Schistosomiasis is a helminthic infection and one of the neglected tropical diseases (NTDs). It is caused by blood flukes of the genus Schistosoma. It is an important public health problem, particularly in poverty-stricken areas, especially those within the tropics and subtropics. It is estimated th...at at least 236 million people worldwide are infected, 90% of them in sub-Saharan Africa, and that this disease causes approximately 300,000 deaths annually. The clinical manifestations are varied and affect practically all organs. There are substantial differences in the clinical presentation, depending on the phase and clinical form of schistosomiasis in which it occurs. Schistosomiasis can remain undiagnosed for a long period of time, with secondary clinical lesion. Here, we review the clinical profile of schistosomiasis. This information may aid in the development of more efficacious treatments and improved disease prognosis.

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.

In support of the London Declaration goals, PATH aims to catalyze engagement of the diagnostics industry and product development efforts. As part of this work, PATH conducted a diagnostic landscape analysis to identify gaps and evaluated current and nascent HAT diagnostics that may provide solutions....
We conducted literature reviews and interviews with key stakeholders to identify use cases for HAT diagnostics, understand current practices, and analyze progress toward more robust diagnostics across
different biomarkers.

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

A clear understanding of the knowledge, attitudes and practices (KAP) of a particular community is necessary in order to improve control of human African trypanosomiasis (HAT).New screening and diagnostic tools and strategies were introduced into South Sudan, as part of integrated delivery of primar...y healthcare. Knowledge and awareness on HAT, its new/improved screening and diagnostic tools, the places and processes of getting a confirmatory diagnosis and treatment are crucial to the success of this strategy.

Leishmaniasis is a climate-sensitive disease. Changes in temperature, rainfall, and humidity can have strong impacts on
the sandfly vector, altering their distribution and influencing their survival and population sizes. Increased temperatures shorten vector development time, reduce Leishmania para...site incubation time, and increase vector biting rates, allowing transmission
in areas not previously endemic for the disease. Poor and
marginalized communities will be hit disproportionately harder by
the effects of climate change, and droughts, famines, and floods
can also lead to displacement and migration of immunologically
naive people to areas where leishmaniasis is endemic, posing a
threat of leishmaniasis outbreaks.

Symptoms include the onset of acute diarrhea and/or vomiting, muscle cramps, and body weakness. If untreated, the infection can result in rapid dehydration and ...death within hours.

Since 2000, concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypan...osomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on neglected tropical diseases, adopted in 2013.
National sleeping sickness control programmes (NSSCPs) are core to progressing control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for the achievements.

Un comité OMS d’experts sur la trypanosomiase humaine africaine (THA) : lutte et surveillance, s’est réuni à Genève (Suisse), du 22 au 26 avril 2013. Le Dr H. Nakatani, sous-directeur général pour le VIH/SIDA, la tuberculose, le paludisme et les maladies tropicales négligées, a ouvert la... réunion au nom du Dr M. Chan, directeur-général de l’OMS.
La THA est une maladie qui afflige les populations rurales de l’Afrique, là où prolifère la mouche tsé-tsé (ou glossine), vecteur des trypanosomes qui en sont la cause. On distingue deux formes de THA : la forme à T. b. gambiense ou forme gambienne, endémique en Afrique de l’Ouest et en Afrique centrale et qui
représente actuellement 95 % des cas, et la forme à T. b. rhodesiense ou forme rhodésienne, endémique en Afrique de l’Est et en Afrique australe, à laquelle sont dus les 5 % restants.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

Background: The World Health Organization (WHO) published a clinical case definition of post COVID-19
condition, by a Delphi consensus, on 6 October 2021. That process concluded that a separate definition
may be applicable for children. It is important to understand the frequency, characteristics ...and risk factors
that lead to post COVID-19 condition, along with its impact on everyday functioning and development of
children and adolescents. Long-term outcomes of the condition are currently unknown and need to be
studied. For these reasons, a globally standardized clinical case definition is needed.
Aim: To develop a globally relevant standardized clinical case definition for children and adolescents by
building on the WHO clinical case definition for post COVID-19 condition in adults.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.
