⏩ ‘COVID toes’: A sign your kids might have coronavirus.

Add “skin” to the everlonger list of parts of a person’s body that could be affected by the contagious respiratory illness COVID-19.

Though it hasn’t made the Centers for Disease Control and Prevention’s list of COVID-19 symptoms, dermatologists and infectious disease experts said some people infected with the coronavirus might develop a skin rash — which can resemble the measles or chicken pox — or a discoloration to the feet, which appears like a bad case of frostbite.

It’s the latter condition that’s gotten the most notoriety, gaining the moniker “COVID toes.”

“It’s sort of the body’s response manifested in the skin,” said Dr. Zane Saul, chief of infectious disease at Bridgeport Hospital.

The American Academy of Dermatologists is starting to research these dermatological symptoms, and is asking health care professionals to fill out a registry if a COVID-19 patient develops skin symptoms, or if someone with a dermatological condition develops COVID-19.

Though it’s not entirely known what’s causing the skin symptoms, Saul said it isn’t a surprise that the virus has some dermatological impacts.

“We know that viruses cause all kinds of rashes. And chicken pox and measles are themselves caused by viruses,” he said.

As for what’s causing the purple discoloration marked by so-called COVID toes, that’s also being examined. It could be caused by small blood vessels clotting, said Dr. Paul Nee, an infectious disease physician at Danbury Hospital.

However, he said, “it’s still unclear.”

“I would say as we get more into the pandemic, we’ll learn more about the manifestations,” Nee said. “Every week, we’re learning something new about this.”

Dr. Frank Santoro, chief of dermatology at Hartford Hospital, said problems with the toes can be signs of a blood clot, and blood clots have led to the deaths of many COVID-19 patients. However, he doesn’t think COVID-19 is a harbinger of serious blood clots.

In fact, he and other experts said most patients who get COVID toes, in particular, don’t usually have other symptoms or they are typically mild.

Santoro said most patients who get the dermatological symptoms are young, and it usually happens near the end of the infection. “It seems to be a low-risk sign of infection,” he said.

Saul echoed those statements. “I have heard of a couple of people — mostly young adults — where the only manifestation is in the toes,” he said. “You sort of ride it out and monitor yourself for other symptoms you might have.”

Those who get a rash should consult a physician, particularly if they are in a high-risk job or have been in contact with someone with COVID-19.

“And if you do get other symptoms, you might want to seek medical attention,” Saul said.
