Abstract. Post-treatment soil-transmitted helminth re-infection patterns were studied as part of a randomized controlled trial among school-aged children from an ethnic minority group in Yunnan province, People's Republic of China. Children with a soil-transmitted helminth infection (N = 194) were randomly assigned to triple-dose albendazole or placebo and their infection status monitored over a 6-month period using the Kato-Katz and Baermann techniques. Baseline prevalence of Trichuris trichiura, Ascaris lumbricoides, hookworm, and Strongyloides stercoralis were 94.5%, 93.3%, 61.3%, and 3.1%, respectively, with more than half of the participants harboring triple-species infections. For the intervention group (N = 99), the 1-month post-treatment cure rates were 96.7%, 91.5%, and 19.6% for hookworm, A. lumbricoides, and T. trichiura, respectively. Egg reduction rates were above 88% for all three species. Rapid re-infection with A. lumbricoides was observed: the prevalence 4 and 6 months post-treatment was 75.8% and 83.8%, respectively. Re-infection with hookworm and T. trichiura was considerably slower.

“…5 Although it was not possible to obviate the impact of participants' sociodemographic characteristics on the difference of infection spectrum between two studies, both findings indicated that infection rates of intestinal parasites in humans were lower in central China than in southern and western China, where infection rates were 40%. 7,8 Previous studies focusing only on the effect of helminth infections on TB suggested that helminth infections may be the risk factor for active PTB in addition to HIV infection, 18 as well as have a negative influence on human immunity against TB. 9,19 However, a review showed that PTB and parasitic diseases were shown to be risk factors for each other.…”

“…The infection rate for Blastocystis hominis was approximately 22% in rural central China, 5,6 and the overall prevalence of soil-transmitted helminths was approximately 40-68% in rural southwestern and western China. 7,8 However, there is a paucity of epidemiologic studies on co-infection with TB and intestinal parasites in China.…”

Abstract. Epidemiologic studies of co-infection with tuberculosis (TB) and intestinal parasites in humans have not been extensively investigated in China. A cross-section study was conducted in a rural county of Henan Province, China. Pulmonary TB (PTB) case-patients receiving treatment for infection with Mycobacterium tuberculosis and healthy controls matched for geographic area, age, and sex were surveyed by using questionnaires. Fecal and blood specimens were collected for detection of intestinal parasites, routine blood examination, and infection with human immunodeficiency virus. The chi-square test was used for univariate analysis and multivariate logistic regression models were used to adjust for potential confounding factors. A total of 369 persons with PTB and 366 healthy controls were included; all participants were negative for human immunodeficiency virus. The overall prevalence of intestinal parasites in persons with PTB was 14.9%, including intestinal protozoa (7.9%) and helminthes (7.6%). The infection spectrum of intestinal parasites was Entamoeba spp. (1.4%), Blastocystis hominis (6.2%), Trichomonas hominis (0.3%), Clonorchis sinensis (0.3%), Ascaris lumbricoides (0.5%), Trichuris trichiura (2.2%), and hookworm (4.6%). The prevalence of intestinal parasites showed no significant difference between persons with PTB and healthy controls after adjusting for potential confounding factors. There was no factor that affected infection rates for intestinal parasites between the two groups. Infection with intestinal parasites of persons with PTB was associated with female sex (adjusted odds ratio [AOR] = 2.05, 95% confidence interval [CI] = 1.01-4.17), body mass index 19 (AOR = 3.02, 95% CI = 1.47-6.20), and anemia (AOR = 2.43, 95% CI = 1.17-5.03). Infection of healthy controls was only associated with an annual labor time in farmlands 2 months (AOR = 4.50, 95% CI = 2.03-10.00). In addition, there was no significant trend between rates of infection with intestinal parasites and duration of receiving treatment for infection with M. tuberculosis in persons with PTB. The prevalence of intestinal parasites was not higher in persons with PTB, and there was no evidence that PTB increased susceptibility to intestinal parasites in this study. However, for patients with PTB, women and patients with comorbidities were more likely to be infected with intestinal parasites.

“…Soil that contaminated by worm eggs/stool is the main source of transmission. In addition, the high resistance of worm eggs, humidity and tropical temperatures strongly support the occurrence of continuous infection (Mofid et al, 2011;Kattula et al, 2014).…”

Soil Transmitted Helminth (STH) infection is the third ranks of the top 10 common infectious diseases in the world, with an incidence rate about 1.4 billion per year. The incidence of STH in Indonesia is still quite high. Amount 60-80% of STH infection is occurs in primary school students, while 40%-60% infection for all ages. The purpose of this study was to determine factors related to STH infection in primary school children at Moyudan Primary School in Sleman Regency. This research conducted using an analytic observational with the cross-sectional design. The population in this study was all students of grade I, II, and III in Moyudan Primary School. This study took 60 respondents as samples with total sampling technique. Data were analyzed using chi-square test. The results showed that the habit of hand washing before eating (p= 0.010; RP= 3.850), the habit of hand washing after defecating(p= 0.007; RP= 4.571), nail hygiene (p= 0.179; RP= 2.138), the habit of wearing footwear (sig= 0.008; RP= 3.714), and defecation habits (p= 0.004; RP= 4.000). It can be concluded that there STH infection was associated with hand washing before eating, hand washing after defecating, the habit of wearing footwear and defecation habits on Moyudan Primary School the students. It was not associated with nail hygiene.
