Abstract: A pneumonia or respiratory illness of unknown source was detected in China during the late 2019,[2] that was identified afterward as a positive-sense single-stranded RNA genomic material called SARS-CoV-2. World Health Organization (WHO) declared that as nCoV- 19 or COVID-19. The person to person transmission of the virus is rapid by close contact and droplets produced when infected patients talk, sneeze or cough. The virus may also be transferred by touching the contaminated surfaces followed by contacting the nose, mouth or eyes.
