Since the COVID-19 pandemic began, the virus has caused various symptoms beyond the commonly known fever, cough, and fatigue. One lesser-known symptom that has emerged is “COVID toes,” characterized by frostbite-like lesions on the toes and sometimes fingers. This article explores the symptoms, treatments, and preventive measures related to COVID toes, highlighting the importance of foot health during and after the pandemic.
1. Symptom of “COVID toes”
Since the pandemic’s start, people worldwide have reported red, inflamed lesions resembling frostbite on their toes and occasionally fingers. Initially, many health professionals were unaware of their link to COVID-19 due to negative viral tests in these patients. However, an April 2020 study by dermatologist Thierry Passeron and colleagues from Nice University Hospital found that all 40 patients studied developed COVID-19 within three weeks prior to lesion appearance.
Unlike generalized skin reactions seen after respiratory infections, “COVID toes” represent a unique, localized response related to a heightened innate immune system. Innate immunity includes the body’s first defense barriers such as skin and mucous membranes, along with cellular components that prevent pathogen spread.
2. Treating COVID foot symptoms
Though uncomfortable, “COVID toes” typically indicate a strong immune response and infection nearing resolution. Symptoms include swelling and purplish discoloration of one or multiple toes. Recovery generally occurs within weeks without lasting effects.
The exact cause of these lesions remains uncertain. Some scientists hypothesize viral replication within the skin, but firm evidence is lacking due to limited studies.
3. Preventing foot injuries
The pandemic has altered lifestyles, including widespread working from home, which often entails less footwear use during the day. While comfortable, going barefoot or in socks may pose health risks, especially for individuals with foot pain, poor circulation, or chronic conditions like diabetes.
Wearing well-fitting shoes that provide good arch support is essential to avoid foot injuries. Additionally, stretching and walking short distances during the day improve blood circulation and reduce risks of complications.
Since toe inflammation can cause various discomforts, anyone experiencing pain should consult a podiatrist, such as those at PiedRéseau, for professional diagnosis and treatment options. Because COVID toes may not be easily distinguished from other causes, a medical evaluation is always recommended.
