Post-recovery fatigue is not uncommon after illnesses like dengue. It can take some time for the body to fully regain its energy levels, even if the symptoms have subsided. It's possible that your mother's body is still in the process of recovering and rebuilding her strength. However, if this fatigue persists or worsens, it's essential for her to consult a physician  to rule out any other underlying issues or complications related to dengue or any other health conditions.
