International Journal of Infectious Diseases Volume 54, January 2017, A new global strategy for the elimination of schistosomiasis. Numerous studies have claimed that ‘preventive chemotherapy’ utilising 40 mg/kg of PZQ given annually can significantly reduce the prevalence and intensity of infection, and control morbidity in the long term.6, 7 However, PZQ is not 100% curative in killing adult worms, cannot kill migrating schistosomulae or the early stages of the disease, and does not prevent reinfection.8, 9 It has been stated that MDA may reduce population immunity in the long term and if stopped can lead to large rebounds in egg counts.10, 11 Moreover, multiple rounds of MDA among school children have resulted in a reduced efficacy of PZQ which poses a threat to global MDA programs.12 Parasitological cure depends on the treatment dose.
Inadequate treatment coverage is a serious obstacle for MDA implementation. Figure 1 Percentage of global target population reached with ‘preventive chemotherapy’ for schistosomiasis control.

ONE HEALTH 28/02/17 Integrated preventive chemotherapy and WASH for intensified schistosomiasis and soil transmitted helminthiasis control. Preventive chemotherapy (deworming) has a pivotal role in control of certain neglected tropical diseases (NTDs) such as schistosomiasis and soil-transmitted helminthiasis (STH), as a short-term, rapid impact intervention.
As these two diseases are strongly associated with poverty, people frequently get re-infected after treatment from their local environment since they have insufficient access to safe water sources or adequate sanitation and hygiene. To have a more enduring health impact, preventive chemotherapy needs to be augmented with other interventions such as water, sanitation and hygiene (WASH) approaches.

THE LANCET 20/06/14 Prehistoric schistosomiasis parasite found in the Middle East. See all References3 Human skeletal remains dated 6500–6000 BP were excavated in this location, and sediment collected from the pelvic area of 26 individuals, where the intestines and bladder were during life.
Control samples from the head and feet were also taken, where parasites of abdominal organs would not be expected. The sediment underwent disaggregation, microsieving through mesh of 300, 160, and 20 μm, and light microscopy. One individual had evidence for infection with a terminal spined schistosome.

Infectious Diseases of Poverty 2015, 4:4 Urban schistosomiasis and associated determinant factors among school children in Bamako, Mali, West Africa. Study area The study was conducted in Bamako (12°39’ N latitude and 8°0’ W longitude), the capital city of Mali (see Figure 1).
The surface area of the city is 1420 km2. The town looks like a big basin, surrounded in part by hills, with the Niger River and its tributaries flowing across. The town belongs to the North-Soudanian climatic zone with two major seasons: the wet season from November to May with its beginning and end marked by torrential rains and thunderstorms, and the dry season from April to October. The mean annual rainfall is about 1,400 mm, which occurs mainly during the period from July to September. Figure 1. Bamako was founded at the end of the 16th century. Study design and sampling techniques The survey was conducted in twenty-nine (29) blocks, each 200 m × 200 m, in Bamako.
One school inside or nearest to each of the 29 blocks was chosen for parasitological investigations in order to study the distribution of schistosomes in Bamako. GLOBAL NETWORK 08/06/15 Government of Nigeria Releases New Data on the Prevalence of Schistosomiasis and Intestinal Worms. On Thursday June 4, Nigeria’s Federal Ministry of Health released, for the first time, comprehensive data on the national distribution of two major neglected tropical diseases (NTDs) — schistosomiasis and intestinal worms.
This new information, gathered by the government of Nigeria and a network of partners, found that across 19 states and the Federal Capital Territory (FCT) approximately 24 million Nigerians were at risk for schistosomiasis and 21 million were at risk for intestinal worms. Children between the ages of 5 – 10 had the highest prevalence of infection. The results also showed that men were more likely than females to have one of the diseases. Nigeria is said to have the highest burden of NTDs in sub-Saharan Africa. While the government and NGO partners have already taken several steps to address the burden of disease, comprehensive epidemiological mapping had not been available until recently. ECDC 22/05/14 Local transmission of Schistosoma in Corsica, France: Risk limited to residents and people visiting the area, infection only through contact with freshwater.
As of 16 May 2014, eleven cases (six from France and five from Germany) of uro-genital schistosomiasis (Schistosoma haematobium) have been reported.
All cases were exposed to freshwater in a natural swimming area in southern Corsica (Cavu River). This is the first locally acquired infection of Schistosoma haematobium in France. The disease is known to be highly focal in its geographic distribution. Therefore, the risk of acquiring the infection exists only for residents and people who visit the affected area and engage in occupational or recreational activities in the river.

Schistosomiasis is a chronic parasitic disease, estimated to affect 237 million people worldwide. It is caused by infection with Schistosoma helminths, which spend part of their lifecycles in aquatic snails. The mortality, development and fecundity rates of the parasites and their intermediate host snails are very sensitive to water temperature. The distribution and prevalence of schistosome parasites are therefore likely to be affected by climate change, however the potential effects of this have been largely neglected.

CDC EID - AOUT 2013 - Au sommaire: Autochthonous Human Schistosomiasis, Malaysia. Suggested citation for this article To the Editor: In Malaysia, the only histologically diagnosed autochthonous cases of human schistosomiasis were reported in the 1970s, all in rural aborigine (Orang Asli) populations (1–3) (Technical Appendix Figure 1[PDF - 337 KB - 5 pages]( The fact that the infection had been found only among aborigines had led to the proposal of a distinct unknown schistosome with an animal reservoir causing sylvatic infections (2,3). Consequently, during the 1980s, Schistosoma malayensis n. sp. was described from intermediate snail (Robertsiella sp.) and final mammalian hosts (Rattus muelleri and R. tiomanicus ). S. malayensis is closely related to S. mekongi and differs genetically from the latter by ≈10%. Both species differ from S. japonicum by 25% (5), and adult and ova morphologies are similar (4). Few transmission sites for this new S. japonicum–complex schistosome species were identified in rural areas (4).

Abstract Background Appropriate diagnostics to monitor disease trends and assess the effectiveness and impact of interventions are essential for guiding treatment strategies at different thresholds of schistosomiasis transmission and for certifying elimination. Field validation of these assays is urgently needed before they can be adopted to support policy decisions of the national programme for control and elimination of schistosomiasis in P.R. China. We compared the efficacy and utility of different immunoassays in guiding control strategies and monitoring the endemic status of S. japonicum infections towards elimination. Methodology/Principal Findings Conclusions/Significance Studies suggest that ELISA_SZ could be used to guide selective chemotherapy in moderate or low endemic regions.
