They also provide in-depth discussions of the biology of the viruses, the pathogenesis of the acute and chronic diseases they cause, the methods and ease with which they are transmitted, and their clinical signs and symptoms. Additional topics include diagnostic tests and routine blood screening, new vaccines, and the use of interferon and antiviral drugs. Viral Hepatitis: Diagnosis, Therapy, and Prevention provides the most comprehensive and up-to-date survey of the hepatitis viruses currently available. Rich in the practical details of viral diagnosis, treatment, and prevention, it constitutes today's gold-standard reference on this major health threat for all concerned physicians and researchers.
