A BSTRACT Background: Dengue virus (DENV) infections are endemic in nearly all regions of Indonesia, presenting a spectrum of clinical manifestations from dengue fever to more severe forms such as dengue hemorrhagic fever (DHF) and dengue shock syndrome. Thrombocytopenia, a significant DENV infection diagnostic indicator, can lead to bleeding complications. This study aimed to investigate the characteristics of thrombocyte counts and bleeding manifestations in DHF patients. Subjects and Methods: A descriptive-analytical study with a cross-sectional approach was conducted using secondary data from medical records of DHF patients treated at Wangaya Hospital between July and December 2023. After applying inclusion and exclusion criteria, 142 cases were included in the analysis. Data were analyzed using univariate analysis with SPSS software. Results: The findings revealed that the majority of DHF patients were adults (73.9%) and males (58.5%). Most patients had mild thrombocytopenia on their first laboratory examination (57.7%), and 70.4% of cases showed no bleeding manifestations. Conclusions: DHF predominantly affects adult males and is associated with mild thrombocytopenia in the early stages. Bleeding manifestations are uncommon and are observed in less than a third of cases. These findings highlight the variability of clinical presentations in DHF and the importance of early laboratory diagnostics in patient management.
