfrentamento adotadas pelo enfermeiro residente diante dos riscos psicossociais em unidades especializadas. Pesquisa qualitativa do tipo exploratória descritiva, cujo campo foi um hospital universitário situado no município do Rio de Janeiro. A partir dos critérios de seleção adotados participaram do estudo 20 enfermeiros residentes do 1 e 2 anos, lotados em unidades especializadas (CTI adulto, UTI neonatal, CTI cardíaco, UI clínica, Unidade Coronariana e Unidade de Doenças Infecto Parasitárias). O estudo obedeceu aos aspectos éticos em conformidade com a Resolução 466/12 sendo aprovado pelo Comitê de Ética em Pesquisa (067/2012). Utilizou-se a técnica de entrevista semiestruturada mediante um instrumento contendo em sua primeira parte as características dos sujeitos e na segunda um roteiro com questões abertas que possibilitaram ao residente falar sobre os riscos no ambiente laboral, o modo como era afetado e os mecanismos de enfrentamento adotados. Ao término das entrevistas, realizadas no segundo semestre de 2012 e registradas em meio digital, aplicou-se a técnica de análise de conteúdo, sendo os resultados discutidos a luz da Psicodinâmica do Trabalho. Os resultados evidenciaram que o enfermeiro residente de unidades especializadas encontra-se exposto a inúmeros fatores de risco psicossocial e entre eles: a sobrecarga física e psíquica do trabalho, a ambiguidade de papéis, o relacionamento interpessoal conflituoso, a pouca autonomia, o baixo controle em relação ao processo de trabalho e a precariedade das condições de trabalho. Tais fatores, além de afetarem o processo de formação do residente, acarretam prejuízos a sua saúde física e mental; identificados a partir de queixas como: cansaço, estresse, desgaste, padrão de sono ruim, problemas gastrintestinais, dermatológicos e osteomusculares. Diante do sofrimento no trabalho, o enfermeiro residente elabora estratégias de manejo centradas na emoção (autocontrole, aceitação das responsabilidades, fuga, confronto e resignação) e no problema (negociação, tentativa de solução, suporte social, reavaliação positiva). Concluiu-se que o enfermeiro residente encontra-se exposto a inúmeros fatores de risco psicossocial em unidades especializadas que afetam a sua saúde física e mental. No intuito de concluir a residência e preservar a saúde, o residente elabora estratégias de manejo, que apesar de essenciais não eliminam o sofrimento no trabalho e os problemas vivenciados no dia a dia. Cabe ao órgão formador identificar, monitorar e combater os riscos referidos pelo residente no intuito de promover a capacitação, a satisfação e o bem estar no trabalho, ao se considerar a responsabilidade social pela formação, saúde e inserção do futuro profissional no mercado de trabalho.

Influência das proteínas motoras e CK2 no processo de interação Leishmania braziliensis-macrófago.

O gênero Leishmania é responsável por um grupo de parasitoses que podem variar desde lesões auto-limitadas até severa injúria de tecido. Estes protozoários são parasitos obrigatoriamente intracelulares, tendo o macrófago como célula hospedeira. Durante o processo de fagocitose os macrófagos utilizam a maquinaria presente em seu citoesqueleto, a qual compreende a participação de miosinas e actinas, para a formação do fagossoma. Estas proteínas estão envolvidas em processos como citocinese, tráfego intracelular de organelas e vesículas, podendo interferir com a penetração do parasito. Alguns trabalhos vêm sendo realizados visando analisar a expressão, localização e o papel de miosina e de actina em Leishamania. Estudos associados à participação destas proteínas motoras em processo vitais para a biologia do parasito podem auxiliar na compreensão de seu ciclo e permitir a geração de conhecimentos que apontem novos alvos para intervenções terapêuticas. Uma vez que a miosina é necessária no transporte intracelular, alguns estudos tentam analisar a expressão e a localização intracelular de miosinas na Leishmania. Estudos mostram a presença de atividades cinásicas do tipo CK2 em diversos tripanossomatídeos, ligadas ao crescimento celular, morfologia e infectividade de promastigotas para macrófagos. Desta maneira, como objetivo desta tese temos o estudo da participação das miosinas, actina e CK2 na infectividade da Leishmania braziliensis. Além disso, investigamos a influência destas proteínas na produção de citocinas pelos macrófagos e em sua atividade microbicida. Lipoxina, latrunculina, nocodazol e TBB promoveram uma inibição de, pelo menos, 50% no crescimento de L. braziliensis. A CK2 secretada pelo parasito foi purificada de seu sobrenadante através de coluna de HPLC e a fração 44 mostrou ser a fração correspondente a esta enzima. A lipoxina e o TBB promoveram a inibição da atividade desta enzima ao contrário da latrunculina que forneceu aumento dessa atividade. O pré-tratamento dos parasitos ou dos macrófagos com lipoxina, latrunculina, nocodazol e TBB promoveram uma inibição de cerca de 50% no índice de associação entre Leishmania e macrófagos não-ativados ou ativados por LPS e IFN-γ. Latrunculina e TBB aumentaram a produção de NO em macrófagos não ativados e não infectados enquanto que em macrófagos ativados à exceção do TBB, todas as drogas diminuíram a produção de NO. A liberação de IL-10 foi diminuída após tratamento com todas as drogas em macrófagos não ativados em ausência de promastigotas e ativados em presença do parasito. Para a produção de TNF-α há uma redução significativa em macrófagos ativados não infectados tratados com latrunculina, nocodazol e TBB. Quando ativados e infectados, os macrófagos tratados com lipoxina tiveram a produção dessa citocina aumentada, ao contrário do TBB em que houve redução. Quando avaliamos a integridade da actina verificamos que todos os compostos foram capazes de influenciar a distribuição dessa proteína, levando a uma redução no índice de associação. Ao transfectarmos a cauda da miosina Va fusionada a GFP nos macrófagos observamos que houve uma diminuição de 94% no índice de associação. Nossos dados confirmam a importância da CK2, actina e miosina Va no processo de interação parasito- macrófago.

Identification and characterization of a cathepsin L-like cysteine protease from Taenia solium metacestode

Taenia solium metacestode, a larval pork tapeworm, is a causative agent of neurocysticercosis, one of the most common parasitic diseases in the human central nervous system. In this study, we identified a cDNA encoding for a cathepsin L-like cysteine protease from the T solium metacestode (TsCL-1) and characterized the biochemical properties of the recombinant enzyme. The cloned cDNA of 1216 bp encoded 339 amino acids with an approximate molecular weight of 37.6 kDa which containing a typical signal peptide sequence (17 amino acids), a pro-domain (106 amino acids), and a mature domain (216 amino acids). Sequence alignments of TsCL-1 showed low sequence similarity of 27.3-44.6 to cathepsin L-like cysteine proteases from other helminth parasites, but the similarity was increased to 35.9-55.0 when compared to mature domains. The bacterially expressed recombinant protein (rTsCL-1) did not show enzyme activity; however, the rTsCL-1 expressed in Pichia pastoris showed typical biochemical characteristics of cysteine proteases. It degraded human immunoglobulin G (IgG) and bovine serum albumin (BSA), but not collagen. Western blot analysis of the rTsCL-1 showed antigenicity against the sera from patients with cysticercosis, sparganosis or fascioliasis, but weak or no antigenicity against the sera from patients with paragonimiasis or clonorchiasis.

Developing drugs for developing countries.

Infectious and parasitic diseases create enormous health burdens, but because most of the people suffering from these diseases are poor, little is invested in developing treatments. We propose that developers of treatments for neglected diseases receive a "priority review voucher." The voucher could save an average of one year of U.S. Food and Drug Administration (FDA) review and be sold by the developer to the manufacturer of a blockbuster drug. In a well-functioning market, the voucher would speed access to highly valued treatments. Thus, the voucher could benefit consumers in both developing and developed countries at relatively low cost to the taxpayer.

Epidemiological and nutrition transition in developing countries: impact on human health and development

Whereas common infectious and parasitic diseases such as malaria and the HIV/AIDS pandemic remain major unresolved health problems in many developing countries, emerging non-communicable diseases relating to diet and lifestyle have been increasing over the last two decades, thus creating a double burden of disease and impacting negatively on already over-stretched health services in these countries. Prevalence rates for type 2 diabetes mellitus and CVD in sub-Saharan Africa have seen a 10-fold increase in the last 20 years. In the Arab Gulf current prevalence rates are between 25 and 35% for the adult population, whilst evidence of the metabolic syndrome is emerging in children and adolescents. The present review focuses on the concept of the epidemiological and nutritional transition. It looks at historical trends in socio-economic status and lifestyle and trends in nutrition-related non-communicable diseases over the last two decades, particularly in developing countries with rising income levels, as well as the other extreme of poverty, chronic hunger and coping strategies and metabolic adaptations in fetal life that predispose to non-communicable disease risk in later life. The role of preventable environmental risk factors for obesity and the metabolic syndrome in developing countries is emphasized and also these challenges are related to meeting the millennium development goals. The possible implications of these changing trends for human and economic development in poorly-resourced healthcare settings and the implications for nutrition training are also discussed.

Microtubules as antiparasitic drug targets

Background: Parasitic diseases including malaria, leishmaniasis and schistosomiasis take a terrible toll of human life, health and productivity, especially in tropical and subtropical regions, and are also highly significant in animal health worldwide. Antiparasitic drugs are the mainstays of control of most of these diseases, but in many cases current therapies are inadequate and in some the situation is deteriorating because of drug resistance. Microtubules, as essential components of almost all eukaryotic cells, are proven drug targets in many helminth diseases and show promise as targets for the development of new antiprotozoal drugs. Objective: This article reviews the chemistry of the microtubule inhibitors in current use and under investigation as antiparasitic agents, their activities against the major parasites and their mechanisms of action. New directions in both inhibitor chemistry and biological evaluation are discussed. Conclusions: The most promising immediate avenues for discovery and design appear to lie in development of novel benzimidazoles for helminth parasites and compounds based on antimitotic herbicides for protozoal parasites. New understanding from functional genomics, structural biology and microtubular imaging will help accelerate the development of completely novel antiparasitic drugs targeting microtubules.

Biological control of the fish louse in a rainbow trout fishery

Novel egg-laying boards were found to be effective in the biological control of the freshwater fish louse Argulus foliaceus in a 12.9 ha rainbow trout Oncorhynchus mykiss fishery which had a high prevalence and intensity of infection of juvenile parasites in the early spring of 1999. Approximately 228 000d during an extensive 14 week period of egg laying which peaked in June 1999. In contrast, only 1566 clutches were harvested in 2000, when egg laying activity showed a bi-modal distribution, peaking in May and again in July and August. iaceus on rainbow trout in consecutive years was 2.9 : 1 and 2.1 : 1. Estimates of the size of the female A. foliaceus population based on egg-laying activity in 1999 exceeded that derived from measurements of prevalence and intensity of infection, whereas in 2000, this was more in balance. A minimum temperature of 10 degree C was identified for egg laying, which occurred continuously from May to October in a broadly synchronous manner..

Interaction of malaria parasites with host late endocytic and autophagic pathways is essential for Plasmodium liver stage development

RESUMO: A Malária é causada por parasitas do género Plasmodium, sendo a doença parasitária mais fatal para o ser humano. Apesar de, durante o século passado, o desenvolvimento económico e a implementação de diversas medidas de controlo, tenham permitido erradicar a doença em muitos países, a Malária continua a ser um problema de saúde grave, em particular nos países em desenvolvimento. A Malária é transmitida através da picada de uma fêmea de mosquito do género Anopheles. Durante a picada, os esporozoítos são injetados na pele do hospedeiro, seguindo-se a fase hepática e obrigatória do ciclo de vida. No fígado, os esporozoítos infetam os hepatócitos onde se replicam, dentro de um vacúolo parasitário (VP) e de uma forma imunitária silenciosa, em centenas de merozoitos. Estas novas formas do parasita são as responsáveis por infetar os eritrócitos, iniciando a fase sanguínea da doença, onde se os primeiros sintomas se manifestam, tais como a característica febre cíclica. A fase hepática da doença é a menos estudada e compreendida. Mais ainda, as interações entre o VP e os organelos da células hospedeira estão ainda pouco caracterizados. Assim, neste estudo, as interações entre os organelos endocíticos e autofágicos da célula hospedeira e o VP foram dissecados, observando-se que os anfisomas, que são organelos resultantes da intersecção do dois processos de tráfego intracelular, interagem com o parasita. Descobrimos que a autofagia tem também uma importante função imunitária durante a fase hepática inicial, ao passo, que durante o desenvolvimento do parasita, já numa fase mais tardia, o parasita depende da interação com os endossomas tardios e anfisomas para crescer. Vesiculas de BSA, EGF e LC3, foram, também, observadas dentro do VP, sugerindo que os parasitas são capazes de internalizar material endocítico e autofágico do hospedeiro. Mais ainda, mostramos que esta interação depende da cinase PIKfyve, responsável pela conversão do fosfoinositidio-3-fosfato no fosfoinositidio-3,5-bifosfato, uma vez que inibindo esta cinase o parasita não é capaz de crescer normalmente. Finalmente, mostramos que a proteína TRPML1, uma proteína efetora do fosfoinositidio-3,5-bifosfato, e envolvida no processo de fusão das membranas dos organelos endocíticos e autofágicos, também é necessária para o crescimento do parasita. Desta forma, o nosso estudo sugere que a membrana do VP funde com vesiculas endocíticas e autofágicas tardias, de uma forma dependente do fositidio-3,5-bifosfato e do seu effetor TRPML1, permitindo a troca de material com a célula hospedeira. Concluindo, os nossos resultados evidenciam que o processo autofágico que ocorre na célula hospedeira tem um papel duplo durante a fase hepática da malaria. Enquanto numa fase inicial os hepatócitos usam o processo autofágico como forma de defesa contra o parasita, já durante a fase de replicação o VP funde com vesiculas autofágicas e endocíticas de forma a obter os nutrientes necessários ao seu desenvolvimento.--------- ABSTRACT: Malaria, which is caused by parasites of the genus Plasmodium, is the most deadly parasitic infection in humans. Although economic development and the implementation of control measures during the last century have erradicated the disease from many areas of the world, it remains a serious human health issue, particularly in developing countries. Malaria is transmitted by female mosquitoes of the genus Anopheles. During the mosquito blood meal, Plasmodium spp. sporozoites are injected into the skin dermis of the vertebrate host, followed by an obligatory liver stage. Upon entering the liver, Plasmodium parasites infect hepatocytes and silently replicate inside a host cell-derived parasitophorous vacuole (PV) into thousands of merozoites. These new parasite forms can infect red blood cells initiating the the blood stage of the disease which shows the characteristic febrile malaria episodes. The liver stage is the least characterized step of the malaria infection. Moreover, the interactions between the Plasmodium spp. PV and the host cell trafficking pathways are poorly understood. We dissected the interaction between Plasmodium parasites and the host cell endocytic and autophagic pathways and we found that both pathways intersect and interconnect in the close vicinity of the parasite PV, where amphisomes are formed and accumulate. Interestingly, we observed a clearance function for autophagy in hepatocytes infected with Plasmodium berghei parasites at early infection times, whereas during late liver stage development late endosomes and amphisomes are required for parasite growth. Moreover, we found the presence of internalized BSA, EGF and LC3 inside parasite vacuoles, suggesting that the parasites uptake endocytic and autophagic cargo. Furthermore, we showed that the interaction between the PV and host traffic pathways is dependent on the kinase PIKfyve, which converts the phosphoinositide PI(3)P into PI(3,5)P2, since PIKfyve inhibition caused a reduction in parasite growth. Finally, we showed that the PI(3,5)P2 effector protein TRPML1, which is involved in late endocytic and autophagic membrane fusion, is also required for parasite development. Thus, our studies suggest that the parasite parasitophorous vacuole membrane (PVM) is able to fuse with late endocytic and autophagic vesicles in a PI(3,5)P2- and TRPML1-dependent manner, allowing the exchange of material between the host cell and the parasites, necessary for the rapid development of the latter that is seen during the liver stage of infection. In conclusion, we present evidence supporting a specific and essential dual role of host autophagy during the course of Plasmodium liver infection. Whereas in the initial hours of infection the host cell uses autophagy as a cell survival mechanism to fight the infection, during the replicative phase the PV fuses with host autophagic and endocytic vesicles to obtain nutrients required for parasite growth.

Routine use of point-of-care tests: usefulness and application in clinical microbiology.

Point-of-care (POC) tests offer potentially substantial benefits for the management of infectious diseases, mainly by shortening the time to result and by making the test available at the bedside or at remote care centres. Commercial POC tests are already widely available for the diagnosis of bacterial and viral infections and for parasitic diseases, including malaria. Infectious diseases specialists and clinical microbiologists should be aware of the indications and limitations of each rapid test, so that they can use them appropriately and correctly interpret their results. The clinical applications and performance of the most relevant and commonly used POC tests are reviewed. Some of these tests exhibit insufficient sensitivity, and should therefore be coupled to confirmatory tests when the results are negative (e.g. Streptococcus pyogenes rapid antigen detection test), whereas the results of others need to be confirmed when positive (e.g. malaria). New molecular-based tests exhibit better sensitivity and specificity than former immunochromatographic assays (e.g. Streptococcus agalactiae detection). In the coming years, further evolution of POC tests may lead to new diagnostic approaches, such as panel testing, targeting not just a single pathogen, but all possible agents suspected in a specific clinical setting. To reach this goal, the development of serology-based and/or molecular-based microarrays/multiplexed tests will be needed. The availability of modern technology and new microfluidic devices will provide clinical microbiologists with the opportunity to be back at the bedside, proposing a large variety of POC tests that will allow quicker diagnosis and improved patient care.

Soil-Transmitted Helminths, Poverty, and Malnutrition in Honduran Children Living in Remote Rural Communities

Soil-transmitted helminth (STH) infections are endemic in Honduras, but their prevalence according to the levels of poverty in the population has not been examined. The present cross-sectional study is aimed to determine the role of different levels of poverty in STH prevalence and infection intensity as well as the potential associations of STH infections with malnutrition and anemia. Research participants were children attending a medical brigade serving remote communities in Northern Honduras in June 2014. Demographic data were obtained, and poverty levels were determined using the unsatisfied basic needs method. STH infections were investigated by the Kato-Katz method; hemoglobin concentrations were determined with the HemoCue system; and stunting, thinness, and underweight were determined by anthropometry. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression models. Among 130 children who participated in this study, a high prevalence (69.2%) of parasitism was found and the poorest children were significantly more infected than those living in less poor communities (79.6% vs. 61.8%; P = 0.030). Prevalence rates of Trichuris trichiura, Ascaris lumbricoides, and hookworms were 69.2%, 12.3%, and 3.85%, respectively. In total, 69% of children had anemia and 30% were stunted. Households’ earthen floor and lack of latrines were associated with infection. Greater efforts should be made to reduce STH prevalence and improve overall childhood health, in particular, among the poorest children lacking the basic necessities of life.
