Ans) Human coronaviruses usually cause mild upper respiratory diseases.

- Two coronaviruses transmitted from animals, SARS-CoV and MERS-CoV, have caused severe pneumonia and death in humans.

- COVID-19 pandemic has spread globally and consequently resulted in at least 282,719 deaths worldwide as of May 11, 2020.

- Due to the high sequence homology with a coronavirus isolated from bats, SARS-CoV-2 is considered a zoonotic origin coronavirus. Undoubtedly, SARS-CoV-2 has become the fifth human coronavirus, and it is possible that this virus will continuously circulate in the human population in the future.

- Because specific antiviral treatments and vaccines are still under development, testing, quarantine, and social distancing are encouraged to prevent virus spread. Nonetheless, since the virus keeps mutating and evolving during the pandemic, studies on viral pathogenicity, treatments and prophylactic vaccines should closely consider the genetic characteristics of the virus.
