Temperature Data from Satellite Imagery and the Distribution of Schistosomiasis in Egypt

Contributions on human fascioliasis and its snail intermediate host in Nile Delta, Egypt

“…Infection rate has no sex or age limits but it depends mainly on the feeding habits of the people and their general hygienic measures. The high percentage of human infection in Motobus and Sedi Salem agreed with the fact published by Malone [7] where these two sites had low diurnal temperature difference (difference in temperature between day and night) which means that there is more moisture in the area; the condition which helped the continuous persistence of the IMH snail. This rate of infection will be more investigated via another running work that will be published by the same authors in the near future depending on serological and immunological techniques.…”

“…This thermal difference values reflect regional hydrologic conditions that can be used as a predictor of environmental risk assessment which depends for some extent on the persistence of the trematoda snail's intermediate hosts [7]. According to this satellite temperature and hydrological data, Kafr El-Sheik governorate has 3 main zones as wet (dT from 12-14 ºC), moist (dT from 14-16C) and dry (dT from 16-20C).The study sites were selected to represent these 3 different zones, as Motobus and Sedi Salem represent the wet zone, Shenno and Abioka represent the moist zone while El-Halafy and El-Kafr El-Sharky represent the dry zone.…”

“…In the present study field and laboratory work aimed at better defining of Fasciola as a zoonotic problem with special interest to determine IMH snail responsible for spreading of infection to human. Kafr El-Sheikh governorate was selected as a study area, as it is considered to be an ideal habitat for different snails in the Nile Delta [7]. These field efforts aimed at determining the status of Fasciola infection in human in 6 selected regions in Kafr El-Sheik governorate.…”

Mapping and modelling neglected tropical diseases and poverty in Latin America and the Caribbean

“…It discussed early healthrelated applications based on GIS and remote sensing, including malaria and schistosomiasis in East Africa and Egypt in the mid-1990s (Beck et al, 1994;Malone et al, 1994;Kitron et al, 1996). In the Americas, the Oswaldo Cruz Foundation (FIOCRUZ), the U.…”

The Estrada Real project and endemic diseases: the case of schistosomiasis, geoprocessing and tourism

“…Brown (1994) and Appleton (1978) documented the climate and environmental variables that influenced the distribution of schistosomiasis. GIS was used in a larger scale schistosomiasis study in Asia (Cross et al 1996, Seto et al 2002, Yang et al 2005, Zhang et al 2008) and in several African countries, including Ethiopia , Egypt (Abdel-Rahman et al 2001, Malone et al 1994, Uganda (Kabatereine et al 2004), Tanzania (Brooker et al 2001) and Chad (Beasley et al 2002, Brooker 2002). In the state of Bahia, Brazil, Bavia et al (2001) conducted one of the first studies that attempted to correlate disease distribution with environmental variables.…”
