Lately, a large number of people who were treated for Covid-19 or viral infection are experiencing fatigue syndrome that slows down recovery, said health experts. Viruses that have been dormant can cause inflammation of the nerves leading to symptoms like chronic tiredness, bodyache, poor attention, irritability, etc. People should, however, not panic, they said, adding that light exercises and gradual return to your daily routine would help.

The symptoms range from chronic tiredness or sleepiness to headaches, dizziness, sore, achy or weak muscles, slow reflexes and responses, poor decision-making skills, moodiness and irritability, etc., they added. Dr Wiqar Shaikh, professor of Medicine at Grant Medical College and Sir JJ Group of Hospitals, defined fatigue as an overall feeling of tiredness or exhaustion. He said it is completely normal to have fatigue for some time after a viral infection. However, post-viral fatigue (PVF) can sometimes linger on for weeks or even months.
