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.

Historically, the discovery of the sulfa drugs in the 1930s and the subsequent development of penicillin during World War II ushered in a new era in the treatment of infectious diseases. Infections that were common causes of death and disease in the pre-...antibiotic era - rheumatic fever, syphilis, cellulitis and bacterial pneumonia - became treatable, and over the next 20 years most of the classes of antibiotics that find clinical use today were discovered and changed medicine in a profound way. The availability of antibiotics enabled revolutionary medical interventions such as cancer chemotherapy, organ transplants and essentially all major invasive surgeries from joint replacements to coronary bypass. Antibiotics, though, are unique among drugs in that their use precipitates their obsolescence. Paradoxically, these cures select for organisms that can evade them, fueling an arms race between microbes, clinicians and drug discoverers.

The second edition of the WHPCA Global Atlas of Palliative Care was launched during World Hospice & Palliative Care Day 10 October. The Atlas is an update of the original WHPCA/WHO Global Atlas of Palliative care at the end of life published in 2014. It is full of useful facts and figures to support... palliative care advocacy and development. In this edition we have switched from using the WHO methodology for need for palliative care to the evolving Lancet Commission on Palliative Care and Pain Relief methodology. As a result the number of people needing palliative care has gone from 40 million per year to almost 57 million and more accurately reflects the need for palliative care globally models of palliative care worldwide? What resources are devoted to palliative care? What is the way forward?

The current document is anupdate of the guidelines developed by the EUCAST subcommittee on detection of resistance mechanisms. The EUCAST Steering Committee has carried out the current update. The document has been developed mainly for routine use in clinical laboratories and doesnot cover technical... procedures for identification of resistance mechanisms at a molecular level by reference or expert laboratories. However, much of the content is also applicable tonational reference laboratories. Furthermore, it is important to note that the document does not cover screening for asymptomatic carriage (colonization) of multidrug-resistant microorganismsor direct detectionof resistancein clinical samples.

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st century. The situation is deteriorating in many countries, particularly because of the synergy with t...he HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

Tsetse traps and targets (insecticide-impregnated screens) function by attracting the flies to a device that collects and/or kills them. Traps can be used for entomological surveillance, and also for control. Targets are simpler than traps, but are not used for surveillance. They are impregnated wit...h biodegradable insecticides in order to kill any flies that alight on them. Traps can also be impregnated with insecticides. Traps and targets can both be used to eliminate a fraction of the tsetse population.

Las directrices terapéuticas descritas en este documento pueden aplicarse no sólo en los hospitales, sino también en centros de alimentación terapéutica en situaciones de emergencia y en centros de nutrición para rehabilitación tras el tratamiento inicial en un hospital. [OMS]
This guidance addresses rationale, risk-based scenarios, practical considerations prior to adoption of the self-testing products, quality assurance, safety and ethical considerations, and data management considerations for COVID-19 self-testing. The Africa CDC recommends the use of rapid antigen sel...f-testing within two key scenarios. The first includes testing for case identification within scenarios with a high risk of infection, including symptomatic cases and contacts of a confirmed case. The second scenario involves general screening within scenarios of low or unknown risk exposure allowing for self-care such as before gatherings with at-risk individuals and prior to participation in events involving members of different households. Within these scenarios, a positive test result indicates likelihood of current infection, while a negative test result indicates a lower risk of active infection, though it does not rule out infection altogether. All positive cases should be managed following the national COVID-19 management protocol of Member States.ssur

Rapid Recommendation and visual graph. This is the fifth version (update 4) of the living guideline (BMJ 2020;370:m3379). When citing this article, please consider adding the update number and date of access for clarity. The publication of the RE...COVERY and REMAP-CAP randomised controlled trials triggered this guideline update, resulting in a strong recommendation for interleukin-6 (IL-6) receptor blockers (tocilizumab or sarilumab) in patients with severe or critical covid-19.
Prior recommendations: (a) A recommendation not to use ivermectin in patients with covid-19, regardless of disease severity, except in the context of a clinical trial; (b) a strong recommendation against the use of hydroxychloroquine in patients with covid-19, regardless of disease severity; (c) a strong recommendation against the use of lopinavir-ritonavir in patients with covid-19, regardless of disease severity; (d) a strong recommendation for systemic corticosteroids in patients with severe and critical covid-19; (e) a conditional recommendation against systemic corticosteroids in patients with non-severe covid-19; and (f) a conditional recommendation against remdesivir in hospitalised patients with covid-19.

Risk Communication and Community Engagement (RCCE) is an essential part of any disease outbreak response. Risk communication in the context of an Ebola outbreak refers to real time exchange of information, opinion and advice between frontline responders and people who are faced with the threat of Eb...ola to their survival, health, economic or social wellbeing. Community engagement refers to mutual partnership between Ebola response teams and individuals or communities in affected areas, whereby community stakeholders have ownership in controlling the spread of the outbreak.
It is intended to be used to guide RCCE work which is central to stopping the outbreak and preventing its further amplification. Unlike other areas of response, RCCE draws heavily on volunteers, frontline personnel and on people without prior training in this area. As such, the document provides basic background information, scopes the socio-economic and cultural aspects (that are known at the time of publication), and provides the latest evidence-based advice and approaches

“Guide to facilitate the implementation of the WHO/UNICEF “Guidance on developing a national deployment and vaccination plan for COVID-19 vaccines” for Africa
t contains action-oriented lists of critical topics to address and checklists tailored to the context of African Union Member States.
...
The contents of this guide aim to guide the development of one comprehensive national deployment and vaccination plan, as proposed and outlined by the guidance – and underlines the need for countries to develop their vaccination plans.
This guide is not meant as a tool to assess deployment readiness. The recommendation to Member States is to use the VIRAT/VRAF 2.0 tool for that, which builds on the COVAX Vaccine Introduction Readiness Assessment Tool (VIRAT) and the World Bank’s Vaccine Readiness Assessment Framework (VRAF).

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Policy brief, 24 July 2020
The COVID-19 pandemic has affected older people disproportionately, especially those living in long-term care facilities. In many countries, evidence shows that more than 40% of COVID-19 related deaths have been linked to long-term care facilities, with figures being as h...igh as 80% in some high-income countries. Concerted action is needed to mitigate the impact across all aspects of long-term care, including home- and community-based care, given that most users and providers of care are those who are vulnerable to severe COVID-19.
This policy brief provides 11 policy objectives and key action points to prevent and manage COVID-19 across long-term care. Its intended audience is policy makers and authorities (national, subnational and local) involved in the COVID-19 pandemic. The brief builds on currently available evidence on the measures taken to prevent, prepare for and respond to the COVID‑19 pandemic across long-term care services including care providers

The CBDRR Manual is a practical ‘how-to’ guide on community-based disaster risk reduction for government and non-government agencies in Lao PDR. It is a commonly agreed document to be referred to by agencies working on CBDRR in Lao PDR. It provides guidance and support for systematic implementat...ion of CBDRR programs by explaining each of the steps as well as tools used.
The manual will also support the Government of Lao PDR (GoL) to monitor CBDRR activities, oversee progress of activities implemented by different actors and locations, provide necessary support on CBDRR technical knowledge as well as provide a reference point for replication of initiatives for local government and implementing agencies.

Children with disabilities are particularly vulnerable in humanitarian settings, yet they are often not able to access the services and protection they need. While multiple factors create these barriers, a major cause is how data about children with disabilities is collected and mapped. Data collect...ion processes often exclude or underrepresent the views of children with disabilities and thier caretakers. When the experiences of children with disabilities and their caretakers are not defined and collected, they become excluded from mainstreamed protective services, which are meant to serve all children. Children with disabilities also do not get the specialised interventions they need.
This guidance note explores how to use qualitative methods to create more robust assessment processes to ensure more effective programming and services for children with disabilities. This note provides promising practices for engaging with children with disabilities and includes sample tools that can be tailored to fit the needs of a particular assessment process. The note also explores the importance of thoughtful cross-sectoral responses so that children with disabilities, and their families, are carefully considered in areas like water, sanitation, and hygiene (WASH), education, health, and nutrition, and therefore receive the holistic support they need and deserve.
This note is intended for a broad audience of relevant child protection actors, including practitioners, coordination groups, researchers, and donors. The information is not limited to one type of humanitarian setting, geographic region, or culture. As a result, the practices and guidance should be adapted to each specific context, ideally in partnership with well-informed local actors, such as representatives from local organisations for persons with disabilities.

ndependent of the current conflict, the health sector in Ukraine faces several critical shortcomings. In particular, the country has an oversupply of hospitals and an undersupply of primary care and diagnostic facilities. Addressing these limitations will require substantial amounts of capital inves...tment, but constraints on public finances in the post-war context will reduce the Government’s ability to fund the needed reconfiguration. Multiple international financial institutions have stated their intention to support reconstruction in the aftermath of the war. The use of public–private partnerships (PPPs) may support the achievement of these outcomes and their use in Ukraine is likely to remain an important issue for Government policy-makers and their partners to consider in a variety of post-war scenarios.
