The coronavirus vaccines are here and with them comes a feeling of hope—and a renewed sense of caution. It would be terrible to get COVID-19 just as we near the finish line. Besides the symptoms you’ve heard of from the CDC—fever, chills, cough, shortness of breath, etc.—there are new ones popping up, including some within the last month. Read on for the latest symptoms doctors have discovered—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus.

“Seeing increasing numbers of Covid tongues and strange mouth ulcers. If you have a strange symptom or even just headache and fatigue stay at home!” tweeted Tim Spector, a professor of genetic epidemiology at King’s College London. “My mail is full of tongues each morning from people who had tongue problems that coincided with Covid symptoms like fever and fatigue – but baffled doctors. Happy to share so we all become experts …” he tweeted.

You might see a sudden appearance of raised bumps on the skin which come and go quite quickly over hours and are usually very itchy. It can involve any part of the body, and often starts with intense itching of the palms or soles, and can cause swelling of the lips and eyelids. These rashes can present quite early on in the infection, but can also last a long time afterwards.

Andrew Chan, a professor of immunology and infectious disease at the Harvard T.H. Chan School of Public Health and co-founder of the COVID Symptom Study app, whose data is being used by researchers around the world, claims that it has been detecting more cases of raised skin bumps and inflammation on fingers and toes—aka COVID fingers and toes—and that it should be considered a key diagnostic sign of the disease. In fact, many people are experiencing these strange dermatological manifestations in the absence of any other symptoms.

“Covid-19 can lead to abnormal blood clotting. Those clots can then choke off blood vessels, impairing the function of other organs like the liver or kidneys. Some of these effects can take weeks to manifest,” says Vox.

Long COVID is, unfortunately, nothing new—it's a series of symptoms that last long after “long haulers” have COVID, and may never go away. But Dr. Anthony Fauci, the chief medical advisor to the President and the director of the National Institute of Allergy and Infectious Diseases, did recently give it a name: post-acute sequelae SARS-CoV-2 infection (PASC). He also announced $1.15 billion in funding to study PASC, which can result in fatigue, migraines, post-exertional malaise and some of 98 symptoms or more. If you experience PASC or any of the symptoms mentioned here, contact a medical professional immediately.
