US health officials defend Ebola response to Congress
Meanwhile, Ebola-infected nurse Nina Pham has been moved from Texas to the National Institutes of Health outside Washington, D.C.
In the face of skepticism in Congress, health officials tried to assure the nation Thursday that they can head off an Ebola outbreak in the US despite mistakes that let the deadly virus spread to two nurses and cleared one of them to fly.
The revelation that one of the hospital nurses was allowed on a commercial airline the day before she was diagnosed raised new alarms about the US response to the Ebola outbreak in West Africa. Some lawmakers pressed for a ban on travel to the US from the region — a course President Barack Obama is resisting.
Obama directed his administration to respond in a "much more aggressive way" to the threat and, for a second day in a row, canceled his out-of-town trips to stay in town and monitor the Ebola response. He was calling foreign leaders and U.S. lawmakers to discuss what more must be done, the White House said, and bringing his Cabinet members together on the matter.
But a ban on travel to the US from the Ebola-stricken countries is not under consideration, spokesman Josh Earnest reiterated Thursday.
Obama believes the US already is taking the necessary steps to protect the public by screening passengers as they depart West Africa and again when they enter the US, Earnest said.
In Sierra Leone, the government announced the virus had infected two people in the last part of the country that had been free of the disease, in the mountainous north, despite aggressive steps to keep it at bay.
The first nurse stricken in the US, Nina Pham, who contracted Ebola after treating a Liberian man at Texas Health Presbyterian Hospital in Dallas, was flown to the National Institutes of Health outside Washington on Thursday, while a second nurse has already been transferred to a biohazard infectious disease center at Emory University Hospital in Atlanta.
The two nurses, Pham and Amber Joy Vinson, had been involved in providing care to Thomas Duncan, who died of Ebola last week.
In a hearing on Capitol Hill, the chairman of a House committee cited "demonstrated failures" in the government's response. Rep. Tim Murphy of Pennsylvania said the "trust and credibility of the administration and government are waning as the American public loses confidence each day." Seated before him were leaders of the Centers for Disease Control and Prevention and the NIH.
Dr. Tom Frieden, director of the CDC, testified that despite the latest incidents, "we remain confident that our public health and health care systems can prevent an Ebola outbreak here."
In his prepared testimony, the Texas hospital's chief clinical officer, Dr. Daniel Varga, admitted the facility had made mistakes in Duncan's initial treatment, he apologized for that.
"We did not correctly diagnose his symptoms as those of Ebola," Varga said. "We are deeply sorry." Duncan was initially sent home from the emergency room with antibiotics for his high fever, despite saying he'd come from Liberia.
Varga testified to the committee by video conference.
In Europe, Spain's government is wrestling with treatment questions, too. The condition of a nursing assistant infected at a Madrid hospital appeared to be improving, but a person who came in contact with her before she was hospitalized developed a fever and was being tested Thursday.
That second person is not a health care worker, a Spanish Health Ministry spokesman said.
To this point, only hospital workers — the Madrid nursing assistant and the two nurses in Dallas — had been known to have contracted Ebola outside West Africa during the outbreak that began in March.
UN Secretary-General Ban Ki-moon said a trust fund he launched to fight Ebola, with a $1 billion goal, has a paltry $100,000 in the bank. He appealed to nations to do more about a "huge and urgent global problem that demands a huge and urgent global response." Some $20 million has been spent from the fund.
France said that on Saturday it will begin screening passengers who arrive at Paris' Charles de Gaulle airport on the once-daily flight from Guinea's capital.
In the US, Customs and health officials at airports in Chicago, Atlanta, suburban Washington and Newark, New Jersey, were to begin taking the temperatures of passengers from the three hardest-hit West African countries Thursday. The screenings, using no-touch thermometers, started Saturday at New York's Kennedy International Airport.
With hospitals and airports on heightened alert, Frieden said the CDC is receiving hundreds of requests for help in ruling out Ebola in travelers. So far 12 cases merited testing, he said.
Frieden said investigators are trying to figure out how the nurses caught the virus from that Liberian patient, Thomas Eric Duncan. In the meantime, he said, their cases show a need to strengthen the infection-control procedures that "allowed for exposure to the virus."
Duncan's death and the sick health care workers in the US and Spain "intensify our concern about the global health threat," said Dr. Anthony Fauci, director of the Institute of Allergy and Infectious Diseases at the National Institutes of Health.
He said two Ebola vaccine candidates were undergoing a first phase of human clinical testing this fall. But he cautioned that scientists were still in the early stages of seeking new treatments or a vaccine.
A nurse at the Dallas hospital, Texas Health Presbyterian, on Thursday described a "chaotic scene" when the hospital faced Duncan, its first Ebola patient.
Briana Aguirre, who has helped treat the first nurse who was infected, told NBC's "Today" show she felt exposed in the protective gear the hospital provided.
"In the second week of an Ebola crisis at my hospital, the only gear they were offering us at that time, and up until that time, is gear that is allowing our necks to be uncovered?" Aguirre said, adding that she piled on gloves and booties in triplicate and wore a plastic suit up to her neck.
The hospital said it used the protective gear recommended by the CDC and updated the equipment as CDC guidelines changed. Because nurses complained that their necks were exposed, the hospital ordered hoods for them, according to a statement from Texas Health Presbyterian.
Frieden said nurse Amber Joy Vinson never should have been allowed to fly on a commercial jetliner because she had been exposed to the virus while caring for the first Ebola patient.
Still, a CDC official cleared Vinson to board the Frontier Airlines flight from Cleveland to the Dallas area. Her reported temperature — 99.5 degrees — was below the threshold set by the agency, according to agency spokesman David Daigle.
Ebola patients are not considered contagious until they have symptoms.
Vinson was diagnosed with Ebola a day after the flight, news that sent airline stocks falling amid fears it could dissuade people from flying.
Frontier has taken the aircraft out of service. The plane was flown Wednesday without passengers from Cleveland to Denver, where the airline said it would undergo a fourth cleaning, including replacement of seat covers, carpeting and air filters.
