Abstract:
Chronic fatigue syndrome (CFS) is often preceded by a viral illness and has recurrent ‘flulike’ symptoms which include a wide spectrum of musculoskeletal and neurological clinical features. The condition is also known as myalgic encephalomyelitis and systemic exertional intolerance syndrome. CFS has been reported following dengue among adult patients. We report the case of an 11-year-old boy who developed CFS following recovery of dengue haemorrhagic fever (DHF). The reported child was initially managed as for DHF and was clinically asymptomatic on post-discharge day 3. He was re-admitted after 3 weeks with severe joint pains, myalgia and unbearable headache. As his symptoms persisted, he was investigated in-depth. All investigations were normal except mild elevation of liver functions. The diagnosis of CFS secondary to DHF was made by exclusion of differential diagnosis. At 1-year follow-up, patient continues to have symptoms after treatment with physiotherapy and nutrition counselling.
