The epidemiology of the disease is mediated by the interaction of the parasite (trypanosome) with the vectors (tsetse flies), as well as with the human and animal hosts within a particular environment. Related to these interactions, the disease is c...onfined in spatially limited areas called “foci”, which are located
in Sub-Saharan Africa, mainly in remote rural areas. The risk of contracting HAT is, therefore, determined by the possibility of contact of a human being with an infected tsetse fly. Epidemics of HAT were described at the beginning of the 20th century; intensive activities have been set up to confront the disease, and it was under control in the 1960s, with fewer than 5,000 cases reported in the whole continent.

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.

This analysis focused on the chronic form of HAT caused by T. b. gambiense, as it contributes to the majority of disease burden. Information from the literature review,
product development landscape, and stakeholder interviews was compiled to:
- Identify use cases and understand current diagnosti...c practices and tools associated with each use case.
- Analyze progress toward robust diagnostics for HAT across different biomarkers.
- Develop recommendations for steps to improve the availability, access, and adoption of HAT diagnostic tools.

BACKGROUND: Growing political attention to antimicrobial resistance (AMR) offers a rare opportunity for achieving meaningful action. Many governments have developed national AMR action plans, but most have not yet implemented policy interventions to reduce antimicrobial overuse. A systematic evidenc...e map can support governments in making evidence-informed decisions about implementing programs to reduce AMR, by identifying, describing, and assessing the full range of evaluated government policy options to reduce antimicrobial use in humans.
METHODS AND FINDINGS: Seven databases were searched from inception to January 28, 2019, (MEDLINE, CINAHL, EMBASE, PAIS Index, Cochrane Central Register of Controlled Trials, Web of Science, and PubMed). We identified studies that (1) clearly described a government policy intervention aimed at reducing human antimicrobial use, and (2) applied a quantitative design to measure the impact. We found 69 unique evaluations of government policy interventions carried out across 4 of the 6 WHO regions. These evaluations included randomized controlled trials (n = 4), non-randomized controlled trials (n = 3), controlled before-and-after designs (n = 7), interrupted time series designs (n = 25), uncontrolled before-and-after designs (n = 18), descriptive designs (n = 10), and cohort designs (n = 2). From these we identified 17 unique policy options for governments to reduce the human use of antimicrobials. Many studies evaluated public awareness campaigns (n = 17) and antimicrobial guidelines (n = 13); however, others offered different policy options such as professional regulation, restricted reimbursement, pay for performance, and prescription requirements. Identifying these policies can inform the development of future policies and evaluations in different contexts and health systems. Limitations of our study include the possible omission of unpublished initiatives, and that policies not evaluated with respect to antimicrobial use have not been captured in this review.
CONCLUSIONS: To our knowledge this is the first study to provide policy makers with synthesized evidence on specific government policy interventions addressing AMR. In the future, governments should ensure that AMR policy interventions are evaluated using rigorous study designs and that study results are published.

The main purpose of the meeting was to review tsetse control tools, activities and their contribution to the elimination of gHAT and the monitoring thereof. Seven endemic countries provided reports on recent and ongoing vector control interventions at the national level (Angola, Cameroon, Côte d’...Ivoire, Chad, Democratic Republic of the Congo, Guinea and Uganda). Country reports focused on the in situations implementing and supporting vector control activities, the tools and the approaches in use, the coverage of the activities in space and time and their impacts on tsetse populations. Future perspectives for vector control in the respective countries were also discussed, including opportunities and challenges to sustainability.

Rabies remains an under-reported neglected zoonosis with a case-fatality rate of almost 100% in humans and animals. Dog-mediated human rabies causes tens of thousands of human deaths annually despit...e being 100% preventable. More than 95% of human cases are caused by the bite of a rabies-infected dog. Dog-mediated human rabies disproportionately affects rural communities, particularly children, and economically disadvantaged areas of Africa and Asia, where awareness of the disease and access to appropriate post-exposure prophylaxis (PEP) can be limited or nonexistent.

Through technical consultations with countries and partners, WHO has led the development of Preparedness and Resilience for Emerging Threats Module 1: Planning for respiratory pathogen pandemics. Version 1.0. The Module, currently available as an ad...vanced draft, builds on previous pandemic lessons and guidance, and has the following new elements:
It presents an integrated and efficient respiratory pathogen pandemic planning approach covering both novel pathogens and those known to have pandemic potential;
It enables coherence in addressing pathogen-agnostic and pathogen-specific elements for better preparedness;
It gives an organizing framework including operational stages and triggers for escalation and de-escalation between pandemic preparedness and response periods;
It contextualizes 12 IHR (2005) core capacities within the five components of health emergency preparedness, response and resilience (HEPR), from the respiratory threats perspective; and
It describes the critical sectors for respiratory pathogen pandemic preparedness to trigger multisectoral collaboration.
WHO will finalize and publish this Module after a global technical meeting that will be held on 24-26 April 2023.

Antimicrobial resistance (AMR) is an increasing worldwide public health problem with
important implications for the European Union (EU). When antibiotics become
ineffective, bacterial infections lead to increased morbidity, use of healthcare,
mortality and cost. Globally, estimates suggest that ...AMR leads to 700 000 deaths
per annum. For the EU, the European Centre for Disease Prevention and Control
(ECDC) has estimated that AMR currently causes 25 000 deaths annually and losses of
at least EUR 1.5 billion per annum in extra healthcare costs and productivity.

Wet markets have been implicated in multiple zoonotic outbreaks, including COVID-19. They are also a conduit for legal and illegal trade in wildlife, which threatens thousands of species. Yet wet markets supply food to millions of people around the world, and differ drastically in their physical com...position, the goods they sell, and the subsequent risks they pose. As such, policy makers need to know how to target their actions to efficiently safeguard human health and biodiversity without depriving people of ready access to food.

Following the publication of Guidelines on certification of elimination of human onchocerciasis in 2001 by the World Health Organization (WHO), these are the first evidence-based guidelines developed by NTD Department according to the international ...standards. They provide a set of recommendations that would guide national programme managers in collaboration with their respective oversight committees on when to stop mass drug administration (MDA) and conduct post-treatment surveillance (PTS) activities for a minimum period of 3 to 5 year before confirming the interruption of transmission of Onchocerca volvulus parasite and hence its elimination. They also include steps to undertake for verification of elimination of transmission of the parasite in the whole endemic country by the International Verification Team (IVT) prior to the official acknowledgement by WHO Director General.
