“…histolytica/ dispar in this meta-analysis was 13.3%, which is consistent with the 14.09% rate reported in Ethiopia [ 4 ] and 12.1% in the Philippines [ 78 ]. However, the prevalence rate in the present study was lower than that in studies conducted in Malaysia (20.4%) [ 79 ], Yemen (16.4) [ 80 ] and Tanzania 15% [ 81 ] but higher than that in studies in Bangladesh (3.83%) [ 82 ] and Thailand (3.7%) [ 83 ].…”

Introduction Parasitic infections, especially intestinal protozoan parasites (IPPs) remain a significant public health issue in Africa, where many conditions favour the transmission and children are the primary victims. This systematic review and meta-analysis was carried out with the objective of assessing the prevalence of IPPs among school children in Africa. Methods Relevant studies published between January 2000 and December 2020 were identified by systematic online search on PubMed, Web of Science, Embase and Scopus databases without language restriction. Pooled prevalence was estimated using a random-effects model. Heterogeneity of studies were assessed using Cochrane Q test and I2 test, while publication bias was evaluated using Egger’s test. Results Of the 1,645 articles identified through our searches, 46 cross-sectional studies matched our inclusion criteria, reported data from 29,968 school children of Africa. The pooled prevalence of intestinal protozoan parasites amongst African school children was 25.8% (95% CI: 21.2%-30.3%) with E. histolytica/ dispar (13.3%; 95% CI: 10.9%-15.9%) and Giardia spp. (12%; 95% CI: 9.8%-14.3%) were the most predominant pathogenic parasites amongst the study participants. While E. coli was the most common non-pathogenic protozoa (17.1%; 95% CI: 10.9%-23.2%). Conclusions This study revealed a relatively high prevalence of IPPs in school children, especially in northern and western Africa. Thus, poverty reduction, improvement of sanitation and hygiene and attention to preventive control measures will be the key to reducing protozoan parasite transmission.

“…Similar infection rate (11.0%) was reported from Brazil [ 84 ], and a considerably higher prevalence rate was detected in Nepal (46.8%) [ 85 ]. Meanwhile, the infection rate in Bangladesh (6.01%) [ 82 ] and Thailand (4.9%) [ 83 ] was lower than the present finding. The variations in prevalence rates of E .…”

“…On the other hand, Shreshtha et al have reported 39.7% of IPIs among school children of two schools from central Nepal [18]. Similarly, very high rates of IPIs were reported in school children from different countries [21][22][23][24]. Another study from Morang, a neighbour district of Saptari, reported 83.3% of stool samples with helminth parasites in school children where A. lumbricoides (50.92%) was the most detected parasite followed by Ancylostoma duodenale (44.56%) and Trichuris trichiura, respectively [25].…”

Background: Intestinal parasitosis, caused by both helminths and protozoans, are among the most prevalent infections, especially in developing countries. Enteric parasites continue to be a major cause of parasitic diseases which is the most common among street and school going children with poor sanitation. This cross-sectional study was carried out to determine the prevalence and potential risk factors of intestinal parasitosis among school going children of two schools of Saptari district of southern Nepal. Stool samples were collected in a clean, dry, screwcapped, and wide-mouthed plastic container, fixed with 10% formal-saline solution, and transported to the laboratory for further microscopic analysis by following concentration technique. Results: Out of the 285 stool samples analysed, 94 (33%) were positive for the parasitosis. Presence of intestinal parasites was marginally more in rural school (44.6%) than in urban (30%) (P < 0.05). Giardia lamblia was highly prevalent (15.4%) followed by Entamoeba histolytica-like (7.7%), E. coli (7%), Ascaris lumbricoides (1.8%), and Hymenolepis nana (1.08%), respectively. Children of the age group 11-15 years were highly affected (44.2%) compared to younger age groups. The findings of intestinal parasitosis in the study population were statistically significant with family income, hand-washing habit, type of drinking water, and availability of a toilet facility at home (P < 0.05). Over 85% of infection was associated with parasitosis that indicated mainly waterborne infection rather than soil-borne helminths. Conclusions: Poor hygiene measures and farming occupation are identified as major risk factors of parasitic infections, so sanitation especially focusing on safe drinking water along with multi intervention strategies must be emphasized in the Saptari district of Nepal to reduce the burden of parasitic diseases in school children.

“…A study among pediatric patients (below five years) in a tertiary hospital was done where Giardia cysts were found in 4.14% of cases [ 107 ]. In a slum area of Bangladesh, Giardia duodenalis positive samples were found in 6.01% of cases among school-going children [ 108 ]. In Sikkim, India, a prospective study among symptomatic children (<15 years) was done where Giardia cysts were found in 5% of cases by wet mount [ 109 ].…”

Introduction Gastrointestinal parasitic infections are one of the global health concerns in developing countries like Bangladesh. Among them, Cryptosporidium spp. plays an essential role in causing diarrhea, malnutrition, and poor cognitive function, especially in children. This study was conducted to identify the frequency of Cryptosporidium cases and other parasitic agents. Methods A cross-sectional observational study was conducted among 219 hospitalized children with diarrhea. The conventional microscopic technique was applied for parasitic detection. Particular staining (modified Ziehl-Neelsen) procedure was performed to identify oocysts of Cryptosporidium spp . A polymerase chain reaction (PCR) was performed to determine the SSU rRNA and gp60 gene of Cryptosporidium. Results Cysts of Giardia duodenalis (2.3%), ova of Ascaris lumbricoides (1.4%,), Trichuris trichiura (0.5%), and both A. lumbricoides and T. trichiura (0.9%) were identified in samples through wet mount preparation. The distribution of Cryptosporidium spp. as detected by the staining method and nested PCR was 1.4% and 4.1%, respectively. Conclusion Factors independently associated with Cryptosporidium infection are unsafe water, lack of regular hand washing, and insufficiency of exclusive breastfeeding. This study reports, presumably for the first time, the detection of Cryptosporidium oocysts in Chattogram metropolitan city of Bangladesh.
