The self-test for new coronavirus pneumonia is as follows: 1) having symptoms such as fever, malaise, cough, and difficulty breathing; 2) special populations, such as having a runny nose, sore throat, or diarrhea, because some patients do not develop fever, so fever is not the only symptom; 3) whether you have been in and out of infected areas, and confirm whether you have been in and out of areas with a high incidence of the disease; 4) determining whether you have been in contact with others and themselves at some point in time and have had contact with the crowd. Through self-assessment in these areas, it is possible to clarify whether you have a history of exposure and determine whether you have a new crown infection. Content source: Dr. You Lai
