Abstract:
The appearance on the skin of herpes virus lesions, concomitantly with the coronavirus disease 2019 (COVID-19) pandemic, leads us to suspect an underlying infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Diagnostic reverse transcriptase polymerase chain reaction tests and immunoglobulin M (IgM) and IgG seroconversion studies have therefore been carried out. We present three cases of herpes virus infections in immunocompetent patients: one of the infections was herpes simplex 1 in a 40-year-old woman, and the other two were herpes varicella-zoster infections in a 62-year-old man and a 25-year-old woman. The patients were in the care of the southern health district of Seville of the SAS (Andalusian Health Service) during the Spanish state of alarm over the COVID-19 pandemic. The SARS-CoV-2 infection was confirmed in only one of the three cases. In this study, we briefly review the etiopathogenic role of the COVID-19 pandemic situation, whereby immunodeficiencies are generated that favour the appearance of other viral infections, such as herpes virus infections.
