Overview of Long COVID: Navigating the Aftermath

The coronavirus disease (COVID-19) pandemic was a global health crisis with far-reaching consequences. Among these were physical and mental health complications that emerged weeks or even months after the initial COVID-19 infection, collectively termed "long COVID" or "post-COVID syndrome." Identifying the epidemiology, risk factors, clinical manifestations, and management strategies for long COVID is crucial for both clinicians and patients, which is the focus of this review. The prevalence of long COVID varies across studies, generally ranging from 5% to 20%. Prominent risk factors include female sex, older age, a high number of acute symptoms, lower socioeconomic status, and underlying comorbidities such as diabetes, asthma, or chronic obstructive pulmonary disease. The clinical manifestations of long COVID are diverse; beyond the commonly reported symptoms of fatigue, malaise, ageusia, and anosmia, neuropsychiatric complications such as headache, cognitive deficits, and depression are also potential outcomes. Although there is currently no consensus on the management of long COVID, multidisciplinary care teams with appropriate referrals and follow-up diagnostic studies are essential in evaluating the clinical course of long COVID patients.
