COVID-19 and Herpes Simplex Virus Infection: A Cross-Sectional Study
Abstract
Background
Despite being variable and poorly characterized, the reported cutaneous manifestations of COVID-19 are of increasing concern.
Aim of the Study
This study aimed to assess the prevalence and possible association between COVID-19 and herpes simplex virus (HSV) infection.
Patients and methods
A 9-item questionnaire was sent to 120 PCR-confirmed COVID-19 patients with a response rate of 66.67%. This cross-sectional observational study included 80 patients with mild to moderate COVID-19 infection who did not require hospitalization or steroid therapy.
Results
One or more HSV infections were observed in 28 patients (35%) with COVID-19 infection, including 10 males (35.7%) and 18 females (64.29%). Of the 28 patients, fever was reported in 17 patients (75%) during COVID-19. Most of the respondents (78%) described a single HSV reactivation, 14.29% had 2 attacks, and 7.14% experienced 3 attacks. Compared to previous non-COVID-19 related HSV reactivation, the COVID-19 related attacks were more severe in 12 patients (42.85%), equally severe in 5 patients (17.85%) and less severe in 1 patient (3.57%). Interestingly, 10 patients (35.71%) developed an initial symptomatic HSV attack during COVID-19 infection.
Conclusions
This study demonstrated a possible association between COVID-19 infection and primary HSV infection and/or reactivation. The COVID-19 direct neuronal effect in addition to COVID-19 related psychological stress, fever and immunological dysregulation could play a potential role.
