Story highlights Health official: With no fever and no contact, there is no risk

Son on hospitalized deputy: We don't think he has Ebola

Fire chief: Health officials are treating it "as a low-risk event"

The first person diagnosed with Ebola in the United States dies

There's "no risk of Ebola" for a Dallas deputy who was hospitalized with possible symptoms of the virus, a Texas health official said Wednesday.

The deputy, named by local media as Sgt. Michael Monnig, didn't have any direct contact with Thomas Eric Duncan, the man who died of Ebola in Dallas on Wednesday.

"We know he didn't have direct contact with the patient (Duncan) and he doesn't have a fever, and in a situation like that there is no risk of Ebola," said Chris Van Deusen, spokesman for the Texas Department of State Health Services.

The patient -- who was transported from Frisco, Texas -- had reported being in the Dallas apartment where Duncan had been staying and having "some contact" with Duncan's family members, Frisco Fire Chief Mark Piland told reporters.

Monnig was a first responder and had spent about 30 minutes in the apartment, his son told CNN affiliate KTVT. He woke up Wednesday, feeling sore and fatigued and with a stomachache.

"With the situation, what's happened, he just decided it would be better to be safe than sorry," Logan Monnig told KTVT.

The family does not expect that Monnig has Ebola, but still, his son said, "We're kind of scared and just want to make sure he's OK."

The patient was admitted to the emergency room at Texas Health Presbyterian Dallas "after reporting possible exposure to the Ebola virus," the hospital said.

"Right now, there are more questions than answers about this case," the hospital said. "Our professional staff of nurses and doctors is prepared to examine the patient, discuss any findings with appropriate agencies and officials."

Asked about the case by reporters, Centers for Disease Control and Prevention Director Dr. Tom Frieden said the patient "does not have either definite contact with Ebola or definite symptoms of Ebola."

A spokeswoman for CareNow, which made the call to emergency dispatchers, said the medical center "was being very cautious" after the patient checked yes in response to a screening question.

In addition to Monnig, two other deputies from the department are feeling sick, Scott Guiselman, president of the Dallas Sheriff Fraternal Order of Police, told CNN's Erin Burnett.

But state and local officials said they weren't aware of any other cases of Ebola-like symptoms.

The new patient's case was the latest development as fears and concerns over Ebola spread worldwide. With multiple developments on numerous fronts, here's what you need to know to quickly get caught up on the latest:

WEST AFRICAN CASES

Grim tolls:

The United Nations said that one of its medical officials in Liberia had contracted Ebola and was being treated there. The international worker, who's not been named, is the second member of the U.N. mission in Liberia to be infected with the virus. The first died on September 25.

U.S. CASES

Thomas Eric Duncan, the first person diagnosed with Ebola in the United States, died Wednesday, according to Texas Health Presbyterian Hospital, where he was being treated.

Duncan had been on a ventilator and on dialysis for failing kidneys, health officials said.

The country launched a five-year study to unravel the mystery of the long-term health effects that plague survivors of the viral disease. Since the epidemic started more than a year ago in a remote village in Guinea, more than 11,000 people have died, the vast majority in three West African nations, according to the latest numbers from the World Health Organization . And that number is believed to be low, since there was widespread under-reporting of cases, according to WHO.

JUST WATCHED Tough to recruit workers to fight Ebola Replay More Videos ... MUST WATCH Tough to recruit workers to fight Ebola 04:13

Duncan received an experimental medicine nearly a week after being admitted into a hospital -- a far longer wait than experienced by four other Ebola patients treated in the United States. The others are Americans; Duncan is Liberian.

NBC cameraman recovering:

NBC cameraman Ashoka Mukpo is "reasonably stable," but a doctor cautioned it's too early to say he's out of the woods. The American citizen got infected in Liberia, and he was airlifted to Omaha, Nebraska, for treatment Sunday. He's receiving an experimental drug called brincidofovir, or CMX001.

Dr. Kent Brantly , an Ebola survivor, has donated his blood to Mukpo, which may contain life-saving antibodies, according to the Samaritan's Purse aid group. Brantly previously did the same for another Ebola patient, Dr. Rick Sacra , who was treated at the same Omaha center as Mukpo and survived.

New travel screening:

The Centers for Disease Control and Prevention announced beefed-up measures at five of America's biggest, busiest airports aimed at preventing the further spread of Ebola.

About 150 people a day arriving in the United States after having recently traveled from Ebola-ravaged West African nations of Guinea, Liberia and Sierra Leone will get special treatment, including having their temperature taken and answering questions about whether they've been exposed to anyone with Ebola, Frieden said.

EUROPEAN CASES

Spain ramps up response:

After a nurse's assistant in Spain became the first person to contract Ebola outside Africa in the current outbreak, six people related to the case were in a Madrid hospital as of late Wednesday, including two doctors and a male nurse admitted earlier in the day, Carlos III hospital said in a press release.

The nurse's assistant is the only one confirmed to have Ebola. Besides the three new cases, the others include the woman's husband, judged to be at high risk of infection, and a nurse from the same hospital. Two others were released from Carlos III hospital earlier Wednesday -- a Spanish man who'd recently come from Nigeria and a female nurse.

Norwegian tests positive:

An unnamed Norwegian national , a staffer with Doctors Without Borders, has contracted the virus while working in Sierra Leone. The staffer was put in isolation Sunday and will be moved to Europe for treatment.

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.

RESPONSE

Closed wallets:

The Ebola outbreak may dominate the headlines, but few Americans are opening up their wallets . Four major U.S. aid organizations surveyed by CNNMoney have received a combined total of $19.5 million so far. Much of that came from nonprofit foundations, not individual donors. Last month, the United Nations said it would need nearly $1 billion to fight the virus.

France giving $88 million:

France is contributing about $88 million to fight the Ebola outbreak, the French Foreign Ministry said.

Outbreak's possible cost? $32 billion:

The outbreak of Ebola in western Africa could cost the continent's economies $32 billion over the next two years if it spreads to its larger neighbors, the World Bank estimated in a report Wednesday.
