Clinical and Epidemiologic Features of Crimean-Congo Hemorrhagic Fever Patients in Giresun Province

Aim: Crimean-Congo hemorrhagic fever (CCHF) is an endemic disease in our country that can result in mortality. This study aimed to investigate the clinical and epidemiological characteristics of CCHF cases in our province. Methods: A retrospective analysis was conducted on 92 adult CCHF cases diagnosed in our province between 2021 and 2024. The demographic, clinical, and laboratory data of these patients were evaluated, along with the geographical and seasonal distribution of the disease. Results: The mean age of the 92 patients diagnosed with CCHF was 52.7±14.9 years. Of the patients, 53.3% were male. The vast majority had a history of tick exposure, farming, or animal husbandry. The most common symptoms were fatigue, fever, and muscle-joint pain. The majority of the cases were reported from the districts of Şebinkarahisar, Alucra, and Çamoluk, in that order. Cases began to appear in April, with distribution throughout the year ending in August. Most cases were admitted in May, June, and July. Mortality occurred in 3 patients (3.3%). Conclusion: CCHF cases in Giresun Province are predominantly seen in individuals living in rural areas and engaged in agricultural activities, with a marked seasonal distribution. The concentration of cases in specific districts indicates the need to intensify public health measures in these areas. The findings of this study may contribute to understanding the regional spread of CCHF and to the development of preventive strategies.
