HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

The key to a lasting world free of all forms of poliovirus lies in rapidly interrupting all remaining endemic transmission of WPV in the endemic areas of Pakistan and Afghanistan. This is the only way to ensure that such strains do not re-emerge globally through international spread. It lays the cor...nerstone for the eventual cessation of all oral polio vaccine use, in order to eliminate the long-term risks associated with variant poliovirus strains, which is the GPEI’s top operational priority. The target for certifying the
world free of all WPV remains end-2026.

At the end of 2023, WHO convened our first-ever annual WHO Stakeholder Review Conference for Prevention and Response to Sexual Misconduct. Aimed at joint learning and frank discussion on challenges faced in the achieving zero tolerance for all forms of sexual misconduct by aid workers, the Conferenc...e brought together Member States, Civil Society Organizations, United Nations Agencies and Programmes, academia and media joined by WHO personnel. A set of recommendations to support all agencies are documented in the Conference Report. In addition, WHO’s Director-General hosted a social engagement segment on the evening of Day 1 to further underscore the centrality of a victim and survivor-centred approach, to celebrate progress however small, and to reaffirm commitment and renew energy for the journey ahead. The Conference took place on 30 November and 1 December 2023 in Geneva, Switzerland

A sanitary inspection is a simple, on-site evaluation (traditionally using a checklist) to help identify and support the management of priority risk factors that may lead to contamination of a drinking-water supply. Sanitary inspections are a well-established and widely-applied practice. They can su...pport water safety planning, and in some contexts, may be a simplified alternative to water safety plans.
This publication presents the World Health Organization’s (WHO’s) sanitary inspection packages. These packages update the sanitary inspection forms in WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. With more than 25 years of practical experience with the application of sanitary inspections, these packages have been developed from a comprehensive evidence review and established good practices.

This action plan is intended for senior-level decision-makers in ministries of health, malaria
programme managers, entomologists, and epidemiologists working on malaria and other vectorborne diseases programmes. It is also intended for decision-makers and technical and advocacy
staff at other orga...nizations and stakeholders involved in public health, malaria control and
elimination, and urban and rural development.

At its 48th session of Codex Committee on Food Hygiene (CCFH), the Committee noted the importance of water quality and safety in food production and processing. CCFH requested the Food and Agriculture Organization of the United Nations
(FAO) and the World Health Organization (WHO) to provide guidan...ce for those scenarios where the use of “clean water” (i.e. water that does not compromise the safety of the food in the context of its use) was indicated in Codex texts and on
where it is appropriate to use “clean water”. In particular, guidance was sought for the use of irrigation water and “clean” seawater and on the safe reuse of processing water.

Driving progress towards rabies elimination: Results of Gavi’s Learning Agenda on rabies and new WHO position on rabies immunization
The objectives of the meeting were:
1. To update the current status of the disease transmission, country capacities and plans for tackling the disease.
2. To understand the epidemiology including disease distribution and risk, the models
for estimating under-detection, the geographical variati...ons of in clinical presentation,
the roles of domestic and wild animal reservoirs and the subsequent different
transmission patterns and control approaches, including vector control.
3. To update current research and development efforts for improving diagnostic and
treatment tools.
4. To define the goals for achieving the control of r-HAT, the need for a multisectoral
approach and to discuss the strategy for controlling r-HAT and the coordination
mechanisms.

This Tailoring Antimicrobial Resistance Programmes (TAP) process assists Member States in initiating and undertaking projects to address the spread of antimicrobial resistance (AMR) in their countries. AMR is a complex problem requiring unique, context-specific solutions. This TAP Toolbo...x contains a series of exercises and is aligned with the stages outlined in the TAP Quick Guide. The Toolbox is designed to be used by a TAP working group as they work through the stages outlined in the TAP Quick Guide. The exercises and tools presented in this Toolbox have been abridged and adapted from the TAP Manual which will be available soon.

Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the World... Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.

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.

Weekly Epidemiological Record No 9, 2022, 97, 61–80
This position paper supersedes the 2016 publication, “Malaria vaccine: WHO position paper-2016.”1 It includes the updated WHO recommendations on the wider use of the RTS,S/AS01 vaccine for the reduction of malaria morbidity and mortality in ...children living in areas of moderate to high malaria transmission. It also incorporates findings from the evaluation of the WHO-coordinated Malaria Vaccine Implementation Programme (MVIP), recommended by SAGE and MPAG in 2015, and from additional studies since 2015.
This paper does not include findings on vaccine efficacy in infants first vaccinated at 6–12 weeks of age. Because of the lower vaccine efficacy observed in this age category, WHO did not recommend pilot implementation or RTS,S/AS01 vaccine introduction for these young infants. Recommendations2 on the use of RTS,S/AS01 vaccine were discussed by SAGE and MPAG during a joint session in October 2021; evidence presented at the meeting can be accessed at https://terrance.who.int/mediacentre/data/ sage/SAGE_eYB_Oct2021.pdf
