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 envenoming is a neglected tropical disease (NTD) that is responsible for enormous suffering, disability and premature death on every continent. As over 5.8 billion people are at risk of encountering a venomous snake, it is not surprising but no less tragic that almost 7400 people every
da...y are bitten by snakes, and 220–380 men, women and children die as a result, adding up to about 2.7 million cases of envenoming and 8100–138 000 deaths a year.

Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by venom being sprayed into a person’s eyes by certain species of snakes tha...t have the ability to spit venom as a defence measure. Not all snakebites result in envenoming: some snakes are non-venomous and venomous snakes do not always inject venom during a bite. About 50–55% of all snakebites result in envenoming. Snake venoms are complex mixtures of protein and peptide toxins, varying from one species to another, and even within species. The toxins in snake venoms are evolutionarily adapted to interact with a large variety of cellular targets in the organisms exposed to them. In humans and animals, snakebite envenoming affects multiple organ systems (depending on the particular species of snake and the classes of toxins present in the venom) and can cause, among other things: haemorrhage and prolonged disruption of haemostasis, neuromuscular paralysis, tissue necrosis, myolysis (muscle degeneration), cardiotoxicity, acute kidney injury, thrombosis and hypovolaemic shock.

Yaws is targeted for eradication by 2030, using a strategy based on mass drug administration (MDA) with azithromycin. New diagnostics are needed to aid eradication. Serology is currently the mainstay for yaws diagnosis; however, inaccuracies associated with current serological tests makes it difficu...lt to fully assess the need for and impact of eradication campaigns using these tools. Under the recommendation of the WHO Diagnostic Technical Advisory Group (DTAG) for Neglected Tropical Diseases(NTDs), a working group was assembled and tasked with agreeing on priority use cases for developing target product profiles (TPPs) for new diagnostics tools.

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.

American trypanosomiasis, commonly called
Chagas disease (CD), was prevalent once in rural areas
of Latin America where poverty is widespread and was
considered a silent and poorly visible disease. It
has become a global neglected tropical disease and a
significant public health th...reat worldwide due to
globalization over last century. More recently, it has
attracted much more attention, and “April 14” has
been designated as “World Chagas Disease Day” by
the World Health Assembly of 2019 to raise
awareness of the disease as a neglected tropical disease,
to improve the rates of early treatment and recovery,
and to achieve the ambitious goal to interrupt its
transmission.

Trachoma, caused by particular serovars of Chlamydia trachomatis, is the leading
infectious cause of blindness. Infection is transmitted within ocular and nasal secretions that are passed from person to person on fingers, fomites (such as clothing) and eye-seeking flies (particularly Musca sorbens)....
Ophthalmic infection is associated with an inflammatory conjunctivitis known as “active trachoma”. Repeated episodes of active trachoma can scar the eyelids. In some individuals this leads to trachomatous trichiasis (TT), in which one or more eyelashes on the upper
eyelid touch the eye. TT is extremely painful. It can be corrected surgically, but, if left untreated, may lead to corneal opacification, resulting in vision impairment and blindness.

This study shows the importance of an integrated entomological and medical surveillance for the evaluation of arboviral disease risk, which is a precondition for designing cost-effective vector control programs.

Этот подход включает в себя перемещение лиц, совершающих поездки, и багажа, грузов, контейнеров, перевозочных средств, товаров и почтовых посылок через наземные переходы, а также взаимодействие с соседними пограничными сообществами. При необходимости в ходе оценки риска могут учитываться и другие факторы.

Front. Med., 27 November 2020 | https://doi.org/10.3389/fmed.2020.594728. The Checklist included eight actions for implementing rural pathways in LMICs: establishing community needs; policies and partners; exploring existing workers and scope; selecting health workers; education and training; workin...g conditions for recruitment and retention; accreditation and recognition of workers; professional support/up-skilling and; monitoring and evaluation. For each action, a summary of LMICs-specific evidence and prompts was developed to stimulate reflection and learning. To support implementation, rural pathways exemplars from different WHO regions were also compiled. Field-testing showed the Checklist is fit for purpose to guide holistic planning and benchmarking of rural pathways, irrespective of LMICs, stakeholder, or health worker type.

Hесмотря на многочисленные международные договоры и обязательства по защите прав мигрантов в области здравоохранения, эта ключевая затронутая группа населения п... прежнему испытывает серьезные затруднения в доступе к лечению от туберкулеза. Миграция вызвана рядом сложных экономических, социальных, политических и экологических факторов и является определяющим элементом плохого здоровья, а результаты лечения мигрантов находятся под воздействием различных измерений миграционного процесса.
