abstract = {\<p\>Background: After its initial detection in Wuhan, China, in December 2019, SARS-CoV-2 has spread rapidly, causing successive epidemic waves worldwide. This study aims to provide a genomic epidemiology of SARS-CoV-2 in Burkina Faso. Methods: Three hundred and seventy-seven SARS-CoV-2 genomes obtained from PCR-positive nasopharyngeal samples (PCR cycle threshold score \< 35) collected between 5 May 2020, and 31 January 2022 were analyzed. Genomic sequences were assigned to phylogenetic clades using NextClade and to Pango lineages using pangolin. Phylogenetic and phylogeographic analyses were performed to determine the geographical sources and time of virus introduction in Burkina Faso. Results: The analyzed SARS-CoV-2 genomes can be assigned to 10 phylogenetic clades and 27 Pango lineages already described worldwide. Our analyses revealed the important role of cross-border human mobility in the successive SARS-CoV-2 introductions in Burkina Faso from neighboring countries. Conclusions: This study provides additional insights into the genomic epidemiology of SARS-CoV-2 in West Africa. It highlights the importance of land travel in the spread of the virus and the need to rapidly implement preventive policies. Regional cross-border collaborations and the adherence of the general population to government policies are key to prevent new epidemic waves.\</p\>},

abstract = {BACKGROUND: The world has high hopes of vaccination against 

 COVID-19 to protect the population, boost economies and return to 

 normal life. Vaccination programmes are being rolled out in high 

 income countries, but the pandemic continues to progress in many 

 low-and middle-income countries (LMICs) despite implementation of 

 strict hygiene measures. We aim to present a comprehensive 

 research protocol that will generate epidemiological, 

 sociological and anthropological data about the COVID-19 epidemic 

 in Burkina Faso, a landlocked country in West Africa with scarce 

 resources. METHODS: We will perform a multidisciplinary research 

 using mixed methods in the two main cities in Burkina Faso 

 (Ouagadougou and Bobo-Dioulasso). Data will be collected in the 

 general population and in COVID-19 patients, caregivers and 

 health care professionals in reference care centers: (i) to 

 determine cumulative incidence of SARS-CoV-2 infection in the 

 Burkinabe population using blood samples collected from randomly 

 selected households according to the WHO-recommended protocol; 

 (ii) develop a score to predict severe complications of COVID-19 

 in persons infected with SARS-CoV-2 using retrospective and 

 prospective data; (iii) perform semi-structured interviews and 

 direct observation on site, to describe and analyze the 

 healthcare pathways and experiences of patients with COVID-19 

 attending reference care centers, and to identify the 

 perceptions, acceptability and application of preventive 

 strategies among the population. DISCUSSION: This study will 

 generate comprehensive data that will contribute to improving 

 COVID-19 response strategies in Burkina Faso. The lessons learned 

 from the management of this epidemic may serve as examples to the 

 country authorities to better design preventive strategies in the 

 case of future epidemics or pandemics. The protocol was approved 

 by the Ministry for Health (N° 2020-00952/MS/CAB/INSP/CM) and the 

 Health Research Ethics Committee in Burkina Faso (N° 2020-8-140).},

abstract = {OBJECTIVES: The overall death toll from COVID-19 in Africa is 

 reported to be low but there is little individual-level evidence 

 on the severity of the disease. This study examined the clinical 

 spectrum and outcome of patients monitored in COVID-19 care 

 centres (CCCs) in two West-African countries. METHODS: Burkina 

 Faso and Guinea set up referral CCCs to hospitalise all 

 symptomatic SARS-CoV-2 carriers, regardless of the severity of 

 their symptoms. Data collected from hospitalised patients by 

 November 2020 are presented. RESULT: A total of 1,805 patients 

 (64% men, median age 41 years) were admitted with COVID-19. 

 Symptoms lasted for a median of 7 days (IQR 4-11). During 

 hospitalisation, 443 (25%) had a SpO2 \< 94% at least once, 237 

 (13%) received oxygen and 266 (15%) took corticosteroids. 

 Mortality was 5% overall, and 1%, 5% and 14% in patients 

 aged \<40, 40-59 and $geq$60 years, respectively. In 

 multivariable analysis, the risk of death was higher in men (aOR 

 2.0, 95% CI 1.1; 3.6), people aged $geq$60 years (aOR 2.9, 

 95% CI 1.7; 4.8) and those with chronic hypertension (aOR 2.1, 

 95% CI 1.2; 3.4). CONCLUSION: COVID-19 is as severe in Africa 

 as elsewhere, and there must be more vigilance for common risk 

 factors such as older age and hypertension.},
