Coronaviruses (CoVs) belong to subfamily Orthocoronavirinae in the family of Coronaviridae. Historically, these viruses have been seen in a variety of mammalian and avian hosts and only cause mild disease except for three key outbreaks, which led to severe disease in immunocompetent hosts. In 2002 and 2003 coronavirus causing severe acute respiratory distress syndrome (SARS-CoV) emerged in China but luckily did not cause much mayhem. Then came the Middle East respiratory syndrome (MERS-CoV) in 2012, originating in Saudi Arabia and once again did not lead to any significant turmoil. Finally, the third strike came in the form of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which shook the entire world in December 2019 as it appeared in Wuhan, China. It forced the city of 11 million people in Central China to go under lock-down in January 2020 and affected not only China but also the majority of countries around the globe. United States of America (USA), United Kingdom (UK), Spain and Italy in particular saw the cruelty of this virus. World Health Organization (WHO) declared this “public health emergency of international concern”. Sure enough since then, it has led to public health calamity and economic predicament. The typical picture with SARS-CoV-2 is of pneumonia as demonstrated on chest imaging and the disease is called Coronavirus Disease 2019 (COVID-19). SARS-CoV-2 is an extremely contagious virus and has far exceeded the initial estimates of infection. There has been a lot of debate regarding the transmission of this virus and based on the evidence so far it seems like it is shed through multiple routes. One of the greatest challenges that we are facing at this time is to halt the spread and transmission of this deadly virus as the data does show that it can be spread by asymptomatic contacts [1].
