COVID-19 disease occurs in the form of a respiratory infection with fever, cough, fatigue, and difficulty breathing. To the best of our knowledge, 80% of the infection is asymptomatic or mild. The disease carries a higher risk in old age with other associated diseases (diabetes, hypertension, cardiovascular disease), but young people and those living a sporty lifestyle may experience prolonged or even severe symptoms. Even after an illness with asymptomatic or mild symptoms, organ changes can be developed, so you should only gradually return to your previous lifestyle and exercise.
