Recent systematic reviews and meta-analysis of the impact of chemical-based mollusciciding (King et al., 2015, Sokolow et al., 2016) have concluded that regular mollusciciding is likely to contribute significantly towards elimination of schistosomiasis in high-risk areas. The WHO roadmap’s new foc...us on “transmission control, wherever possible” (WHO, 2012a) reinforces the need to promote intermediate-host snail control to prevent schistosomiasis transmission.
This operational manual is intended to facilitate the reintroduction of practices and protocols for use of molluscicides in the field in schistosomiasis control programmes. It is complemented by guidelines on the laboratory and field testing of the efficacy of molluscicides for schistosomiasis control (WHO, 2017 [in preparation]).

Plos Neglected Tropical Diseases 8(11): e3229 (20 November 2014)
Despite pandemic-related disruptions, a total of 76.9 million people received treatment for schistosomiasis in 2020, representing a global coverage of 31.9%, compared with 105 million treated in 2019 (coverage of 44.8%).
The latest data published by the World Health Organization (WHO) show that 2...8.6 million fewer people were treated for schistosomiasis (bilharzia) in 2020 than in 2019. This 27% drop in the number of treatments delivered is largely due to the implementation of COVID-19 measures, including school closures.

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.

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, the disease context is complex wi...th 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.

Schistosomiasis is a chronic disease linked to poverty and is widely endemic, particularly in sub-Saharan Africa. For decades, the World Health Organization has called for a larger role of the primary health care system in schistosomiasis control, and its integration within the routine activities of... primary health care facilities. Here, we reviewed existing studies on the integration of schistosomiasis control measures within the primary health care system, more precisely at the health centre, and we analysed their outcomes.

With some 134,073,166 people living in endemic communities at risk of infection, Nigeria is the most endemic country in Africa and requires preventive chemotherapy (PC) for a total of 26.3 million persons. The National Schistosomiasis Elimination Programme (NSCHEP), with the support of international... partners, has been implementing PC in Nigeria since 2009 and most recently will need to revise its current strategy (Additional file 1). For example, the new World Health Organization (WHO) guideline has six key recommendations that will dramatically change the implementation of schistosomiasis elimination in endemic countries [3]. However, its impact and programmatic implications will vary from country to country, hence the need for a country-specific analysis. This article discusses these recommendations with specific reference to the challenges and opportunities in Nigeria. We summarise the key pointers in Additional file 1: Box 1 against the six recommendations of the WHO 2022 guideline.

The control of schistosomiasis was a high priority in China soon after the founding of the People’s Republic of China in 1949, and schistosomiasis japonica was largely brought under control through 7 decades of effort. However, great challenges still exist to completely eliminate schistosomiasis f...rom the country by 2030 due to climate change, natural disasters, socioeconomic development, environmental protection, etc. The progress of the national schistosomiasis control program and the experience
accumulated over past several decades in China is reviewed in this article, and solutions to achieve the elimination of schistosomiasis through a One Health
approach are explored, which addresses complex health issues from a holistic perspective of human-animal-environment interaction.

Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms. Although the worms that cause schistosomiasis are not found in the United States, people are infected worldwide. In terms of impact this disease is second only to malaria as the most devastating parasitic disease. Sc...histosomiasis is considered one of the neglected tropical diseases (NTDs).

Recently, schistosomiasis is reported also from Myanmar, viz. Rakhine State, Southern Shan State (near Lake Inle) and Bago Region. Between October 2016 and 30 June 2018, for instance, 302 cases have been diagnosed at Sittwe General Hospital.
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.

Clin Microbiol Infect 2010; 16: 225–231 Abstract In non-endemic countries, acute (invasive) schistosomiasis (AS) is typically seen in non-immune travellers, whereas chronic schistosomiasis is more frequently diagnosed in immigrants. Travellers with AS initially present with non-specific signs such... as fever, cough, headache, and urticaria. Life-threatening cardiac and neurological complications may occur. The positive diagnosis of AS relies on seroconversion, which appears together with hypereosinophilia approximately 3 weeks after the onset of symptoms. When prescribed during AS, praziquantel usually does not prevent the chronic phase of the disease and is associated with exacerbation of signs and symptoms in approximately 50% of cases. According to the published literature, corticosteroids may be recommended alone or in association with praziquantel. When associated with corticosteroids, pharmacokinetic interactions may impair the efficacy of praziquantel. We suggest that corticosteroids should be restricted to use in patients with systemic complications of AS, whereas praziquantel should be initiated only when ova are detected in either stools or urine, depending on the culprit species.

The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.
