The Severe acute respiratory was found in 2003 when it first hit China and caused a big outbreak. Studies have shown that SARS-CoV originated in bats and cats. Recent metagenomic studies of bats viruses identified several SARS-CoV DNA sequences that are at least 90% identical to the SARS virus. In the end of 2002, the only known coronavirus was to the one that affects cats. SARS has a contagious nature, that's why it became a world epidemic. Many of the people who were infected with SARS had developed pneumonia. …show more content…

Middle East respiratory syndrome coronavirus (MERS-CoV) belongs to the family Coronaviridae, which from family of SARA-CoV and genus Betacoronavirus. It has a similar- stranded positive sense RNA genome structure. There was a lot of evidence that the MERS-CoV had been transmitted from person to person or from animals to
