What is post-viral syndrome?

In medicine, the term "post-viral syndrome" refers to a state of fatigue, exhaustion, and prolonged weakness that occurs after a patient has recovered from a viral infection, typically the aftermath of influenza. Because fatigue is the primary symptom, the syndrome is also known as post-viral fatigue syndrome.

Contrary to popular belief, this syndrome is quite common, characterized by varying degrees of physical, cognitive, and emotional impairment, with different durations and severity levels, during the post-recovery phase of an acute viral infection.

Besides fatigue, pain also causes significant discomfort, affecting patients' lives with persistent pain, musculoskeletal pain, and nerve pain. Furthermore, it can lead to reduced cognitive function and even sleep disorders.

Symptoms vary widely and from person to person, but most experience a general feeling of unwellness. This feeling doesn't improve even after hours of sleep or taking good care of oneself. Patients also frequently describe symptoms such as: lack of alertness, difficulty concentrating, headaches, muscle aches, stiffness, sore throat, swollen lymph nodes, etc.

This condition can last for weeks, months, or even years. The cause of the syndrome is the body's reaction to the virus that has infected it.
