What is the new coronavirus from China?
The coronavirus is a sort of virus, a tiny infectious germ.
Under a microscope, it looks as if these viruses are surrounded by a small crown. Hence their name: coronavirus!
They mainly infect the nose and the lungs. Some people may just catch a simple cold, but others can be seriously ill.
So how do you catch a coronavirus?
They are spread through the air. When an infected person coughs or sneezes, they can contaminate those around them.
