Cutaneous eruption in COVID-19-infected patients in Thailand: An observational descriptive study.

Coronavirus disease 2019 (COVID-19) emerged in Thailand in January 2020. Thailand was the first to report a confirmed case outside China. Cutaneous eruption in COVID-19 has been reported since the disease became pandemic but limited in tropical countries such as Thailand. The aim of this study was to observe the incidence, characteristics and relation of cutaneous eruption with COVID-19 at Bamrasnaradura Infectious Diseases Institute, a referral center of emerging infectious diseases in Thailand. An observational descriptive study observed the incidence and characteristics of cutaneous eruption in 204 COVID-19-infected patients at Bamrasnaradura Infectious Diseases Institute. We report five patients, who represented six incidences of skin eruption with four characteristics: maculopapular rash (50%), acute generalized exanthematous pustulosis (16.67%), Stevens-Johnson syndrome (16.67%) and urticarial vasculitis (16.67%). Incidences of cutaneous eruption in COVID-19 at Bamrasnaradura Infectious Diseases Institute were low. Most of the incidents were associated with medication used to treat COVID-19 infection, so drug allergy cannot be excluded as a cause of the rashes. Therefore, drug allergy should always be ruled out, and skin manifestation in COVID-19-infected patients should be further observed.
