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.

The technical note from the Global Task Force on Cholera Control (GTFCC) examines the risks and benefits of vaccinating pregnant women with WHO-prequalified oral cholera vaccines (OCVs) during mass vaccination campaigns. It highlights that three WHO-approved vaccines (Dukoral®, Shanchol™, and Euv...ichol®) offer sustained protection and a strong safety profile.
While these vaccines are not explicitly contraindicated for pregnant women, there is limited clinical data on their use during pregnancy. However, studies indicate that pregnant women with cholera face higher risks of fetal loss, stillbirth, and complications, especially if they experience severe dehydration. Some evidence suggests that vaccination can reduce cholera incidence in pregnant women and indirectly protect infants.
Although no controlled trials have focused on pregnant women, retrospective studies in Guinea and Zanzibar showed no significant increase in adverse pregnancy outcomes after OCV administration. The GTFCC concludes that the benefits of vaccination outweigh the risks, particularly in high-risk areas, and recommends including pregnant women in cholera vaccination campaigns while continuing to monitor safety data.

External quality assessment (EQA) is an important component of quality systems for blood transfusion services. Establishing external quality assessment programmes for screening of donated blood for transfusion-transmissible infections (TTI): implementation guide aims to support WHO member States in ...establishing and operating EQA programmes for screening donated blood for TTI. The guides has been designed for use by national health authorities and EQA organizing institutions in the development of EQA programme. It will also give participating laboratories an insight into the organization of EQA programmes for TTI screening and an understanding of the benefits of participation.

The ongoing COVID-19 pandemic presents an exceptional and unprecedented challenge for competent authoritiesa with responsibilities for national food safety control systemsb to continue conducting routine functions and activities in accordance with national regulations... and international recommendations. In many countries, competent authority staff are largely working from home, teleworking being the normal practice, and all face-to-face meetings cancelled or rescheduled as teleconferences. It is challenging to maintain, without interruption, routine activities such as the inspection of food business operations, certifying exports, control of imported foods, monitoring and surveillance of the safety of the food supply chain, sampling and analysis of food, managing food incidents, providing advice on food safety and food regulations for the food industry, and communicating on food safety issues with the public.

These guidelines provide updated evidence-based recommendations on the priority HCV-related topics from the 2018 WHO Guidelines for the care and treatment of persons diagnosed with chronic hepatitis C infection and the 2017 WHO Guidelines on hepatitis B and C testing. These priority areas are:
... direct-acting antiviral (DAA) treatment of adolescents and children ages ≥3 years of age
simplified HCV service delivery (decentralization, integration and task sharing)
HCV diagnostics – use of point-of-care (POC) HCV ribonucleic acid (RNA) assays and reflex HCV RNA testing.
These guidelines also update existing chapters without new recommendations, such as the inclusion of new manufacturers’ protocols on the use of dried blood spot (DBS) for HCV RNA testing and new data to inform the limit of detection for HCV RNA assays as a test of cure, in addition to their use for diagnosis.

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.
