Background Information for SARS-CoV-2 Detection

Coronavirus diseases 2019 (COVID-19) is a highly infectious and an emerging respiratory disease caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 has a nonsegmented, linear, positive-sense, multicistronic genome and produces enveloped virions. The virus is classified as a betacoronavirus (Nidovirales: Coronaviridae) together with the other 2 highly virulent human pathogens severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). The SARS-CoV-2 genome shares 79.6% and 50.0% nucleotide sequence identity with the genomes of SARS-CoV and MERS-CoV, respectively. Similar to SARS-CoV, SARS-CoV-2 virions use their spike (S) glycoproteins to engage host-cell angiotensin I–converting enzyme 2 (ACE2) to gain entry into host cells and host-cell transmembrane serine protease 2 (TMPRSS2) for S priming.

 

Diagnostics can play an important role in the containment of COVID-19, enabling rapid implementation of control measures that limit the spread through case identification, isolation, and contact tracing (i.e., identifying people that may have come in contact with an infected patient). Molecular techniques are more suitable for accurate diagnoses because they can target and identify specific pathogens. The most commonly used targets for primer/probe development in case of SARS-CoV-2 are from conserved viral genome including ORF1ab gene, RdRP gene (RNA dependent RNA polymerase), N gene (Nucleopcapsid) and E gene (Envelope). Real-time reverse transcription-polymerase chain reaction (qRT-PCR) of upper respiratory specimens, such as nasopharyngeal swabs and pharyngeal swabs, has been widely used to confirm the clinical diagnosis of COVID-19.
