The annual increase of new cases of VD among the inhabitants of industrialized countries reaches 2.6% among women and 1.9% among men. Its course is accompanied by a number of complications and a high level of disability of patients, which, in turn, is associated with significant economic costs. These circumstances make the development of an effective system for diagnosing VD an important medical and social problem.</p>Kazan Medical archiveКазанский медицинский архив
