COVID toes refers to the high prevalence of chilblains of the toes in those with COVID-19.
COVID toes, also known as COVID-19 toe lesions or pernio-like lesions, are skin manifestations that have been observed in some individuals infected with the SARS-CoV-2 virus, which causes COVID-19. These skin changes typically appear as red or purple discoloration, swelling, and sometimes blisters or ulcers on the toes or fingers.
COVID toes are considered a dermatologic symptom associated with COVID-19, but they are not exclusive to the disease and can occur in other conditions as well. They have been observed more commonly in younger individuals, including children and adolescents, but can also occur in adults.
The exact cause of COVID toes is not yet fully understood. However, it is believed to be related to inflammation and the immune response triggered by the viral infection. The small blood vessels in the toes or fingers may become inflamed, leading to the characteristic discoloration and other skin changes.
COVID toes are typically a mild and self-limiting condition, and most individuals with these skin manifestations do not experience severe symptoms or complications. The skin changes tend to resolve on their own over time without specific treatment.
COVID toes may occur in conjunction with other symptoms of COVID-19 or even before other symptoms appear. However, they can also be an isolated finding without other significant COVID-19 symptoms.
