Most neglected tropical diseases (NTDs) occur in remote areas of low- and middle-income countries, where health systems are often poorly developed. Therefore, these neglected patients generally lack access to quality preventive, diagnostic, and therapeutic care [1]. The difficulty to access NTD-ende...mic areas, challenging logistics, and the lack of skilled human resources in these areas are also major obstacles to conduct clinical research. We had to face these when conducting a good clinical practice/good clinical laboratory practice (GCP/GCLP)-compliant clinical study in eastern Sudan, a well-known endemic area for visceral leishmaniasis and other NTDs. We share here the challenges related to study preparation and implementation of this GCP/GCLP study that investigated the causes of persistent fever in a rural hospital located in Gedaref State in eastern Sudan. We think this type of paper may be of interest for researchers planning to conduct a clinical trial in a resource-limited setting as well as for funders of such research.

Snakebite is an acute life threatening time limiting medical emergency. It is a preventable public
health hazard often faced by rural population in tropical and subtropical countries with heavy
rainfall and humid climate.
Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally kn...own as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.

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 b...e added 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.

Rabies is fatal, vaccine-preventable disease responsible for an estimated 59,000 human deaths each year. Most cases are transmitted by dogs, and most deaths occur in underserved populations in Africa and Asia. Approximately 40% of deaths occur in children.
Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

Leishmaniases are a group of diseases of zoonotic importance caused by over 20 species of protozoa of the genus Leishmania, in which domestic dogs are considered to be the main reservoir for the disease. However, the involvement of other vertebrates as reservoirs for these parasites has also been in...vestigated. Therefore, the objective of the present study was to carry out a systematic review with meta-analysis on occurrences of leishmaniasis in equids. The case reports described animals with cutaneous symptoms of leishmaniasis (papules, nodules, ulcers or crusts) that regressed spontaneously, located mainly on the head and limbs, from which three species of protozoa were identified in the lesions: Leishmania braziliensis, Leishmania infantum and Leishmania siamensis. In turn, the meta-analysis showed a combined prevalence of 25%, although with high heterogeneity among the studies, which was attributed to the use of different methods for diagnosing the disease. Leishmaniasis in equids is a benign disease but it should be included in the differential diagnosis of cutaneous diseases among these species. Seroepidemiological studies are important in investigating and monitoring suspected exposure of these hosts to the parasite, especially in endemic areas. However, there is also a need to standardize diagnostic methods.

Nosocomial or health-facility-acquired infections are a serious issue, representing one of the most significant causes of morbidity and mortality in healthcare systems and consuming many scarce resources, especially in developing countries. Although much has been done, particularly in the hospital s...etting, to reduce the risk of these infections, the problem persists and demands innovative and cost-efficient solutions.
Although the care provided in most primary health care facilities is predominantly ambulatory with few or no inpatient beds, infection prevention is still important to minimize or eliminate the risks of facility-acquired infections and assure quality patient care.
Health facilities and hospitals should have written infection control procedures and guidelines in place and should also be monitoring that these procedures are adhered to in both inpatient and ambulatory care settings.

Health care-associated infection (HCAI) places a serious disease burden and has a significant economic impact on patients and health-care systems throughout the world. Yet good hand hygiene, the simple task of cleaning hands at the right times and in the right way, can save lives. World Health O...rganization (WHO) has developed evidence-based WHO Guidelines on Hand Hygiene in Health Care to support health-care facilities to improve hand hygiene and thus reduce HCAI.

Antimicrobial agents play an indispensable role in animal health and welfare management. At the same time, the need for prudent use is obvious to ensure good food safety outcomes and to manage the potential risk of antimicrobial resistance. The emergence of multi-resistant bacteria is posing challen...ges to health professionals and communities around the world for both human and animal health. These bacteria are not destroyed by the common antimicrobial agents and so pose a risk to people, particularly children, the elderly and those with poorly functioning immune systems, as well as to animals.
Throughout the years, the dairy sector has been very much aware of the need for responsible use and has, in many countries, implemented adequate measures throughout the dairy supply chain.

A group of enzootic and zoonotic protozoan infections, the leishmaniases constitute among the most severely neglected tropical diseases (NTDs) and are found in all continents except Oceania. Representing the most common infectious diseases, NTDs comprise an open-ended list of some 20 parasitic, bact...erial, viral, protozoan and helminthic infections. Called “diseases of the poor,” because of their characteristic prevalence in poor populations regardless of a country's income status, they infect over one billion people in over 140 countries, with about 90% of the global burden in Africa. While NTDs do not contribute significantly to global deaths, they are debilitating and remain the most common infections among the poor worldwide, preventing them from escaping poverty by impacting livelihoods such as agriculture and livestock, and affecting cognitive, developmental and education outcomes.

More than 700 000 people lose their life to suicide every year. A core foundation of suicide prevention is the timely registration and regular monitoring of suicide and self-harm. Surveillance data can be used to show important progress towards reaching global targets, such as reducing the suicide r...ate by one third by 2030 as articulated in the UN SDGs and in the WHO Mental Health Action Plan 2013-2030. However, there are considerable discrepancies in the quality of data on suicide and self-harm globally. The aim of this training manual is to equip fieldworkers and supervisors with the skills to collect and manage data on suicide and self-harm in the community via key informants, health-care facilities and police records. In doing so, the value and overall goal is to strengthen the surveillance of suicide and self-harm in communities, particularly in LMICs and hard-to-reach communities where CRVS systems are weak or absent.

A study set out to investigate the factors affecting the prevalence of the practice among cross-border communities in East Africa and the Horn of Africa and the extent to which people cross borders to practise or undergo FGM and the effects of the practice on the women and girls in those communities.... Changes were found in social norms in the cross-border communities investigated, indicating that the practice of female genital mutilation (FGM) can be eradicated. Effective interventions to end FGM need to be tailored to communities’ belief systems if they are to be “owned” by and mobilize the communities to change their culture. This report summarises the findings.

Today, patient harm due to unsafe care is a large and growing global public health challenge and is one of the
leading causes of death and disability worldwide. Most of this patient harm is avoidable. As countries strive to
achieve universal health coverage and the Sustainable Development Goals, t...he beneficial effects of improved
access to health services can be undermined by unsafe care. Patient safety incidents can cause death and
disability, and suffering for victims and their families. The financial and economic costs of safety lapses are high.
There is often reduced public confidence and trust in local health systems when such incidents are publicized.
Health workers involved in serious incidents involving death or serious harm to a patient can also suffer lasting
psychological harm and deep-seated feelings of guilt and self-criticism.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).
