According to the CDC, the symptoms of COVID-19 infection can include: • Fever • Dry cough • Shortness of breath • Muscle pain • Headache • Sore throat • A loss of smell or taste • Chills or shaking with chills If you have a healthy immune system, then these symptoms will almost certainly not be serious for you. A person with a compromised or underdeveloped immune system, however, could be at great risk and even risk of death. Also, older patients have this kind of risk.
