More than 81,000 people in China have been diagnosed with coronavirus since its emergence in the city of Wuhan, Hubei province, in December.
But there are more than 100,000 confirmed cases outside China, according to the latest figures from John Hopkins University.
However, the actual number of people with coronavirus internationally is thought to be a much higher number – as many of those with mild symptoms have not been tested and counted.

After China, Italy has the highest number of confirmed cases, with almost 28,000.
WHO director Tedros Adhanom Ghebreyesus, has said Europe is now at the centre of the global outbreak.
Iran and South Korea also have significant outbreaks, with more than 14,000 and 9,000 known cases respectively.
In response to the virus’s spread, countries around the world are ramping up measures to try to slow it down.
Governments have halted flights from virus-hit nations, locked down towns, urged people to stay at home, and suspended major sporting and social events.
US President Donald Trump has declared a national emergency, freeing up to $50bn (£40bn) in relief funds.
He has also announced travel restrictions on European countries. The measures – originally only applying to non-Americans travelling from countries which are members of the Schengen border-free travel area – have been extended to include the UK and Ireland from Tuesday. The restrictions are in addition to those applying to China and Iran.
A number of international conferences and sporting events have also been cancelled or postponed, including Six Nations rugby matches, Euro 2020 and the Copa America .
2. Italy has the most recorded cases outside China
Italy currently has the most confirmed cases outside China, having overtaken both South Korea and Iran.
It has almost 28,000 confirmed cases and a death toll of about 2,000.
Italian authorities have imposed stringent restrictions, closing nearly all shops, bars, hairdressers, restaurants and cafes until 25 March.
Schools, gyms, museums, nightclubs and other venues have also been shut, and people have been ordered to stay home and seek permission for essential travel.
A number of airlines, including British Airways, EasyJet and Ryanair, have cancelled Italy flights until the start of April.
3. Numbers across Europe are also rising
European countries have seen steep rises in infections and deaths, and the region has become the new epicentre of the crisis.
As well as Italy, Spain, France and Germany now have thousands of confirmed cases each.
Germany’s Chancellor Angela Merkel has warned that up to 70% of its population – some 58 million people – could contract coronavirus.
However, some German virologists dispute the high figure, suggesting a worst-case scenario of 40,000 cases.
In Spain, a state of emergency came into force on Saturday, with Prime Minister Pedro Sánchez warning that the number of confirmed cases in the country could top 10,000 next week.
In the UK confirmed cases stand at more than 1,900.
On Monday Prime Minister Boris Johnson announced a shift in strategy, urging everyone in the UK to avoid unnecessary social contact, work from home where possible, and stay away from pubs and restaurants.
4. China still has the most cases
The number of overall coronavirus cases in China has been rising since January, but has been levelling off over the last couple of weeks.
The country still has the highest number of confirmed cases of any country and accounts for about 81,000 of the 173,000 global cases.
Government and regional officials have imposed tight restrictions in a bid to reduce infections, including cancelling flights, closing schools and workplaces and ordering some cities to go into lockdown.
The origins of the coronavirus have been linked to illegally traded wildlife at the seafood market in Wuhan, capital of Hubei province, where the outbreak began. The exact source has not yet been identified.
