Novel coronaviruses are RNA viruses, a type of coronavirus whose structure consists mainly of a single strand of RNA inside a single strand of ribonucleic acid, surrounded by a protein. If the virus is tested, the most specific feature of the virus can be found, which is hidden in its nucleic acid and is the most reliable basis for confirming the diagnosis of novel coronavirus infection. Therefore, through special methods, including PCR, it is possible to detect the unique characteristics of the novel coronavirus and to prove more reliably that the infecting pathogen is the novel coronavirus, which is the main purpose of nucleic acid testing of patients.
