Leishmaniasis is a vector-borne disease that is transmitted by sandflies and caused by obligate intracellular protozoa of the genus Leishmania. Human infection is caused by about 21 of 30 species that infect mammals. These include the L. donovani complex with 3 species (L. donovani, L. infantum, and... L. chagasi); the L. mexicana complex with 3 main species (L. mexicana, L. amazonensis, and L. venezuelensis); L. tropica; L. major; L. aethiopica; and the subgenus Viannia with 4 main species (L. (V.) braziliensis, L. (V.) guyanensis, L. (V.) panamensis, and L. (V.) peruviana). The different species are morphologically indistinguishable, but they can be differentiated by isoenzyme analysis, molecular methods, or monoclonal antibodies.

Trachoma is one of oldest infectious diseases known to humans. It is caused by the bacteria Chlamydia trachomatis, which is transmitted through contact with eye secretions of infected people (shared use of towels and handkerchiefs, contact with fingers, etc.), as well by flies that help spread it.
Trachoma disease
Trachoma is a sequela following infection by the bacterium Chlamydia trachomatis (C. trachomatis). The disease is preventable, but still the cause of blindness in 1.9 million people world wide.
Trachoma is a bacterial eye infection, not unlike the common ‘pink-eye’ or conjunctivitis. Repeated reinfection, combined with the body’s immune reaction, often has devastating consequences.
Trachoma starts as an infection of the membrane that covers the outside of the eyeball and lines th...e inner surface of the eyelids (conjunctiva). Repeated infections can over years eventually lead to scarring that causes the margin of the eyelid to turn inwards.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Chagas disease is a parasitic zoonosis caused by Trypanosoma cruzi, a protozoan whose transmission to humans is primarily vector-borne. It is estimated that 6–8 million people worldwide are inf...ected and that 65–100 million people are at risk of becoming infected. Its clinical spectrum is very broad. During the acute phase, non-specific manifestations develop that may go unnoticed. During the chronic phase, specific manifestations develop that are diagnosed late and increase the morbidity and mortality of those suffering from it.

It is estimated that, in Latin America alone, between 6 and 8 million people are infected with the parasite, and 99% of these are not receiving treatment, either because they are unaware of their infection or because they do not know that treatment exists. The potential spread of the disease is also... a cause for considerable concern: 65 million people live in areas of exposure and are at risk of contracting Chagas disease, and 28,000 new cases occur every year.

In areas of Mexico, Central America, and South America, where the Trypanosoma cruzi parasite is present in triatomine bugs, improved housing and spraying insecticide inside housing to eliminate the bugs has significantly decreased the spread of Chagas disease. Screening of blood donations for Chagas... is another important public health tool to help prevent spreading the disease through blood transfusions. Early detection and treatment of new cases, including mother-to-baby (congenital) cases, will also help reduce the burden of disease.

Chagas disease is a tropical parasitic infection transmitted by crawling, blood-sucking insects (kissing bugs). You may have flu-like symptoms or none at all. But the disease can lead to life-threatening complications. With prompt treatment, most people with Chagas disease, also known as American tr...ypanosomiasis, recover fully.

The Triatominae are vectors for Trypanosoma cruzi, the aetiological agent of the neglected tropical Chagas disease. Their distribution stretches across Latin America, with some species occurring outside of the Americas. In particular, the cosmopolitan vector, Triatoma rubrofasciata, has already been... detected in many Asian and African countries. We applied an ensemble forecasting niche modelling approach to project the climatic suitability of 11 triatomine species under current climate conditions on a global scale. Our results revealed potential hotspots of triatomine species diversity in tropical and subtropical regions between 21 ̊N and 24 ̊S latitude. We also determined the climatic suitability of two temperate species (T. infestans, T. sordida) in Europe, western Australia and New Zealand. Triatoma rubrofasciata has been projected to find climatically suitable conditions in large parts of coastal areas throughout Latin America, Africa and Southeast Asia, emphasising the importance of an international vector surveillance program in these regions.

Chagas disease (CD), caused by the parasite Trypanosoma cruzi, affects ~6–7 million people worldwide. Significant limitations still exist in our understanding of CD. Harnessing individual participant data (IPD) from studies could support more in-depth analyses to address
the many outstanding rese...arch questions. This systematic review aims to describe the characteristics and treatment practices of clinical studies in CD and assess the breadth and
availability of research data for the potential establishment of a data-sharing platform.

Chagas disease is caused by Trypanosoma cruzi, a protozoal organism primarily transmitted by triatomine insect vectors, also known as “kissing bugs.” It is a zoonotic disease originally described by Brazilian physician Dr. Carlos Chagas in 1909 and is widespread in Latin America. Although triato...mines and T. cruzi have long been endemic to the southern United States, awareness and identification of infected vectors and animals have recently increased throughout the United States. Canine Chagas disease can be acute or chronic and is predominantly characterized by inflammation and fibrosis of the heart, resulting in arrhythmias, myocardial dysfunction, heart failure, and sudden death, although many infected dogs are asymptomatic.

There are currently 4 different serotypes of Dengue virus known to science. Each time someone get infected and recovers, the individual will be protected by a lifelong immunity from further infection against that specific serotype and that serotype only.
Consequent infection from different serotype... not only will infect the individual but may also cause a more serious or severe disease progression.

Chagas disease is a zoonosis caused by the protozoa Trypanosoma cruzi. It is transmitted to humans by contact of triatomine bug faeces with a break in the skin (often caused by a bite from the triatomine bug), or with mucous membranes. Transmission by contaminated blood transfusion, accidental expos...ure to blood, mother-to-child (during pregnancy or childbirth) or consumption of contaminated food and water is also possible.
Chagas disease has two phases: an acute phase, which lasts approximately 4 to 6 weeks, and a chronic phase, which is lifelong if left untreated.
The disease is primarily found on the American continent. It is significantly underdiagnosed.

Dies ist der siebte Bericht über die Entwicklung der Menschenrechtssituation in Deutschland, den das Deutsche Institut für Menschenrechte („Institut“) jährlich dem Bundestag vorlegt. Der Bericht befasst sich in diesem Jahr vertieft mit dem Recht auf Bildung von Kindern und Jugendlichen mit Be...hinderungen. Wir analysieren die Frage, wie und mit welchem Instrumentarium Deutschland ein inklusives Schulsystem für alle schaffen kann. Denn dazu verpflichtet die UN-Behindertenrechtskonvention.
Hier sehen wir Bund und Länder gemeinsam in der Pflicht. Darüber hinaus greift der Bericht fünf weitere Themen auf, die im Berichtszeitraum (01. Juli 2021–30. Juni 2022) von hoher menschenrechtlicher Relevanz waren. Dabei stellen wir einerseits Entwicklungen in diesen Themenfeldern dar, andererseits bewerten wir wichtige politische und gesetzgeberische Maßnahmen menschenrechtlich und formulieren Empfehlungen.
