Oleribe OO, Taylor-Robinson SD, Taylor-Robinson AW. COVID-19 post-pandemic reflections from sub-Saharan Africa: what we know now that we wish we knew then. PUBLIC HEALTH IN PRACTICE 2024; 7:100486. [PMID: 38495538 PMCID: PMC10943955 DOI: 10.1016/j.puhip.2024.100486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 02/15/2024] [Accepted: 02/19/2024] [Indexed: 03/19/2024] Open
Abstract
The commonly heard aphorism about history repeating itself suggests an endless cycle of recurring events. However, George Santayana offered a similar sentiment when he said, "Those who do not learn from history are doomed to repeat it". This emphasises that the responsibility for the recurrence of events lies not with history itself, but with humanity. It underscores that if we desire change, it is our responsibility to initiate it, rather than attributing it to external forces such as fate, luck, or time. With this thought in mind, here we offer a narrative view from sub-Saharan Africa, focusing primarily on our own experiences in Nigeria and Uganda, on what harsh lessons can be learnt from the COVID-19 pandemic regarding emergency preparedness to respond effectively to the next major infectious disease outbreak. Four strategies are suggested, the implementation of which may contribute substantially to safeguarding against an experience similar to the catastrophic public health, social and economic costs borne by African nations during COVID-19 and in its immediate aftermath.

SARS-CoV-2 seroprevalence and associated factors, based on HIV serostatus, in young people in Sofala province, Mozambique. BMC Infect Dis 2023; 23:809. [PMID: 37978353 PMCID: PMC10656907 DOI: 10.1186/s12879-023-08808-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 11/09/2023] [Indexed: 11/19/2023] Open
Abstract
INTRODUCTION In Sofala province (Mozambique), young people living with HIV (YPLHIV) are estimated at 7% among people aged 15-24 years. Even though the COVID-19 pandemic threatened HIV health services, data on the impact of COVID-19 on YPLHIV people are lacking. This study aimed at exploring the seroprevalence of SARS-CoV-2 and associated factors among young people based on their HIV status. METHODS A cross-sectional study was conducted, including people aged 18-24 attending a visit at one of the adolescent-friendly health services in Sofala province between October and November 2022. People vaccinated against SARS-COV-2 or YPLHIV with WHO stage III-IV were excluded. A SARS-CoV-2 antibodies qualitative test and a questionnaire investigating socio-demographic and clinical characteristics were proposed. SARS-CoV-2 seroprevalence was calculated with Clopper-Pearson method. The odds ratio (OR) of a positive SARS-CoV-2 antibodies test was estimated through multivariable binomial logistic regression. RESULTS In total, 540 young people including 65.8% women and 16.7% YPLHIV participated in the survey.. The mean age was 20.2 years (SD 2.0). Almost all the sample (96.1%) reported adopting at least one preventive measure for COVID-19. The weighted seroprevalence of SARS-CoV-2 in the whole sample was 46.8% (95%CI 42.6-51.2) and 35.9% (95%CI 25.3-47.5) in YPLHIV. The adjusted OR of testing positive at the SARS-CoV-2 antibodies test was higher in students compared to workers (aOR:2.02[0.95CI 1.01-4.21]) and in those with symptoms (aOR:1.52[0.95CI 1.01-2.30]). There were no differences based on HIV status(aOR:0.663[95%CI 0.406-1.069]). Overall, COVID-19 symptoms were reported by 68 (28.2%) people with a positive serological SARS-CoV-2 test and by 7 (21.7%) YPLHIV (p = 0.527). No one required hospitalization. CONCLUSIONS SARS-CoV-2 seroprevalence was 46.8% without differences in risk of infection or clinical presentation based on HIV status. This result may be influenced by the exclusion of YPLHIV with advanced disease. The higher risk among students suggests the schools' role in spreading the virus. It's important to continue monitoring the impact of COVID-19 on YPLHIV to better understand its effect on screening and adherence to treatment.

Spread and seasonality of COVID-19 pandemic confirmed cases in sub-Saharan Africa: experience from Democratic Republic of Congo, Nigeria, Senegal, and Uganda. BMC Infect Dis 2023; 23:187. [PMID: 36991346 PMCID: PMC10054222 DOI: 10.1186/s12879-023-08168-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 03/16/2023] [Indexed: 03/31/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has impacted the world negatively with huge health and socioeconomic consequences. This study estimated the seasonality, trajectory, and projection of COVID-19 cases to understand the dynamics of the disease spread and inform response interventions. METHOD Descriptive analysis of daily confirmed COVID-19 cases from January 2020 to 12th March 2022 was conducted in four purposefully selected sub-Saharan African countries (Nigeria, Democratic Republic of Congo (DRC), Senegal, and Uganda). We extrapolated the COVID-19 data from (2020 to 2022) to 2023 using a trigonometric time series model. A decomposition time series method was used to examine the seasonality in the data. RESULTS Nigeria had the highest rate of spread (β) of COVID-19 (β = 381.2) while DRC had the least rate (β = 119.4). DRC, Uganda, and Senegal had a similar pattern of COVID-19 spread from the onset through December 2020. The average doubling time in COVID-19 case count was highest in Uganda (148 days) and least in Nigeria (83 days). A seasonal variation was found in the COVID-19 data for all four countries but the timing of the cases showed some variations across countries. More cases are expected in the 1st (January-March) and 3rd (July-September) quarters of the year in Nigeria and Senegal, and in the 2nd (April-June) and 3rd (October-December) quarters in DRC and Uganda. CONCLUSION Our findings show a seasonality that may warrant consideration for COVID-19 periodic interventions in the peak seasons in the preparedness and response strategies.

Immune System and Epidemics: The Role of African Indigenous Bioactive Substances. Nutrients 2023; 15:nu15020273. [PMID: 36678143 PMCID: PMC9864875 DOI: 10.3390/nu15020273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 12/28/2022] [Accepted: 12/29/2022] [Indexed: 01/06/2023] Open
Abstract
With over 6 million coronavirus pandemic deaths, the African continent reported the lowest death rate despite having a high disease burden. The African community's resilience to the pandemic has been attributed to climate and weather conditions, herd immunity, repeated exposure to infectious organisms that help stimulate the immune system, and a disproportionately large youth population. In addition, functional foods, herbal remedies, and dietary supplements contain micronutrients and bioactive compounds that can help boost the immune system. This review identified significant traditional fermented foods and herbal remedies available within the African continent with the potential to boost the immune system in epidemics and pandemics. Methodology: Databases, such as PubMed, the Web of Science, and Scopus, were searched using relevant search terms to identify traditional African fermented foods and medicinal plants with immune-boosting or antiviral capabilities. Cereal-based fermented foods, meat-, and fish-based fermented foods, and dairy-based fermented foods containing antioxidants, immunomodulatory effects, probiotics, vitamins, and peptides were identified and discussed. In addition, nine herbal remedies and spices belonging to eight plant families have antioxidant, immunomodulatory, anti-inflammatory, neuroprotective, hepatoprotective, cardioprotective, and antiviral properties. Peptides, flavonoids, alkaloids, sterols, ascorbic acid, minerals, vitamins, and saponins are some of the bioactive compounds in the remedies. Bioactive compounds in food and plants significantly support the immune system and help increase resistance against infectious diseases. The variety of food and medicinal plants found on the African continent could play an essential role in providing community resilience against infectious diseases during epidemics and pandemics. The African continent should investigate nutritional, herbal, and environmental factors that support healthy living and longevity.

Probing SARS-CoV-2-positive plasma to identify potential factors correlating with mild COVID-19 in Ghana, West Africa. BMC Med 2022; 20:370.

Abstract
BACKGROUND West Africa has recorded a relatively higher proportion of asymptomatic coronavirus disease 2019 (COVID-19) cases than the rest of the world, and West Africa-specific host factors could play a role in this discrepancy. Here, we assessed the association between COVID-19 severity among Ghanaians with their immune profiles and ABO blood groups. METHODS Plasma samples were obtained from Ghanaians PCR-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive individuals. The participants were categorized into symptomatic and asymptomatic cases. Cytokine profiling and antibody quantification were performed using Luminex™ multiplex assay whereas antigen-driven agglutination assay was used to assess the ABO blood groups. Immune profile levels between symptomatic and asymptomatic groups were compared using the two-tailed Mann-Whitney U test. Multiple comparisons of cytokine levels among and between days were tested using Kruskal-Wallis with Dunn's post hoc test. Correlations within ABO blood grouping (O's and non-O's) and between cytokines were determined using Spearman correlations. Logistic regression analysis was performed to assess the association of various cytokines with asymptomatic phenotype. RESULTS There was a trend linking blood group O to reduced disease severity, but this association was not statistically significant. Generally, symptomatic patients displayed significantly (p < 0.05) higher cytokine levels compared to asymptomatic cases with exception of Eotaxin, which was positively associated with asymptomatic cases. There were also significant (p < 0.05) associations between other immune markers (IL-6, IL-8 and IL-1Ra) and disease severity. Cytokines' clustering patterns differ between symptomatic and asymptomatic cases. We observed a steady decrease in the concentration of most cytokines over time, while anti-SARS-CoV-2 antibody levels were stable for at least a month, regardless of the COVID-19 status. CONCLUSIONS The findings suggest that genetic background and pre-existing immune response patterns may in part shape the nature of the symptomatic response against COVID-19 in a West African population. This study offers clear directions to be explored further in larger studies.
