In February, 2022, WHO published new guidelines with six recommendations to update the global public health strategy against schistosomiasis, including expansion of preventive chemotherapy eligibility from the predominant group of school-age...d children to all age groups (2 years and older), lowering the prevalence threshold for annual preventive chemotherapy, and increasing the frequency of treatment. This Review, written by the 2018-2022 Schistosomiasis Guidelines Development Group and its international partners, presents a summary of the new WHO guideline recommendations for schistosomiasis along with their historical context, supporting evidence, implications for public health implementation, and future research needs.

Lesson on schistosomiasis (bilharziasis): Causes, Symptoms and Treatment. Schistosomiasis is caused by parasitic blood flukes from the genus schistosoma. Schistosoma cercariae penetrate human skin and enter the bloodstream of the infected individual, where the parasites enter the portal vein. Schist...osoma parasites also enter the mesenteric and bladder circulations, where they release eggs. Symptoms of schistosomiasis are related to the location of the parasites, the parasite burden and the amount of eggs produced. Systems affected in schistosomiasis include the hepatic, splenic, genitourinary, pulmonary, and nervous systems.

In 2014, an estimated 40 million women of reproductive age were infected with Schistosoma haematobium, S. japonicum and/or S. mansoni. In both 2003 and 2006, the World Health Organization (WHO) recommended that all schistosome-infected pregnant and breastfeeding women be offered treatment, with praz...iquantel, either individually or during treatment campaigns. In 2006, WHO also stated the need for randomized controlled trials to assess the safety and efficacy of such treatment. Some countries have yet to follow the recommendation on treatment and many programme managers and pregnant women in other countries remain reluctant to follow the recommended approach.

AWMF guideline, seit 5 Jahren nicht mehr aktualisiert, wird gerade überarbeitet
The estimated share of people at risk of schistosomiasis who require preventive chemotherapy.
PLOS Glob Public Health 4(12): e0004035. https://doi. org/10.1371/journal.pgph.0004035.
A new formulation of praziquantel, arpraziquantel (arPZQ), has been developed for preschool-
aged children (PSAC) to fill the treatment gap for this age group in schistosomiasis control and
elimination program...s. There is now a priority to ensure that the drug reaches all at-risk PSAC
in endemic areas, including hard-to-reach areas and populations. This study aimed to deter-
mine schistosomiasis treatment-related contextual factors among fishermen and island popu-
lations in Homa Bay County, Kenya, and to identify a suitable platform to deliver arPZQ.

Urogenital schistosomiasis is a common neglected tropical disease in many rural communities in African countries, with patches of infection in the Eastern Mediterranean Region. Globally, an estimated 239 million people are currently infected, with burden estimated at more than 3.5 million disability...-adjusted life years (DALYs). In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

A manual for impact assessments. The SCH Practical and Precision Assessment (SPPA) strategy is an evidence-based approach for conducting impact assessments for SCH. The SPPA was identified by programme managers and SCH experts from the African region as a feasible and sufficiently accurate approach ...after reviewing and discussing the results of a multi-country study. This manual describes the resulting Practical and Precision Assessments approach and includes a discussion of the underlying concepts, factors to consider when determining what approach is appropriate, and how to interpret the collected data. The manual also includes annexes with standard operating procedures for conducting the stool and urine analyses.

Schistosomiasis is one of the 17 ‘neglected tropical diseases’ as classified by the World Health Organization.
In order to better understand attitudes and practices surrounding schistosomiasis, Malaria Consortium carried out a survey in Nampula province, Mozambique, where the organisation is i...mplementing a community engagement intervention with a
focus on this disease. Findings suggest a need for greater efforts to improve knowledge of schistosomiasis in affected communities
in order to increase uptake of mass drug administration and ensure that communities take appropriate measures to prevent infection.

The Community Dialogue Approach is a promising social and behaviour change intervention, which has shown potential for improving health seeking behaviour. To test if this approach can strengthen prevention and control of schistosomiasis at community level, Malaria Consortium implemented a Community ...Dialogue intervention in four districts of Nampula province, Mozambique, between August 2014 and September 2015.

Schistosomiasis and soil-transmitted helminths (STH) infections are major public health problems. We aimed to study the 6-mo impact of mass drug administration with praziquantel and albendazole on urinary schistosomiasis and STH.We examined children (aged 2–15 y) from one hamlet, who provided urin...e and faeces samples at baseline (n=197), 1 mo (n=102) and 6 mo (n=92); 67 completed the protocol.At baseline, 47/67 (70.1%) children presented Schistosoma haematobium (75.8% in the baseline total sample) and 12/67 (17.9%) with STH (30.5% in the initial sample, p=0.010). Among the children, 47.3% had heavy Schistosoma haematobium infection. The most frequent STH was Trichuris trichiura in 9.0%. We also found Hymenolepis nana (13.2%) and Plasmodium falciparum (9.1%) infections and anaemia (82.1%). One mo after chemotherapy there was a significant (p=0.013) reduction of Schistosoma haematobium prevalence (23.5%) and a high egg reduction rate (86.9%). Considering the sample of 67 children, the mean egg concentration was 498 at baseline, 65 at 1 mo and 252 at 6 mo (p<0.05). We also observed a reduction in STH infections, 50% in Ascaris lumbricoides, 33.3% in T. trichiura and 50% in hookworms. At 6 mo, the prevalence of Schistosoma haematobium (76.1%) was similar to the baseline and the STH reduction was not significant.Longitudinal studies have reported many losses in these settings, but we were able to show that mass drug administration for control of schistosomiasis and STH present low effectiveness, that reinfections occur rapidly and that stand alone anthelmintic therapy is not a sustainable choice.

Plants have a lot of potential and will continue to contribute feasible, effective medicines and/or pesticides; more research is warranted to fully explore their future applications

The control and elimination of schistosomiasis have over the last two decades involved several strategies, with the current strategy by the World Health Organization (WHO) focusing mainly on treatment with praziquantel during mass drug administration (MDA). However, th...e disease context is complex with an interplay of social, economic, political, and cultural factors that may affect achieving the goals of the Neglected Tropical Disease (NTD) 2021-2030 Roadmap. There is a need to revisit the current top-down and reactive approach to schistosomiasis control among sub-Saharan African countries and advocate for a dynamic and diversified approach.
