The release of a Dallas nurses leaves only one Ebola patient still in the United States. Yet there's still a lot going on, in West Africa and beyond, related to the fight against the deadly virus.
Here's some of the latest:
WEST AFRICA DEVELOPMENTS
U.S. diplomat arrives in Liberia
Samantha Power, U.S. ambassador to the United Nations, arrived Tuesday in Liberian capital of Monrovia, telling reporters there that her visit intends "to show solidarity with the people of the region so that you know that you are not alone as you face this terrible epidemic."
Power talked about U.S. contributions so far -- including federal health experts and about 1,000 troops -- and its commitment to ensuring that Liberia emerged from this epidemic "stronger and even more resilient" than ever.
Details emerge about patient zero
Researchers from The New England Journal of Medicine believe 2-year-old Emile Ouamouno was the first person to contract Ebola in the current outbreak.
Emile, who lived in a southern Guinea village, died in December. It's not exactly clear how Emile got infected, but the virus also killed his sister, mother and grandmother before spreading like wildfire to neighboring countries Liberia and Sierra Leone.
Obama: U.S. making an impact in West Africa
President Barack Obama said Tuesday that Americans deployed to West Africa since August have had a positive impact in the fight against the Ebola virus. "They are starting to see some progress in Liberia," he said. "That's thanks to the incredible work and dedication of folks from the United States who are leading the way in helping Liberia, Guinea and Sierra Leone," Obama added, referring to the three countries hit hardest by the disease.
Urges not to react 'based on our fears'
Obama said Tuesday that while there must be "sensible" monitoring upon their return home, health care workers who go to West Africa to fight Ebola should be supported and applaud for their worthwhile efforts.
He said that reactions shouldn't be "based on our fears (but rather) on facts," adding that "we don't want to discourage our health workers from going to the front lines and dealing with this in an effective way."
Obama to meet with health care workers
The President will meet Wednesday with health care workers who have gone to West Africa to fight Ebola or will soon be heading there, he said.
Infected nurse now free of Ebola
Amber Vinson, one of two Texas Health Presbyterian Hospital Dallas nurses infected after treating Ebola patient Thomas Eric Duncan, was discharged Tuesday from Atlanta's Emory University Hospital. Vinson expressed gratitude to God and those who treated her, while appealing to the American public not to forget the thousands of families dealing with the Ebola outbreak in West Africa.
Hospital has learned 'a great deal'
Dr. Bruce Ribner, the medical director of Emory's serious communicable disease unit, said Tuesday that his hospital has learned "a great deal" after treating for Ebola patients, including Vinson. Those lessons -- about things such as fluid and electrolyte management and that physicians can successfully treat Ebola patients who need dialysis -- are being shared with colleagues in West Africa and the United States, Ribner said.
One Ebola patient still in United States
Vinson's release means that there's only patient -- Dr. Craig Spencer at New York City's Bellevue Hospital -- in the United States with Ebola. The Doctors Without Borders worker was admitted to the hospital on Thursday, six days after arriving back in New York.
New York boy doesn't have Ebola
A 5-year-old boy who recently visited West Africa and had a fever tested negative for Ebola in New York, health officials said. The boy -- who had a respiratory infection, which caused his temperature to spike -- is being taken out of isolation, CNN has learned, but he'll remain at Bellevue Hospital.
Military members quarantined
At least 41 U.S. Army personnel will be monitored for symptoms in Italy after working in West Africa. On Tuesday, a U.S. Army official said 30 members will arrive Wednesday for monitoring. That's on top of the 11 personnel, including Army Maj. Gen. Darryl A. Williams, who are now in "controlled monitoring" in Italy after setting up the initial U.S. military assistance in West Africa. There was no indication that team members had any symptoms of Ebola, but they will be monitored for 21 days.
New York students attacked
A group of students in the Bronx attacked two peers while yelling "Ebola" at the brothers who had recently returned from Senegal, the boys' father told CNN affiliate News 12. The New York Department of Education confirms the incident occurred, saying the boys were pushed and shoved.
Quarantined nurse released
A day after she said her human rights were being violated, nurse Kaci Hickox has been released from a New Jersey hospital. Hickox was isolated Friday after spending a month in Sierra Leone helping treat Ebola patients -- even though Hickox has repeatedly tested negative for Ebola.
CDC updates quarantine guidelines
The Centers for Disease Control and Prevention released updated guidance for those concerned about exposure to Ebola. "The new guidelines increase the level of protection by outlining different levels of exposure and outlining different public health actions that can be taken for each of those levels of exposure," CDC Director Dr. Tom Frieden told reporters.
France details help for Guinea
French President Francois Hollande announced Tuesday what he called a "comprehensive plan" to help combat Ebola centered on France's former colony of Guinea. France's contributions will include up to 20 million euros ($25.5 million) in funding, opening up a 200-bed, Red Cross-operated medical facility in Guinea around mid-November and establish two training centers in France and Guinea for health care workers.
Swiss authorities approve Ebola vaccine
The World Health Organization said Swissmedic, the Swiss regulatory agency for therapeutic products, has approved an Ebola vaccine trial at Lausanne University Hospital. That means the vaccine can be used on about 120 people in Lausanne. Other trials are also taking place in the United States, the United Kingdom and Mali.
Australia tightens travel from West African countries
Australia has stopped processing visa applications from Guinea, Sierra Leone and Liberia, Immigration and Border Protection Minister Scott Morrison said.
He added that those who hold permanent Australian visas based in those countries would be subject to a mandatory, three-week quarantine process before their departure from those countries.
