A change in tongue appearance is one of the newest mouth-related symptoms being reported. Tim Spector, PhD, an epidemiologist and principal investigator for the ZOE COVID Symptom Study app, tweeted out a picture of a patient with a white tongue that resembles a condition called geographic tongue. Spector indicated that this “COVID tongue” may be one of the “less common symptoms” patients experience that don’t get included on official public health lists. According to the Mayo Clinic, geographic tongue is an inflammatory condition, which may indicate its relationship to the coronavirus. An Aug. 2020 study published in the International Journal of Infectious Diseases said that when cells with ACE2 receptors become infected with the virus, that can cause inflammatory reactions in related organs and tissues, such as the tongue.

Skin rashes have been heavily documented as a coronavirus symptom, but you may also experience a mouth rash. According to WebMD, a Spanish study published in the journal JAMA Dermatology was the first to identify this symptom, called enanthem, which presents as rashes or ulcers in the mouth. In the study, enanthem usually appeared anywhere from two days before the onset of other coronavirus symptoms to 24 days after. Michele Green, MD, a dermatologist at Lenox Hill Hospital in New York City, told WebMD that enanthem is not a surprising symptom for the coronavirus, given how it arises in other infections. “It is very common in patients with viral infections like chickenpox and hand, foot and mouth disease. It is characteristic of many viral rashes to affect mucous membranes,” she explained. And for more coronavirus news, Dr. Fauci Just Issued This Stern Warning About the U.K. COVID Strain. A Dec. 2020 study published in the Neurology Clinical Practice found that 62.4 percent of coronavirus cases had symptoms of dysgeusia, which is a distortion of the sense of taste. And while many people know that loss of taste is a coronavirus symptom, they may not realize it could first appear as a metallic taste in their mouth. Robert Korn, MD, an emergency medicine physician in New York, told Refinery29 that a metallic taste in your mouth could possibly just be “an altered taste on the way to losing the sensation completely.” And for more up-to-date information, sign up for our daily newsletter. A Sept. 2020 study in the Ear, Nose & Throat Journal concluded that dry mouth, otherwise known as xerostomia, should be considered a symptom of the coronavirus. Researchers noted that various studies had determined that salivary glands had the highest existence of ACE2 receptors in the cells—and those receptors are what allows the virus to enter someone’s body. Given that reduced or absent saliva flow can be caused by viral-induced infections and inflammation, the researchers concluded that dry mouth could result from a COVID infection.
