his first edition describes the standard operating procedures for health products for NTDs amenable to preventive chemotherapy and the medicines donated to treat them. These include albendazole for lymphatic filariasis and soil-transmitted helminthiases; azithromycin for trachoma and yaws; diethylca...rbamazine citrate for lymphatic filariasis; ivermectin for onchocerciasis and lymphatic filariasis; mebendazole for soil-transmitted helminthiases; praziquantel for schistosomiasis; and triclabendazole for foodborne trematodiases. Standard operating procedures for diseases amenable to case management will be covered in subsequent editions, including the application process for requesting medicines (Chapter 1). In the meantime, the procedures described in the rest of the document apply for both case management and preventive chemotherapy NTD health products.

Schistosomiasis, also known as Bilharzia, is an infection caused by a parasitic worm that lives in fresh water in subtropical and tropical regions. Schistosomiasis is second only to malaria as the most devastating parasitic disease. The parasites that cause schistosomiasis live in certain types of f...reshwater snails. The infectious form, known as cercariae, emerge from the snail and then contaminate the water. People become infected when their skin comes into contact with the contaminated freshwater. Most human infections are caused by Schistosoma mansoni, Schistosoma haematobium, or Schistosoma japonicum.

This document provides up-to-date guidance on laboratory studies as well as smallscale (semi-field) and large-scale field trials to assess the efficacy and determine field
application rates of new molluscicide products for control of schistosomiasis.
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.

Human schistosomiasis otherwise called bilharzia, is a fresh- water snail transmitted intravascular debilitating disease resulting from infection by the parasitic dimorphic Schistosoma trematode worms, which lives in the bloodstream of humans. The World Health Organization (WHO) regards the disease ...as a neglected tropical disease, with an estimated 732 million persons being vulnerable to infection worldwide in renowned transmission areas. Steinmann and co-workers documented that over 200 million individuals from Africa, Asia, and South America are infected with this disease. The WHO further estimated that schistosome infections and geohelminths accounts for over 40% of the world tropical disease burden with the exclusion of malaria. Humans get infected with this disease when they make contact with water contaminated with the skin-penetrating cercariae. Prevalence of schistosomiasis, at present, is still high in sub-Saharan Africa. In 2008, 17.5 million people were treated globally for schistosomiasis, 11.7 million of those from sub-Saharan Africa only. Approximately 120 million individuals in sub-Saharan Africa have schistosomiasis-related symptoms while about 20 million undergo hardship as a result of chronic presentations of the disease.

Theodor Bilharz, a German professor of anatomy and chief of surgery at the Kasr El Ani Hospital of Cairo from 1850, first identified an infective organism, Distomum hematobium in 1851, which was renamed Schistosoma haematobium in 1858. It arose from a cestode worm, Hymenoleptis nana, lying in the sm...all colon of an Egyptian patient. He also discovered a trematode worm at the same time from an autopsy, thought to be the cause of urinary Schistosomiasis. Bilharz died from typhoid fever in 1862 at the age of 37. The Theodor Bilharz Research Institute in Giza, Egypt, stands as a tribute to him today. F. Milton published the first recorded peer-reviewed article report on Schistosomiasis in 1914.

Schistosomiasis, commonly known as bilharzia, is an acute and chronic tropical disease caused by trematodes of the genus Schistosoma. The schistosome parasite is transmitted through a snail intermediate host with the human being the definitive host. Worldwide, schistosomiasis continues to cause a pu...blic health problem with 779 million people exposed to the infection. The disease is present in 78 countries and endemic in 52 of those countries where an estimated 90% of people need treatment. Schistosomiasis has been successfully controlled in many countries but its burden remains high in Africa, particularly in sub-Saharan countries.

Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms that require two hosts: humans and certain species of snails. There are two forms of the disease, namely, intestinal schistosomiasis, caused by Schistosoma mansoni and S. japonicum, and urogenital schistosomiasis, cause...d by S. haematobium. There are less common schistosome species in some parts of the world, e.g. S. mekongi and S. intercalatum. Schistosomiasis ranks second only to malaria as the most common parasitic disease worldwide.

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.

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]).
