The move came as hard-hit Italy reported an additional 345 people had died from the virus, bringing its death toll to 2,503, and France imposed a draconian lockdown unseen during peacetime.
“The enemy is the virus and now we have to do our utmost to protect our people and to protect our economies,” European Commission President Ursula von der Leyen said after the grouping held its second videoconference in a week.
“We are ready to do everything that is required. We will not hesitate to take additional measures as the situation evolves.”
In the United States, meanwhile, the virus has been reported in West Virginia for the first time, meaning it has now spread to all 50 states. The Trump administration announced a plan to send money to Americans immediately to ease the economic pain resulting from the outbreak.
In other developments on Tuesday:
Italy’s total number of cases rose 12.6 percent to 31,506 – the slowest rate of increase since the first cases were reported on February 21.
Iran, with a death toll of 853 and 14,991 confirmed cases, has temporarily freed about 85,000 prisoners, including those held for political reasons.
The World Health Organization (WHO) has described the coronavirus pandemic as the “defining global health crisis of our time”, and urged countries to test all suspected cases of COVID-19.
Globally, the virus has infected 184,976 people and killed just over 7,500, according to the WHO. Almost 80,000 people have recovered from the infection, according to data collected by Johns Hopkins University.

03:15 GMT – Hong Kong to order all international arrivals into quarantine
Hong Kong will start issuing orders for 14 days compulsory quarantine to all people arriving in Hong Kong from overseas, regardless of whether they are Hong Kong residents.

03:10 GMT – Colombia turns to mass home isolation for the elderly
Colombia will enforce mass home isolation for the elderly, President Ivan Duque said on Tuesday.
The measure will come into effect on Friday.
The United Kingdom has also been considering whether to ask the elderly, who are more at risk from the virus, to stay at home.
03:05 GMT – Brazil seeking state of emergency to tackle virus
Brazil will seek authorisation for a state of emergency to allow it to scrap fiscal targets and free up funds to combat the coronavirus crisis, the government said on Tuesday, as President Jair Bolsonaro announced his second COVID-19 test was negative.
In a statement from the presidency, the government said it will ask Congress to authorise state of emergency measures until December 31.
Brazil reported the country’s first confirmed fatality from the outbreak on Tuesday.
“In view of the permanent monitoring of the COVID-19 pandemic, the need to increase public spending to protect the health and jobs of Brazilians and the prospect of falling revenues, the Federal Government will request the National Congress to recognize the state of emergency,” the statement from the president’s office said.
02:55 GMT – ‘Human biosecurity emergency’: Australia Prime Minister
Australian Prime Minister Scott Morrison has declared a “human biosecurity emergency”, giving the government the power to close off cities or regions, impose curfews and order people to quarantine, if seen as necessary to contain the spread of the virus.
Official travel advice, as we reported earlier, has been raised to an unprecedented “Level 4: Do not travel” to any country in the world. Any non-essential indoor gatherings of more than 100 people have also been banned.
“Life is changing in Australia, as it is changing all around the world,” Morrison said during a televised news conference. “Life is going to continue to change, as we deal with the global coronavirus. This is a once in a hundred year type event.”
Australia has recorded around 425 coronavirus infections and five deaths.

02:35 GMT – The body fights back: Australian researchers track immune system response
Reseachers at Australia’s Peter Doherty Institute for Infection and Immunity have mapped the immune system response of one of the first people to get COVID-19 in Australia, to find out more about the way in which the body fights the infection.
They took samples from an otherwise healthy woman in her 40s who’d been diagnosed with a mild-to-moderate case of the disease, to track her body’s response over time.
“Three days after the patient was admitted, we saw large populations of several immune cells, which are often a tell-tale sign of recovery during seasonal influenza infection, so we predicted that the patient would recover in three days, which is what happened,” said University of Melbourne Research Fellow Oanh Nguyen.
“We showed that even though COVID-19 is caused by a new virus, in an otherwise healthy person, a robust immune response across different cell types was associated with clinical recovery, similar to what we see in influenza,” added Katherine Kedzierska, a professor at the University of Melbourne.
“This is an incredible step forward in understanding what drives recovery of COVID-19. People can use our methods to understand the immune responses in larger COVID-19 cohorts, and also understand what’s lacking in those who have fatal outcomes.”
The paper has been published in NatureMedicine.
02:05 GMT – Contact tracing, self-isolation crucial: Diamond Princess report
Researchers from the National Institute of Infectious Diseases in Tokyo have released a preliminary investigation into the coronavirus outbreak on board the Diamond Princess.
The cruise ship, with 3,700 passengers and crew, was quarantined off the port of Yokohama for a month from February 3 after a passenger who got off in Hong Kong was confirmed with COVID-19.
The report focusses on the 20 cases confirmed among the crew, finding that transmission from passengers to staff had started before the ship was put into quarantine. Most of those who got the infection worked in food service for the crew, and also passed it on to those who shared their cabin.
The report’s authors said the findings indicated the need for a “swift” investigation as soon as a COVID-19 case is detected in a place where large groups of people gather, and the importance of self-isolation for close contacts.
01:50 GMT – South Korea reports 93 new cases
South Korea has also given an update on its numbers. The Korea Centers for Disease Control and Prevention says there were 93 new coronavirus cases on Wednesday, bringing total infections to 8,413.
While slightly more than the 84 recorded on Tuesday, it’s still the fourth day in a row that the country has reported fewer than 100 new infections.
01:43 GMT – China reports 13 new cases and 11 deaths
China’s National Health Commission has released its latest data on the outbreak there – 13 new confirmed cases were reported on Tuesday, down from 21 cases the day before.
That brings the total number of confirmed cases in mainland China to 80,894, the health authority said in a statement.
The death toll from the outbreak in mainland China had reached 3,237 as of the end of Tuesday, after 11 people died the previous day.
Those deaths were all in the central province of Hubei, with the provincial capital of Wuhan accounting for 10 of the fatalities.
The number of imported cases of the virus in mainland China reached 155 as of Tuesday, up 12 from a day earlier.
00:50 GMT – Australia advises citizens not to travel
Australia has urged its citizens not to travel given the risks from the coronavirus as it spreads around the world and heightened border controls that are forcing airlines to cancel flights.
It urged anyone already outside the country to return.
“There may be a higher risk of contracting COVID-19 overseas. You may come in contact with more people than usual, including during long-haul flights and in crowded airports,” the government said in upgrading the advice. “Healthcare systems in some countries may come under strain and may not be as well-equipped as Australia’s or have the capacity to support foreigners.”
