Post Viral Pain, Fatigue, and Sleep Disturbance Syndromes: Current knowledge and Future Directions

Post-viral pain syndrome, also known as post-viral syndrome (PVS), is a complex condition characterized by persistent pain, fatigue, musculoskeletal pain, neuropathic pain, neurocognitive difficulties, and sleep disturbances1,2 that can occur after an individual has recovered from a viral infection. Much remains unknown regarding the pathophysiology of post-viral syndromes and few studies have provided a comprehensive summary of the condition, agents that cause it, and successful treatment modalities. With the COVID-19 pandemic continuing to affect millions of people worldwide, the need for understanding the etiology of post-viral illness and how to help individuals cope with the sequalae is paramount.2 This narrative review provides a summary of the sequelae of post-viral syndromes, viral agents that cause it, the pathophysiology, treatment, and future considerations for research and targeted therapies.
