Modification of the course of post-COVID syndrome associated with reactivation of chronic persistent Epstein−Barr virus infection and chronic nasopharyngotonsillitis of mixed etiology

Abstract

A wide range of symptoms that occur in patients with post-COVID syndrome can include both manifestations of the clinical consequences of COVID-19 and symptoms of an exacerbation of a chronic pathology that they had before the development of coronavirus infection. Correct assessment of clinical data can help determine the origin of the existing manifestations of the disease and build a plan for adequate diagnostic and therapeutic measures. In the article, on the example of a clinical case, a variant of the modified (exacerbation of chronic pathology) course of the post-COVID syndrome was analyzed. An example of modern laboratory diagnostics of reactivation of chronic persistent EpsteinBarr virus infection and exacerbation of chronic nasopharyngotonsillitis of mixed viral-bacterial-mycotic etiology, developed against the background of post-COVID syndrome, is given. The principles of therapy for this comorbid condition are presented and explained.
