Mouth lesions and spots on the palate may be a new symptom of the novel coronavirus, a new study suggests.
Researchers found that one-third of COVID-19 patients with skin rashes on their arms and legs also had breakouts on the roofs of their mouths.
What’s more, these splotches usually appeared about two weeks after people first experienced more well-known symptoms such as fever or shortness of breath.
The team from Ramon y Cajal University Hospital in Madrid, Spain, says doctors and nurses should examine the oral cavities of confirmed or suspected coronavirus patients to see if they are also exhibiting these signs.
At the onset of the pandemic, the Centers for Disease Control and Prevention recorded just three symptoms of the virus on its website: fever, cough and shortness of breath.
However, in April, the federal health agency expanded its list to include several more signs of infection including chills, repeated shaking with chills, muscle pain, headache, sore throat and new loss of taste or smell.
Health officials have said that as more is learned about the new virus, new symptoms may also emerge.
For the study, published in JAMA Dermatology, the team looked at 21 coronavirus patients a hospital who had a skin rash from March 30 to April 8.
Six patients had enanthem, which is a rash that looks like small spots that typically appear in the mucous membranes, such as the mouth, nose and throat.
