US cautiously optimistic after no new Ebola in 5 days

With no new Ebola cases in five days, US authorities were cautious but hopeful on Monday that the virus has been contained in the United States after a flawed response revealed shortcomings in the system.

Washington: With no new Ebola cases in five days, US authorities were cautious but hopeful on Monday that the virus has been contained in the United States after a flawed response revealed shortcomings in the system.

The fiancee of a Liberian man who died of Ebola earlier this month in Dallas, Texas, was among nearly 50 people who emerged from three weeks of quarantine without any signs of illness from exposure to the virus that has killed more than 4,500 in West Africa since the beginning of this year.

About 100 more people, most of them health care workers, are being tracked in Texas after coming in contact with the first patient diagnosed in the United States in late September.

Still, officials said it was reassuring that no new infections emerged in recent days.

"We are breathing a little bit easier, but we are still holding our breath," said Dallas Mayor Mike Rawlings.

Two US women were infected during the care of Liberian patient Thomas Eric Duncan. Both were nurses in the intensive care unit -- Nina Pham, whose infection was announced October 12, and her colleague Amber Vinson three days later.

Ebola is spread though close contact with vomit, blood, diarrhea or other bodily fluids. Most people get sick within eight to 10 days of exposure, and health care workers are particularly at risk.

Officials have sought to contain panic over the potential spread of Ebola, as fears mounted in the United States and a rash of suspected cases turned out to be nothing more than common illnesses.

"In the United States, two people have gotten infected with Ebola. Two. Both of them were taking care of a desperately ill patient in a risky situation," said Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, during a forum at Washington's Newseum.

"You have to distinguish the two nurses -- who were the only two people who were taking care of patients who got infected -- from the risk to the general public who aren't anywhere near an Ebola patient, much less a very sick Ebola patient."

Pham is in fair condition, and Fauci declined to speculate on whether she would make a full recovery.

"She still is a bit knocked out," Fauci said.

"When you get an infection as serious as Ebola it is very, very draining on you."

Vinson's family said in a statement yesterday they "remain intensely prayerful and optimistic about Amber's condition and of the treatment she is currently receiving" at Emory University Healthcare, in Atlanta Georgia, but gave no details on the state of her health.
