The first cases were seen in Wuhan City of Hubei Province China in December 2019, and have been linked to the Huanan Seafood Market (South China) and the infection has spread to several countries around the world.4 The recombination of DNA was found to be involved at spike glycoprotein which assorted SARS- CoV (CoVZXC21 or CoVZC45) with the RBD of another Beta CoV, thus could be the reason for crossspecies transmission and rapid infection.5 The virus that causes coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection and mainly transmitted through contact with respiratory droplets rather than through the air. Higher-throughput It has become the preferred method.12 Average sensitivity for rapid molecular tests were 95.2% (ranging from 68% to 100%) and average specificity was 98.9% (ranging from 92% to 100%) between test results of different company brands and sampling methods15 Samples can be obtained by various methods, including a nasopharyngeal swab, sputum (coughed up material) throat swabs, deep airway material collected via suction catheter16 or saliva.
