European foreign ministers are under pressure to scale up their response to the Ebola epidemic and will meet on Monday. Warnings of the disease becoming the "disaster of our generation" have been issued.
Ahead of the talks, Aid agency Oxfam, which works in the two worst-hit countries -- Liberia and Sierra Leone -- issued a stark call for more troops, funding and medical staff to be sent to the west African epicentre of the outbreak.
"There is a very strong political focus on this as the most immediate crisis facing us," a European diplomat said ahead of the meeting in Luxembourg.
Another EU diplomat said Britain -- which has a navy ship bound for Sierra Leone laden with medical staff and supplies -- hoped to "galvanise EU action on Ebola".
"There is a real sense that this is a tipping point and we must get to grips with it now," said the diplomat. "If we can deal with it in the country, we don't have to deal with it at home."
The worst-ever outbreak of the deadly virus has so far killed more than 4,500 people, mainly in Guinea, Liberia and Sierra Leone, but isolated cases have now begun to appear in Europe and the United States.
Oxfam chief executive Mark Goldring said the world was "in the eye of a storm" as the charity warned Ebola "could become the definitive humanitarian disaster of our generation".
"Countries that have failed to commit troops, doctors and enough funding are in danger of costing lives," he said.
Part of the solution, the EU diplomats said, was giving international medics -- on the frontline in the Ebola battle -- the confidence they would receive EU-level care if they get sick, with access to medical evacuation flights.
- Spooked public -
The World Bank has warned the battle is being lost against the disease, which spreads via contact with bodily fluids and for which there is no licensed treatment or vaccine.
A global UN appeal for nearly $1 billion (785 billion euros) to fight the spread of the disease has so far fallen short, although a spokesman told AFP more money was coming in daily.
Out of $988 million requested a month ago, the UN said Saturday $385.9 million had already been given by a slew of governments and agencies, with a further $225.8 million promised.
As the death toll in Sierra Leone rose to 1,200, the country said it was putting Defence Minister Alfred Paolo Conteh in charge of a new national Ebola response centre.
With panic spreading in Western countries fearing a spread of the tropical disease, US President Barack Obama named an "Ebola czar" to coordinate crisis response.
Obama also cautioned against "hysteria" after a string of Ebola false alarms among a US public spooked by the news that two American nurses had contracted Ebola after treating a Liberian patient who died on October 8.
"This is a serious disease, but we can't give in to hysteria or fear," Obama said. "We have to be guided by the science."
At the Pentagon on Friday, an entrance was closed after a woman vomited in a parking lot. US authorities later found no evidence that she had contracted Ebola.
Meanwhile, US media reported on overzealous action taken by some worried communities, including a group of Mississippi parents who pulled their children from school because the principal had traveled to Zambia -- a southern African country far from the Ebola crisis in west Africa.
- Airport checks -
The US president played down the idea of a travel ban from west Africa, as World Bank chief Jim Yong Kim criticised countries for being overly focused on securing their own borders, rather than helping tackle the epidemic at source.
The United States, Britain and Canada were joined this weekend by France in carrying out airport screenings for passengers from Ebola-hit zones. The EU is to further review the situation this week.
One 40-year-old passenger from Guinea, where the epidemic began in December, was taken to a Paris hospital with a suspected fever on Saturday but officials later said she was not suffering from vomiting or diarrhoea.
Meanwhile, a woman suffering from abdominal pain and fever was being treated in isolation at a military hospital near Paris, while tests were carried out for Ebola.
As of October 14, 4,555 people had died from Ebola out of a total of 9,216 cases registered in seven countries, the World Health Organization said.
