MONDAY, Oct. 20, 2014 (HealthDay News) -- An unidentified patient being treated at Emory University Hospital in Atlanta is now "free of Ebola virus disease" and was discharged Sunday from the facility, the medical center said in a statement released Monday afternoon.
The man, who has requested anonymity since being admitted to care at Emory's Serious Communicable Disease Unit on Sept. 9, now poses no threat to public health and has left the hospital for an "undisclosed location," the hospital added.
Emory had previously successfully treated two medical missionaries who became infected in West Africa, the site of the worst Ebola outbreak in history.
Also Monday, the American video journalist infected with Ebola while working in Liberia is improving and could be released from the hospital by week's end, doctors at Nebraska Medical Center in Omaha said. Ashoka Mukpo, of Providence, R.I., has been undergoing treatment at the hospital since Oct. 6.
The dual announcements followed more good news on the Ebola front in the United States: Dozens of people who had contact with the Dallas patient who died earlier this month are no longer in danger of catching the disease, health officials said Monday.
Those people include the fiancee and other family members of Thomas Eric Duncan, the Liberian native who contracted the disease in his home country before arriving in Dallas last month.
Also cleared were the paramedics who drove Duncan to Texas Health Presbyterian Hospital on Sept. 28 and health care workers who drew or processed his blood. And a mandatory quarantine was lifted for a homeless man who later rode in the same ambulance as Duncan before it was disinfected, The New York Times reported.
All told, the 21-day monitoring period ended Sunday and Monday for roughly 50 people, the newspaper reported.
An estimated 120 people remain under watch because they could have had contact with one of the three people in Dallas who came down with the disease. Besides Duncan, the other two include two nurses who treated him at Texas Health Presbyterian Hospital.
Federal health officials have said that symptoms of Ebola show up within 21 days of exposure to the virus.
In other developments:
Meanwhile, U.S. health officials on Monday tightened guidelines for health care workers who are treating Ebola patients.
The new recommendations call for full-body suits and hoods with no skin exposure and use of a respirator at all times. There will also be stricter rules for removing equipment and disinfecting hands, and the designation of a "site manager" to supervise the putting on and taking off of equipment used while treating a patient.
The revised guidelines are apparently in response to the two nurses in Dallas who became infected with Ebola while treating Duncan, the first diagnosed case of the disease in the United States.
Health officials aren't sure how the nurses became infected with the often deadly disease, which has decimated three West African nations since last spring.
But Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, said Sunday that the nurses caring for Duncan had some of their skin exposed, the AP reported.
"Very clearly, when you go into a hospital, have to intubate somebody, have all of the body fluids, you've got to be completely covered. So, that's going to be one of the things," the news service quoted Fauci as saying.
Also Sunday, U.S. Defense Secretary Chuck Hagel announced the creation of a 30-member team of military personnel to help civilian medical professionals in the United States if its assistance is needed to treat Ebola. The team will include doctors, nurses and infectious disease experts, the AP reported.
To date, there have been three cases of Ebola diagnosed in the United States: the two nurses and Duncan.
Early Sunday morning, a cruise ship carrying a lab worker who was being monitored for Ebola because she'd handled a lab specimen from Duncan returned to its port in Galveston, Texas, cruise line officials said.
The unidentified woman is a laboratory manager at Texas Health Presbyterian. She had been voluntarily quarantined aboard the Carnival ship with her husband. She was showing no signs of symptoms of the disease and posed no risk because she has been symptomless for 19 days, federal officials said, according to the AP.
Carnival Cruise Lines said it had been told by health officials Sunday morning that the lab worker tested negative for Ebola, the news service said.
And Spanish health authorities reported Sunday that a nurse's aide who had become infected with Ebola while caring for an elderly priest was free of the virus.
On Saturday, President Barack Obama called on Americans not to give in to panic over Ebola. And he repeated his opposition to a travel ban for flights from the three affected countries in West Africa -- Guinea, Liberia and Sierra Leone.
In his weekly radio and Internet address, Obama said Ebola "is a serious disease, but we can't give in to hysteria or fear -- because that only makes it harder to get people the accurate information they need. We have to be guided by the science."
Some lawmakers have called for a travel ban, but Obama believes such a move would be counterproductive. "Trying to seal off an entire region of the world -- if that were even possible -- could actually make the situation worse," he said.
The Ebola outbreak in West Africa has killed nearly 4,500 people out of an estimated 9,000 reported cases, according to the World Health Organization.
