El presente decálogo expone de manera concisa los aspectos esenciales de la enfermedad y recoge 10 puntos básicos, esquemáticos y orientados a la práctica para la atención pediátrica de la enfermedad de Chagas.
About six to seven million people worldwide, mostly in Latin America, are estimated to be infected with
Trypanosoma cruzi, the parasite that causes Chagas disease (WHO data from 2021). Chagas disease is
found mainly in endemic areas of 21 Latin American countries. Chagas disease was once entirely
...
confined to rural areas but in the last decades, due to population movements, most infected people live
in urban settings and the disease has spread to other continents. The burden of disease is due to its
chronic progression with people still suffering years later after initial infection.

Today is World Chagas Disease Day. This year’s theme is Finding and reporting every case to defeat Chagas disease.
Despite progress, the global case detection rate for Chagas disease is low (estimated to be around 10%), posing a substantial barrier to accessing treatment and care and in prevent...ing transmission.
Often termed as a “silent and silenced disease”, many people with Trypanosoma cruzi infection (the parasite that causes the disease) develop no symptoms or unspecific mild symptoms. Moreover, many countries with cases lack systems to track the number of affected people and active transmission routes.

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.

Leishmaniasis is an important worldwide disease with a
zoonotic potential that presenting visceral and cutaneous
clinical forms. The domestic dog is seen as the main reservoir of Leishmania spp. and for this reason, it is the target of
the control program in some countries. The health professiona...ls’ knowledge about prevention and control of leishmaniasis was investigated. Through interviews with health
professionals from endemic regions, it was observed that
there are several conceptuais gaps about leishmaniasis.
Therefore, it is essential to put into practice the concepts
of single health, bringing human, animal and environmental
health, next to population.

Leishmaniasis is a parasitic disease caused by the Leishmania parasite. This parasite typically lives in infected sand flies. You can contract leishmaniasis from a bite of an infected sand fly.
The sand flies that carry the parasite typically reside in tropical and subtropical environments. Fatal... epidemics have occurred in areas of Asia, East Africa, and South America.
Affected regions are often remote and unstable, with limited resources for treating this disease. Doctors Without Borders calls leishmaniasis one of the most dangerous neglected tropical diseases. The organization also states this disease is second only to malaria in parasitic causes of death.

Leishmaniasis is a parasitic disease caused by intracellular protozoan parasites of the genus Leishmania (Trypanosomatidae family); it is endemic in more than 98 countries worldwide [1]. Visceral (VL) and cutaneous (CL) leishmaniasis are the most common forms of the disease. VL causes a systemic dis...ease characterised by fever, hepatosplenomegaly, anaemia and lymph node enlargement and may be fatal without appropriate treatment, while CL mainly causes skin ulcers and is considered a less severe form of the disease [2]. The incubation period for VL varies from 10 days up to nearly 3 years and for CL from 2 weeks to 3 years [3]. The natural route of transmission is a bite of blood-feeding phlebotomine sandflies; it may be zoonotic or anthroponotic, depending on the parasite species and the geographical location

Leishmaniasis is an infection caused by the Leishmania parasites. The infection is transmitted by the bite of infected phlebotomine sandfly. There are over 20 types of Leishmania parasites which cause infection in people and 30 different types of sand flies to spread infection. Leishmaniasis is wide...ly distributed throughout Central and South America, the Middle East, Africa and southern Europe.

Each year 1–2 million people are diagnosed with a tropical disease called leishmaniasis, which is caused by single-celled parasites. People are infected when they are bitten by sandflies carrying the parasite, and often develop skin lesions around the bite site. Though mild cases may recover on th...eir own or with treatment, sometimes the parasites multiply and spread elsewhere causing further skin lesions and facial disfigurement. Furthermore, the parasites can also infect internal organs such as the spleen and the liver, which without treatment can be fatal.

No vaccines or drugs to prevent infection are available. The best way for travelers to prevent infection is to protect themselves from sand fly bites. To decrease the risk of being bitten, follow these preventive measures:
Avoid outdoor activities, especially from dusk to dawn, when sand flies ge...nerally are the most active.
