Evaluation of Serum Ferritin Levels and Their Correlation With Clinical Outcomes in Dengue Virus Infection in a Population of Older Adults

Our study found higher levels of ferritinemia in cases of severe dengue and in the critical and convalescent phases, with statistically significant differences. Age over 60 may be associated with the development of severe dengue, and hyperferritinemia may represent a biomarker of dengue severity.
