The symptoms of a dry cough caused by a novel coronavirus infection are not very different from those of a common cold. Therefore, if you find yourself with frequent dry cough, do not be overly nervous, but calmly recall if you have been in contact with a patient infected with novel coronavirus or have been to an area with severe outbreak of novel coronavirus within the previous 14 days. If you have, please isolate yourself and seek medical attention as soon as possible; if not, you should first isolate yourself at home to ensure the safety of those around you. After 14 days of isolation, if no obvious symptoms appear, you can basically rule out the possibility of being infected by novel coronavirus.
