A Rare Triad: Chikungunya-Associated Myocarditis and Guillain–Barré Syndrome — A Case Report

Chikungunya is a mosquito-borne viral disease caused by the chikungunya virus, typically presenting with a sudden onset of fever and severe joint pain. While the disease generally follows a benign course, it can lead to severe complications like myocarditis, encephalitis, and Guillain–Barré syndrome (GBS). We report the case of a 53-year-old male with a history of hypertension and diabetes mellitus, who was recently diagnosed with chikungunya infection. He presented with shortness of breath and fever and was subsequently diagnosed with chikungunya-associated myocarditis. During his hospital stay, he developed GBS. He was managed with corticosteroids, diuretics, intravenous immunoglobulin (IVIG), and supportive care. This case highlights the rare but severe neurological and cardiac complications that may arise in the course of chikungunya infection.
