Crimean-Congo Hemorrhagic Fever (CCHF) is an acute viral zoonotic disease. Coronavirus disease-2019(COVID-19) is a newly emerging viral disease and it is caused by “severe acute respiratory syndromecoronavirus-2 (SARS-CoV-2)”. In this article, a case diagnosed with CCHF and COVID-19 coinfection confirmed by the polymerase chain reaction (PCR) method and its management was presented. A thirty five years old female patient admitted to the hospital with the complaint of fever for one day and commonbody pain. It was learned that three days before the onset of her complaints, she removed a tick adheringto the anterior abdominal wall with no precaution. Her body temperature was 38°C degrees and herrespiratory rate was 22 per minute. The leucocyte count was 3660/mm³ and the platelet count was138.000/mm³. It was determined that prothrombin time was 15.4 seconds, international normalizedratio (INR) was 1.35 seconds, and D-dimer level was 1310 ng/ml. The patient was hospitalized with pre diagnosis of CCHF. Supportive treatment was started. On the second day at the clinical follow-up of thepatient, complaints of sore throat and cough without sputum started. A combined nasopharyngeal andthroat swab sample was taken from the patient because of the suspicion of COVID-19. COVID-19 PCR testresult was reported as positive. Favipiravir treatment was started. The CCHF-PCR test, which was studiedfrom the serum sample sent to the Microbiology Reference Laboratories was reported as positive. Fromthe third day of favipiravir treatment; the patient did not have a fever and her complaints regressed. Onthe ninth day of her hospitalization, she was discharged. In this case; it is important to show that bothdiseases, especially in regions where CCHF disease is endemic, can be confused due to the similarity of theclinical picture with COVID-19 and to know that they can coexist.
