Global prevalence of enterobiasis in young children over the past 20 years: a systematic review and meta-analysis. Osong Public Health Res Perspect 2023; 14:441-450. [PMID: 38204424 PMCID: PMC10788413 DOI: 10.24171/j.phrp.2023.0204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 10/18/2023] [Accepted: 11/05/2023] [Indexed: 01/12/2024] Open
Abstract
Parasitic infections are the most common diseases worldwide, and enterobiasis is a common parasitic infection in children. Various studies have reported on the prevalence of Enterobius vermicularis in different regions of the world. However, no study has gathered and analyzed this data systematically. Our systematic review and meta-analysis investigated the overall prevalence of E. vermicularis among children globally. Data were extracted from 4 available databases for studies published from January 2002 to April 2022. The quality of the included studies was scored based on the standard Strengthening the Reporting of Observational Studies in Epidemiology. A random-effect model was chosen to calculate the pooled prevalence and corresponding 95% confidence interval (CI) according to the degree of heterogeneity in the included studies. Thus, 40 publications (42 data sets) that included 3,279 children with enterobiasis met all criteria and were included in the analysis. The meta-analysis showed that heterogeneity among the included studies was high (Q=4,399.35, I2=99.96%; df=41; p<0.001). The pooled global prevalence of enterobiasis among the studied children was 12.9% (95% CI, 8.2%-17.7%). Our systematic review and meta-analysis estimated that, for the past 20 years, 12.9% of children around the world have been infected with E. vermicularis.

Abstract
Enterobiasis is a highly infectious parasitic disease spreading worldwide including Yemen. Therefore, this study aimed to investigate the prevalence and risk factors of enterobiasis among Yemeni children in Dhamar governorate. A total of 402 children (aged 1-12 years) participated in this cross-sectional survey carried out at Thamar University Al-Wahdah Teaching Hospital (TUWTH), between 2018 and 2019. Enterobius vermicularis infection was examined using the adhesive tape technique. Association between risk factors and enterobiasis were measured by prevalence ratio (PR). The overall prevalence of enterobiasis was found to be 29.4% (118/402). Risk factors that showed independent association with the infection were child's care responsibility (PR = 1.90; 95% CI = 1.37-2.63; P = 0.001); irregular washing hands before meals (PR = 2.01; 95% CI = 1.32-3.05; P = 0.003); habit of nail biting or cutting by teeth (PR = 1.61; 95% CI = 1.18-2.21; P = 0.002); habit of putting toys or pen in mouth (PR = 1.58; 95% CI = 1.19-2.10; P = 0.002); frequent anal itching (PR = 1.46; 95% CI = 1.10-1.93; P = 0.016); using anthelmintic during the last six months (PR = 1.68; 95% CI = 1.20-2.36; P = 0.011); and parents have no knowledge on preventive measures (PR = 1.62; 95% CI = 1.04-2.53; P = 0.036). Prevalence of enterobiasis among Yemeni children in Dhamar governorate is high with higher infection rate among those aged 1-6 years. Health education and mass treatment are highly recommended among this poor population.

[PMID: 34470095 PMCID: PMC8413852 DOI: 10.3347/kjp.2021.59.4.421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 08/03/2021] [Indexed: 11/23/2022]
Abstract
A 12-year nationwide survey (2008-2019) was performed to investigate the prevalence of Enterobius vermicularis infection among preschool children in Seoul, 4 large cites (Busan, Incheon, Daegu, and Ulsan), and 9 provinces (grouped into 5 localities) in the Republic of Korea (=Korea). The survey was carried out once a year by 16 regional offices of the Korea Association of Health Promotion. The cello-tape perianal swab method (1 smear per child) was applied to detect eggs of E. vermicularis and other helminths. According to the results, the egg positive rate of E. vermicularis infection in 2008-2009 was 1.8-2.0%, but it decreased gradually to 0.6% in 2019 (P<0.05). The prevalence was significantly higher in boys (0.7-5.0%, mean 1.8%) than in girls (0.5-2.8%, mean 1.3%) (P<0.05). The 2 most southern localities, Jejudo (Province) and Jeolla-do (inclusive of Jeollabuk-do and Jeollanam-do) and a mid-western province, Gyeonggi-do, revealed higher prevalences, whereas Seoul and Gangwon-do showed lower prevalences. The results indicate that a low-grade prevalence of E. vermicularis infection (less than 4%) has been maintained for the recent 12 years among preschool children in Korea. Continuous monitoring of enterobiasis in the child age group is necessary in Korea.

The neglected role of Enterobius vermicularis in appendicitis: A systematic review and meta-analysis. PLoS One 2020; 15:e0232143. [PMID: 32324817 PMCID: PMC7179856 DOI: 10.1371/journal.pone.0232143] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Accepted: 04/07/2020] [Indexed: 01/13/2023] Open
Abstract
Although the main cause of appendicitis is unclear, infection with Enterobius vermicularis is suggested as a neglected risk factor. Since, there is no comprehensive analysis to estimate the prevalence of E. vermicularis in appendicitis; therefore, we conducted a global-scale systematic review and meta-analysis study to estimate the prevalence of E. vermicularis infection in appendicitis cases. PubMed, Scopus, Web of Science and Google Scholar databases were systematically searched for relevant studies published until 15 August 2019. Pooled prevalence of E. vermicularis infection was estimated using the random effects model. Data were classified based on the continents and countries. Moreover, subgroup analyses regarding the gender, the human development index (HDI), and income level of countries were also performed. Fifty-nine studies involving 103195 appendix tissue samples belonging to the individuals of appendicitis were included. The pooled prevalence of E. vermicularis infection was (4%, 95%CI, 2–6%), with the highest prevalence (8%, 95% CI: 0–36%) and lowest prevalence (2%, 95% CI: 1–4%) in Africa and Americas continents, respectively. With respect to countries, the lowest and highest prevalence rates were reported from Venezuela (<1%, 95% CI: 0–1%) and Nigeria (33%, 95% CI: 17–52%), respectively. Indeed, a higher prevalence was observed in females, as well as in countries with lower levels of income and HDI. Our findings indicate the relatively high burden of E. vermicularis infection in appendicitis cases. However, our findings suggest the great need for more epidemiological studies to depth understand overlaps between E. vermicularis infection and appendicitis in countries with lower HDI and income levels.

Abstract
Helminth infections caused by Enterobius vermicularis have a cosmopolitan character and most often affect the paediatric pre-school and school age population. The presented study was conducted to determine the prevalence of E. vermicularis in the analyzed population of children in the Eastern Slovakia. The Graham’s scotch tape method was used to investigate the presence of Enterobius vermicularis eggs in 390 specimens. The analyzed set consisted of 218 girls and 172 boys, divided by age into three groups – aged from 5 months to 2 years, aged from 3 to 6 years, and aged from 7 to 15 years. Investigation of perianal scotch tapes of children for the presence of E. vermicularis eggs revealed the prevalence of E. vermicularis was P = 3.59 %. Depending on the incidence of E. vermicularis infection, we detected no statistically significant difference (p> 0.05). The prevalence of E. vermicularis in boys was P = 4.07 %, and in girls P = 3.21 %. The highest prevalence of E. vermicularis was recorded in the group of children aged from 3 to 6 years (P = 5.03 %). Most of the samples were positive at age 4 and 5. The lowest prevalence was in the group of children aged from 5 months to 2 years (P = 0.97 %), and the prevalence of E. vermicularis in the group of children aged from 7 to 15 was P = 3.91 %. The difference in the incidence of E. vermicularis infection among different age groups of children was not statistically significant (p> 0.05). Enterobius vermicularis nematode infection and enterobiasis currently represents a major public health problem in Slovakia. At the present its occurrence is the most frequent in the paediatric population. Therefore it is important to introduce a targeted hygienic-epidemiological measure in children’s collectives, what also should include proper and effective diagnostics and frequent recurrent therapy.

Abstract
Objectives We investigated the prevalence and risk factors for Enterobius vermicularis in children at the Thaklong Municipal Early Childhood Development Center (TMECDC), and the Rangsit Babies’ Home (RBH) in Pathum Thani, Thailand using the Scotch tape method. Results 397 children aged 3–6 years were sampled (male = 198); 31 (7.8%) were E. vermicularis positive: 1 (TMECDC) and 30 (RBH). 264/397 (66.50%) of parents had incomes > 12,000 baht/month and 313/397 (78.84%) were educated from primary school to college. Univariate analysis identified (i) age 5–6 years, (ii) female sex, (iii) lower education of mother/father, (iv) being a house wife, (v) being a low income family, (vi) being resident in the orphanage, (vii) reporting anorexia and/or fever, and (viii) not washing their bottoms as factors for a positive slide. By logistic regression, education level and age group were independently associated with a positive Scotch tape result. Older children and higher family education had opposing associations with E. vermicularis. Strategies to control pinworm infection should focus on high-risk children in orphanages.

Abstract
Objectives Enterobius vermicularis is a parasitic disease that is common in crowded areas such as schools and kindergartens. Primary investigations of electronic evidence have reported different prevalences of E. vermicularis in Iran. Therefore, we aimed to estimate the total prevalence of this infection among Iranian children using a meta-analysis. Methods Relevant studies were identified in national and international databases. We selected eligible papers for meta-analysis after investigating titles, abstracts, and full texts; assessing study quality; and applying inclusion/exclusion criteria. Data were extracted by two independent researchers. The results were combined using a random effects model in Stata v. 11 software. Results Among 19 eligible articles including 11,676 participants, the prevalences of E. vermicularis among all children, boys, and girls were 1.2%–66.1%, 2.3%–65.5%, and 1.7%–65.5%, respectively. Pooled prevalences (95% confidence interval) of E. vermicularis among all children, boys, and girls were 17.2% (12.6%–21.8%), 17.2% (12.6%–21.8%), and 16.9% (9.03%–24.8%), respectively. Conclusion This meta-analysis showed that a great majority of Iranian children are infected with E. vermicularis, possibly due to poor public health.

Abstract
Enterobius vermicularis or pinworm, is considered as one of the most frequently encountered intestinal nematodes and infects millions of people throughout the world particularly children. Some symptoms of the infection including Anal itching, restlessness, insomnia, endometritis, abdominal cramps, diarrhea and etc. The purpose of the present study was to determine the status of enterobiasis in kindergarten and preschool children of kindergartens from Amir Kola, Babol Mazandaran Province, North of Iran. A total number of 126 (70 boys and 56 girls) children from four kindergartens from Amir Kola, Babol, Mazandaran Province, North of Iran were examined for the prevalence of E. vermicularis infection, 2013. Adhesive cello-tape anal swab method was trained to parents for sampling. In addition, a questionnaire was designed and filled out to collect demographic information for each individual. Data were analyzed using Chi square test and multivariate logistic regression for each risk factor. The overall prevalence of E. vermicularis infection was 22.2 % (28). Infection with E. vermicularis in girls 23.2 % was higher compared to boys 21.4 %. Regarding age of examined individuals, infection was seen more both in boys and girls with the age of 6 years old compared to other age groups. There was no significant difference between gender and age (p < 0.05). Based on the results of current study, prevalence of E. vermicularis in kindergarten and preschool children is high and still is an important public health matter in the north of Iran and should not be underestimated due to being highly contagious infection. Therefore, a systematic control and preventive measures should be adopted to reduce morbidity associated with enterobiasis.

Abstract
Although health education has proven to be cost-effective in slowing the spread of enterobiasis, assessments of the effectiveness of health education to reduce infectious diseases specifically in children are rare. To evaluate the effect of health education on knowledge, preventative practices, and the prevalence of enterobiasis, 319 children from 16 classes were divided into experimental and control groups. Data were collected from May 2012 to March 2013. A 40-minute in-class talk was given once in the experimental group. There were significant differences over the time in the mean scores for children's knowledge of Enterobius vermicularis infection in the intervention group compared to the control group (p<0.001). After the educational session, the score for knowledge about E. vermicularis infection increased from 60.2 ± 2.32 to 92.7 ± 1.19 in the experimental group; this gain was partially lost 3 months later, decreasing to 83.6 ± 1.77 (p<0.001). Children's enterobiasis infection prevention practice scores also increased, from 3.23 ± 0.27 to 3.73 ± 0.25, 1 week after the educational session, a gain that was partially lost at 3 months, decreasing to 3.46 ± 0.36 (p<0.001). The overall E. vermicularis egg detection rate was 4.4%; the rates for each school ranged from 0% to 12.9% at screening. The infection rate at 3 months after the treatment sharply decreased from 12.3% to 0.8% in the experimental group, compared to a decrease from 8.5% to 3.7% in the control group during the same period. We recommend that health education on enterobiasis be provided to children to increase their knowledge about enterobiasis and improve prevention practices.

Abstract
Pinworm infection can occur through contact with contaminated surfaces followed by ingestion or even through inhalation of infective eggs. We have limited information regarding environmental contamination by eggs of Enterobius vermicularis. In order to determine environmental risk factors associated with the rate of E. vermicularis infection, we investigated possible environmental risk factors using a questionnaire from 46 kindergartens in 3 different cities of the southeast area of Korea. In total, using the cellotape anal swab technique, 3,422 children were examined for E. vermicularis infection. We evaluated E. vermicularis egg of books, educational materials, toys, room door handles, dusts of window edges, desks, chairs, tables, and dusts of classrooms. The overall egg-positive rate for E. vermicularis was 6.0%, and the prevalence of enterobiasis in each kindergarten ranged between 0% and 16.9%. We found that 78.9% of egg positive kindergartens were managed by private foundations, which was significantly higher, compared with kindergartens managed by public foundations or the nation. Compared with public or national kindergartens, most private kindergartens were located in residential areas and the number of children in these areas was significantly higher. In conclusion, numbers of children in kindergartens was found to be an environmental risk factor associated with transmission of enterobiasis in Korea.

[PMID: 22949757 PMCID: PMC3428575 DOI: 10.3347/kjp.2012.50.3.259] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/08/2012] [Revised: 05/15/2012] [Accepted: 05/28/2012] [Indexed: 11/23/2022]
Abstract
We assessed the prevalence of Enterobius vermicularis infection and changes in the egg positive rate (EPR) over 1-year time, using the adhesive cellophane-tape perianal swab method in 2,347 preschool children in Muan-gun, Jeollanam-do, Republic of Korea in 2008 and 2009. The overall EPR for E. vermicularis was 4.1% in 2008 and 4.5% in 2009. A study population of 389 children was repeatedly examined for 2 years. Within this group, the EPR in 2009 was twice higher than in 2008, and the EPR of the group of 5-7-year-old children was significantly higher than that of other age groups. Moreover, in the group of 5-7-year-old children in 2009, the rates of positive and negative conversion were significantly higher and lower, respectively, than in other age groups. Conclusively, enterobiasis was prevalent during 2008-2009 among preschool children in Muan-gun, Jeollanam-do, and the increased EPR in 2009 was due to an increase in newly acquired infections among 5-7-year-old children.

Impact of health education on the prevalence of enterobiasis in Korean preschool students. Acta Trop 2012; 122:59-63. [PMID: 22172595 DOI: 10.1016/j.actatropica.2011.11.017] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2011] [Revised: 11/26/2011] [Accepted: 11/29/2011] [Indexed: 11/24/2022]
Abstract
Health education has been shown to be effective in slowing the spread of the disease, infectious disease in particular. To evaluate the impact of health education on the prevalence and pattern of new infection of enterobiasis, children from 6 kindergartens in Ulsan city, South Korea, were recruited after undergoing a screening for enterobiasis, and then divided into three groups, including group medication (GM), education (Edu), and control group. All children in GM group received medical treatment with 500 mg albendazole twice, with 15 days interval. In the Edu group, only children diagnosed positive for Enterobius vermicularis eggs received medical treatment with 500 mg albendazole twice, with 15 days interval and all parents in the group received brochures providing information about enterobiasis. In the control group, only children diagnosed positive for E. vermicularis eggs received medical treatment with 500 mg albendazole twice, with 15 days interval, and no information about enterobiasis was provided to parents. Two post-treatment examinations were performed at three and six months after treatment. The infection rate in the GM group was dramatically decreased at 3 months, and this rate was almost the same as at 6 months after treatment. Infection rate of children in the Edu group was shown to drop from 9.9% to 3.0% at 3 months, and to 2.7% at 6 months after treatment; however, the infection rate in the control group continued to be higher than in the other two groups at both 3 and 6 months, with smaller change at 3 months compared to the other two groups. In addition, both new infection and re-infection cases in the Edu group were fewer, compared to those in the control group. In conclusion, although GM is the best method for eradication of enterobiasis, providing health information about enterobiasis to parents could reduce the prevalence, as well as the rate of new infection or re-infection with E. vermicularis in their children.

Abstract
This survey was performed to investigate and compare egg positive rates (EPRs) of Enterobius vermicularis among preschool children in 3 Korean localities (Chuncheon-si, Inje-gun, and Paju-si) in 2008. A total of 7,048 preschool children were examined. Overall, the total EPR was 4.0%; the EPR was the highest in Chuncheon-si (5.6%), followed by Inje-gun (4.5%) and Paju-si (3.4%). The EPR of boys (4.9%) was higher than that of girls (3.1%). The EPR significantly increased with age, with the highest observed in 5~7-year-olds. These findings demonstrate that E. vermicularis infection is widely prevalent among preschool children in Chuncheon-si, Inje-gun, and Paju-si, Republic of Korea.

Abstract
The present study was performed to determine the prevalence of Enterobius vermicularis among preschool children in Gimhae-si, Korea. A total of 6,921 preschool children in 76 kindergartens were examined using the cellotape perianal swab method. The overall egg positive rate (EPR) was 10.5%. The EPR in boys was higher than that in girls (adjusted odds ratio [AOR]: 1.5, P<0.001), and it was higher in rural than in urban children (AOR: 1.2, P=0.022). The present study confirmed that the prevalence of E. vermicularis infection is fairly high among preschool children in Gimhae-si. Therefore, systematic control and preventive measures should be adopted to reduce morbidity associated with this nematode infection.

Abstract
To know the prevalence of Enterobius vermicularis infection and what are the most important risk factors, we evaluated the incidence and risk factors of enterobiasis among children attended in kindergartens in Busan metropolitan city, Republic of Korea. A total of 1,674 children from 21 kindergartens in 11 of 16 autonomous districts of Busan were evaluated for E. vermicularis infection by the cellotape anal swab technique. The overall egg-positive rate for E. vermicularis was 10.7% (179/1,674), and the prevalence of enterobiasis in each kindergarten ranged between 0% and 32.4%. There was an increasing tendency of the egg positive rate according to the population density; the higher the population density communities had, the higher egg-positive rate for E. vermicularis was detected (P = 0.001). Among personal hygiene factors involving children, thumb-sucking (P = 0.036) and fingernail-trimming (P = 0.024) were highly associated with enterobiasis. In addition, taking anthelmintic medications against E. vermicularis infection was strongly associated with enterobiasis (P = 0.014). Moreover, parents' knowledge of enterobiasis was correlated significantly with the incidence of enterobiasis of their children (P = 0.006). In conclusion, we need to consider not only personal hygiene but also parents' knowledge about enterobiasis as a factor in order to develop new strategies for elimination or to complete reduction of enterobiasis in Korea.

Prevalence of Enterobius vermicularis Infection among preschool children in kindergartens of Taipei City, Taiwan in 2008. THE KOREAN JOURNAL OF PARASITOLOGY 2009; 47:185-7.

Abstract
The prevalence of Enterobius vermicularis infection among preschool children was reported to be low based on a 5-year screening program in Taipei City, Taiwan. The Taipei City government intended to terminate the E. vermicularis screening program among preschool children. Thus, we were entrusted with confirming whether pinworm infections among preschool children in Taipei City had truly declined. From each of 12 administrative districts 2-3 kindergartens were randomly selected for investigation. In total, 4,349 children were examined, of which 2,537 were boys and 1,812 were girls. The cellophane tape adhered to a glass slide was used, and all examinations were done by certified medical technologists. Results indicated that the overall prevalence rate of pinworm infections was 0.62% (27/4,349). Although the infection rate was higher among boys (0.67%, 17/2,537) than in girls (0.55%, 10/1,812), no significant difference was found (chi(2) = 0.399, P = 0.62). According to the administrative district, the infection rate ranged from no positive cases of E. vermicularis infection in the Xinyi, Zhongzhen, and Wanhua Districts (0%; 0/299, 0/165, and 0/358, respectively), to 0.26% (1/131) in Songshan District, with the highest rate of 1.88% (7/373) in Wenshan District. Because the overall infection rate (0.62%, 27/4,349) in the present study was unchanged compared to that (0.40%, 197/49,541) previously reported in 2005, we propose that regular pinworm screening and treatment programs should be continued in some parts of Taipei City.

Abstract
Enterobius vermicularis is an intestinal nematode of humans. Adults usually have low worm burdens and are asymptomatic. Ectopic infections in the pelvic area or urinary tract rarely occur in women. We report a case of the patient with mild voiding difficulties such as urgency, frequency, nocturia, dysuria, mild low back pain or perineal discomfort. The patient's prostatic secretions showed a large number of inflammatory cells and several eggs. The size and the shape of the eggs identified them as a group of E. vermicularis. On examination we found a soft palpable material which was 5 mm diameter in size and spherical shape. Palpation gave the impression of a tissue than a stone. An incision was performed and a 4 mm long living worm was found. The microscopic examination identified the worm as E- vermicularis. It is an extremely rare manifestation of enterobius vermicularis infection since an intestinal-breeding worm is rarely found in the male genital tract.
