Abstract
In Wuhan, China (December 2019), viral pneumonia cases of uncertain origin have been reported. The emergency has drawn global attention. To determine the pathogenic potential, joint efforts were conducted by Chinese Multidisciplinary Task Forces. An integral component of wide range of research applications is not only determining the causative agent but also the nucleic acid bases order in biological samples. Research techniques determining genetic material features and its order is called “sequencing”, classified into three generations. Moreover, the first sequencing attempt was conducted and a genetic link identified between samples isolated from China and other previously sequenced Coronaviruses. However, there was patient to patient diversity in terms of clinical and laboratory manifestations and diseases severity. After the genetic material of the causative agent was successfully sequenced, it was named the novel coronavirus causing COVID-19. Here, we review the genome sequences of novel coronavirus infected patients from different countries such as India, Bangladesh and Ecuador compared to China (first reported case), seeking not only to recognize similarities and differences between genome sequences of novel coronavirus, but also to compare them with other forms of coronaviruses family. Utilizing this data will assist in making right decisions minimizing negative consequences of the outbreak.
