Social approaches to COVID-19 pandemic response: effectiveness and practicality in sub-Saharan Africa.

INTRODUCTION: the threat of the coronavirus disease 2019 (COVID-19) pandemic to health systems and communities in sub-Saharan Africa (SSA) is enormous. Social approaches such as distancing measures are essential components of the public health response to respiratory-related infectious disease outbreaks. Due to socio-economic and broader peculiarities of SSA countries, social approaches that were effective elsewhere may have limited practicality in these contexts, and if practical; may yield different or even adverse results. We highlighted the effectiveness of these social approaches and their practicality in SSA. METHODS: we conducted a comprehensive literature search through multiple databases, to identify articles relevant to social distancing. Findings were thematically summarized. RESULTS: our review found emerging and varying empirical evidence on the effectiveness of social approaches in the control and mitigation of the COVID-19 pandemic; thus, limiting its applicability in SSA contexts. Nonetheless, our review demonstrates that the effectiveness and practicality of social approaches in SSA contexts will depend on available resources; timing, duration, and intensity of the intervention; and compliance. Weak political coordination, anti-science sentiments, distrust of political leaders and limited implementation of legal frameworks can also affect practicality. CONCLUSION: to overcome these challenges, tailoring and adaptation of these measures to different but unique contexts for maximum effectiveness, and investment in social insurance mechanisms, are vital.

Cochrane corner: convalescent plasma or hyperimmune immunoglobulin for people with COVID-19.

As the novel coronavirus continues to spread globally and across Africa, efforts are being accelerated to identify effective preventive and therapeutic measures to mitigate its burden. Convalescent plasma and hyperimmune immunoglobulin are being considered as potential therapeutic options for the coronavirus disease 2019 (COVID-19). We highlight and contextualize the findings of a recent Cochrane rapid review that evaluated the effectiveness and safety of convalescent plasma or hyperimmune immunoglobulin transfusion in the treatment of people with COVID-19. From the eight studies it included, the review found limited and low-certainty evidence on the effectiveness and safety of convalescent plasma therapy in patients with COVID-19. The evidence was limited by the small number of participants and low-quality of included studies, as well as the inconsistency of outcome measures and reporting across studies. As African countries brace for the further spread of the virus, while exploring potential therapeutic options to mitigate its morbidity and mortality at peak, convalescent plasma transfusion may offer a therapeutic ray of hope for the continent. Considering the limited evidence of the effectiveness and safety in the treatment of COVID-19, it is imperative for this therapy to be investigated within African contexts to ascertain not only its effectiveness and safety, but also its practical implications within the capacity of national blood transfusion services and health systems in the region.
