Herpes zoster in post-covid era: a case study

Herpes Zoster is a manifest disease caused by the reactivation of the type 3 herpes virus Varicella Zoster as a result of immunological or hormonal stress. Since 2021, the Russian Federation has a stable tendency to increase of Varicella incidence due to the beginning of a new long-term epidemic cycle. Since Herpes Zoster is secondary to Varicella, the recurrent form of infection has been subject to statistical monitoring in the Russian Federation since 2019. The analysis of the data obtained shows that Herpes Zoster is present in all age groups, including infants, and its incidence increases with age. The increase of Herpes Zoster incidence is caused not merely by the rise of Varicella, but also with the recent Covid-19 pandemia, since adults who have experienced a new coronaviral infection are more likely to catch Herpes Zoster. The article provides a clinical case of Herpes Zoster that developed in a 5-year-old child as a result of maternal Varicella at 30 weeks pregnant.
