22 July 2022. This document provides the case definitions for public health surveillance of COVID-19 in humans caused by SARS-COV-2 infection.
A Situational Assessment and Five-YearAction Plan for the Africa CDC Strengthening Regional Public Health Institutions and Capacity for Surveillance and Response Program

from COVID-19 disease in comparison with non-pregnant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.

er 46 000 new fatalities were reported globally – an increase of 25% and 21%, respectively, compared to the previous 28 days. As of 1 January 2023, over 656 million confirmed cases and over 6.6 million deaths have been reported globally.
In this edition, we include:
The COVID-19 epidemiological update at the global and regional levels.
An update on the circulating SARS-CoV-2 variants of concern (VOCs) and Omicron subvariants under monitoring.
An update on hospitalizations and ICU admissions related to COVID-19.

sential for identifying trends and detecting emerging health threats, evaluating the impact of interventions, and guiding evidence-based policy decisions.
This framework outlines a holistic approach to strengthening routine mortality surveillance systems, considering the unique contextual factors and challenges faced by African countries. It emphasizes the importance of establishing efficient data collection mechanisms, enhancing data quality and completeness, and promoting data sharing and collaboration among stakeholders.
Moreover, the framework recognizes the pivotal role of technology in the integration of data from fragmented mortality data sources. It highlights the potential of innovative data capture methods, advanced analytics, and real-time reporting systems to enhance mortality data’s accuracy, efficiency, and timeliness.
The continental framework for mortality surveillance aligns with Africa CDC’s mission and strategic goal by serving as a fundamental component in strengthening public health systems, enhancing disease surveillance capacities and capabilities, informing evidence-based policies and interventions, and promoting collaboration and coordination among African countries to address health challenges and improve health outcomes on the continent.
The successful implementation of this framework requires collective commitment and concerted efforts from governments, health institutions, and the international community. We hope this document will serve as a catalyst for transformative change, enabling countries to build resilient mortality surveillance systems that protect public health, save lives, and contribute to evidence-based decision-making.

évoluer. Des données précises et opportunes sur la mortalité sont essentielles pour identifier les tendances et détecter les menaces émergentes pour la santé, évaluer l'impact des interventions et orienter les décisions politiques fondées sur des données probantes.
Ce cadre décrit une approche holistique pour renforcer les systèmes de surveillance de routine de la mortalité, en tenant compte des facteurs contextuels uniques et des défis auxquels sont confrontés les pays africains. Il souligne l'importance d'établir des mécanismes de collecte de données efficaces, d'améliorer la qualité et l'exhaustivité des données et de promouvoir le partage des données et la collaboration entre les parties prenantes.
De plus, le cadre reconnaît le rôle central de la technologie dans l'intégration des données provenant de sources de données fragmentées sur la mortalité. Il met en évidence le potentiel des méthodes innovantes de capture de données, des analyses avancées et des systèmes de notification en temps réel pour améliorer la précision, l'efficacité et l'actualité des données sur la mortalité.
Le cadre continental de surveillance de la mortalité s'aligne sur la mission et l'objectif stratégique d'Africa CDC en servant d'élément fondamental dans le renforcement des systèmes de santé publique, l'amélioration des capacités et des capacités de surveillance des maladies, l'élaboration de politiques et d'interventions fondées sur des données probantes et la promotion de la collaboration et de la coordination entre les pays africains pour relever les défis sanitaires et améliorer les résultats sanitaires sur le continent.
La mise en œuvre réussie de ce cadre nécessite un engagement collectif et des efforts concertés de la part des gouvernements, des établissements de santé et de la communauté internationale. Nous espérons que ce document servira de catalyseur pour un changement transformateur, permettant aux pays de mettre en place des systèmes de surveillance de la mortalité résilients qui protègent la santé publique, sauvent des vies et contribuent à la prise de décision fondée sur des données probantes.

children are particularly vulnerable, especially those
in low and middle income countries, where they are
exposed on a daily basis to indoor air pollution from
solid fuels for cooking and heating. In high income

for chronic respiratory diseases, and in some of
these countries, tobacco use among women and
young people is still increasing.

This study compares antimicrobial surveillance systems in three low and middle income countries in order to describe the components of these systems and to understand which surveillance models are best suited to particular contexts. Ghana, Nigeria and Nepal were selected as study countries because they cover different continents and include one ‘fragile’ context (Nigeria). Brief information from Malawi is also included.

surveillance is part of the broader surveillance and laboratory system, and its implementation should reinforce end-to-end capacities including sample collection, diagnostics, data sharing and analysis. The strategy aims to facilitate the connectivity between different disease control programs and surveillance networks. This interoperability will strengthen the cross-cutting essential public health laboratory functions underpinning genomics holistically. The strategy articulates the overarching goal, objectives and strategic actions needed. These are dependent on commitments from countries, partners and WHO for their implementation.
