Abstract

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first isolated from Wuhan from three patients with pneumonia. Afterwards the disease spread all over the world with high spreading rate. SARS-CoV-2 is closely related to the original SARS-CoV and it has all the features of the related coronaviruses in nature. As there is no vaccine provided yet, early diagnosis is very important for prompt management and to prevent the spread of highly contagious global pandemic. Currently nucleic acid amplification test, real-time reverse transcriptase PCR (RT-PCR) is used for diagnosis. Genes like E, N, S or ORF are targeted for screening or diagnosis. Serological assays are used for epidemiological studies and for identifying population at high risk for infection, while point of care molecular tests have the advantage of rapid, accurate and low cost which provide great help in diagnosis and quarantine of infected patients.
