Rare Symptoms of COVID You Might Miss

These lesser-known physical signs can be red flags for coronavirus.

We know to be alert for the most common COVID-19 symptoms: Cough, fever, trouble breathing. But the coronavirus has been found to affect nearly every part of the body, and the first sign of your infection can be a pretty obscure one (or you could have no coronavirus symptoms at all). In fact, one recent study found a number of issues might even last long after the virus has left you, including irregular menstruation, bad moods, temperature fluctuations and other problems you might not associate with COVID-19 but should. Read on to discover five rare symptoms of COVID you might miss—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus.


You Might Have Skin Problems


You might remember the recent splash of headlines about "COVID toes," one of the most unusual symptoms of coronavirus. About 20% of people with COVID-19 report skin changes, such as a red, bumpy rash; hives; or breakouts resembling chickenpox. Some people—generally young and previously healthy—have reported rashes on their toes, which can last up to five months.


You Might Have Eye Problems

In some people, coronavirus is accompanied by eye issues, including dry, red, or itchy eyes, conjunctivitis (pinkeye), enlarged blood vessels, swollen eyelids, excessive watering and increased discharge. A study in JAMA Ophthalmology found that nearly one-third of hospitalized COVID-19 patients reported eye problems.
