Dengue and Typhoid: A Duet of Choreoathetosis

Choreoathetoid movements can be caused by a range of conditions. Here, we discuss the case of a 16-year-old male with a history of acute febrile illness who presented with features typical of paroxysmal dystonic choreoathetosis. He arrived at the hospital complaining of a fever that had been present for four days, suggesting a viral etiology, but he did not exhibit any involuntary movements. The routine panel suggests both dengue and typhoid as potential culprits. Consequently, during the ward stay, the patient developed involuntary movements in bilateral upper limbs, lower limbs, and face. Co-infection with both dengue and typhoid is seldom seen, with an increasing number of cases in the recent few years. These situations can sometimes put the treating physician in a difficult situation with respect to management. This case is being discussed because of its rare manifestation caused by a rare co-infection.
