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.

Malaria remains a public health concern in Namibia and it is endemic in many regions, including Kavango east region. University students in Kavango east region are at risk of malaria due to bushy environment and the presence of Kavango river, which makes it easy for mosquitoes to multiply. This study aimed to assess and describe knowledge, attitudes and practices of malaria prevention among university students. A quantitative descriptive cross-sectional study was conducted, using a pretested questionnaire to collect data from 239 university students in Kavango east region. A proportionate stratified random sampling was used to sample students from the three faculties on campus. Data were analysed with a Statistical Programme of Social Sciences. The overall response rate was 75% (239) from a total of 318 respondents. Mean age was 21.4 years, respondents comprised of 155 (64.9%) females and 84 (35.1%) males. Almost all respondents (94.5%) know that malaria is transmitted by mosquitoes and 80% of respondents indicated that malaria is preventable. Usage of mosquito net was the most commonly known preventive measure, indicated by 224 (94%) of respondents. The vast majority of respondents 227 (95%) agreed that the appropriate method to prevent self from getting malaria is to prevent mosquito bites. Surprisingly 80 (33%) of the respondents believe that only children and pregnant women get malaria and therefore it&rsquo;s only them who need preventive measures. Only 43 (18%) of the respondents always sleep under mosquito nets to prevent themselves from getting malaria. It was concluded that university students in Kavango east region have good knowledge on malaria prevention measures. Although there were some misconceptions noted, especially on the identification of population at risk of malaria, the attitudes on malaria prevention are generally satisfactory. However, the knowledge and attitudes do not reflect in the students&rsquo; practices.&nbsp;

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.

BACKGROUND: Parasitic infections are widespread in rural areas of West China. The remote and humid environment, traditional ways of life, contaminated potable water and limited health services all contribute to the transmission and persistence of fecal parasites.OBJECTIVE: To describe the prevalence of intestinal parasitic infections in an area of West China, including its associations with demographic variables.METHODS: Single fecal specimens were collected using a previously validated kit. Parasites were detected microscopically by iodine-stained smear, modified Kato-Katz thick smear, simple saline smear, test tube filter paper culture and adhesive cellophane tape anal swab.RESULTS: The prevalence of enteric parasites in the population was 51.7%. The proportion of individuals infected with one parasite was 36.5%, two parasites 12.7%, three parasites 3.0% and four parasites 0.08%. Parasites identified includedAscaris lumbricoidesin 41.4% of all individuals tested,Ancylostoma duodenalein 17.7%,Trichurias trichuriain 8.25%,Enterobius vermicularisin 0.43%,Blastocystis hominisin 1.37%,Entamoeba coliin 0.47%,Entamoeba histolyticain 0.16%,Giardia lambliain 0.04%,Strongyloides stercoralisin 0.04% andClonorchis sinensisin 0.04%. The prevalence was significantly increased in women, people aged 15 to 19 years and over 80 years, the rural farm population, farmers, preschool and primary school groups, residents of a hilly rather than mountainous or plains terrain, and in intermediate income groups. The prevalence was significantly negatively associated with educational level, but not with age or income.CONCLUSIONS: This study supports the use of simple fecal examinations to monitor the parasite burden in rural areas of developing countries. Enteric parasites remain common in this population in rural China.

In 2007, the Philippine government passed the Anti-Rabies Act to address rabies in the country. However, rabies is still a major public health concern in many provinces. This study aimed to evaluate the knowledge, attitude, and practices (KAP) of residents on rabies, the Anti Rabies Act, and responsible pet ownership (RPO) in Pampanga, Philippines. A cross-sectional survey was done from October 2017 to February 2018 in 92 randomly selected barangays in the province. Questionnaires were adapted from similar studies. Logistic regression was used to identify factors associated with KAP. Results showed that most people have good knowledge of the Anti-Rabies Act, RPO, and moderate knowledge of rabies. Their attitude toward rabies was appropriate, and on RPO, moderate. The RPO practices by most dog owners were good and moderate for most cat owners. Moreover, the subjects’ area of residence was a significant factor in their knowledge of RPO, and pet ownership status was a significant factor in their RPO attitude. In general, respondents showed satisfactory knowledge; however, there is a need to intensify information and education campaigns in rural areas.

Background: The current study was aimed to assess the prevalence of intestinal parasitic infections (IPIs) in persons who were referred to selected hospitals of Abadan and Khorramshahr cities, in southwest of Iran. Materials and Methods: In this descriptive cross-sectional study, 43200 and 28821 stool specimens were gathered from Abadan and Khorramshahr cities, respectively, during four consecutive years (2014-2017). Results: A decreasing trend was seen in the prevalence rate of IPIs in Abadan and Khorramshahr cities. The overall prevalence of IPIs were estimated 5.82% and 6.11% in Abadan and Khorramshahr cities, respectively. In Abadan city, the proportion of IPIs in male persons with 56% was higher than females 44%, while in Khorramshahr city, the more prevalence was observed in females (54% vs. 46%). Moreover, according to the season, the highest prevalence were recorded in the Spiring (30.4%) and Summer (31.1%) in Abadan and Khorramshahr cities, respectively. We found Giardia lamblia, as the most frequent parasite in studied individuals of both cities (Abadan: 2.92%; 1261/43200 and Khorramshahr: 3.15%; 908/28821). Other parasites were as follows: Entamoeba histolytica/dispar, E. coli, E. hartmanni, Blastocystis hominis, Hymenolepis nana, Enterobius vermicularis, Strongyloides stercoralis, and Taenia spp. Conclusion: This was the first study on the prevalence of IPIs in Abadan and Khorramshahr cities, southwest of Iran. Intestinal parasites are still the main public health concern in these regions. Health education, improving sanitary conditions, screening and treatment of infected people, particularly in rural and semi-urban areas can be helpful.

Abstract Background This cross-sectional study was carried out in different settlements of Gabon to determine the influence of single or multiple parasite carriage on haemoglobin (Hb) levels. Methods Between April 2015 and June 2016, healthy volunteers from urban, peri-urban and rural areas were screened for malaria, blood filariasis and intestinal parasitic infections using microscopic methods. Hb concentration was measured with a Hemocue analyser. The association between parasite carriage and anaemia was assessed. Results Among the 775 volunteers examined, 319 (41.2%) were from rural villages and 76.0% were adults. Filariasis, intestinal parasitic infections, Plasmodium falciparum and polyparasitism were detected in 15.6, 14.6, 9.5 and 6.8% of participants, respectively. Anaemia prevalence was 72.6%, with rates of mild, moderate and severe anaemia being 30.9, 61.1 and 8.0%, respectively. The median Hb level was lowest in the presence of hookworms (7.1 g/dl [interquartile range {IQR} 6.8–7.5]), Schistosoma intercalatum (6.9 g/dl), Trichuris trichiura (10.1 g/dl [IQR 8.9–11.5]) and Plasmodium falciparum (10.0 g/dl [IQR 9.1–11.2]) compared with filariaemia (12.1 g/dl [IQR 10.5–13.2]) (p=0.03). Moderate to severe anaemia predominated among those single-infected with P. falciparum (69.5%) or co-infected with intestinal parasitic infections and P. falciparum (76.2%), while it was found in only 23.2% of individuals with filariasis. All participants with soil-transmitted helminths and more than half with a Blastocystis sp. (68.8%) infection had moderate anaemia. Conclusions The prevalence of anaemia is high. Asymptomatic parasite carriage is associated with anaemia in this surveyed population in Gabon.

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 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.

Background: Intestinal parasitic infections are the one of the most common health problems in developing countries. Objective: A number of patients die annually due to complications caused by these parasites.Therefore, the aim of this study was to investigate the rate and type of parasitic infections, determine the factors affecting them in Ilam city and also provide strategies to prevent them.In this descriptive cross-sectional study conducted in one of the Ilam labs in 2016, 417 stool specimens were randomly collected. All specimens were examined using direct and ethanol formaldehyde.Suspect specimens were examined using Trichrom staining. Demographic information was also recorded in a questionnaire, and finally the results were analyzed using statistical software SPSS 20.The data were then compared with Chi-square test. Results: Out of the 417 patients examined, 59 (14.1%) were infected with intestinal parasites. The type of parasitic infection in 9.4% was Blastocystis hominis, 3.6% Entamoeba coli, 0.5% Entamoeba histolytica, 0.5% Giardia and 0.2% Trichomonas hominis. Conclusion: Despite the improvement of public health, parasitic infections are still considered as one of the health problems in the city of Ilam. Therefore, proper planning, public health education, raising the level of health in the area and the provision of safe drinking water are some of the ways to reduce parasitic infections in the region.

Malnutrition is a major public health concern in Niger. The stunting rate in children in Niger is over 50%, one of the highest in the world. The purpose of this cross-sectional study was to examine children’s dietary diversity (CDD) and the maternal factors that impact CDD. A total of 1265 mother–child pairs were analyzed. Descriptive analysis was conducted to present maternal and child characteristics. To compare the mean scores of CDD in relation to the region, an independent sample t-test was conducted. A one-way ANOVA test was conducted to evaluate the CDD score by different age groups. A linear regression model was estimated to identify household, maternal and child factors that affect the CDD score. Our results indicate that most of the participants of our survey resided in rural areas and the majority (80.7%) of the mothers had no education. Factors such as region, children’s age, woman’s empowerment, vitamin A intake and wealth index were significant predictors of CDD (p < 0.05). The children residing in rural areas were more likely to have lower CDD scores (p < 0.05) than the children in urban areas, therefore becoming more susceptible to malnutrition.

 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.
