Relative changes in the pattern of diseases presenting in dermatology outpatient clinic in the era of the COVID-19 pandemic

Abstract

As an increasing number of COVID-19 cases, there were changes in the number of patients who attended the dermatology outpatient clinics. We aimed to investigate the change profiles of dermatologic diseases in the first and second months of the COVID-19 pandemic in Turkey by comparing with the corresponding period of the previous year. The total number and diagnosis of patients, who attended a tertiary care hospital for the dermatology outpatient clinic between 1 April 2020 and 31 May 2020, were included in this study. These data were compared with the corresponding period of the previous year. The percentage of the patients with scabies, contact dermatitis, psoriasis, pityriasis rosea, urticaria, and alopecia areata were statistically significantly increased a month after the occurrence of the COVID-19 pandemic, while the percentage of patients with scabies, alopecia areata, telogen effluvium, acne vulgaris, and xerosis cutis were statistically significantly increased 2 months after the occurrence of the COVID-19 pandemic (P < 0.05). An increase in the number of certain diseases such as urticaria and pityriasis rosea may indicate the risk of asymptomatic COVID-19 carriage in these patients. Polymerase chain reaction (PCR) and/or antibody-based further studies should be performed to explore whether certain dermatologic diseases are related to asymptomatic COVID-19 cases.
