abstract：:Ribavirin is the first synthetic, broad-spectrum antiviral nucleoside. Despite its more than 30 year history, the mechanism of action of this compound remains unclear and somewhat controversial. Recent data suggest the possibility that the activity of ribavirin against RNA viruses is a reflection of incorporation of r...
