In the beginning days of the pandemic, there was a focus on three main signs of COVID-19: fever, cough, and shortness of breath. But as experts began to understand the disease better, it became clear that many health changes could indicate someone has the virus—loss of taste or smell, diarrhea, and headache, just to name a few. The Centers for Disease Control and Prevention (CDC) lists many symptoms that may signal a COVID-19 infection. The list is not exhaustive, though, and the CDC says it will continue to update the list as they learn more about the disease.
Skin rashes are a potential sign of COVID-19 that weren't originally included on the list.

11 Coronavirus Symptoms You Need to Know—and How to Prevent the Virus
According to a 2021 study published in the British Journal of Dermatology, there is an association between skin rashes and a positive COVID-19 swab test result. Researchers determined that by looking at information from 336,847 people in the UK who had uploaded their health history, including any COVID-19 test results and symptoms, to the COVID Symptom Study app. The app data showed that, among those who had a positive swab test result, 8.8% also reported skin-related changes. And of those, 6.8% reported body rashes and 3.1% acral rashes (an acral rash is a rash on the extremities).
To better understand the length and timing of these skin symptoms, the researchers then looked at the results of an independent survey on skin symptoms related to COVID-19 that 11,544 people had completed.
The skin changes appeared at the same time as other COVID‐19 symptoms for 47% of the survey respondents and after other COVID-19 symptoms for 35% of the survey respondents. But what the researchers found to be most striking was that 17% of the respondents said that their skin changes happened before any other COVID-19 symptoms. And 21% of the people said that their rash was the only symptom of COVID-19 they experienced.
The researchers said that their "study strongly supports the inclusion of skin rashes in the list of suspicious COVID‐19 symptoms." And while rashes might be less common than other signs of COVID-19, the study authors point out that skin changes can be easily recognized, which may help with virus detection and contact tracing.
Does Coronavirus Cause a Rash? What You Need to Know
To help people identify what a COVID-19 rash might look like, and using the pictures that the survey respondents had submitted, the researchers worked with the British Association of Dermatologists (BAD) to create a catalog of images of the most common skin manifestations of COVID‐19. The rash pictures are divided into these main categories:
COVID Digits
covid-rash
BRITISH ASSOCIATION OF DERMATOLOGISTS
According to the BAD, since they don't look like any other skin condition, COVID toes and fingers—aka digits—might be the most telltale COVID rash.
At the beginning of the pandemic when dermatologists started seeing more cases of what appeared to be chilblains—a skin condition that typically occurs during colder months—in warmer months, many took note and questioned whether it was chilblains. The link with COVID-19 was eventually made and the chilblain-like rash was coined COVID toes.
"The rash appears as reddish and purplish bumps on the fingers or toes and can affect many digits," per the BAD. "The fingers and toes are usually sore, but not itchy." As the rash heals, the top layers of the skin may peel away from where the purplish bumps were, leaving scaly patches.
Dermatologist Veronique Bataille, MD, PhD, and researcher Mario Falchi, PhD—two of the study's authors whose work helped build the image catalog—told Health that COVID digits can happen months after the initial infection and are more common in young people who may have been asymptomatic.

Neck and Exposed Chest Eczema
This rash appears on the neck and on the part of the chest that is exposed to sunlight. Usually, the rash is itchy. It can look pink on lighter skin; on brown or black skin, eczema tends to look darker brown, purple, or gray. It can appear during or after the infection and typically lasts for an extended period. And according to Dr. Bataille, a patient doesn't have to have a history of eczema for this type of rash to develop. Most patients included in the survey had no history of skin conditions.
Oral Rash
With this rash, a person's lips may feel sore. As the rash subsides, the lips can become dry and scaly. The BAD reported that soreness inside the mouth could also occur.
