Les progrès remarquables réalisés dans la lutte contre la forme à T. b. gambiense reposent sur le dépistage et le traitement curatif, une stratégie qui interrompt la transmission en réduisant le réservoir de parasites chez l’être humain. Parfois, cette
approche a été combinée avec des... activités de lutte antivectorielle. L’objet de ces lignes directrices est donc de la plus haute importance pour la poursuite des progrès en vue de l’élimination de la THA.

Leishmaniasis is a vector-borne disease with a broad global distribution and an increasing number of recorded cases worldwide. However, it is still one of the world's most neglected diseases. Over the last decades, the disease has been found to expand geographically with a global increase of cases o...f visceral and cutaneous leishmaniasis increasing the public health problems associated with the disease epidemics. The reported range expansion of the diseases has been associated with range expansions of vector populations in response to climate change. Leishmaniasis is caused by protozoan parasites of the genus Leishmania. The transmission can either be zoonotic and/or anthroponotic through the bite of an infected female phlebotomine sandfly. In Eurasia and Africa, all vector-competent sandfly species belong to the genus Phlebotomus. Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis. In the ‘old world’, it is caused by five currently recognized Leishmania species: L. major, L. tropica and L. aethiopica (being main causative parasites) as well as L. infantum and L. donovani. Visceral leishmaniasis (VL), another common and more severe form of leishmaniasis, is only associated with the Leishmania species L. infantum and L. donovani. The specific Leishmania species cause different clinical symptoms in humans.

This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.
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.

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Advice and guidance on the health needs of migrant patients for healthcare practitioners.
Chagas disease is increasingly reported in Latin American migrants who have settled in Europe. It has rarely been reported in the UK due to lack of testing and awareness.
Chagas disease (American trypanosomia...sis) is a zoonosis caused by the flagellate protozoan parasite Trypanosoma cruzi.

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.

Issue Brief 31: Antimicrobial resistance (AMR) can occur when viruses, bacteria, parasites and fungi change over time. There is no longer a response to medicines, and the infection treatment gets really difficult which increases the risk of a disesase spread, which can lead to severe health problems.... AMR is an increasing threat to global public health worldwide that requires cross-sectional and cross-disciplinary action. It is present in every country and is spurred by several human-made factors, including over- and/or inadequate use of antibiotics, poor hygiene and infection prevention control, and excessive usage of antibiotics outside the health care sector e.g. in life stock production.

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.

Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection
occurs when filarial parasites are transmitted to humans through mosquitoes. When a mosquito
with infective stage larvae bites a person, the parasites are deposited on the person’s skin from
where ...they enter the body. The larvae then migrate to the lymphatic vessels where they develop
into adult worms in the human lymphatic system.

The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

Antimicrobial resistance (AMR) is one of the top 10 global public health threats facing humanity. AMR threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi.
It occurs when microorganisms develop resistance to me...dicines that are relied upon for treatment, making some conditions difficult or impossible to cure. As a result, infections persist in the body, increasing the risk of disease spread, severe illness and death.
The Antimicrobial Resistance channel offers learning resources to support implementation of the Global Action Plan on AMR (2015), by building health care worker competencies to help combat AMR in their daily clinical practice.

Antimicrobial resistance (AMR) is described as a situation when bacteria, viruses, fungi and parasites
change over time and no longer respond to medicines, making infections harder or impossible to treat,
and increasing the risk of disease spread, severe illness and death.1 AMR in recent years has... become
a global priority in public health due to its widespread consequences and increasing occurrence from
time to time. AMR has a formidable impact where the existing antibiotics and other antimicrobial
medicines become ineffective, and infections become increasingly difficult or impossible to treat.

Antimicrobial resistance (AMR) represents a major global threat across human, animal, plant food and environmental sectors, threatening the effective treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi, resulting in prolonged illness and increased mor...tality, often felt hardest by the most vulnerable populations. AMR also endangers the sustainability of agri-food systems and food safety.
Since 2010 there is a strong commitment from FAO, OIE and PAHO to fight AMR, working together to mitigate the risks in the interconnection among the human health, animal health and the environment. In this context, the organizations now joined forces in the implementation of the project ‘Working Together to Fight Antimicrobial Resistance’ to ensure a coherent “One Health” approach recognizing the multidimensionality and necessity of an intersectoral response that is needed to address the problem of AMR.
The overall strategic objective of the three-year project (2020-22) supported and financed by the European Union (EU) is to contribute to tackle AMR through the implementation of National AMR Action Plans by working with seven Latin American partner countries: Argentina, Brazil, Chile, Colombia, Paraguay, Peru and Uruguay.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

Washing hands is the best way to prevent the spread of germs and diseases. Dirty hands can carry pathogenic germs that can sicken a person or spread diseases to others. Microorganisms such as bacteria, viruses, parasites, fungi and various chemicals can enter our bodies directly when we touch our fa...ce, eyes, nose or mouth or may enter indirectly, when our dirty hands stain surfaces touched by others or where food is prepared. The habit of washing hands with soap and water constitutes the first line of defense against the spread of many diseases, from the common cold or diarrhea to more serious illnesses such as meningitis, influenza or hepatitis as well as many other diseases. This 2-D animation describes the importance of hand washing.
