Abstract
Treatments for infections with hepatitis B and C viruses have recently developed markedly and range from nonspecific interferonbased treatments to specific antiviral treatments such as those that inhibit hepatitis viruscoded protein production or activity These developments have contributed to the achievement of excellent enhancement of the antiviral effect On the other hand the development of specific antiviral therapies has created unprecedented problems Antiviral drugresistant strains of viruses have emerged leading to a poor prognosis for infected patients Clarification of the mechanisms underlying the emergence of such resistance to drugs will be useful for the treatment of such patients In this review we outline pathological conditions associated with hepatitis B and C viruses and their treatments and discuss the current situation and mechanisms underlying the emergence of antiviral drugresistant strains
