In late September, Thomas Duncan became the first person to be diagnosed with Ebola in the U.S. Two hospital workers who treated him also became infected, setting off a nationwide effort to contain the disease, and fears of a larger outbreak.

U.S. Announces Protected Status for People from Ebola-Affected Countries

The U.S. is now extending protected status to people currently in the country from Sierra Leone, Guinea, and Liberia, Reuters reported earlier today.

The Department of Homeland Security estimated that around 8,000 people from the three West African countries most affected by Ebola would now be able to apply for work permits, as well as immunity from deportation. These protections, which apply only to people already in the U.S. as of today, will last for 18 months, at which point officials will re-assess based on the state of the epidemic.

As a means of controlling virus transmission, those who receive protected status are forbidden from traveling to West Africa and returning to the United States. People must submit to a background check before applying, an official from Homeland Security told Reuters, and those with criminal backgrounds will not be eligible.

The Ebola death toll currently stands at 5,420, according to the World Health Organization. The WHO said yesterday that transmission of the virus is still particularly “intense and widespread” in Sierra Leone, where only 13 percent of patients have been successfully isolated.

Doctor Brought to U.S. Dies of Ebola

Dr. Michael Salia, a U.S. resident who contracted Ebola while working as a surgeon in his native Sierra Leone, died this morning at the Nebraska Medical Center in Omaha. The 44-year-old Salia was already acutely ill upon his arrival in the U.S. on Saturday with kidney and respiratory problems. He has become the second person to die of Ebola in the United States. The first, Thomas Eric Duncan, passed away in Dallas last month after contracting the illness in Liberia.

According to NBC News, Salia had a wife and two children living in the New Carrollton, Maryland. "Even though he knows the sickness is already out, he decided to still go and help his people because he wanted to show that he loves his people," his son, Maada, said.

Salia initially underwent an Ebola test that came back negative in Sierra  Leone earlier in the month, but when his symptoms persisted, a second test showed the disease, the Washington Post reported. Doctors say early detection is critical to treating Ebola.

U.S. Announces Enhanced Airport Screening for Mali Travelers

Travelers entering the U.S. from Mali will now be subject to enhanced Ebola screenings at airports as concerns grow about the latest outbreak in the West African nation.

The Department of Homeland Security cited a "number of confirmed cases" in Mali in recent days as well as the large number of individuals who have been exposed to Ebola as reasons for the change. The U.S. had previously implemented enhanced airport screenings for passengers from Liberia, Guinea, and Sierra Leone. Dozens of people in Mali have now been quarantined after the death of a nurse who treated a Guinean man who died of Ebola last week.

There are no direct flights to the U.S. from Mali, and the change will likely affect only 15-20 people who regularly fly in through connecting airports, DHS said in a statement. They will be routed to one of five airports that conduct the enhanced screenings, and they will be subject to 21-day monitoring for symptoms. Most are U.S. citizens or residents who are flying home.

The news out of New York brings the grand total of Ebola cases currently in the U.S. back down to zero.

Dallas's Ebola Scare Is Over

On Friday, November 7, what began with Thomas Eric Duncan's September 30th diagnosis came to an end as the last person being monitored for symptoms of Ebola in Dallas was cleared by officials. The final patient to receive the all-clear was a hospital worker who had handled medical waste on October 17, the New York Times reports. The worker was part of a group of 16 people who had been in contact with Nina Pham and Amber Joy Vinson, nurses who treated Duncan and subsequently came down with the virus themselves. Both have since recovered.

After being monitored twice a day for 21 days, the length of Ebola's incubation period, this last group of people was found to be symptom-free. Most were cleared on Thursday night, and the last person was checked out on Friday. In total, 177 people have had to go through this 21-day watch period since Duncan's diagnosis. In all, the Times says the flare-up of the virus cost Dallas County more than $1 million.

“It’s been a challenge, and there have been moments of frustration throughout this difficult process," Dallas Mayor Mike Rawlings said in a statement. "But the city’s plan and its steadfast commitment to early detection and proper monitoring played a key role in stopping the spread of the virus. And I’m especially thankful to all the brave health care workers who put their lives on the line to help others, including Nina Pham and Amber Vinson, who are true heroes in this city and around the world.”

Quarantine Order On Maine Nurse Is Lifted

Kaci Hickox is free to go.

A Maine judge quickly lifted a temporary order restricting the nurse's movements on Friday, saying only that she had to "coordinate" her travel with state health officials and notify them if she develops any symptoms of Ebola. Judge Charles LaVerdiere's ruling in favor of Hickox came less than a day after he temporarily granted the state's request to enforce her 21-day home quarantine.

Hickox has protested her confinement both in New Jersey and in Maine, arguing that the policies are not medically-sound and violate her civil liberties. After returning a week ago from treating Ebola patients in West Africa, she has tested negative for the virus and exhibited no symptoms. Hickox defied the Maine quarantine on Thursday by going for a bike ride and speaking to reporters outside her house, prompting the governor to seek a court order against her.

LaVerdiere said Hickox must participate in active monitoring of her health with state officials, and while praising her, he gently instructed her to be aware of the public's "real fear" of Ebola.

"The court is fully aware that people are acting out of fear and that this fear is not entirely rational. However, whether that fear is rational or not, it is present and it is real. Respondent's actions, at this point, as a health care professional, need to demonstrate her full understanding of human nature and the real fear that exists. She should guide herself accordingly.

The Associated Press reported that a state police cruiser parked outside her home in Fort Kent drove away after the ruling was issued. Governor Paul LePage said he would not challenge the judge's ruling.

“As governor, I have done everything I can to protect the health and safety of Mainers," he said in a statement. "The judge has eased restrictions with this ruling and I believe it is unfortunate. However, the state will abide by law.”

Judge Grants Order Restricting Quarantined Maine Nurse

A judge in Maine has granted a request by state health officials to temporarily restrict the movement of Kaci Hickox, the nurse who has defied a 21-day quarantine after she returned from treating Ebola patients in West Africa.

The order is only for 24 hours, but it limits her travel and bans her from public places or within three feet of other people outside her home, according to the Associated Press. Hickox left her home in Fort Kent on Thursday to go for a bike ride and then to speak with reporters. She has argued the mandatory quarantine is not based on science and violates her civil liberties. Hickox said she has no fever and therefore could not transmit Ebola even if she had it, because only people with symptoms are contagious. She has about two weeks left on her quarantine.

Hagel Signs Ebola Quarantine Order for Military

Soldiers returning from the military's mission combatting Ebola in West Africa will be placed in a 21-day quarantine under an order signed Wednesday by Defense Secretary Chuck Hagel.

Hagel approved a recommendation from the Joints Chiefs of Staff to create what the military is calling a "controlled monitoring regimen" for service members in the region. The order formalizes a more restrictive Ebola protocol than the CDC recommends for civilian health workers, and Hagel said in an appearance at the Washington Ideas Forum that the move was prompted in part by concerns raised by military families, who "very much wanted a safety valve on this."

Just over 1,000 service members are in Liberia and Senegal, and as many as 4,000 could be part of the mission to build treatment centers and help the local population contain the outbreak. Pentagon spokesman John Kirby said in a statement that the policy would be reviewed after 45 days based on what the military learns from the first wave of returning soldiers.

"The secretary believes these initial steps are prudent given the large number of military personnel transiting from their home base and West Africa and the unique logistical demands and impact this deployment has on the force," Kirby said. "The secretary's highest priority is the safety and security of our men and women in uniform and their families."

Nurse Threatens to Go to Court If State Quarantines Her

Days after being quarantined against her will behind a New Jersey hospital, nurse Kaci Hickox says that she will go to court if Maine tries to impose a quarantine on her. Hickox, who was detained after returning from West Africa, where she was treating Ebola patients, was flown to Maine earlier this week and has been following the state's voluntary quarantine. However, she says, if the restrictions against her aren't removed by Thursday, Hickox says she will go to court.

"I am not going to sit around and be bullied by politicians and forced to stay in my home when I am not a risk to the American public," she said during a televised interview on Today.

Hickox maintains that she is not sick, having twice tested negative for Ebola. Her initial detainment was spurred by a high temperature reading on an airport forehead scanner, although a follow-up reading showed her temperature to be normal. Her case has become something of a lightning rod as political grappling over quarantine policy continues between officials on the state and federal levels.

To anyone who has followed the shadowboxing between federal officials and the governor of New Jersey over the last several days, it was clear to whom Obama was referring when he spoke up repeatedly in defense of health workers who treat Ebola patients in West Africa and insisted that public health policies must not discourage them from fighting the virus at its source.

Second Infected Nurse Is Declared Ebola-Free

Amber Vinson, the second Dallas nurse who contracted Ebola from Thomas Eric Duncan, is now free of the virus and will be released from Emory University Hospital in Atlanta on Tuesday afternoon, the hospital said.

Vinson was transferred to Emory from the Dallas hospital where she treated Duncan, who died October 8. She had flown to Cleveland and back to Dallas in the days before she became symptomatic, but thus far no one with whom she came in contact has been diagnosed with Ebola. Another nurse who treated Duncan, Nina Pham, was released from an NIH hospital in Maryland after being treated successfully for Ebola.

The only person in the U.S. currently known to have Ebola is now Dr. Craig Spencer, who is undergoing treatment in New York.

When she arrives, Power will become the latest face of federal policy with regard to Ebola (whatever it may be by then).

Christie Has 'No Second Thoughts' About Ebola Quarantine

New Jersey Governor Chris Christie on Sunday defended his Ebola quarantine policy, dismissing complaints from a nurse quarantined under the policy, as well as worries that the approach would deter American health workers from traveling overseas to tackle the virus—a stance that has drawn the attention of the White House and could bring legal action against the state.

"The government's job is to protect safety and health of our citizens," Christie said on Fox News Sunday. "I have no second thoughts about it."

Criticism of the quarantine policy started when Kaci Hickox, a nurse placed under mandatory quarantine in New Jersey, slammed the "knee-jerk reaction by politicians" and the policy over how she has been treated during that time in anopinion piece for the Dallas Morning News. On Sunday, she reiterated her position, saying on CNN's "State of the Union," "This is an extreme that is really unacceptable, and I feel like my basic human rights have been violated."

New York, New Jersey Announce New Ebola Quarantines at Airports

The states of New York and New Jersey will begin quarantining all medical workers who treated Ebola patients in West Africa and return to the U.S. through their airports, Governors Andrew Cuomo and Chris Christie announced Friday.

The stepped-up response comes one day after a New York doctor was diagnosed with Ebola about a week after returning from Guinea, where he was working with Doctors Without Borders. Cuomo and Christie said the CDC allows states to determine their own quarantine guidelines, even though the policy will not–as of yet–be in effect nationally. Christie said a health worker who had treated Ebola patients in West Africa was already quarantined at Newark Liberty International Airport earlier Friday under the new policy, even though she did not present any symptoms of the virus.

"This is not the time to take chances," Cuomo said.

He said it was clear voluntary quarantines for workers returning from West Africa were not enough, especially after it emerged that Dr. Craig Spencer, the New Yorker diagnosed with Ebola on Thursday, had gone out and about in public during the 21-day period after he treated patients in Guinea.

Scientists Consider Role of Robots in Caring for Ebola Patients

Ebola is a cruel disease in many ways, but one of the worst is that it preys on the very things that help make us who we are, as a species: our need for community. Our impulse for love. Our inability to see a baby, abandoned, and not reach out. Ebola preys on human bodies, by way of human souls.

From a technological standpoint, the best way to combat all of this is for the healthy to distance themselves from the stricken. And the most obvious way to do that is to remove human interaction from the equation. And the most obvious way to do that may involve removing humans themselves from the equation—at least when it comes to the care of the sick.

On November 7, scientists will convene at universities across the country to consider the role that autonomous machines might play in combating the Ebola crisis. Read more...

Lawmakers Voice Doubts on Ebola Protocols

The Ebola diagnosis in a New York doctor who had returned recently from Guinea is prompting lawmakers to voice fresh concerns about protocols for preventing the spread of the virus in the U.S.

At a hearing on Capitol Hill, several lawmakers questioned whether people who may have been exposed to the virus should be trusted to "self-monitor" themselves during the 21-day period when Ebola could be in their system. Dr. Craig Spencer, the New York doctor, had gone bowling and taken the subway the day before he reported a fever to health officials.

"I am highly skeptical," said Representative Michael Turner, a Republican of Ohio. "The American public is worried. I believe these [standards] need to be revised." He questioned why military service members in West Africa were allowed to travel after just 10 days, rather than wait the full three weeks.

Democratic Representative Steven Lynch of Massachusetts said travelers should be required to spend the 21-day monitoring period abroad before they are allowed to enter the U.S.

"I understand we don’t want to panic people, but we also don’t need happy talk about what we’re dealing with," Lynch said.

"We are not taking this seriously enough. We are not," he added.

Lynch directed questions to Rabih Torbay, a senior official with the International Medical Corps, which is treating Ebola patients in Africa. Torbay said a much longer waiting period would be unworkable for hospitals who need staff on the job. "We cannot completely wrap ourselves in a bubble here," Torbay said.

The chairman of the Oversight Committee, Representative Darrell Issa of California, raised alarmed about the possible spread of Ebola through public transportation, which health experts say is unlikely because the disease is spread only through contact with bodily fluids from a patient presenting symptoms. Issa harshly criticized CDC director Dr. Thomas Frieden (who was not present) and suggested that contrary to his public statements, Ebola could easily be transmitted on public transportation if, for example, an infected person vomited on a bus.

"When the head of the CDC says you can't get it on a bus from someone sitting next to you, that's just not true," Issa said. "The fact is the head of the CDC gave false information."

First infected Dallas Nurse Declared Free of Ebola

Nina Pham, one of the two nurses who contracted Ebola in Dallas, will be released from an National Institutes of Health facility in Maryland on Friday after medical officials there declared her to be free of the virus. She was admitted on October 16.

Pham was the first nurse infected after treating Thomas Eric Duncan, the Liberian man who died in Dallas earlier this month. The second nurse, Amber Vinson, is also improving and was told by doctors at Emory University Hospital in Atlanta on Wednesday that the virus could no longer be detected in her bloodstream.

Doctor in New York City Diagnosed with Ebola

A doctor who treated Ebola victims in Guinea has been diagnosed with the virus in New York, in the first U.S. case confirmed outside of Dallas.

Dr. Craig Spencer was rushed to Bellevue Hospital Center in Manhattan on Thursday after he called authorities and reported a fever and gastrointestinal symptoms. An initial blood test came back positive for Ebola.

Spencer is the fourth person in the U.S. to be diagnosed with Ebola. The first case, Thomas Eric Duncan, died in Dallas earlier this month, and two nurses who treated him have become infected. One of those nurses, Amber Vinson, was cleared of the virus on Wednesday. Spencer's diagnosis is likely to cause concern in New York because he traveled on the subway and went to a bowling alley in Brooklyn on the night before he came down with a fever. Spencer, 33, worked with Doctors Without Borders in Guinea and returned to the U.S. a week ago, officials said Thursday night.

The CDC has dispatched a rapid response team to New York, and "disease detectives" were trying to reach people who had come in contact with Spencer in recent days. CDC director Dr. Thomas Frieden said that by coincidence, the center already had a team in New York observing Bellevue's preparations for a possible case.

City and state officials immediately sought to head off a public panic at the first case of Ebola in the nation's largest and densest city. "We want to state at the outset that there is no reason for New Yorkers to be alarmed," New York Mayor Bill de Blasio said in a nationally-televised press conference.

The city's health commissioner, Dr. Mary Bassett, said Spencer had felt fatigued in recent days but did not have a fever until Thursday morning. He had been checking his temperature twice a day since returning from West Africa. Three of Spencer's contacts will be monitored for symptoms for 21 days, Bassett said.

New Standards for Protective Gear

The CDC will soon release stricter standards for personal protective gear for American hospital workers handling suspected Ebola patients.

Dr. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, said this weekend that the new rules will require full-body suits that leave no skin exposed, as well as a "site manager" to oversee workers as they don and remove gear.

The earlier rules allowed for some degree of variation between hospitals and were designed for field work in Africa. "So there were parts about that protocol that left vulnerability, parts of the skin that were open," Fauci told the AP.

Healthcare workers will also have to practice getting in and out of the protective gear.

White House Describes Ron Klain as 'Implementation Expert'

Understandably, the White House is not calling Ron Klain a "czar." Officially, Klain will be known as the "Ebola response coordinator," press secretary Josh Earnest told reporters on Friday.

"As far as I'm concerned, you can call him anything you want. We call him the Ebola response coordinator," Earnest said.

President Obama appointed Klain, a former chief of staff to two vice presidents, to oversee the government's response to the outbreak in West Africa and the virus's spread in the United States. Republicans have already criticized the pick, noting that Klain has no medical or public health expertise. Earnest quipped that it was a "shocking development" that GOP lawmakers would oppose a presidential decision three weeks before an election.

More seriously, Earnest said Obama was not looking for an "Ebola expert" but an "implementation expert" who could guide a whole-of-government response to the crisis. He cited Klain's experience, while working for Vice President Biden, in coordinating the implementation of the 2009 economic stimulus package.

"We think he is exceedingly well-suited to the task," Earnest said. "His area of expertise is in implementation, and that is exactly what is needed."

Klain is not on the job yet, but he will start soon.

On the question of a travel ban, Earnest continued to argue against the policy change, saying it could produce a "perverse" effect by incentivizing travelers from West Africa to seek other ways into the country. Governor Rick Perry of Texas joined other Republicans in calling for tighter restrictions on Friday.

Nurses Say Their Hospitals Did Not Prepare Them for Ebola

Now that two nurses have contracted Ebola, nurses' groups around the country blame their hospitals and the CDC for not providing adequate protective gear or training staff in how to use it.

Lynda Pond, a labor and delivery nurse in Springfield, Oregon, told The Atlantic:

None of [the rooms] have antechambers for donning and removing isolation gear. A "cart" with paper gowns, gloves, and non-specific masks is parked outside the door. The nurse [puts on] gowns and gloves outside the room, enters the room, provides care and removes the equipment at the door prior to exiting, placing it in a garbage bin inside the room ... To my knowledge there is not adequate supply of full hazmat suits, there are not instructions for gloving, taping and gloving again. Nor are there leggings or shoe covers as part of the standard isolation gear.

Texas Health Worker Under Watch for Ebola Is on Cruise Ship

The State Department is seeking the return to the U.S. of a Texas health worker who boarded a cruise ship after handling clinical specimens from Thomas Eric Duncan, the Ebola patient who died in the U.S. last week.

Jennifer Psaki, a State Department spokeswoman, said in a statement early Friday that the unnamed employee of the Texas Health Presbyterian Hospital left on a cruise ship from Galveston on October 12, before the CDC stepped up its monitoring requirements after two nurses who treated Duncan were diagnoses with Ebola.

"The employee did not have direct contact with the since deceased Ebola patient, but may have had contact with clinical specimens collected from him," Psaki said.

The health worker has been placed in isolation on the ship, and a doctor aboard the vessel said she was "in good health," according to the State Department. "We are working with the cruise line to safely bring them back to the United States out of an abundance of caution," Psaki said.

Yet that may be more difficult, because the government of Belize said in a statement posted on Facebook that it had denied a U.S. request to evacuate the worker through Philip Goldson International Airport in Belize City "out of an abundance of caution." The statement made clear to the public that "the passenger never set foot in Belize."

Obama Opens Door to Travel Ban, Ebola 'Czar'

Is President Obama changing his mind on a possible travel ban from the three West African countries caught up in the Ebola epidemic?

The president told reporters after a meeting on the outbreak Thursday evening that he did not have any "philosophical objections necessarily" to travel restrictions but that his experts had told him it would be less effective than the screening measures currently in place. It marked a shift, at least in tone, from previous statements, when the White House and senior health officials said a ban was not under consideration. Calls for a ban have grown in recent days, particularly from Republicans.

Obama also signaled he might appoint an Ebola "czar" to oversee the government's response to the crisis. He noted that the CDC director, Dr. Thomas Frieden, and his senior counterterrorism adviser, Lisa Monaco, had other responsibilities even as they have taken the lead in handling Ebola.

"So it may make sense for us to have one person, in part just so that after this initial surge of activity we can have a more regular process just to make sure that we’re crossing all the T’s and dotting all the I’s going forward," the president said.
