Global Network For Neglected Tropical Diseases
The Global Network for Neglected Tropical Diseases is an advocacy initiative of the Sabin Vaccine Institute dedicated to raising the awareness, political will, and funding necessary to control and eliminate the most common Neglected Tropical Diseases (NTDs)—a group of disabling, disfiguring, and deadly diseases affecting more than 1.4 billion people worldwide living on less than $1.25 a day. The Global Network provides an advocacy platform for the broad NTD community that reaches the attention of policymakers, philanthropists, thought leaders, and the general public. Through that platform, the Global Network highlights the work—including implementation, research, advocacy, and policy efforts—of the NTD community at the local, national, and international levels. The Global Network collaborates closely with the World Health Organization and other technical agencies, NGOs, donors, and the broader public health community; together they support international organizations, gover ...

Non-governmental Organization
A non-governmental organization (NGO) or non-governmental organisation (see American and British English spelling differences#-ise, -ize (-isation, -ization), spelling differences) is an organization that generally is formed independent from government. They are typically nonprofit organization, nonprofit entities, and many of them are active in humanitarianism or the social sciences; they can also include club (organization), clubs and voluntary association, associations that provide services to their members and others. Surveys indicate that NGOs have a high degree of public trust, which can make them a useful proxy for the concerns of society and stakeholders. However, NGOs can also be lobby groups for corporations, such as the World Economic Forum. NGOs are distinguished from International organization, international and intergovernmental organizations (''IOs'') in that the latter are more directly involved with sovereign states and their governments. The term as it is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HIV/AIDS
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss. HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated blood transfusions, hypodermic needles, and from mother to ch ...

Onchocerciasis
Onchocerciasis, also known as river blindness, is a disease caused by infection with the parasitic worm ''Onchocerca volvulus''. Symptoms include severe itching, bumps under the skin, and blindness. It is the second-most common cause of blindness due to infection, after trachoma. The parasite worm is spread by the bites of a black fly of the ''Simulium'' type. Usually, many bites are required before infection occurs. These flies live near rivers, hence the common name of the disease. Once inside a person, the worms create larvae that make their way out to the skin, where they can infect the next black fly that bites the person. There are a number of ways to make the diagnosis, including: placing a biopsy of the skin in normal saline and watching for the larva to come out; looking in the eye for larvae; and looking within the bumps under the skin for adult worms. A vaccine against the disease does not exist. Prevention is by avoiding being bitten by flies. This may include t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trachoma
Trachoma is an infectious disease caused by bacterium '' Chlamydia trachomatis''. The infection causes a roughening of the inner surface of the eyelids. This roughening can lead to pain in the eyes, breakdown of the outer surface or cornea of the eyes, and eventual blindness. Untreated, repeated trachoma infections can result in a form of permanent blindness when the eyelids turn inward. The bacteria that cause the disease can be spread by both direct and indirect contact with an affected person's eyes or nose. Indirect contact includes through clothing or flies that have come into contact with an affected person's eyes or nose. Children spread the disease more often than adults. Poor sanitation, crowded living conditions, and not enough clean water and toilets also increase spread. Efforts to prevent the disease include improving access to clean water and treatment with antibiotics to decrease the number of people infected with the bacterium. This may include treating, al ...

Elephantiasis Tropica
Lymphatic filariasis is a human disease caused by parasitic worms known as filarial worms. Usually acquired in childhood, it is a leading cause of permanent disability worldwide. While most cases have no symptoms, some people develop a syndrome called elephantiasis, which is marked by severe swelling in the arms, legs, breasts, or genitals. The skin may become thicker as well, and the condition may become painful. Affected people are often unable to work and are often shunned or rejected by others because of their disfigurement and disability. It is the first of the mosquito-borne diseases to be have been identified. The worms are spread by the bites of infected mosquitoes. Three types of worms are known to cause the disease: ''Wuchereria bancrofti'', ''Brugia malayi'', and ''Brugia timori'', with ''Wuchereria bancrofti'' being the most common. These worms damage the lymphatic system. The disease is diagnosed by microscopic examination of blood collected during the night. Th ...

Snail Fever
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. The disease is spread by contact with fresh water contaminated with the parasites. These parasites are released from infected freshwater snails. The disease is especially common among children in developing countries, as they are more likely to play in contaminated water. Other high-risk groups include farmers, fishermen, and people using unclean water during daily living. It belongs to the group of helminth infections. Diagnosis is by finding eggs of the parasite in a person's urine or stool. It can also be confirmed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hookworm
Hookworms are intestinal, blood-feeding, parasitic roundworms that cause types of infection known as helminthiases. Hookworm infection is found in many parts of the world, and is common in areas with poor access to adequate water, sanitation, and hygiene. In humans, infections are caused by two main species of roundworm, belonging to the genera ''Ancylostoma'' and '' Necator''. In other animals the main parasites are species of ''Ancylostoma''. Species The two most common types of hookworm that infect humans are ''Ancylostoma duodenale'' and '' Necator americanus''. Hookworm species that are known to infect domestic cats are '' Ancylostoma braziliense'' and '' Ancylostoma tubaeforme''. Wild cats are infected by '' Ancylostoma pluridentatum''. Dogs are commonly infected by '' Ancylostoma caninum'', but may also be infected by '' Uncinaria stenocephala'' and ''Ancylostoma braziliense''. In Asia, '' Ancylostoma ceylanicum'' is endemic among dogs and cats and infects humans. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whipworm
''Trichuris trichiura, Trichocephalus trichiuris'' or whipworm, is a parasitic roundworm (a type of helminth) that causes trichuriasis (a type of helminthiasis which is one of the neglected tropical diseases) when it infects a human large intestine. It is commonly known as the ''whipworm'' which refers to the shape of the worm; it looks like a whip with wider "handles" at the posterior end. Life cycle The female ''T. trichiura'' produces 2,000–10,000 single-celled eggs per day. Eggs are deposited from human feces to soil where, after two to three weeks, they become embryonated and enter the "infective" stage. These embryonated infective eggs are ingested by hand-mouth or through formites and hatch in the human small intestine, exploiting the intestinal microflora as a stimulus to hatching. This is the location of growth and molting. The infective larvae penetrate the villi and continue to develop in the small intestine. The young worms move to the caecum and penetrate the ...

Trichuriasis
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. The disease is usually spread when people eat food or drink water that contains the eggs of these worms. This may occur when contaminated vegetables are not fully cleaned or cooked. Often these eggs are in the soil in areas where people defecate outside and where untreated human feces is used as fertilizer. These eggs originate from the feces of infected people. Young children playing in such soil and putting their hands in their mouths also become infected easily. The worms live in the large bowel and are about four centimetr ...

Ascaris Lumbricoides
''Ascaris lumbricoides'' is a large parasitic worm that causes ascariasis in humans. A roundworm of genus '' Ascaris'', it is the most common parasitic worm in humans. An estimated one-sixth of the human population is at some point infected by a roundworm such as ''A. lumbricoides''; people living in tropical and subtropical countries are at greater risk of infection. It has been proposed that ''Ascaris lumbricoides'' and ''Ascaris suum'' (pig roundworm) are the same species. Lifecycle ''Ascaris lumbricoides'', a roundworm, infects humans via the fecal-oral route. Eggs released by adult females are shed in feces. Unfertilized eggs are often observed in fecal samples but never become infective. Fertilized eggs embryonate and become infectious after 18 days to several weeks in soil, depending on the environmental conditions (optimum: moist, warm, shaded soil).Parasites - Ascariasis.
