There is no such thing as seven days of symptoms of coronavirus in clinical practice. Coronavirus refers to a new type of coronavirus, which is characterized by fever and respiratory symptoms that can get progressively worse, and in some patients, chest tightness, sore throat, muscle aches and diarrhea. Infection with coronavirus disease can cause fever, dry cough and malaise. In a few patients, it is accompanied by nasal congestion, runny nose, sore throat, muscle pain and diarrhea. Severe patients usually develop respiratory distress and hypoxemia about a week after the onset of the disease, and severe cases can rapidly progress to acute respiratory distress syndrome. Coronavirus disease is a highly contagious respiratory infection. Therefore, if you are infected with coronavirus disease and have relevant clinical symptoms, you should seek medical advice and take appropriate isolation measures.
