Education and information about Chagas Disease epidemiology and risk factors.
La enfermedad de Chagas, también conocida como tripanosomiasis americana, es causada por el parásito Trypanosoma cruzi. La forma más común de contraer la infección es a través del contacto con las heces de un insecto triatominio (conocido con los nombres de chinche besucona, benchuca, vinchuca..., chipo o barbeiro), el cual se alimenta de la sangre de seres humanos y animales.

In 2016, PAHO's Directing Council, through Resolution CD55.R9, approved the “Plan of Action for Elimination of Neglected Infectious Diseases (NID) and Post-Elimination Actions, 2016-2022.” This Resolution urges Member States to implement a set of interventions to reduce the burden of disease by ...NID in the Americas by 2022, including “…support promotion of treatment, rehabilitation, and related support services through an approach focused on integrated morbidity management and disability prevention for individuals and families afflicted by those neglected infectious diseases that cause disability and generate stigma.” NIDs can have devastating chronic sequelae for patients, such as disability, visible change or loss in body structure, loss of tissue, and impairment of proper tissue and organ function, among others. All of these can in turn lead to unjustified discrimination, stigmatization, mental health problems, and partial or total incapacity to work, perpetuating the vicious cycle of neglected diseases as both a consequence and a cause of poverty. Patients with chronic conditions caused by NIDs require proper health care in order to prevent further damage and improve their living and social conditions. This should be provided at the primary health care level, as patients suffering from NIDs are often unable to travel to or afford to pay for specialized care services. Care for patients suffering from chronic morbidity caused by NID should be integrated into care for other chronic conditions caused by non-communicable diseases. This manual provides a framework for morbidity management and disability prevention of patients affected by NIDs and gives specific guidance for the proper care of patients suffering from chronic conditions caused by lymphatic filariasis, leprosy, trachoma, and Chagas disease. It is intended to be used mainly by health care workers at the primary health care level, but health workers at more complex and specialized levels may also find it useful.

A systematic review of clinical and observational antiparasitic treatment studies to assess the potential for establishing an individual participant-level data platform.
Chagas disease (CD), caused by the parasite Trypanosoma cruzi, affects ~6–7 million people worldwide. Significant limitations s...till exist in our understanding of CD. Harnessing individual participant data (IPD) from studies could support more in-depth analyses to address the many outstanding research 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.

Vectors can be a threat to you, at home and when travelling.
Simple measures for protection.
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 tropical disease caused by a parasite called Trypansoma cruzi and is primarily spread by Triatomine bugs. It is estimated to affect 6-7 million people, mostly in Latin America, and can cause devastating chronic illness. In this video we take a look at the disease, what it is, and... ways to control its spread.

Information for the General Public
Progress towards achieving the Roadmap targets for control and elimination of the Neglected Tropical Diseases.
Chikungunya: WHO fact sheet on Chikungunya providing key facts and information on scope of the problem, who is at risk, prevention, WHO response.
Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

Goal and objectives of the guideline
The goal of this guideline is to provide evidence-based recommendations to countries in their efforts to accomplish schistosomiasis morbidity control and elimination as a public health problem, and to move towards interruption of transmission.
The recommendatio...ns contained herein will help countries to implement national schistosomiasis control and elimination programmes and support efforts to verify the interruption of transmission.
The specific objectives are to provide guidance on:
prevalence thresholds, target age groups and frequency of preventive chemotherapy for schistosomiasis;
establishment of water, sanitation and hygiene (WASH) and snail control activities to support control and elimination of schistosomiasis;
use of diagnostic tests in humans in low transmission areas and for moving to, and evaluating the interruption of transmission of schistosomiasis;
tools for the assessment of Schistosoma spp. infection in snail hosts; and
diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs of infection

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.

Onchocerciasis, or river blindness, is a neglected tropical disease (NTD) caused by the parasitic worm Onchocerca volvulus. It is transmitted through repeated bites by blackflies of the genus Simulium. The disease is called river blindness because the blackfly that transmits the infection lives and ...breeds near fast-flowing streams and rivers, mostly near remote rural villages. The infection can result in visual impairment and sometimes blindness. Additionally, onchocerciasis can cause skin disease, including intense itching, rashes, or nodules under the skin. Worldwide onchocerciasis is second only to trachoma as an infectious cause of blindness.

A dermatologist can often diagnose scabies by visually examining a patient’s skin from head to toe.
To make sure that a patient has scabies, a dermatologist may remove some skin. This is painless. Your dermatologist will put the skin on a glass slide and look at the slide under a microscope. If y...our dermatologist sees scabies mites or their eggs, it is certain that you have scabies.

Scabies is caused by Sarcoptes scabiei, a mite which lays its eggs under the surface of your skin and reproduces. When the eggs hatch, mites crawl out onto your skin and make new burrows.
The mites can be difficult to identify and may be confused with pubic lice as both conditions cause itching in ...the genital area.

Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs.
Scabies is found worldwide and affects people of all races and social classes. Scabi...es can spread rapidly under crowded conditions where close body and skin contact is frequent. Institutions such as nursing homes, extended-care facilities and prisons are often sites of scabies outbreaks. Child care facilities also are a common site of scabies infestations.
