The coronavirus owes its name to its appearance. It is like a crown. It's a type of virus present in humans and animals.
It is transmitted by close contact with respiratory secretions that are generated with cough or sneezing from a sick person. Its contagiousness depends on the amount of the virus in the respiratory tract. These secretions would infect another person if they come into contact with their nose, their eyes or his mouth.
