Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

Lymphatic filariasis (LF) infection if untreated results in fluid accumulation in the limbs or breasts (lymphedema) or genitalia (hydrocele) that is painful and causes great discomfort. Morbidity management and disability prevention (MMDP) strategies such as surgery for hydrocele, treatment of acute... attacks and management of lymphedema are necessary for the management of the advanced stages of LF. However, very few countries including Zambia, have adequate information on the health beliefs and health seeking behavior of communities living in endemic areas towards MMDP services for LF. This study sought to explore community and health provider perspectives towards MMDP services for LF in a highly endemic region, Luangwa District, Zambia, between February and April 2019.

At the forefront of DNDi’s efforts to develop new treatments is the need to understand the realities and treatment needs of patients and health care staff in the field. The ultimate goal for human African trypanosomiasis (HAT) is a truly simplified
treatment which can be orally administered, impl...emented at the primary health care level, and effective against both stages of the disease.

Schistosomiasis is widely recognized as a disease that is socially determined. An understanding of the social and behavioural factors linked to disease transmission and control should play a vital role in designing policies and strategies for schistosomiasis prevention and control. To this must be a...dded the awareness that schistosomiasis is also a disease of poverty. It still survives in poverty-stricken, remote areas where there is little or no safe water or sanitation, and health care is scarce or non-existent. For a variety of complex reasons, many of which are addressed in this book, the disease is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural China. This concern for human behaviour in an environment of poverty echoes the concerns of the new research priority for “diseases of poverty” identified by the Special Programme for Research & Training in Tropical Diseases.

Schistosomiasis is a neglected tropical disease of global medical and veterinary importance. As efforts to eliminate schistosomiasis as a public health problem and interrupt transmission gather momentum, the potential zoonotic risk posed by livestock Schistosoma species via viable hybridisation in s...ub-Saharan Africa have been largely overlooked. We aimed to investigate the prevalence, distribution, and multi-host, multiparasite transmission cycle of Haematobium group schistosomiasis in Senegal, West Africa.

States have committed and assumed obligations to address multiple and intersecting forms of discrimination against refugees, internally displaced persons, asylum seekers, returnees and stateless persons. The Global Compact on Refugees places ending discrimination of any kind based on the grounds of ...race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth, disability, age, or other status at the centre of action to prevent displacement and to ensure peaceful coexistence between refugee and host communities. Narratives about cultural diversity and inclusion are important, but there is also a pressing need in many societies for conversations and action to address racism, racial discrimination, xenophobia and related intolerance.

The Food and Agriculture Organization of the United Nations (FAO) launched a new Framework for Environmental and Social Management (FESM) to ensure that both people and the environment are protected from any potential impacts of FAO programmes and projects.
“This Framework ensures that our proj...ects do both “no harm” and support the transformation to more efficient, more inclusive, more resilient and more sustainable agrifood systems by upholding the highest international standards for risk management,” FAO Director-General QU Dongyu explained during a virtual event.
The Framework, which includes key elements of a people-centered approach and establishes environmental and social performance requirements for FAO programming, is also intended to ensure that all stakeholders, including local and indigenous communities, have ample opportunities to actively participate in projects’ activities and to voice their concerns about them.

Conflicts and disasters, including pandemics, affect women and men in all their diversity differently, and women and girls often suffer the most. Crisis-related hardships combine and compound pre-existing disadvantages, for example, they often cause women’s working conditions to worsen while incre...asing their overall workload and care responsibilities. At the same time, crises can give rise to changes that enable women to take up roles that were previously available only to men, and crises can open opportunities to address existing gender-based discrimination and violations of rights.

Human schistosomiasis, a parasitic and often chronic illness, is one of the major neglected tropical diseases worldwide. It is estimated that 240 million people suffer from schistosomiasis, with more than 200000 fatalities recorded each year. Schistosomiasis is caused by an infection of the blood fl...uke Schistosoma and is transmitted to humans through direct contact with infected water.

The introduction of vaccines for coronavirus disease 2019 (COVID-19) added another measure to the existing set of
recommended preventive measures (wearing a mask in public, keeping a distance from other people and regular handwashing). The roll-out of the vaccines, however, raised concerns that vac...cination may lead to lower adherence to the existing
preventive measures. The advice from the World Health Organization (WHO) was to continue these public health and
social measures after being vaccinated.1 However, evidence from other epidemics suggests that there is lower adherence to
preventive measures when some level of protection exists (for example, individuals who use human immunodeficiency virus
pre-exposure prophylaxis

A wide spectrum of disease severity has been described for Human African Trypanosomiasis (HAT) due to
Trypanosoma brucei rhodesiense (T.b. rhodesiense), ranging from chronic disease patterns in southern countries of East Africa to an increase in virulence towards the north. However, only limited d...ata on the clinical presentation of T.b. rhodesiense HAT is available. From 2006-2009 we conducted the first clinical trial program (I MPAMEL III) in T.b. rhodesiense endemic areas of
Tanzania and Uganda in accordance with international standards (ICH-GCP). The primary and secondary outcome measures were safety and efficacy of an abridged melarsoprol schedule for treatment of second stage disease. Based on diagnostic findings and clinical examinations at baseline we describe the clinical presentation of T.b. rhodesiense HAT in second stage patients from two distinct geographical settings in East Africa.

Arsenical monotherapies were previously very successful for treating human African trypanosomiasis (HAT).
Melarsoprol resistance emerged as early as the 1970s and was widespread by the late 1990s.
Melarsoprol resistance represents the only example of widespread drug resistance in HAT patients wher...e the genetic mechanism has been established.
The current goal of elimination of HAT as a public health problem by 2020 may be undermined by the emergence and spread of resistance to current or new drugs.
Insights into potential resistance mechanisms for current and new drugs will facilitate predictions of the likelihood of resistance and will also facilitate rational approaches to minimizing, monitoring, and tackling the future emergence of resistance.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.
