Treatment of Crimean-Congo Haemorrhagic Fever by Favipiravir in a Patient with Novel Coronavirus Co-Infection

Abstract

Introduction: Crimean-Congo haemorrhagic fever (CCHF) is a lethal zoonotic disease caused by an RNA virus that is a member of the Nairovirus genus in the Bunyaviridae family from the arbovirus group. CCHF is transmitted by Hyalomma ticks through direct contact with the blood and other bodily fluids of patients or infected animals. Case description: A 65-year-old man was admitted to the emergency unit with dry cough, myalgia and fever. He was treated with favipiravir. He had disseminated intravascular coagulopathy with thrombocytopenia in the setting of COVID-19 infection. He tested positive for both COVID-19 and CCHF. By the end of the fifth day of treatment, his laboratory parameters and clinical symptoms had normalized. Conclusion: Favipiravir is currently on the market for treating COVID-19 infection worldwide. It has also been used to treat CCHF in laboratory animals. To the best of our knowledge this is the first report of CCHF successfully treated with favipiravir, which could be a key drug for treating human CCHF.
