Materi genetik virus yang dideteksi yaitu pada gen E, open reading frame (ORF), RNA-dependent RNA polymerase (RdRp), gen N, serta gen S. Cycle threshold (CT) secara sederhana merupakanjumlahsiklus yang dapat mendeteksi materi genetik pada virus.
ORF1a is the first open reading frame at the 5' end of the genome. Together ORF1ab occupies about two thirds of the genome, with the remaining third at the 3' end encoding the structural proteins and accessory proteins. It is translated from a 5' capped RNA by cap-dependent translation.
