If a novel coronavirus infection is detected, the first signs are fever, dry cough or generalized fatigue. However, it is possible to be alerted to new coronavirus infection earlier, for example, if someone around you has symptoms, or after traveling to an infected area or coming into contact with people who have returned from an infected area, you should pay attention to the symptoms, dizziness, drowsiness, and take precautionary measures in time. If there is fever, respiratory symptoms, and generalized weakness, you can go to a designated hospital for screening and timely detection of the disease. Source: Dr. Yurai
