XBB.1, BQ1.1 and atypical BA.4.6/XBB.1 recombinants predominate current SARS-CoV-2 Wavelets with flu-like symptoms in Cameroon: A snapshot from genomic surveillance.

As of December 2022, Cameroon had observed a slight resurgence of COVID-19, raising concerns on genomic surveillance of related-SARS-CoV-2 variants under circulation. Following a laboratory-based survey, positive SARS-CoV-2 samples detected from December-2022 through March-2023 were processed for targeted sequencing at the Chantal BIYA International Reference Centre (CIRCB) in Yaoundé-Cameroon. From all positive cases detected, 13 were successfully sequenced (mean age 34 years, 70% female); the majority of the cases were unvaccinated (70%, 9/13) and symptomatic (92%, 12/13); all with flu-like symptoms (100%, 12/12).

African leadership is critical in responding to public health threats.

The African continent demonstrated decisive leadership throughout its response to the COVID-19 pandemic, leveraging lessons learned from previous outbreaks and acting quickly to limit the impact of the SARS-CoV-2 virus. We propose a framework to build on these successes that calls for greater collaboration between African leaders, and greater inclusion of African voices in the global health ecosystem.

Experiences of adolescents and youth with HIV testing and linkage to care through the Red Carpet Program (RCP) in Kenya.

Adolescents and youth living with HIV (AYLHIV) experience worse health outcomes compared to adults. We aimed to understand the experiences of AYLHIV in care in the youth-focused Red-Carpet program in Kenya to assess the quality of service provision and identify programmatic areas for optimization. We conducted focus group discussions among 39 AYLHIV (15-24 years) and structured analysis into four thematic areas.

Genomic surveillance of SARS-CoV-2 reveals highest severity and mortality of delta over other variants: evidence from Cameroon.

While the SARS-CoV-2 dynamic has been described globally, there is a lack of data from Sub-Saharan Africa. We herein report the dynamics of SARS-CoV-2 lineages from March 2020 to March 2022 in Cameroon. Of the 760 whole-genome sequences successfully generated by the national genomic surveillance network, 74% were viral sub-lineages of origin and non-variants of concern, 15% Delta, 6% Omicron, 3% Alpha and 2% Beta variants.

Non-calcified plaque in asymptomatic patients with zero coronary artery calcium score: A systematic review and meta-analysis.

Background: There is growing interest in understanding the coronary atherosclerotic burden in asymptomatic patients with zero coronary artery calcium score (CACS). In this population, we aimed to investigate the prevalence and severity of non-calcified coronary plaques (NCP) as detected by coronary CT angiography (CCTA), and to analyze the associated clinical predictors.

Methods: This was a systematic review with meta-analysis of studies indexed in PubMed/Medline and Web of Science from inception of the database to March 31st, 2023.

A systematic review and meta-analysis of the prevalence, incidence, and predictors of atrial fibrillation in cardiac sarcoidosis.

Background: The occurrence of atrial arrhythmias, in particular, atrial fibrillation (AF) in patients with cardiac sarcoidosis (CS) are of growing interest in the field of infiltrative cardiomyopathies. Via a systematic review with meta-analysis, we sought to synthesize data on the prevalence, incidence, and predictors of atrial arrhythmias as well as outcomes in patients with CS.

Methods: PubMed/Medline, Web of Science, and Scopus were systematically queried from inception until April 26th, 2023.

A comprehensive review of cystic fibrosis in Africa and Asia.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of . Here, we discuss the evidence of CF in parts of the world earlier considered to be rare; Africa, and Asia.

The SPIN framework to control and prevent the Marburg virus disease outbreak in Equatorial Guinea.

A full grasp of the epidemiological factors promoting transmission is necessary for responding to highly infectious diseases, which involves their control and prevention. With the recent outbreak of Marburg Virus Disease (MVD) in Equatorial Guinea, we saw the need to re-shed some technical light based on our field experiences and published literature. We reviewed 15 previous MVD outbreaks globally.

Modeling the Lassa fever outbreak synchronously occurring with cholera and COVID-19 outbreaks in Nigeria 2021: A threat to Global Health Security.

Nigeria struggles with seasonal outbreaks of Lassa fever (LF), with 70 to 100% of its states affected annually. Since 2018, the seasonal dynamics have changed with a stark increase in infections, though the pattern in 2021 differed from the other years. Nigeria had three outbreaks of Lassa Fever in 2021.

An epidemiological synthesis of emerging and re-emerging zoonotic disease threats in Cameroon, 2000-2022: a systematic review.

Introduction: Population factors such as urbanization, socio-economic, and environmental factors are driving forces for emerging/re-emerging zoonotic diseases in Cameroon. To inform preparedness and prioritization efforts, this study mapped out epidemiological data (including prevalence) of zoonotic diseases occurring in Cameroon between 2000 and 2022 by demographic factors.

Methods: Following the PRISMA guidelines, a protocol was registered in the PROSPERO database (CRD42022333059).

Health diplomacy in Africa-opportunities post-COVID-19.

For the last seventy years, Africa has suffered a disease burden that is steadily growing in scale and complexity. Despite that, health development in the continent has continued to rely on donors´ packages since decolonization. The last decade, however, has marked some health-related achievements on the continent such as the development of the Africa Health Strategy 2016-2030, the establishment of Africa Centres for Disease Control and Prevention (Africa CDC), the launch of The African Continental Free Trade Area (AfCFTA) and most recently the African Medicines Agency (AMA).
