Development of chilblain lesions during the COVID-19 pandemic is strongly associated with cold weather: a retrospective analysis of patients from a single centre in the USA

Clin Exp Dermatol. 2024 Feb 14;49(3):284-286. doi: 10.1093/ced/llad396.

Abstract

This study aimed to retrospectively investigate the association between chilblain lesions and SARS-CoV-2 infection. Our results demonstrate a stronger and more significant association between incidence of chilblain cases and monthly temperature compared with incidence of SARS-CoV-2 infection. These results suggest cold weather was an important risk factor for developing chilblains during the COVID-19 pandemic.
