Abstract
A new virus, Severe Acute Respiratory Syndrome Corona Virus-2 (SARS CoV-2) emerged in December 2019 and still continuing to pose a great threat all over the Globe claiming to a fatality 980,031 persons. Among the human corona viruses it is the third one causing acute respiratory distress syndrome. The others two are SARS CoV and MERS CoV. The objective of this study is to review the human corona viruses causing severe respiratory distresses which are detected thru analysis of some recently published documents on the deadly SARS CoV-2 as well as information on SARS-CoV and MERS CoV from different world class trust worthy reliable and dependable sources. Genetic analysis reveals that the new human corona virus (SARS CoV-2) has similarities with the severe acute respiratory syndrome like (SARS like) bat virus which thought to be the primary reservoir. SARSCoV and MERS-CoV also have same bat reservoir but the intermediate host are different for three human corona viruses. Though the clinical picture is more or less similar but efficiency of human to human transmission is not same for these viruses. So, strict control measures are critical to contain this very big pandemic been occurring since December 2019. Everyday new information has been coming causing strategy to change to control this pandemic. Zoonotic origin of corona viruses indicate researchers, public health specialists should keep the continuous surveillance for early detection of new virus alike SARS –CoV-2.International Journal of Human and Health Sciences Vol. 05 No. 02 April’21 Page: 139-147
