A cross-sectional questionnaire study in a phototherapy unit during COVID-19.

Background: In March 2020, social isolation measures were imposed in Brazil to contain the spread of the novel coronavirus (SARS-CoV-2), requiring health services to implement contingency plans. The main objective of the study was to verify the status of the disease, self-reported by patients who discontinued phototherapy, during a period of social isolation.

Methods: All patients receiving phototherapy at the Santa Casa de Porto Alegre, Brazil, prior to the implementation of social distancing measures were eligible for inclusion in the study.
