The efficacy of oral ribavirin in the treatment of crimean-congo hemorrhagic fever in Iran

Abstract

We compared the mortality rate among patients suspected of having Crimean-Congo hemorrhagic fever (CCHF) who received treatment with oral ribavirin and those who did not. Ninety-seven (69.8%) of 139 treated patients suspected of having CCHF survived, and 61 (88.9%) of 69 treated patients with confirmed CCHF survived. The efficacy of oral ribavirin was 80% among patients with confirmed CCHF and 34% among patients suspected of having CCHF. Considering the limitations of observational studies, we conclude that oral ribavirin is an effective treatment for the hemorrhagic form of CCHF.
