Trichuriasis, also known as whipworm infection, is an infection by the parasitic worm Trichuris trichiura (whipworm). If infection is only with a few worms, there are often no symptoms. In those who are infected with many worms, there may be abdominal pain, fatigue and diarrhea. The diarrhea sometimes contains blood. Infections in children may cause poor intellectual and physical development. Low red blood cell levels may occur due to loss of blood.
Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, is a disease caused by parasitic flatworms called schistosomes. The urinary tract or the intestines may be infected. Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. Those who have been infected for a long time may experience liver damage, kidney failure, infertility, or bladder cancer. In children, it may cause poor growth and learning difficulty.
Praziquantel (PZQ), sold under the brandname Biltricide among others, is a medication used to treat a number of types of parasitic worm infections in mammals, birds, amphibians, reptiles, and fish. In humans specifically, it is used to treat schistosomiasis, clonorchiasis, opisthorchiasis, tapeworm infections, cysticercosis, echinococcosis, paragonimiasis, fasciolopsiasis, and fasciolosis. It should not be used for worm infections of the eye. It is taken by mouth.
Helminthiasis, also known as worm infection, is any macroparasitic disease of humans and other animals in which a part of the body is infected with parasitic worms, known as helminths. There are numerous species of these parasites, which are broadly classified into tapeworms, flukes, and roundworms. They often live in the gastrointestinal tract of their hosts, but they may also burrow into other organs, where they induce physiological damage.
Oxamniquine, sold under the brand name Vansil among others, is a medication used to treat schistosomiasis due to Schistosoma mansoni. Praziquantel, however, is often the preferred treatment. It is given by mouth and used as a single dose.
Sir Roy Malcolm Anderson is a leading international authority on the epidemiology and control of infectious diseases. He is the author, with Robert May, of the most highly cited book in this field, entitled Infectious Diseases of Humans: Dynamics and Control. His early work was on the population ecology of infectious agents before focusing on the epidemiology and control of human infections. His published research includes studies of the major viral, bacterial and parasitic infections of humans, wildlife and livestock. This has included major studies on HIV, SARS, foot and mouth disease, bovine tuberculosis, bovine spongiform encephalopathy (BSE), influenza A, antibiotic resistant bacteria, the neglected tropical diseases and most recently COVID-19. Anderson is the author of over 650 peer-reviewed scientific articles with an h-index of 125.
Neglected tropical diseases (NTDs) are a diverse group of tropical infections that are common in low-income populations in developing regions of Africa, Asia, and the Americas. They are caused by a variety of pathogens, such as viruses, bacteria, protozoa, and parasitic worms (helminths). These diseases are contrasted with the "big three" infectious diseases, which generally receive greater treatment and research funding. In sub-Saharan Africa, the effect of neglected tropical diseases as a group is comparable to that of malaria and tuberculosis. NTD co-infection can also make HIV/AIDS and tuberculosis more deadly.
Opisthorchiasis is a parasitic disease caused by certain species of genus Opisthorchis. Chronic infection may lead to cholangiocarcinoma, a cancer of the bile ducts.
A Schistosomiasis vaccine is a vaccine against Schistosomiasis, a parasitic disease caused by several species of fluke of the genus Schistosoma. No effective vaccine for the disease exists yet. Schistosomiasis affects over 200 million people worldwide, mainly in rural agricultural and peri-urban areas of the third world, and approximately 10% suffer severe health complications from the infection. While chemotherapeutic drugs, such as praziquantel, oxamniquine and metrifonate both no longer on the market, are currently considered safe and effective for the treatment of schistosomiasis, reinfection occurs frequently following drug treatment, thus a vaccine is sought to provide long-term treatment. Additionally, experimental vaccination efforts have been successful in animal models of schistosomiasis.
Hookworm vaccine is a vaccine against hookworm. No effective vaccine for the disease in humans has yet been developed. Hookworms, parasitic nematodes transmitted in soil, infect approximately 700 million humans, particularly in tropical regions of the world where endemic hookworms include Ancylostoma duodenale and Necator americanus. Hookworms feed on blood and those infected with hookworms may develop chronic anaemia and malnutrition. Helminth infection can be effectively treated with benzimidazole drugs, and efforts led by the World Health Organization have focused on one to three yearly de-worming doses in schools because hookworm infections with the heaviest intensities are most common in school-age children. However, these drugs only eliminate existing adult parasites and re-infection can occur soon after treatment. School-based de-worming efforts do not treat adults or pre-school children and concerns exist about drug resistance developing in hookworms against the commonly used treatments, thus a vaccine against hookworm disease is sought to provide more permanent resistance to infection.
Malaria Consortium is an international non-profit organization based in Cambridge Heath, London, specializing in the comprehensive control of malaria and other communicable diseases – particularly those affecting children under five.
The London Declaration on Neglected Tropical Diseases was a collaborative disease eradication programme launched on 30 January 2012 in London. It was inspired by the World Health Organization roadmap to eradicate or prevent transmission for neglected tropical diseases by the year 2020. Officials from WHO, the World Bank, the Bill & Melinda Gates Foundation, the world's 13 leading pharmaceutical companies, and government representatives from US, UK, United Arab Emirates, Bangladesh, Brazil, Mozambique and Tanzania participated in a joint meeting at the Royal College of Physicians to launch this project. The meeting was spearheaded by Margaret Chan, Director-General of WHO, and Bill Gates, Co-Chair of the Bill & Melinda Gates Foundation.
Mass deworming, is one of the preventive chemotherapy tools, used to treat large numbers of people, particularly children, for worm infections notably soil-transmitted helminthiasis, and schistosomiasis in areas with a high prevalence of these conditions. It involves treating everyone – often all children who attend schools, using existing infrastructure to save money – rather than testing first and then only treating selectively. Serious side effects have not been reported when administering the medication to those without worms, and testing for the infection is many times more expensive than treating it. Therefore, for the same amount of money, mass deworming can treat more people more cost-effectively than selective deworming. Mass deworming is one example of mass drug administration.
Trematodiasis is a group of parasitic infections due different species of flukes, the trematodes. Symptoms can range from mild to severe depending on the species, number and location of trematodes in the infected organism. Symptoms depend on type of trematode present, and include chest and abdominal pain, high temperature, digestion issues, cough and shortness of breath, diarrhoea and change in appetite.

The Kigali Declaration on Neglected Tropical Diseases is a global health project that aims to mobilise political and financial resources for the control and eradication of infectious diseases, the so-called neglected tropical diseases due to different parasitic infections. Launched by the Uniting to Combat Neglected Tropical Diseases on 27 January 2022, it was the culmination and join commitment declared at the Kigali Summit on Malaria and Neglected Tropical Diseases (NTDs) hosted by the Government of Rwanda at its capital city Kigali on 23 June 2022.
Gastropod-borne parasitic diseases (GPDs) are a group of infectious diseases that require a gastropod species to serve as an intermediate host for a parasitic organism that can infect humans upon ingesting the parasite or coming into contact with contaminated water sources. These diseases can cause a range of symptoms, from mild discomfort to severe, life-threatening conditions, with them being prevalent in many parts of the world, particularly in developing regions. Preventive measures such as proper sanitation and hygiene practices, avoiding contact with infected gastropods and cooking or boiling food properly can help to reduce the risk of these diseases.
The END Fund is a private non-profit organisation dedicated to combating the five most common neglected tropical diseases (NTDs) that cause up to 90% of the NTD burden in Sub-Saharan Africa.
