This document provides guidance to Ministries of Health (MOHs), laboratory personnel and implementing partners in African Union Member States on the application of rapid antigen tests to COVID-19 testing. The guidance serves as reference for policymakers, laboratory leads, implementing... partners, and experts on use case scenarios and associated testing algorithms for COVID-19 antigen tests. It recommends the use of antigen tests to increase access to testing and enable timely results for persons with or without symptoms in specific settings. The document will be reviewed and updated as more evidence becomes available regarding the use of rapid antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from global studies and evaluation efforts.

In 2019, an estimated 10 million individuals fell ill with tuberculosis (TB) and 3 million of them were not reported to have beendiagnosed and notified. The gap is proportionately even wider for drug-resistant TB. Of the estimated 465 000 patients with rifampicin-resistant and multi-drug resistant T...B (RR/MDR-TB), only 206 030 (44%) were diagnosed and notified.For the first time, the World Health Organization (WHO) has provided global estimates of the incidence of isoniazid resistance: in 2019, there were 1.4 million incident cases of isoniazid-resistant TB, of which 1.1 million were susceptible to rifampicin. Most of these people were not diagnosed with drug-resistant TB and did not receive appropriate treatment.

Scientific brief
8 April 2020
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.

Les procédures décrites dans cette POS concernent à la fois l'environnement dans lequel les tests
index sont effectués (par exemple, la construction d'une infrastructure qui garantit la confidentialité,
les formulaires disponibles sur place, le stockage des données physiques et numériques) ...et
également les actions requises des agents de santé qui effectuent le test index. Les personnes
chargées de la mise en œuvre de ces POS devront également connaître les POS concernant

Au total, 18 laboratoires de 13 pays ont participé aux quatre cycles d'AQE : 10 laboratoires de huit pays africains endémiques, dont quatre ont participé aux quatre cycles et trois à trois cycles. Les résultats globaux ont montré que la performance médiane de ces laboratoires s'est amélioré...e au cours des quatre cycles. Cependant, la proportion de laboratoires rapportant des cas faussement positifs reste élevée et indique un problème de spécificité probablement dû à une contamination. La proportion de laboratoires rapportant à la fois des résultats faussement positifs et faussement négatifs soulève la question de la qualité des données rapportées par l'OMS en Afrique ainsi que des résultats des études menées dans ces différents laboratoires dans divers pays.

March 2025. Access to appropriate, quality-assured diagnostics remains a challenge. There is limited information on key characteristics of available test kits, including their performance, reliability, and ability to detect relevant Mpox clades. Additionally, the lack of multiplex diagnostic tools c...apable of distinguishing Mpox from other pathogens with similar clinical presentations further complicates case detection and response efforts.
