Dengue fever is an arboviral disease caused by the dengue virus transmitted by the bite of female Aedes aegypti mosquitoes, affecting people worldwide often causing pandemics in Southeast Asian countries. Dengue viral infection symptoms range from flu-like illness to complications like pneumonia, and hepatitis, neurologic symptoms like encephalitis, myopathy, Guillain–Barre syndrome, phrenic neuropathy, subdural hematoma, and cerebral vasculitis. The possibility of skeletal muscle invasion causing myositis is another rare entity. We are reporting a case of dengue, with myositis presenting as muscle weakness, decreased power, and raised creatinine phosphokinase (CPK) level in a 6-year-old boy. The boy suffered from dengue viral fever diagnosed by positive NS1 antigen. Initially, the symptoms were like uncomplicated dengue fever but later he developed leg muscle pain, and decreased range of movements. The serum CPK level was increased and then the boy was diagnosed with myositis. Later with supportive treatment, he improved, the pain subsided, the power and tone of his leg muscles increased and the serum CPK level returned to normal.
