Clinical Scorecard: Exploring the Determinants of Long COVID in Sub-Saharan Africa: A Scoping Review
At a Glance
Category
Detail
Condition
Long COVID (Post-COVID-19 syndrome, PASC)
Key Mechanisms
Persistence or new onset of symptoms beyond acute SARS-CoV-2 infection, affecting multiple organ systems
Target Population
Individuals in sub-Saharan Africa with prior probable or confirmed SARS-CoV-2 infection
Care Setting
Primary and specialized healthcare settings with limited diagnostic and follow-up resources
Key Highlights
Long COVID affects 10-30% of COVID-19 patients globally, with emerging evidence of significant burden in sub-Saharan Africa despite limited data.
Definitions of long COVID vary internationally, complicating diagnosis and comparison; WHO defines it as symptoms persisting ≥3 months post-infection.
Sub-Saharan Africa faces unique challenges including youthful population, high prevalence of infectious and non-communicable comorbidities, limited healthcare resources, and socio-economic factors impacting diagnosis and management.
Guideline-Based Recommendations
Diagnosis
Use WHO criteria: symptoms persisting at least 2 months, starting usually 3 months after COVID-19 onset, unexplained by other diagnoses.
Recognize heterogeneity of symptoms affecting multiple organ systems including fatigue, respiratory, cognitive, neuropsychiatric, and gastrointestinal manifestations.
Adapt diagnostic criteria to local resource constraints and consider probable cases where confirmatory testing is limited.
Management
Implement context-appropriate post-COVID rehabilitation programs, noting that less than 30% of sub-Saharan countries currently have such programs.
Address comorbidities such as HIV/AIDS, tuberculosis, malaria, hypertension, and diabetes in management plans.
Incorporate traditional medicine practices where culturally relevant, ensuring integration with biomedical care.
Monitoring & Follow-up
Establish epidemiological surveillance systems for long COVID despite resource limitations.
Train healthcare personnel in recognition and management of post-COVID sequelae.
Coordinate care across fragmented health systems to improve follow-up and patient outcomes.
Risks
High risk of under-diagnosis due to limited access to testing and healthcare.
Socioeconomic factors such as poverty, overcrowding, and informal employment hinder isolation and care adherence.
Comorbid infectious and non-communicable diseases may increase susceptibility and complicate clinical course.
Patient & Prescribing Data
Individuals in sub-Saharan Africa with prior SARS-CoV-2 infection experiencing persistent symptoms
Limited data on pharmacological treatments; emphasis on supportive care, rehabilitation, and management of comorbidities tailored to resource availability
Clinical Best Practices
Harmonize diagnostic criteria regionally to improve case identification and comparability.
Develop and expand post-COVID rehabilitation services adapted to local healthcare capacities.
Integrate multidisciplinary approaches including mental health support and management of chronic diseases.
Enhance training of healthcare workers on long COVID recognition and management.
Promote community engagement and culturally sensitive communication to improve health-seeking behavior.
