Examination of the specific clinical symptoms and laboratory findings of Crimean-Congo hemorrhagic fever

WOS:000380249800011 PubMed: 27353587 Background & objectives: Crimean-Congo hemorrhagic fever (CCHF) is a fatal disease, caused by a tick-borne virus (Nairovirus), having a high mortality rate. The study was aimed to evaluate the risk factors, the presenting symptoms and findings of the patients with prediagnosis of CCHF disease, and to compare these variables between the CCHF-positive and CCHF-negative patients. It was also aimed to develop a scoring formula for the diagnosis of CCHF. Methods: In total, 281 patients who were admitted to the Sabuncuoglu Serafeddin Training and Research Hospital, Amasya, Turkey between 2011 and 2015 and were prediagnosed with CCHF based on the clinical symptoms, laboratory findings and risk factors were included in the study. The definitive laboratory diagnosis of patients with prediagnosis of CCHF was ensured via molecular and serological methods. In addition, a mathematical diagnostic scoring formula was developed for enhancing the laboratory results of CCHF. Results: The ratio of certain clinical symptoms such as fever (p
