Sure Signs You've Had COVID Already, According to a Doctor

You may have battled the virus without knowing it.

You may already know that you had COVID-19 because you tested positive for the virus. However, one of the biggest issues in slowing the spread of COVID-19 is that the highly infectious virus can be very difficult to identify. In fact, some people who are infected, never experience any symptoms. Therefore, there are likely a lot of people who already had it and didn't even know. Unfortunately, even those people who fall into the latter category aren't immune from what experts are referring to as long COVID or "long hauler symptoms," a prolonged set of symptoms linked to an initial infection. Shirin Peters, MD, Founder of the Bethany Medical Clinic in New York, explains to Eat This, Not That! Health that if you have experienced any of the symptoms you're about to read about for the first time after March 2020, you could have already had COVID. Read on—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus


You Have Persistent Shortness of Breath

Many people infected with COVID-19 experience shortness of breath as an initial symptom. However, it can also linger for many months after. Dr. Peters explains the symptom as "feeling like you can't catch your breath or get easily winded with minimal exertion."


You Have a Loss of Certain Senses

Are you having trouble smelling things or tasting food? Loss of sense of taste or smell is another symptom that many patients report as an initial symptom, but it can also linger for several months. "This can present as decreased appetite," Dr. Peters adds. 


You Have Extreme Fatigue

So, how can you tell if you need to worry about your excessive tiredness? "Feeling tired after a full 8 hours of sleep is a sign that you have a health problem," Dr. Peters points out.
