There are 4 main forms of the disease: visceral leishmaniasis (VL, also known as kala-azar); post-kala-azar dermal leishmania...sis (PKDL); cutaneous leishmaniasis (CL); and mucocutaneous leishmaniasis (MCL). While cutaneous leishmaniasis is the most common form of the disease, visceral leishmaniasis is the most serious and can be fatal if untreated. Additionally, leishmaniasis can be classified as anthroponotic or zoonotic depending on whether the natural reservoir of the parasite is human or animal.
This report updates global epidemiological information on VL and CL to 2015, based on the main indicators published in the GHO, as of 1st September 2017.

4th edition
The WHO Laboratory Biosafety Manual (LBM) has been in broad use at all levels of clinical and public health laboratories, and other biomedical sectors globally, serving as a de facto global standard that presents best practices and sets trends in biosafety.
LBM encouraged countries t...o accept and implement basic concepts in biological safety and to develop national codes of practice for the safe handling of biological agents in laboratories within their geographical borders.
This fourth edition of the manual builds on the risk assessment framework introduced in the third edition. A thorough, evidence-based and transparent assessment of the risks allows safety measures to be balanced with the actual risk of working with biological agents on a case-by-case basis.
This novel evidence- and risk-based approach will allow optimised resource use and sustainable laboratory biosafety and biosecurity policies and practices that are relevant to their individual circumstances and priorities, enabling equitable access to clinical and public health laboratory tests and biomedical research opportunities without compromising safety.

Despite being a curable and preventable disease, tuberculosis (TB) remains as one of the major challenges for health systems, globally. Every year, TB affects more than 10 million people and kills more than 1.4 million people. WHO’s Digital Health for the End TB Strategy – an Agenda for Action o...utlines a conceptual framework in which advantageously positioned digital health solutions are matched to the most urgent needs of TB programmes. Video-supported treatment is a component of one of the four core functions of this framework, the Patient Care domain, and primarily supports the first pillar of the End TB Strategy. This quick guide provides information on the solutions available for asynchronous modes of video communication and how these can be of use to TB programmes.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

When situations occur in which unwanted events are rightly or wrongly connected with vaccination, they may erode confidence in vaccines and the authorities delivering them. This document presents the scientific evidence behind WHO’s recommendations on building and restoring confidence in vaccines ...and vaccination, both in ongoing work and during crises. The evidence draws on a vast reserve of laboratory research and fieldwork within psychology and communication. It examines how people make decisions about vaccination; why some people are hesitant about vaccination; and the factors that drive a crisis, covering how building trust, listening to and understanding people, building relations, communicating risk and shaping messages to the audiences may mitigate crises. This document provides a knowledge base for stakeholders who develop communication strategies or facilitate workshops on communication and trust-building activities in relation to vaccines and immunization, such as immunization programme units, ministries of health, public relations and health promotion units, vaccine safety communication trainers and immunization advisory bodies.

The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

In 2015 around 15 million people living with HIV were receiving antiretroviral treatment (ART) in sub–Saharan Africa. Sustained provision of ART, though both prudent and necessary, creates substantial long–term fiscal obligations for countries affected by HIV/ AIDS. As donor assistance for healt...h remains constrained, novel financing mechanisms are needed to augment funding domestic sources. We explore how Innovative Financing has been used to co–finance domestic HIV/AIDS responses. Based on analysis of non–health sectors, we identify innovative financing instruments that could be used in the HIV response.
