| parasitic infections in black children in an endemic schistosomiasis area in natal. | urine and stool specimens from 856 school children aged from 7 to 20 years, and from 80 preschool children, were examined for schistosoma haematobium and intestinal helminths and protozoa. s. haematobium was present in 57% with a peak of 81% in 13-14-year-old children. peak intensity preceded peak incidence and egg loads gradually decreased with age. there was no clear-cut difference between boys and girls with regard to intestinal parasites, nor was there a close correlation between the inciden ... | 1977 | 191941 |
| targeted chemotherapy for parasite infestations in rural black preschool children. | to investigate whether targeted chemotherapy can reduce parasite prevalence rates in rural black preschool children. | 1995 | 8545746 |
| the distribution of common intestinal nematodes along an altitudinal transect in kwazulu-natal, south africa. | in order to study the effect of climate and topography on the distribution of common, intestinal nematodes in schoolchildren, changes in prevalence were investigated along an altitudinal transect from approximately 50 m above sea level (asl), near the coast, to approximately 1700 m asl, in the foothills of the drakensberg mountains, kwazulu-natal, south africa. these changes were related to several permutations of temperature, rainfall and evaporation, using univariate and multiple regression an ... | 1996 | 8762408 |
| the distribution of helminth infections along the coastal plain of kwazulu-natal province, south africa. | the results of a previous study indicated that, in the province of kwazulu-natal, south africa, necator americanus and strongyloides stercoralis were endemic to the coastal lowlands only. the prevalences of these helminths, as well as those of trichuris trichiura and ascaris lumbricoides, have now been investigated along a 1000-km-long transect through the coastal plain, at altitudes of < 300 m, from the mozambique border (26 degrees 57's) to the border with eastern cape province (30 degrees 53' ... | 1999 | 10715680 |
| a health and nutritional profile of rural school children in kwazulu-natal, south africa. | a community-based cross-sectional study was undertaken to measure anthropometric indices, micronutrient status and prevalence of parasite infections in 579 rural south african primary school children. eleven schools were selected randomly from a magisterial district in southern kwazulu-natal (kzn). in each school, all pupils aged between 8 and 10 years were selected. the following outcome measures were obtained: anthropometric--height for age, weight for age and body mass index; micronutrient st ... | 2001 | 11284248 |
| epidemiology of helminth infections: implications for parasite control programmes, a south african perspective. | to determine the epidemiology of helminthic infections and the efficacy of parasite treatment among rural south african primary school children in the province of kwazulu-natal. to assess the south african government's parasite control policy. | 2001 | 11796084 |
| geophagy and its association with geohelminth infection in rural schoolchildren from northern kwazulu-natal, south africa. | the social pattern of geophagy (soil-eating) and its possible role in the transmission of ascaris lumbricoides, trichuris trichiura and hookworm were investigated in a rural area of south africa between march 1998 and july 1999. schoolchildren (median age = 10.7 years; interquartile range 8.3-14.8 years) were examined for geohelminth infection at baseline and re-examined 3 and 29 weeks after treatment with albendazole. interviews were conducted with the pupils in order to find out about their so ... | 2002 | 12474473 |
| patterns of geohelminth infection, impact of albendazole treatment and re-infection after treatment in schoolchildren from rural kwazulu-natal/south-africa. | geohelminth infection is a major health problem of children from rural areas of developing countries. in an attempt to reduce this burden, the department of health of the province of kwazulu-natal (kzn) established in 1998 a programme for helminth control that aimed at regularly treating primary school children for schistosomiasis and intestinal helminths. this article describes the baseline situation and the effect of treatment on geohelminth infection in a rural part of the province. | 2004 | 15310401 |
| ecological covariates of ascaris lumbricoides infection in schoolchildren from rural kwazulu-natal, south africa. | to identify environmental factors that could serve to predict ascaris lumbricoides infection patterns and thus guide control efforts in the absence of epidemiological information; to assess whether a. lumbricoides infection is positively associated with the soil clay content. | 2005 | 15860087 |
| household-based prevalence of helminths and parasitic protozoa in rural kwazulu-natal, south africa, assessed from faecal vault sampling. | this study was undertaken to examine the family-based prevalence of environmentally persistent parasites in two rural communities of kwazulu-natal, south africa. samples were collected from 120 urine-diversion family toilets and screened for selected protozoa and helminths with immunomagnetic separation and the ammonium bicarbonate (ambic) protocol respectively. the parasites found were ascaris lumbricoides (59%), giardia intestinalis (54%), trichuris trichiura (48%), cryptosporidium spp. (21%) ... | 2010 | 20684963 |
