“…Two years after in 2002 prevalence were 43.4 and 90.8 %, respectively (Poda et al 2004). Zongo et al (2012) indicated a global prevalence of 3 % for S. haematobium among school aged children in the Sourou Valley and within a particular context of mass drug administration with praziquantel. These authors have also observed that in general in Burkina Faso, prevalence of S. haematobium is decreasing while that for S. mansoni is increasing.…”

“…The first method was used in this study, consisting in tracking contact activities namely swimming and bathing. The link to the risk of schistosomiasis transmission in the context of this study was limited to the contact with the Sourou River standing as an excellent habitat both for Bulinus truncatus, the snail intermediate hosts for S. haematobium, and Biomphalaria pfeifferi, snail intermediate host for S. mansoni (Poda et al 2004;Dianou et al 2004;Poda et al 2006;Zongo et al 2012). Since the schistosomiasis transmission route is the contact with water, any contact with the river is deemed to be risky.…”

“…Previous epidemiologic and biologist studies showed that human schistosomiasis is widely spread in Burkina Faso (Poda et al 2004;Koukounari et al 2007;Clements et al 2008;Koukounari et al 2011;Zongo et al 2012). Snails intermediate hosts collected and identified in the Sourou Valley were: Biomphalaria pfeifferi for the intestinal schistosomiasis (S. mansoni) and Bulinus truncatus and B. senegalensis for the urinary schistosomiasis (S. haematobium) (Dianou et al 2004;Poda et al 2004;Zongo et al 2012). The levels of prevalence in Toma-Île village were 51.9 % for the urinary schistosomiasis and 50.6 % for the intestinal schistosomiasis among school aged children.…”

Climate and water contacts are among the most important risk factors of human schistosomiasis transmission. This study aimed to determine-through direct field observations-the influence of air temperature on the frequencies of childreńs water contacts with respect to human schistosomiasis transmission risk in the Sourou Valley, located in the North-western part of Burkina Faso. The objectives of the study were: (i) to study the air temperature at which children have the sensation of heat and start looking for water as a means for natural cooling; and (ii) to study whether high frequencies of swimming or bathing may lead to a higher risks of schistosomiasis transmission. To do so, swimming or bathing were observed during two different periods: a cold one from 3rd January to 2nd February 2011 and a hot one from 3rd April to 3rd May 2011 in Toma-Île, a village totally surrounded by water. The results showed that daily mean air temperatures never exceeded 30°C during the coldest period, while they were above this value during the hottest period. In total, swimming activities were observed 11/31 days during the coldest period and 31/31 during the hottest period. Bathing of children below the age of 5 years occurred on 55/62 days. 25°C was the day mean air temperature from which children felt hot and began playing in water. The hourly occurrence of swimming and bathing showed peaks at 2 PM. This coincides with the diurnal maximum of infective cercariae present in the same water. Thus, in order to freshen up during hot periods of the day, children used to look for freshwater and thus expose themselves to a high schistosomiasis transmission risk.

The prevalence and intensity of the infection caused by schistosomiasis and geohelmintiasis were studied in relation to irrigated rice cultivation in Côte d'Ivoire. In a cross-sectional study conducted on schistosomiasis in Niakaramandougou, in the savannah (North) area of Côte d'Ivoire, from April to September 2001, the potential importance of soil-transmitted helminth infections was assessed. Villages were classified according to the surrounding inland valleys into two agro-ecosystems: (R2) full or partial water control allowing two rice cycles per year and (R0), the absence of rice growing. Urine and stool samples were collected from children in two villages in the savannah zone. Three hundred and fifty-three (353) children aged 4 to 15 years were examined, of whom 220 were from Kafiné village (R2) and 133 from Pékaha village (R0). The prevalence of Schistosoma haematobium was 10%, and 2.3% in R2 and R0 respectively. S. mansoni prevalence was 29.1% in R2 and 31.6% in R0. Ascariasis lumbricoides (12.3%) and Trichuris trichuira were the only species present in the two agro-ecosystems. Prevalences of S. haematobium adjusted for the effects on the villages were significantly different in the two agro-ecosystems. In savannah rice growing villages, negative binomial regression on the intensity of the infection of S. haematobium showed significant positive relations with the surface of rice cultivated inland valleys, whereas uncultivated inland valleys showed no significant relation. However, S. mansoni infection intensity showed significant negative relations with infection intensity of each agro-ecosystem.

Intestinal schistosomiasis or intestinal bilharzia, mainly caused by Schistosoma mansoni, is one of the most common parasitic diseases in the world, and a neglected tropical disease (NTD). It ranks first among water-borne diseases and is the 2nd most endemic parasitic disease after malaria and according to the World Health Organization (WHO), schistosomiasis is transmitted in more than 78 countries and territories in tropical and subtropical regions, and more than 250 million people are infected, mainly in Africa. Kato Katz (KK) remains the standard technique for diagnosing this disease. A promising new approach, loop-mediated isothermal amplification (LAMP), may be needed in developing countries such as Burkina Faso. Thus, the aim of this study was to compare the LAMP technique and the Kato-Katz technique in the diagnosis of Schistosoma mansoni in Burkina Faso. 52 stool samples were collected from patients in the town of Bobo Dioulasso and examined using the KK technique, which corresponds to microscopy and the LAMP technique, to assess the sensitivity and specificity of this molecular technique. The results showed a prevalence of intestinal schistosomiasis of 8% in the study, and the Kappa coefficient obtained between the 2 techniques was 0.99, roughly equal to 1. The sensitivity and specificity of the LAMP molecular test was 100%.
