 The COVID-19 pandemic has raised concerns about potential links between the virus and other viruses such as herpes virity. This paper reviews the evidence for these links and concludes that herpes virity can be used as prognostic markers for COVID-19 infection and may even underlie some of its clinical manifestations. Furthermore, it appears that all vaccines currently available in Europe are capable of inducing herpes virus reactivation. Therefore, it is important to consider all viruses of the herpes virity family when managing patients infected with or recently vaccinated against COVID-19.
