We describe 7,421 chikungunya hospitalizations in Brazil covered by the country's unified health system during 2014-2024. Most (43.2%) hospitalizations occurred in 2016 and 2017, reaching 0.72 (95% CI 0.69-0.76) hospitalizations/100,000 population in 2016. Hospitalizations were more frequent among persons who were female (55.8%), identifying as brown or black (63.5%), and 1-19 years of age (31.4%). Intensive care unit admissions occurred in 1.4% of cases, predominantly among children 85 years of age. The overall in-hospital case-fatality rate was 1.1%, which increased substantially with age, reaching 11.5% among patients >90 years of age and 14.1% among men 85-89 years of age. Patients admitted to the intensive care unit had a case-fatality rate of 21.1%. The total cost of chikungunya hospitalizations was US $560,746 (US $76.26 per patient). Our findings provide insights for surveillance of the most severe chikungunya cases.
