The study by Aguiar-Santos et al.1 indicates that, in spite of several years of interventions aimed at eliminating lymphatic filariasis (LF) from Pernambuco, its transmission is still occurring at sustained levels (13.8% mf prevalence); the study also shows that soil-transmitted helminthiasis (STH) is still significantly prevalent among surveyed children (46.5% or 74/159). High prevalence of ly...

We explored the practicality of integrating surveillance for soil-transmitted helminthiasis (STH, assessed by Kato-Katz) with transmission assessment surveys for lymphatic filariasis (LF) in two evaluation units (EUs) in Gampaha district, Sri Lanka (population 2.3 million). The surveys were performed 6 years after five annual rounds of mass drug administration with diethylcarbamazine and albend...

Pyrantel has been demonstrated (Bumbalo et al., 1969; Desowitz et al., 1970; Hsieh, 1971) to be effective for treatment of Ascaris, hookworm and Enterobuis. Oxantel has been shown (Zaman and Sabapaty, 1975; Garcia, 1976; Lee et al., 1976; Rim et al., 1976) to be effective against Trichuriasis. A combined Oxantel-pyrantel salts has been shown (Rim et al., 1975; Lim, 1978; Dissanaike, 1978; Cabre...

Substantial investment has been made into the once "neglected" tropical disease, soil-transmitted helminthiasis, and into control programs that operate within a framework of mapping baseline disease distribution, measuring the effectiveness of applied interventions, establishing when to cease drug administration, and for posttreatment evaluations. However, critical to each of these stages is th...

Pre-school age children account for 10%-20% of the 2 billion people worldwide who are infected with soil-transmitted helminths (STHs): Ascaris lumbricoides (roundworm), Trichuris trichiura (whipworm), and Ancylostoma duodenale/Necator americanus (hookworms). Through a systematic review of the published literature and using information collated at World Health Organization headquarters, this pap...

Only few studies in rural China have explored the epidemiology of intestinal helminth infections and identified risk factors for transmission. The study was carried out in Simao and Mengla counties, where single fecal samples were collected from 317 school-aged children and from 94 inhabitants of a single village. Fecal specimens were examined with the Kato-Katz thick smear method and examined ...

This study aimed to assess the current situation of STH in pregnant women, explore factors associated with STH and evaluate the effects of its treatment. A cohort study was conducted in four southernmost provinces. All pregnant women who presented at their first prenatal care visit at participating hospitals were interviewed by trained health care providers and their stool specimens were examin...

BACKGROUND Schistosomiasis and soil-transmitted helminthiasis (STH) are widely distributed in Cameroon. Although mass drug administration (MDA) of mebendazole is implemented nationwide, treatment with praziquantel was so far limited to the three northern regions and few health districts in the southern part of Cameroon, based on previous mapping conducted 25 years ago. To update the disease dis...

Even though Rwanda lies within a region that has a high prevalence of schistosomiasis and soil-transmitted helminth (STH) infections, epidemiological information regarding these infections in the country remains scarce. The present review attempts to compile the available data on schistosomiasis and STHs, from 1940 to 2014, to provide an insight on the epidemiological profile of these infection...

epidemiological features of soil transmitted helminthes were studied in six villages in isfahan area. the mean overall prevalence of ascariasis and trichostrongyliasis were 91.5% and 70.9% respectively with higher infection rate among females. mean prevalence of trichuris and hymenolepis nana were 73.8% and 5.4% respectively. prevalences of ascaris and trichuris did not fluctuate very much in v...
