Background: Parasitoses are among the most important problems of most countries especially developing countries. We aimed to detect the situation of intestinal parasitic infections in the Farashband district in Fars Province South of Iran and identify influential factors in the escalation of parasitic diseases and to reduce them. Methods: Overall, 1009 participants from the age of 6 months to 90 years were selected from 3 cities and 15 villages of Farashband district, Fars Province South of Iran from 2015 to 2016. Parasitological methods such as the direct assay method, formalin-ether concentration method, and zinc sulfate flotation were used for diagnosis of worm eggs, cysts, and protozoa trophozoite. Susceptible and protozoan positive samples were stained using the Trichrome staining method. The modified acid-fast staining procedure was conducted for diarrheal samples and the results were used for diagnosis of coccidia. Results: Overall, 313 subjects were infected with at least one intestinal parasite (pathogenic and nonpathogenic). Helminthes infection and protozoan infection were observed in 9 (0.9%) and 304 (30.13%) participants, respectively. Fecal samples of 34 patients with diarrheal feces were used to prepare smears for further examinations using the Ziehl-Neelsen staining method. Examinations showed no infection with coccidia. Conclusion: Helminthes infection has decreased drastically but protozoan infection is still considered a health issue in this region. It is possible to reduce parasitic infections through proper measures such as increasing public awareness and education the public, especially children on health problems with education courses.

 Intestinal parasitic infections have been a major public health burden of developing countries, especially in children. Higher prevalence has been reported among school children, mostly in rural areas of Nepal where water, toilets, hygiene, and sanitation facilities are insufficient. This cross-sectional study was carried out from April to September 2019 to determine the prevalence of intestinal parasitic infections among school-going children1-5 years of Dharan, Nepal, and to assess the associated risk factors. Stool samples were collected in a clean, dry, screw-capped, and wide-mouthed plastic container, kept in an icebox, and transported to the laboratory. Data relating to different risk factors were collected from the parents of 116 participants using a structured questionnaire. The parasites were identified by using the direct wet mount method and formal-ether concentration method. Pearson’s chi-square test was carried out to establish associations between dependent and independent variables using SPSS version 20, and the test considered a greater than < 0.05% as statistically significant with a 95% confidence level. Out of the 116 stool samples, 9 (7.75%) tested positive for the parasitic infections in which 5 (55.5%) were protozoa and 4 (44.45%) were helminths. The prevalent parasites, were Entamoeba histolytica (23%), Hyamenolepis nana (22%), Giardia lamblia (11%), Hookworm (11%), Entamoeba coli (11%), Ascaris lumbricoides (11%), and Intestinal parasitic infections had a significant association with drinking water, bowel syndrome, bathing habit, toilet facility, and washing hands after toilets (p<0.05). Lack of toilets, poor hygiene, and unsafe drinking water were the main risk factors. Improved hygienic practices, safe drinking water, and the use of latrines could lower the rate of parasitic infections.

AbstractBackgroundIntestinal parasitic infections remain of public health concern worldwide, especially among rural and poorest populations as a consequence of precariousness, lack of sanitation, non-availability of potable water and poor hygiene conditions. The present study aimed to better understand the epidemiology of intestinal parasitic infections in rural areas of forested Cameroon.MethodologyA cross-sectional survey was conducted in three Health Areas (Ndelele, Kentzou and Lolo) of the Ndelele Health District (East Region, Cameroon). Information on socio-demographic characteristics, knowledge, attitudes, and practices regarding intestinal parasitic infections were collected using a semi-structured questionnaire. Stool samples were collected and analyzed by the Kato-Katz and formalin-ether concentration techniques to complement simple direct examination.Principal FindingsA total of 406 individuals belonging to three main groups (Kako or Bantu, Baka or Pygmies and Central African Republic refugees) were enrolled in the study. The overall intestinal parasitic infection rate was 74.9%, including 57.2% cases of polyparasitism. Fourteen parasite species were identified, 89.1% being intestinal protozoa and 41.8% belonging to helminths. Infections with helminths were associated with Baka (P < 0.0001). Spring water consumption was associated with hookworm infection (OR = 3.87; P = 0.008). Garbage deposited near houses was positively associated with infection with Giardia lamblia (OR = 3.41; P = 0.003). Polyparasitism was positively linked to washing hand without soap before meal (OR= 11.64; p= 0.002).Conclusion/SignificanceIntestinal parasitic infections exhibited high rates in the Ndelele Health District, especially among indigenous and hard-to-reach populations (Pygmies). Hygiene measures appear as the main drivers sustaining transmission, and targeted strategies should be developed to efficiently fight against these debilitating diseases.Author summaryIntestinal parasitic infections such as soil transmitted helminthiasis and schistosomiasis, remain a public health concern in Cameroon. To better understand the epidemiology of these infections in hard-to-reach populations in rural areas, a cross-sectional study was carried out in three health areas of Ndelele health District in the Eastern-Cameroon. The rate of intestinal parasitic infections was high (74.9%) especially in indigenous populations (Baka-Pygmies) which exhibited high prevalence of soil transmitted helminth infections (83.3%). The study confirmed that the lack of sanitation and poor hygiene largely contribute to the endemicity of intestinal parasitic infections, particularly among indigenous populations. Targeted control strategies seem mandatory to reach these populations and offer them appropriate care to interrupt or reduce the transmission of these diseases.

AbstractBackgroundIntestinal parasitic infections, anemia, and malnutrition are very endemic in resource-limited regions. School-aged children are at greater risk for the disease than any other age group as they are more susceptible to parasitosis, associated undergrowth and anemia. This study is aimed at evaluating the risk factors of intestinal parasitosis, malnutrition and anemia amongst elementary and junior school students in Ghindae area, Eritrea.MethodsA cross sectional study was conducted in 6 schools around Ghindae from February to April 2018. 450 children were randomly selected for analysis and consent was taken from guardians. The pertinent sociodemographic data was collected and anthropometric measurements were carried out to determine the proportion of students with malnutrition, stunting and thinness. Fecal samples were examined by formal concentration technique and blood specimen was collected for the assessment of hemoglobin using hemocue analyzer.ResultsThe overall prevalence of intestinal parasitosis was 45.3%. Protozoa infections (38.2%) were more prevalent than soil-transmitted helminthes infections (10.4%). The presence of different intestinal parasitic infections has statistically significant association with the residence area, washing habits, source of water, types of schools and type of latrine used with (p < 0.05). The prevalence of malnutrition was 37.1% with 18.5% stunting and 21.2% thinness. Malnutrition was in higher prevalence in semi-urban areas outside Ghindae. Students from Embatkala and Dongolo had 4.77 and 2.86 times higher odds of having low BMI for age than their counterpart respectively. The current prevalence of anemia was 12.4%, out of which, 7.6 % had mild while 4.4% of them had moderate anemia and 0.4% were severely anemic.ConclusionThe prevalence of intestinal parasitic infections, especially, protozoan infection was very high in the school children. Stunting was increased rate in rural areas around Ghindae. The prevalence of anemia was regarded as mild health burden. The high prevalence of parasitic infections in these children indicates that the protozoa and helminthes concerned are very common in the environment of these area and results of the risk factors analysis suggest that the transmission is from several routes. Access to clean water and latrines, with some hygiene and sanitation communication activities, in addition to introduction of micronutrient programs could improve health of children in that area.

Abstract Background Intestinal parasitic infections are amongst the most common infections worldwide and have been identified as one of the most significant causes of morbidity and mortality among disadvantaged populations. This comparative cross-sectional study was conducted to assess the prevalence of intestinal protozoan infections and to identify the significant risk factors associated with intestinal parasitic infections in Laghouat province, Southern Algeria. Methods A comparative cross-sectional study was conducted, involving 623 symptomatic and 1654 asymptomatic subjects. Structured questionnaires were used to identify environmental, socio demographic and behavioral factors. Stool specimens were collected and examined using direct wet mount, formalin-ether concentration, xenic in vitro culture and staining methods. Results A highly significant difference of prevalence was found between symptomatic (82.3%) and asymptomatic subjects (14.9%), with the majority attributable to protozoan infection. The most common species in the symptomatic subjects were Blastocystis spp. (43.8%), E. histolytica/dispar (25.4%) and Giardia intestinalis (14.6%) and more rarely Enterobius vermicularis (02.1%), Teania spp. (0.6%) and Trichuris trichiura (0.2%), while in asymptomatic population Blastocystis spp. (8%), Entamoeba coli (3.3%) and Entamoeba histolytica/dispar (2.5%) were the most common parasites detected with no case of helminth infection. Multivariate log-linear analysis showed that contact with animals was the main risk factor for transmission of these protozoa in both populations. Furthermore, living in rural areas was significantly associated with combined protozoan infection in the asymptomatic population, whereas, in the symptomatic population an increasing trend of protozoan infection was detected in the hot season. In addition, Blastocystis spp. and G. intestinalis infection were found to be associated with host sex and contact with animals across the study period. Conclusions Based on these results, several strategies are recommended in order to effectively reduce these infections including good animal husbandry practices, health education focused on good personal hygiene practices and adequate sanitation.

Abstract Background Intestinal parasitic infections are common in rural areas with poor infrastructure and low socioeconomic status. The aim of this study was to estimate the prevalence of selected parasitic infections in marginalized rural areas in the northern part of the Palestinian West Bank Region, using conventional and PCR-based methods, and also to assess risk predictors of infection. Methods A cross-sectional study was conducted on 104 individuals from three rural villages in the Jordan Valley. Stool samples were collected and examined by a battery of tests that included microscopy of wet fecal samples in normal saline with iodine, concentration by ethyl acetate sedimentation and also by zinc sulfate floatation, a conventional PCR and a real-time PCR (qPCR). Risk factors were assessed that included demographic, socioeconomic, and behavioral characteristics. Data on method performance was analyzed by kappa-statistic, Cochrane’s Q, and McNemar post hoc test. Mid-P exact test and odds ratio were used to discern association between outcome and risk predictors. Results The overall prevalence of intestinal parasitic infections was 48% (49/102). The predominant parasites were Giardia lamblia at 37% (37/102) and Hymenolepis nana at 9% (9/102). To concentrate cysts and eggs, sedimentation can be used as an alternative to floatation with a loss of 1% of positive cases. The methods employing PCRs proved crucial as it increased the detected infection rate of G. lamblia approximately three-fold from 13% by the conventional methods to 37% by the qPCR. Multiple infections were present in 13% (13/102) of the study group, which included double (10%) and triple (3%) infections. Regarding the genus Entamoeba, E. dispar and E. coli were detected at rates of 2 and 8%, respectively. While none of the individuals were infected with the pathogenic E. histolytica, E. nana (4%) was detected for the first time in the area. Age was a risk predictor for infection (OR = 2.61, CI 95% 1.05–6.45, P = 0.038). Conclusions The increased prevalence of intestinal parasitic infections in children in marginalized rural areas in Palestine is worrying. The addition of PCR-based methods is important for the diagnosis of such infections as, with cautious interpretation, it increases proficiency and overcomes underestimation and misdiagnosis of cases. Control measures including education on personal hygiene and environmental sanitation, should be introduced to reduce the prevalence of the intestinal parasites and, thus, the infections they cause in this and other areas.

Background. Research studies on determination of risk factors for intestinal parasitic infections and related malnutrition and anemia in various tropical areas are necessary for appropriate preventive resource allocation and cost effective control. This study is aimed at evaluating the prevalence and risk factors of intestinal parasitosis, malnutrition, and anemia amongst elementary and junior school students in Ghindae area, Eritrea. Method. A cross-sectional study was conducted in 6 schools around Ghindae from February to April 2018. 460 children were selected randomly for analysis and consent was taken from guardians. The pertinent sociodemographic data was collected using a pretested questionnaire, and anthropometric measurements were carried out to determine the proportion of students with malnutrition, stunting, and thinness. Fecal samples were examined by formal-ether concentration technique, and blood specimen was collected and analyzed for the assessment of hemoglobin using Hemocue analyzers. The association between predictors and outcome variables were measured with a stepwise logistic regression model. Result. The overall prevalence of intestinal parasitosis was 45.3%. Protozoan infections (38.2%) were more prevalent than soil-transmitted helminthic infections (10.4%). The presence of different intestinal parasitic infections had statistically significant association with the residence area, hand washing habits, source of drinking water, and type of latrine used. The prevalence of malnutrition was 36.9% with 18.5% stunting and 21.2% thinness. Students of rural areas had 2.03 times more odds of having malnutrition. The current prevalence of anemia was 12.4%, out of which 7.6% had mild anemia while 4.4% of them had moderate anemia and 0.4% were severely anemic. Conclusion. The prevalence of parasitic infection among school-age children in Ghindae area was high. Unsafe drinking water sources from streams and springs were among the core problems for increased prevalence along with decreased awareness on personal hygienic and sanitation practices. Undernutrition was widely prevalent among students in Ghindae area. Height for age and BMI for age scores of all participants were found to be below the WHO growth standards. Malnutrition was in higher prevalence in rural areas outside Ghindae, which is attributed to two times higher odds than their counterparts. The magnitude of anemia found in this study is considered a mild public health problem.

Dog parks represent a recent trend in western countries, enabling owners to spend quality time with their pets in a controlled environment. Despite their growing popularity, few studies have been performed to date on these parks to investigate dog intestinal parasitic infections and soil contamination. The present study examined 369 faecal and 18 soil samples collected from 3 dog parks in Greater Lisbon, Portugal. Additionally, 102 interviews were performed with dog owners to assess dog-walking behaviours and parasite risk. In total, 33% of the faecal dog samples were infected with at least one parasitic agent: hookworms (16.5%), Cryptosporidium spp. (11.9%), Giardia spp. (11.4%), Toxascaris leonina (1.1%), Cystoisospora spp. (1.1%), Toxocara spp. (0.5%), and Sarcocystis sp. (0.3%). The soil of all the parks was contaminated with hookworm eggs. This is the first study performed in a European urban area to assess canine faecal contamination and parasitic agents in dog parks. Our results highlight the potential of these parks as a source of transmission for canine parasites, including some with zoonotic potential. Public awareness and effective preventive measures should be promoted to minimise the health-risk impact to both animals and humans, under the scope of environmental and public health.
