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
l'identification et la réponse face à la violence dans le contexte des tests index. Les recommandations
relatives au contenu des services d'intervention en cas de violence sont fournies en Annexe A

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.

The WHO Cholera Rapid Diagnostic Test (RDT) Target Product Profile outlines the key requirements for developing improved cholera RDTs. It highlights the need for fast, accurate, and easy-to-use tests for early outbreak detection in resource-limited settings. The document sets desired and acceptable ...performance criteria, including high sensitivity and specificity, rapid results (under 15 minutes), and usability by non-laboratory personnel. The tests should be affordable, stable in extreme conditions, and require minimal training. The goal is to enhance cholera surveillance and outbreak response, ensuring quick containment and improved public health outcomes.

On 13 August 2024, Africa Centres for Disease Control and Prevention (Africa CDC) declared the ongoing Mpox outbreak a Public Health Emergency of Continental Security (PHECS). This was followed the next day by the World Health Organization (WHO), which extended the alert internationally as a public ...health emergency of international concern (PHEIC). After these declarations, many countries have made efforts to mobilize resources to introduce or expand laboratory testing, surveillance, and response activities. In particular, as the number of suspected cases surges in the Democratic Republic of Congo (DRC), Burundi, and the Central African Republic, and an increasing number of new countries report cases, there is an urgent need to implement testing to strengthen the Mpox response. However, access to appropriate quality assured diagnostics is a challenge. There is limited information on important characteristics, such as available test kits’ performance and ability to detect relevant clades.
To address the challenge of mpox access in the continent, the Africa CDC Diagnostic Advisory Committee (DAC) met in Kigali from 19-23 August 2024 to review the available evidence on molecular tests for Mpox and to shortlist tests that may be useful for Mpox testing in countries. The shortlist aims to provide guidance to Africa CDC, countries and partners on appropriate high-quality molecular tests to procure and use for the mpox response.

Pneumonia kills more children than any other illness – more than AIDS, malaria and measles combined. Over 2 million children die from pneumonia each year, accounting for almost 1 in 5 under five deaths worldwide. Yet, little attention is paid to this disease. This joint UNICEF/WHO report examines ...the epidemiological evidence on the burden and distribution of pneumonia and assesses current levels of treatment and prevention. It is a call to action to reduce pneumonia mortality, a key step towards the achievement of the millennium development goal on child mortality.

Limited coverage of laboratory services and long turnaround times from real-time reverse transcription-polymerase chain reaction (rRT-PCR) for the detection of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been insufficient to meet the demands in many African countries in response... to the COVID-19 pandemic. Rapid antigen diagnostic tests (AgRDTs) are potentially useful as they can inform healthcare workers and individuals of their infection status at point-of-care testing
