Schistosomiasis, which is the second most important parasitic infection after malaria in terms of its socioeconomic impact, is responsible for the loss of an estimated 4.5 million disability-adjusted life years (DALYs) worldwide. Schistosomiasis, in...cluding both intestinal and urinary forms of the disease, occurs in 78 countries across the globe. An estimated 240 million people are infected, with more than 779 million living at risk globally. The majority of those infected and those at risk for infection live in low-income countries, and approximately 80% of the morbidity occurs in impoverished communities and households in sub-Saharan Africa. Within Uganda, 91 of the 134 districts are endemic for intestinal schistosomiasis caused by Schistosoma mansoni, and the eastern region, especially along Lake Victoria, has one of the highest S. mansoni burdens worldwide. Schistosoma haematobium is only endemic in the five districts of the Lango region in northern Uganda.

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 ... medbox">parasitic disease. The parasites that cause schistosomiasis live in certain types of freshwater 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.

Human African trypanosomiasis (HAT), also called sleeping sickness, is a parasitic infection that almost invariably progresses to death, unless treatment is provided. HAT caused devastating epidemics during the 20th century. Thanks to sustained and ...coordinated efforts during the past 15 years the number of reported cases has fallen to a historic low. Fewer than 3,000 cases were reported in 2015, and the disease is targeted for elimination by the World Health Organization. Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

Leishmaniasis is a vector-borne disease with a wide variety of parasite species, reservoirs, and vectors involved in transmission. It is caused by different species of the protozoa Leishmania and is transmitted to animals and humans through a bite o...f insects in the Psychodidae family. Its presence is directly linked to poverty, but social, environmental, and climatalogic factors directly influence the disease's epidemiology.

There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan parasites which are tra...nsmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

El ciclo de transmisión
Teniasis. Las tenias viven en los intestinos de las personas infectadas. Los huevos de la tenia se liberan con las heces. Si se defeca al aire libre, se puede contaminar el ambiente (incluyendo los vegetales y el agua). Cisticercosis humana. La inges...tión de huevos de la tenia (debido a una mala higiene después de ir al baño o al consumir alimentos o agua contaminados), resulta en quistes del parásito principalmente en el cerebro (causando convulsiones y epilepsia). Cisticercosis porcina. Los cerdos que ingieren huevos de tenia (presentes en las heces o en el medio ambiente) desarrollan quistes del parásito, principalmente en los músculos (carne). La carne infectada contiene quistes del parásito, que no siempre son fáciles de ver. Comer carne de cerdo infectada cruda o poco cocinada hará que las personas desarrollen tenias.
Las medidas de prevención y control
Tratar la infección por teniasis con medicamentos indicados por el personal de salud. Lavarse las manos con agua y jabón después de ir al baño. Lavar bien las verduras o cocinarlas antes de comerlas. Utilizar los baños o letrinas para evitar infectar el ambiente, los cerdos y otras personas. Mantener a los cerdos en corrales para evitar que se infecten. Vacunar y tratar a los cerdos para prevenir la infección. La inspección de la carne puede identificar a los cerdos altamente infectados. Cocinar bien la carne de cerdo (no debe verse el color rosa) para matar el parásito.
