This week's revelation that two Dallas nurses contracted Ebola from the first patient diagnosed with the virus in the U.S. realized the fears of public health officials and sparked new questions over the government's ability to respond to the disease.
With numerous stories stemming from the new cases in the U.S. and additional news from overseas, here's a glance at new Ebola coverage from Friday:
Airline: 2nd nurse may have had more advanced case of Ebola
The president of Frontier Airlines says a nurse who was on flights between Dallas and Cleveland and who later tested positive for Ebola may have been at a more advanced stage of the illness than previously thought.
Amber Joy Vinson, 29, was diagnosed with Ebola on Wednesday. She had helped treat Thomas Eric Duncan, the first Ebola patient in the U.S., at Texas Health Presbyterian Hospital before the Liberian man died last week. She was transferred to Atlanta's Emory University Hospital Wednesday for treatment.
Frontier president Barry Biffle emailed employees Friday about the findings by the Centers for Disease Control and Prevention. He said the CDC has assured the Denver-based airline that crewmembers on the flights Vinson took before she was diagnosed are at a very low risk of exposure.
The airline put the pilots and flight attendants on leave for 21 days, which health experts consider the outer limit of how long it would take someone exposed to Ebola to become sick.
Biffle says passengers on Amber Joy Vinson's flight from Dallas to Cleveland on Oct. 10 and her return flight to Dallas on Monday have been notified.
Update: White House, Texas name three officials to handle Ebola response in Dallas
In an effort to coordinate the response in Dallas between federal and state authorities, three new designees have been named, the White House said Friday. Each person will serve in an on the ground capacity fulfilling needs for those calling on the federal government.
Gov. Rick Perry has chosen W. Nim Kidd, Chief of the Texas Division of Emergency Management and Assistant Director, Texas Department of Public Safety.
Also, FEMA coordinator, Kevin Hannes will serve with Kidd to ensure all federal assistance is being distributed properly.
Finally, Adrian Saenz, White House Special Assistant to the President will ensure that state and local authorities will be able to obtain any federal resources
Obama names Ebola czar
President Obama named former White House official Ron Klain to serve as a so-called "Ebola czar" to oversee the government's handling of the virus, following calls from a number of lawmakers for a single point person in the administration to oversee the government's response to the virus.
Klain, who previously served as chief of staff for Vice President Joe Biden and for Vice President Al Gore, will report directly to Lisa Monaco, the president's homeland security adviser, and national security adviser Susan Rice, the White House said.
Officially, Klain will be referred to as the "Ebola Response Coordinator," according to White House Press Secretary Josh Earnest. Some Republicans criticize the president's choice due to Klain's lack of medical experience.
Woman in Pentagon scare does not have Ebola
A woman who said she had recently been to Africa and who vomited in a Pentagon parking lot Friday morning does not have the virus, health officials in Virginia say.
The woman told first responders she visited Sierra Leone, CBS affiliate WUSA in Washington, D.C., reports, and was taken to Inova Fairfax Hospital to be evaluated.
"Based on the public health investigation, which included the travel history of a woman who became ill this morning in a Pentagon parking lot, and on questioning of her by medical staff, medical authorities are confident that she does not have Ebola," according to a joint statement released Friday evening by the public health departments in Arlington and Fairfax, Virginia.
CBS News national security correspondent David Martin reports that the woman was on a bus taking people from the Pentagon to a change-of-command ceremony for the commandant of the Marine Corps in downtown Washington when she said she felt sick and asked to get off the bus. The woman worked for a contractor that does business with the Pentagon.
Dr. Joxel Garcia, director of the Department of Health for the District of Columbia, said at a news conference earlier in the day that the 22 people on the bus were held until authorities were able to get their names and contact information, and were monitored while waiting for word on the woman's status. Garcia added that there was only a low risk that the woman could transmit Ebola to other people on the bus.
Nurse "very fatigued" but "in good spirits"
The director of infectious diseases at the National Institutes of Health said Friday that doctors "fully intend" to have infected nurse Nina Pham "walk out of this hospital."
Overnight, Texas Health Presbyterian released an emotional video of Pham before she was transferred to the NIH in Maryland to continue her treatment for the disease.
Dallas patient to be tested
Another Dallas patient was to be tested for Ebola, a hospital spokesman said Friday.
Baylor University Medical Center spokesman Craig Civale said the patient screened positive for the virus but stressed that that could mean many things. The screening includes whether a person has been to West Africa and has a fever.
The patient was transferred for further tests to Texas Health Presbyterian, the hospital where Thomas Eric Duncan, the first patient diagnosed with Ebola in the U.S., received treatment and died last week.

Obama fans travel ban fever

Poll: Public confidence in CDC nosedives
Americans' faith in the agency charged with protecting the homeland from the outbreak has dropped sharply since the crisis emerged.
A CBS News Poll has found that positive assessment of the Centers for Disease Control and Prevention has declined dramatically, with only 37 percent of respondents saying the CDC is doing an excellent or good job -- down from 60 percent in a May 2013 Gallup poll.
Cruise ship passenger monitored
Ebola concerns now stretch from the United States to Central America. A Carnival cruise was on hold Friday morning off the coast of Belize. A passenger may have handled bodily fluids from Duncan. She works at the hospital in Dallas, where Duncan died last week. The worker is in isolation but shows no symptoms.
What should Ebola health care workers wear?
Federal and state health officials are trying to determine how to more effectively keep health care workers safe. The director of the Center for Disaster Medicine at New York Medical College told CBS News that many hospitals are wrestling with what type of gear to provide to their medical staff.

The CDC expanded its search for people who may have had contact with infected nurse Amber Vinson when she traveled from Dallas to Ohio last weekend on a commercial flight while becoming ill with the virus.
Outbreak over in Senegal
The World Health Organization declared the outbreak in Senegal over Friday.
The country's lone introduced case was confirmed Aug. 29. A young man had traveled to Dakar, Senegal, by road from Guinea, where he had direct contact with an Ebola patient.

The patient tested negative for Ebola Sept. 5 and returned to Guinea Sept. 18.
Political blame game over Ebola funding
With voters going to the polls in less than three weeks, Democrats and Republicans are trading charges over which party has been the better champion for the CDC and the NIH.
