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.

The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people ...living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5–15% of AIDS-related deaths every year in this Region. These guidelines aim to provide recommendations for the diagnosis, treatment, and management of disseminated histoplasmosis in persons living with HIV

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.

Sequencing enabled the world to rapidly identify SARS-CoV-2 and develop diagnostic tests and other tools for outbreak management. Continued genome sequencing supports the monitoring of the disease’s spread and evolution of the virus. Accelerated integration of genome sequencing int...o the practices of the global health community is required if we want to be better prepared for the future threats. This document provides guidance for laboratories on maximizing the impact of SARS-CoV-2 sequencing now and other emerging pathogens in the future.
