Bayesian spatial analysis of a national urinary schistosomiasis questionnaire to assist geographic targeting of schistosomiasis control in Tanzania, East Africa
Spatial modelling was applied to self-reported schistosomiasis data from over 2.5 million school students from 12,399 schools in all regions of mainland Tanzania. The aims were to derive statistically robust prevalence estimates in small geographical units (wards), to identify spatial clusters of high and low prevalence and to quantify uncertainty surrounding prevalence estimates. The objective...
متن کاملBayesian spatial analysis and disease mapping: tools to enhance planning and implementation of a schistosomiasis control programme in Tanzania.
OBJECTIVE To predict the spatial distributions of Schistosoma haematobium and S. mansoni infections to assist planning the implementation of mass distribution of praziquantel as part of an on-going national control programme in Tanzania. METHODS Bayesian geostatistical models were developed using parasitological data from 143 schools. RESULTS In the S. haematobium models, although land surf...
متن کاملImpact of school health programme on urinary schistosomiasis control in schoolchildren in Kilosa, Tanzania.
Urinary schistosomiasis is more prevalent in schoolaged children than in adults (Hussein et al., 1996). Thus interventions aimed at school-aged children focusing on delivery through schools are strongly encouraged (WHO, 1993). School-based programmes provide an infrastructure for delivering treatment against geohelminths and schistosomiasis (PCD, 1999). Such programmes have been shown to improv...
متن کاملAttempts to Achieve Millennium Development Goals in a Rural Area of Rio de Janeiro: Deworming and Control of Schistosomiasis
Introduction: According to the World Health Organization (WHO), helminth control could contribute to achieving 7 Millennium Development Goals (MDGs). The present study evaluated the impact of deworming on the infection rate of schistosomiasis in Sumidouro, Brazil and the consequences for the MDGs. Methods: The whole population of this area was invited to ...
متن کاملHuman Schistosomiasis in the Middle East and North Africa Region
Human schistosomiasis is one of the most common Neglected Tropical Diseases (NTDs); it is an intravascular parasite caused by the trematode blood fluke (Schistosoma). Most human infections are caused by S. haematobium, S. mansoni, and S. japonicum. An estimated total of 237 people are infected worldwide, and 732 million people are at risk of being infected. In the Middle East and North Africa (...
