What is post-viral syndrome?

In medicine, the term "post-viral syndrome" refers to a state of fatigue, feeling exhausted, and weakness that lasts after a patient has recovered from a viral infection, typically after the flu. Because fatigue is the main symptom, the syndrome is also called post-viral fatigue syndrome.

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

In addition to fatigue, pain also causes a lot of discomfort, affecting the patient's life with persistent pain, musculoskeletal pain, and nerve pain. In addition, it also causes decreased neurocognition and even sleep disorders.

Symptoms vary from person to person, but most people experience a general feeling of being unwell. This feeling does not improve even after sleeping for many hours or taking good care of themselves. Patients also often describe signs such as: not being alert, difficulty concentrating, headaches, muscle aches, stiff joints, sore throat, swollen glands...

This condition can last for weeks, months, or even years. It is caused by the body's response to the virus itself.
