Post-COVID-19 condition, or long COVID, refers to symptoms lasting for three months or more following acute COVID-19. This condition affects multiple organ systems, including the respiratory, cardiovascular, and neurological systems, leading to a range of symptoms such as fatigue, shortness of breath, chest pain, and brain fog. For many, these symptoms result from organ damage during the initial infection, causing significant and long-lasting health issues that impose a heavy burden on individuals, healthcare systems, and economies worldwide.

This interdisciplinary review combines recent literature on long COVID’s epidemiology, pathophysiology, clinical symptoms, and management. Studies show that approximately 10–30% of individuals recovering from acute COVID-19 may experience prolonged symptoms, with risk factors including older age, pre-existing health conditions, and severity of the initial infection. The varied symptoms, from physical pain to cognitive difficulties, underscore the need for a multi-pronged approach to treatment.

Current treatment options are mostly supportive and symptom-focused, involving physical therapy, medication for symptom relief, and mental health support. However, recent advancements in clinical profiling and biomarker identification offer promising avenues for more targeted, personalized care. For instance, identifying biomarkers associated with inflammation or immune dysregulation could guide treatment protocols and improve recovery outcomes.

The review also examines the organization of healthcare services for long COVID patients, emphasizing the need for specialized clinics and coordinated care models to manage the complexity of this condition. Prevention strategies, including vaccination and early intervention, are explored, highlighting their potential to reduce the incidence and severity of long COVID.

Finally, the review identifies critical areas for future research, including the long-term impacts on different populations, more effective treatments, and strategies for preventing this debilitating condition.1
