This report compiles data for the first time on the far-reaching consequences of uncontrolled hypertension, including heart attacks, strokes and premature death, along with substantial economic losses for communities and countries. It also contains information on the global, regional and country-lev...el burden of hypertension and progress of control efforts.

A total of 18 laboratories from 13 countries participated in the four rounds of EQA: 10 laboratories from eight African endemic countries, four of which participated in all four rounds and three in three rounds. The overall results showed that the median performance of these laboratories improved ov...er the four rounds. However, the proportion of laboratories reporting false–positive cases remains high and indicates a problem of specificity probably due to contamination. The proportion of laboratories reporting both false–positive and false–negative results raises the issue of the quality of the data reported by WHO in Africa as well as the results of the studies carried out in these different laboratories in various countries.

About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance.

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

Following review of the latest evidence, WHO recommends that TB-LAMP can be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. It can also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, e...specially when further testing of sputum smear-negative specimens is necessary.

The aim of the operational framework is to ensure 1) accurate collection, handling, shipment and storage of specimens collected in countries implementing HIV drug resistance surveillance; and 2) the availability of quality-assured HIV genotyping laboratory services producing comparable and reliable ...results at the national, regional and global levels.
This publication updates the WHO HIVResNet HIV drug resistance laboratory operational framework published in 2017 and reflects technical and strategic developments over the past three years.

A manual for impact assessments. The SCH Practical and Precision Assessment (SPPA) strategy is an evidence-based approach for conducting impact assessments for SCH. The SPPA was identified by programme managers and SCH experts from the African region as a feasible and sufficiently accurate approach ...after reviewing and discussing the results of a multi-country study. This manual describes the resulting Practical and Precision Assessments approach and includes a discussion of the underlying concepts, factors to consider when determining what approach is appropriate, and how to interpret the collected data. The manual also includes annexes with standard operating procedures for conducting the stool and urine analyses.
