Ebola: More fears, more measures as first patient diagnosed in the U.S. dies

With developments pouring in from all corners of the world, here's what you need to know Thursday to quickly get caught up on the latest:

WEST AFRICAN CASES

No relief in sight:

To date, the world's largest outbreak of Ebola has killed more than 3,400 people in Guinea, Liberia and Sierra Leone -- the nations hardest hit. And it's affecting medical workers alike. A United Nations official is undergoing treatment in Liberia after contracting Ebola. The unnamed worker is the second U.N. member infected with the virus in Liberia. The first one died last month.

A $32 billion hit:

The outbreak could cost the African economy $32 billion over the next two years if it spreads to its larger neighbors, the World Bank estimates.

U.S. CASES

Thomas Duncan dies:

Thomas Eric Duncan, the first person diagnosed with Ebola in the United States, died Wednesday, 10 days after he was admitted to a Texas hospital. His family wonders if the outcome would have been different if doctors had admitted Duncan to hospital on September 25, the first time he showed up with a fever and stomach pain?

Dallas deputy hospitalized:

A Dallas deputy has been hospitalized with possible symptoms of the virus, but there's "no risk" of Ebola, a Texas health official said Wednesday. The deputy, Sgt. Michael Monnig, didn't have any direct contact with Duncan.

New travel screening:

Five of America's biggest, busiest airports are beefing up measures. Now, people arriving from the three nations hardest hit by Ebola will get special screening, including having their temperature taken. The airports are: New York's JFK, Washington-Dulles, Newark, Chicago-O'Hare and Atlanta international airports.

EUROPEAN CASES

Spain ramps up response:

After a nurse's assistant in Spain became the first person to contract Ebola outside Africa, five people related to the case were being monitored in a Madrid hospital, including her husband, an ER doctor and the neighborhood doctor who saw her before the case was confirmed.

'Save Excalibur' fails:

Despite a public push to save its life, Excalibur -- the Spanish nurse assistant's dog -- was euthanized because of concern it may have become infected with Ebola. Critics said the dog should have been quarantined, just like the assistant's husband has been.

Infections 'unavoidable':

Sporadic Ebola infections will be unavoidable in some European countries because of direct travel from their hubs to hotspot areas in West Africa, the World Health Organization said Wednesday. But the risk of spread, it said, is avoidable and extremely low.

Australia scare:

A 57-year-old woman who returned to Australia after treating Ebola patients in Sierra Leone has been isolated at a hospital and is undergoing tests, including one for the deadly virus, authorities said. She had isolated herself at home and checked her temperature twice daily since her return, as recommended by national guidelines.
