Answer:
COVID-19 is caused by the virus SARS-CoV-2.
Where Did the Coronavirus Come From? Experts say SARS-CoV-2 originated in bats. That's also how the coronaviruses behind Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) got started.
But it is a virus that has never been seen in humans, so absolutely no one is immune to it. That added to the fact that it spreads as easily from person to person as influenza, and infects the upper respiratory system, is what makes it so dangerous
The virus that cause COVID-19 spreads primarily through droplets generated when an infected person coughs, sneezes or speaks. You can also become infected by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands.
While the Centers for Disease Control and Prevention (CDC) and other public-health authorities put the incubation period for the virus at 2–14 days, most people who become ill develop symptoms between five and six days after exposure
