Incidence of skin diseases in healthcare workers before and during the COVID-19 pandemic at Trieste hospitals (northeastern Italy).

Incidence of OSDs was a little bit higher during the COVID-19 pandemic compared to the previous period but fluctuation of numbers were mainly related to calendar period, with higher incidence in winter and spring. Incidence data were higher than that observed in 2004-2013 in the same cohort. Face dermatitis cases doubled after the start of COVID-19 pandemic. Overall data demonstrated a non-significant increase of OSDs in HCWs during the pandemic, probably due to the preventive strategies set up in our cohort over the years.
