Its incidence varies in Europe from 14 to 40%. In Moscow, according to the Institute of Virology named after D.I. Ivanovsky of the USSR Academy of Medical Sciences, it accounts for 15-20%. The term "viral hepatitis neither A nor B" is usually used to refer to a disease caused by an agent having no serological similarity with the causative agent of viral hepatitis A or B. However, all nosological forms of viral hepatitis are characterized by similar clinical symptoms of biochemical changes, which makes their identification difficult.</p>Kazan Medical archiveКазанский медицинский архив
