Novel coronavirus has an incubation period, so it is not easy to check and confirm the diagnosis. Its incubation period is usually 3-7 days, and the longest is not more than 14 days, so within 14 days, if you have been in contact with a confirmed or suspected novel coronavirus infection, or have been to an infected area and have symptoms such as fever, malaise, dry cough or dizziness or chest tightness, you need to go to the infectious disease department or fever clinic of a hospital for examination to clarify the diagnosis.
Of course not all symptoms of fever, dry cough and malaise are caused by novel virus infection, but it may also be just a common cold, and a chest CT or novel coronavirus nucleic acid test can be done to clarify the diagnosis.
