Luck has kept Ebola out of the U.S. But thats very likely to change.

Only a fluke of timing prevented Kent Brantly from being in Texas when he got sick with Ebola.
Brantly, the first U.S. doctor to get Ebola, was infected in late July while working at a missionary hospital in Liberia. But he didnt immediately realize he was ill. Thats one of Ebolas tricks: The virus can take three weeks to appear, although severe signs usually strike within 10 days. Still, thats time enough for someone to jump on a plane and fly around the world.
So Brantly was already infected with Ebola but not yet sick and thus not yet contagious when, on July 20, his wife and children flew from Liberia to Texas for a wedding. The doctor was scheduled to meet them in Texas a week later. He never made that flight. He fell sick three days later. An Ebola diagnosis followed. He soon made a high-security medical evacuation to Emory University Hospital in Atlanta where he eventually recovered.
But Brantly came exceedingly close to returning to the United States with Ebola. As a doctor, he wouldve taken precautions to prevent anyone else from getting sick. However, the resulting panic Ebola in Texas! might have been impossible to contain.
A bit of luck was involved there.
And that luck seems to be holding six months into the worst Ebola outbreak in history.
Not a single reported Ebola case has made the leap from the West African outbreak to the United States or Europe or Asia or Australia. Only two nations, Senegal and Nigeria, have seen any Ebola cases slip out of the viruss hot zone centered on Sierra Leone, Liberia and Guinea.
Maintaining this lucky streak will only get more difficult and soon impossible as the outbreak grows exponentially.
It is not unexpected that we are lucky so far, said professor Alessandro Vespignani at Northeastern University, who runs a model projecting Ebolas spread. Theres about a 10 percent chance of a single Ebola case getting imported to the United States in the next week. The problem is what will happen in October, when we will likely have a much larger probability. {or November, or during the holiday travel season..}
And if the epidemic reaches anything close to 1.4 million cases, the worst-case projection for four months out, then Ebola in the United States becomes a near-certainty. That doesnt mean an outbreak, but at least one case.
Calculating the odds that Ebola will spread is complex. It involves a bit of guesswork and lots of big data for example, the number of international flights passing through the hot zone and the number of seats on those jets and the chances that any one of those seats will be taken by someone with an early, undetected Ebola infection. {it's a simple math problem, as long as the planes fly}
The odds also reflect policy choices. Those choices can alter odds dramatically.
This is different than the probability of rain this weekend, Vespignani said. We can affect the probability that Ebola will spread.
So you can close borders. Cancel international flights. Step up pre-boarding screenings for fever, the viruss earliest sign. All of these things have been tried in varying degrees. The World Health Organization has pushed countries to maintain flights and open borders, but with screening procedures. So far, those efforts have been effective, a WHO representative said.
The best defense might seem to go further.
But you cant seal off the world, Vespignani said.
Cutting off all access means help cant reach people in the outbreak. No doctors. No surgical gloves. No biohazard suits. So the virus would spread even faster. That would push the odds of Ebola escaping higher.
These things compensate, said Vespignani.
Another Ebola model is run by Dirk Brockmann at the Robert Koch Institute in Berlin. His team found that the probability, for example, that an infected person will board a flight from Freetown, Sierra Leone, and arrive in the United Kingdom is about 7 percent. For the United States, its 1.5 percent. Those odds might sound high, but as Brockmann explains, they mean that 67 infected individuals would need to board a plane for one of them to reach the United States. This is indeed small, Brockmann said.
The problem is that the odds are getting lower. The lucky streak can not continue if the epidemic is not brought under control.
When Brantly was infected, there were only about 1,000 Ebola cases.
And he nearly got to Texas.
Now, just two months later, there have been nearly 5,900.
That number could quadruple to 20,000 by early November, health officials said.
The probability, Vespignani said, is increasing week by week.
Nurses stage Ebola ‘die-in’ on Las Vegas Strip

LAS VEGAS
U.S. hospitals aren't ready for an Ebola outbreak, according to nurses who staged a “die-in” Wednesday outside a Las Vegas Strip resort where they were holding a union convention.
Many protesters in the crowd of about 1,000 who attended the Planet Nurse convention wore bright red T-shirts and suits resembling hazardous-materials gear as they streamed through the Planet Hollywood casino floor before crossing Las Vegas Boulevard to the Bellagio resort.
Ebola “can easily come to our shores, and we're not ready,” said Julia Scott, a registered nurse from Largo Medical Center in Florida who was attending the California Nurses Association and National Nurses United convention.
At the sound of a gong, Scott and dozens of other protesters dropped to the sidewalk in front of the iconic Bellagio fountain, where others used chalk to outline their “dead” bodies, writing the hashtag #StopEbolaRNRN inside the tracings.
It was followed by a moment of silence for international health workers who have died while caring for Ebola patients in West Africa.
“It's not acceptable that these people are dying,” RoseAnn DeMoro, executive director of National Nurses United, told her fellow protestors.
U.S. policymakers are in denial, DeMoro said. “It is going to come here,” she said.
Union representatives called the protest a “die-in.” They pointed to a recent case of a patient tested for Ebola at a northern California hospital.
In that case, the Kaiser Permanente South Sacramento Medical Center ruled out the Ebola virus. Union nurses complained the patient was in contact with health workers in a public waiting area for about a half-hour.
Dr. Stephen M. Parodi, an infectious-disease specialist and hospital operations director for Kaiser Permanente Northern California, said in a statement Wednesday that as soon as Ebola was suspected, the hospital began to inform its entire staff.
“From triage and until it became clear that there was no Ebola infection involved, we took all appropriate precautions, following CDC guidelines, to protect the safety of everyone at our South Sacramento hospital,” he said.
Roslyne Schulman, policy director for the American Hospital Association, said the group's members have been encouraged to follow the federal Centers for Disease Control’s recommendations on infectious diseases such as Ebola.
“Hospitals are prepared to handle a broad range of infectious diseases. When there is a potential risk for particular infections in communities such as Ebola hospitals alert their clinical staff to increase surveillance for symptoms and risk factors associated with the specific disease,” she said in an emailed statement.
The federal Centers for Disease Control announced Tuesday that the number of Ebola cases in Africa could grow from an estimated 21,000 now to 1.4 million in just two African countries by January. Four Americans have been or are being treated for Ebola in the U.S. after evacuation from Africa.
Valerie Loza, a protester and registered nurse at Mountainview Hospital in Las Vegas, said she feared local hospitals wouldn't be ready if Ebola reached the city.
“I'm the first line of defense,” she said. “You don't know what could happen here.”
