How do you know if you've already had coronavirus? As a doctor, I am asked this often. Although there are numerous symptoms of COVID, many of these, such as fever, can occur from numerous infections. Plus, an estimated 40-45% of patients are asymptomatic and may not feel anything. But if you had a severe, dry cough and shortness of breath, these are most suggestive of coronavirus. Cough and shortness of breath occur because of the virus infecting the lungs. Of course, the best way to know for sure if to get tested and quarantine until you have the result, but other signs you've already had coronavirus—or have Post-COVID Syndrome, which can last for months after infection—include the following. Read on, and to ensure your health and the health of others, don't miss these 35 Places You're Most Likely to Catch COVID.
Fatigue

You'll feel this as your body diverts energy production to fighting the infection.
Fever

A fever occurs as the body tries to make the local temperature inhospitable to the virus.
"Brain Fog"

Dr. Anthony Fauci has called this "difficulty in concentrating" or a sudden "confusion." It is common with numerous infections as your body produces interferon and because of toxins from the infections (and numerous other causes).
Sore Throat

You might experience this because of the virus infecting the throat.
Nausea and Diarrhea

The virus can also infect the stomach and intestines.

You Might Have Post-COVID Syndrome

Post-COVID Syndrome is when you have persistent symptoms of fatigue, insomnia, brain fog, cough, and shortness of breath more than three weeks after the infection. Other symptoms can also be present, but these are the most important. (Specific injury to the lungs, brain, and heart also contributes to symptoms.) Dr. Fauci has correctly noted that this represents post-viral chronic fatigue syndrome. This is when a severe energy crisis causes people to trip an almond sized circuit breaker in the brain called the hypothalamus. This results in inability to sleep, widespread hormonal deficiencies, brain fog, fatigue, and your brain not getting enough blood when you stand.
Is There a Cure for Post-Viral Syndrome?

I had post-viral chronic fatigue syndrome in 1975. It knocked me out of medical school and left me homeless for a year. Once I learned how to recover, I spent the next 45 years researching and developing effective treatment for post-viral chronic fatigue syndrome.
Numerous studies are underway trying to understand the causes of post-COVID syndrome. But the good news is that post-viral chronic fatigue syndrome, and persistent post-COVID symptoms, are very treatable. Our published placebo-controlled study showed that SHINE (optimizing Sleep, Hormones, Immunity, Nutrition, and Exercise as able) resulted in an average 90% increase in quality of life, making this very treatable. I feel post-COVID can be effectively treated and now. The problem is not lack of effective treatments, but rather lack of effective physician education. Discuss Post-COVID Syndrome with your doctor—or a post-viral specialist like me—and to get through this pandemic at your healthiest, don't miss the comprehensive list of the Sure Signs You've Already Had Coronavirus.
