If You Have This Subtle Symptom, You Might Have Already Had COVID

If you've been feeling out of it lately, you might have had COVID without realizing it.

COVID can come with a myriad of symptoms or none at all. And if you were asymptomatic or had minimal symptoms, it's possible that you had the virus without even realizing it. But even without exhibiting symptoms, COVID can affect your body long after you're contagious. And if you've felt abnormally tired lately, you may have already had COVID. It's easy to assume your tiredness is a result of poor sleep, a busy schedule, or early nightfall. However, with COVID in the mix, you should consider the possibility that your fatigue is related to the virus. Here are the signs your fatigue could mean you've had COVID, and to see if you have this super subtle COVID symptom, check out This Is One of the Most "Easily Overlooked" COVID Symptoms, Experts Warn.

Your exhaustion isn't relieved by sleep.

Some COVID patients experience post-viral syndrome, which can occur with other viruses too, where you're technically no longer sick, but the virus continues to wreak havoc on your body. And one of the key symptoms of post-viral syndrome is fatigue.

Leann Poston, MD, a licensed physician and health advisor for Invigor Medical, says post-viral syndrome is characterized by "persistent fatigue" and "exhaustion that is not relieved by sleep."

"Inflammation of the hypothalamus, a part of the brain that regulates many bodily functions such as sleep, appetite, body temperature, and hormone release, leads to the severe fatigue that people with prolonged symptoms of COVID are reporting," says Poston.

You get tired from minimal physical or mental activity.

If sleep doesn't make you feel better, there are a few other ways to assess the potential that your fatigue is related to COVID. Chiropractic neurologist Tatiana Habanova, DC, says there are two questions you should ask yourself: "Do you now get unusually tired from minimal physical activity? Do you now get unusually tired from minimal mental activity (thinking, focusing, concentrating, etc.)?" If the answer to either of those questions is yes, you may have silently battled COVID.

You also have brain fog or difficulty concentrating.

Poston also pointed out that "difficulty concentrating and brain fog" tend to go hand-in-hand with the fatigue that accompanies post-viral syndrome. Family medicine physician Abisola Olulade, MD, says patients often "feel they cannot think clearly and as if they are stuck in a fog."

In July, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases (NIAID), warned about these symptoms of post-viral syndrome during the International AIDS Conference, saying that some people who had COVID were experiencing "brain fog, fatigue, and difficulty in concentrating" even after the virus dissipated.

Olulade says to look out for other aspects of post-viral syndrome including "persistent unexplained fever, trouble concentrating or paying attention, memory issues, muscle aches/pains, problems sleeping, dizziness, feeling lightheaded or weak, headaches, depression, and anxiety." Poston also says that muscle aches and depressive symptoms are key signs of post-viral syndrome and if you've experienced any of these issues with your fatigue, you may have had COVID.
