The new coronavirus. At the end of 2019, a new type of coronavirus started spreading in China. This type of coronavirus is often called 2019-nCoV, novel coronavirus, or COVID-19.

Unfortunately, when viruses are transmitted from animals to people it can take scientists a lot of time before they can develop a vaccine or medicines to cure it.

How does the virus spread? The virus appears to spread mainly from person to person. The transmission occurs when someone comes into contact with an infected person. For example, a cough, a sneeze or a handshake could cause transmission. The spread may also be caused by coming into contact with something an infected person has touched and then touching your mouth, nose or eyes.
