The World Health Organization says the official name for the disease caused by the new coronavirus is Covid-19.
It comes after the death toll from the virus passed 1,000.
Tens of thousands of people have been infected.
The word coronavirus refers to the group of viruses it belongs to, rather than the latest strain.
Researchers have been calling for an official name to avoid confusion and stigmatisation of any group or country.
The new name is taken from the words "corona", "virus" and "disease", with 2019 representing the year that it emerged (the outbreak was reported to the WHO on 31 December).
There are now more than 42,200 confirmed cases across China.
