Coronavirus - a fast-moving infection originating in China - has spread to more than 80 countries and claimed more than 3,300 lives. Coronavirus - a fast-moving infection originating in China - has spread to more than 100 countries and claimed more than 3,800 lives.
While the vast majority of cases are in China, the virus, which causes pneumonia-like symptoms, is now spreading faster outside the country than within. While the vast majority of cases are in China, the virus, which causes pneumonia-like symptoms, is now spreading faster outside the country than within. South Korea, Italy and Iran have the highest number of confirmed cases.

1. Cases outside China continue to grow1. Cases outside China continue to grow
About 80,700 people in China have been infected with coronavirus since its emergence in the city of Wuhan, Hubei province, in December. About 80,900 people in China have been infected with coronavirus since its emergence in the city of Wuhan, Hubei province, in December.

2. The virus has pandemic potential 3. Italy, South Korea and Iran are among the worst-affected countries
The jump in the number of daily confirmed cases internationally has raised fears the outbreak could become a pandemic - when an infectious disease spreads easily from person to person in many parts of the world. Italy, South Korea and Iran have all seen significant outbreaks of cases, with South Korea and Italy the worst-affected countries after China.
The spread has reached a "decisive point" and has "pandemic potential", WHO head Dr Tedros Ghebreyesus says. In Italy, strict new quarantine measures in Lombardy and 14 provinces are affecting a quarter of the Italian population and centre on the rich northern part of the country.
Countries around the world are ramping up measures to battle the virus. Residents have been told not to enter or leave Lombardy - including in its main city Milan.
Some governments have halted flights from virus-hit nations, locked down towns, urged people to stay at home and suspended major sporting and social events. Authorities have also closed the country's schools, gyms, museums, nightclubs and other venues.
Some 13 countries have closed schools, affecting 290m children, while nine others have implemented localised closures, according to Unesco, the UN's educational, scientific and cultural organisation.
A number of international conferences and sporting events have been cancelled, including the Six Nations rugby matches between Ireland and Italy in Dublin that were to be held on 7 and 8 March.
The US state of California has declared a state of emergency.
The WHO, which declared the crisis a global health emergency on 30 January, has confirmed it will not formally "declare" a pandemic for the new coronavirus, though the term may still be used "colloquially".
International financial markets have continued to fall in recent days over fears that the outbreak could lead to a worldwide economic downturn.
3. South Korea, Italy and Iran are among the worst-affected countries
South Korea, Italy and Iran have all seen significant outbreaks of cases, with South Korea the worst-affected country after China.
South Korea's biggest virus clusters have been linked to a religious group near the south-eastern city of Daegu, which has a population of around 2.5m.
The mayor of capital Seoul has urged 10 million residents to work from home and to avoid crowded places.
Authorities have also postponed the start of the next school term until 23 March.
In Italy, as well as closing schools, authorities have introduced a month-long ban on attendance at sports events, and have advised people to avoid greetings like kissing on the cheek or shaking hands.
Most of the country's cases are concentrated in the wealthy northern regions of Lombardy and Veneto, where towns have been placed in quarantine.
Several countries, including Algeria, Denmark, Romania and Spain, have reported infections linked to Italy.Several countries, including Algeria, Denmark, Romania and Spain, have reported infections linked to Italy.
Iran has seen nearly 5,000 cases of the virus - with most in the capital, Tehran, and the regions of Gilan and Qom, where cases first emerged. In South Korea, the biggest virus clusters have been linked to a religious group near the south-eastern city of Daegu, which has a population of around 2.5m.
But, perhaps in a sign the country is getting on top of the outbreak, officials on Monday reported the lowest number of new cases in two weeks.
"The slowing trend should continue," President Moon Jae-in said in a statement, but warned: "We should not be complacent at all."
Many of the country's large events have been cancelled or postponed and the school holidays have been extended by three weeks, pushing back the return to classes.

4. China still has by far the most cases4. China still has by far the most cases
The number of overall coronavirus cases in China has been rising since January. The number of overall coronavirus cases in China has been rising since January, but has been levelling off in recent days.

Authorities also postponed the country's annual parliamentary gathering - the National People's Congress. 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.
Hubei province - the centre of the outbreak - remains the worst affected, seeing by far the biggest number of cases of the virus.
Its capital city of Wuhan, home to 11 million people, has been effectively shut down since 23 January, with transport links closed.
The origins of the coronavirus have been linked to illegally traded wildlife at Wuhan's seafood market, which sells live animals including pangolins, bats, rabbits and marmots. However, the exact source of the outbreak has not been identified.
The Chinese authorities have promised an investigation into alleged mismanagement by officials in Wuhan, where residents have been posting online videos of angry protests.
Hundreds of foreign nationals have been evacuated from Wuhan by several governments including the US, France and Britain.
5. Daily infections and deaths in China have been comparatively low recently5. Daily infections and deaths in China have been comparatively low recently

Medical researchers and scientists say it is too early to accurately predict how the virus will spread or calculate the death rate, partly due to mild cases remaining untested and unrecorded and a time lag of reporting infections.Medical researchers and scientists say it is too early to accurately predict how the virus will spread or calculate the death rate, partly due to mild cases remaining untested and unrecorded and a time lag of reporting infections.
