Answer:
The coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged in Wuhan, China and spread around the world. Genomic analysis revealed that SARS-CoV-2 is phylogenetically related to severe acute respiratory syndrome-like (SARS-like) bat viruses, therefore bats could be the possible primary reservoir. The intermediate source of origin and transfer to humans is not known, however, the rapid human to human transfer has been confirmed widely. There is no clinically approved antiviral drug or vaccine available to be used against COVID-19. However, few broad-spectrum antiviral drugs have been evaluated against COVID-19 in clinical trials, resulted in clinical recovery. In the current review, we summarize and comparatively analyze the emergence and pathogenicity of COVID-19 infection and previous human coronaviruses severe acute respiratory syndrome coronavirus (SARS-CoV) and middle east respiratory syndrome coronavirus (MERS-CoV). We also discuss the approaches for developing effective vaccines and therapeutic combinations to cope with this viral outbreak
Explanation:
The COVID-19 outbreakhas reached every continent on Earth besides Antarctica. The respiratory disease, caused by a never-before-seen coronavirus, has upended life across the globe, shutting down entire cities and countries in a matter of months. The economy has come to a screeching halt. The epicenter -- Wuhan, China -- experienced the worst of the initial outbreak but appears to be getting things under control whereas huge, secondary outbreaks have appeared in Europe and the US.
The WHO was first alerted to the disease on New Year's Eve, and in the following weeks researchers linked it to a family of viruses known as coronaviruses, the same family responsible for the diseases SARS and MERS, as well as some cases of the common cold.
