One thing is certain: COVID-19 affects people in different ways. The majority will experience mild to moderate symptoms, including a fever, a dry cough, and tiredness. Some will also have muscular aches and pains, a sore throat, a stomach upset, headaches, conjunctivitis, the loss of taste or smell, or a skin rash. An unfortunate one in five COVID-19 patients will develop more serious symptoms, including difficulty breathing, chest pain, loss of muscle control, severe inflammation, and organ damage.
