Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

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.

Female Genital Schistosomiasis (FGS) is a gynaecological disease caused by Schistosoma haematobium, a parasitic worm that is acquired by skin contact with freshwater contaminated by schistosome cerceriae. Communities in which the infection is most endemic have limited access to clean water and healt...hcare services. Up to 150 million adolescent girls and women are estimated to be at risk of FGS and about 16–56 milion womens are living with FGS, with the majority of these in sub-Saharan Africa. The variability of these estimates points to the fact that this neglected tropical disease is not well studied and frequently not prioritized by local, regional, and global health policy makers.

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

The development of this target product profile (TPP) was led by the WHO Department of Control of Ne-
glected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to
identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG)
was... formed, and different subgroups were created to advise on specific NTDs, including a subgroup
working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of in-
dependent experts included leading scientists, public health officials and endemic-country end-user rep-
resentatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of
the available products and of the development pipeline was conducted, and the salient areas with unmet
needs were identified

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.

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 resea...rch 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 (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the
South of the United States. It is an important cause of early mortality and morbidity, and it is associated with poverty and stigma. A third of
the cases evolve into chronic... cardiomyopathy and gastrointestinal disease. The infection is transmitted vertically and by blood/organ
donation and can reactivate with immunosuppression. Case identification requires awareness and screening programmes targeting the
population at risk (women in reproductive age, donors, immunocompromised patients). Treatment with benznidazole or nifurtimox is most
effective in the acute phase and prevents progression to chronic phase when given to children. Treating women antenatally reduces but does
not eliminate vertical transmission. Treatment is poorly tolerated, contraindicated during pregnancy, and has little effect modifying the
disease in the chronic phase. Screening is easily performed with serology. Migration has brought the disease outside of the endemic
countries, where the transmission continues vertically and via blood and tissue/organ donations. There are more than 32 million migrants
from Latin America living in non-endemic countries. However, the infection is massively underdiagnosed in this setting due to the lack of
awareness by patients, health authorities and professionals. Blood and tissue donation screening policies have significantly reduced
transmission in endemic countries but are not universally established in the non-endemic setting. Antenatal screening is not commonly
done. Other challenges include difficulties accessing and retaining patients in the healthcare system and lack of specific funding for the
interventions. Any strategy must be accompanied by education and awareness campaigns directed to patients, professionals and policy
makers. The involvement of patients and their communities is central and key for success and must be sought early and actively. This review
proposes strategies to address challenges faced by non-endemic countries
