Management of Fatigue in Dengue
Initial Assessment and Screening
- The American College of Physicians recommends screening fatigue severity using a 0-10 numeric rating scale at every clinical encounter, with scores ≥4 requiring comprehensive evaluation 1
- Assess the multidimensional character of fatigue including physical, cognitive, and emotional domains 3, 4, 5
- Document onset timing relative to dengue infection, daily pattern, duration, and factors that worsen or improve symptoms 1
- Evaluate impact on daily activities and functional capacity, as similar fatigue scores produce vastly different disability levels 1, 6
Comprehensive Evaluation for Moderate-to-Severe Fatigue
- Perform complete blood count with differential to evaluate for persistent anemia 2, 1
- Obtain comprehensive metabolic panel to assess electrolyte disturbances and organ function 1, 6
- Check thyroid function tests to exclude hypothyroidism 1, 6
- Measure inflammatory markers and creatine kinase if muscle pain is prominent 6
Treatment Algorithm
- Treat anemia if hemoglobin is low using iron supplementation or erythropoietin as clinically indicated 1, 6
- Initiate antidepressants if depression is present, as this is a Category 1 recommendation for fatigue management 1, 6
- Implement cognitive behavioral therapy for insomnia if sleep disturbance is identified 1, 6
- Restore nutrient deficiencies with appropriate supplementation and dietitian referral when necessary 2
Non-Pharmacological Interventions
- Prescribe tailored physical activity starting at low intensity and gradually increasing based on tolerance 7, 8, 1
- Recommend moderate aerobic exercise 3-5 times weekly, tailored to functional status 1, 6
- Consider gentle movement-based therapies such as tai chi, qigong, or yoga as alternatives 7, 8
- Offer cognitive behavioral therapy delivered by trained providers, which shows benefit for persistent fatigue 7, 8, 1
