That question is not easy to answer. The more obvious answer is that airborne transmission is already taking place.
The transmission of Ebola to expert medical staff has been commonplace. The two American Ebola experts that came back to America with Ebola, being just one example. With US military personnel on their way to the worst Ebola areas in Africa, this question needs to be answered.
President Obama said Tuesday the United States will launch a major, military-led, response in West Africa to the deadly Ebola outbreak that has reached epidemic proportions and now poses “a potential threat to global security.”
Obama announced the stepped-up effort against the virus, which has killed at least 2,400 people in five West African countries, at the Centers for Disease Control and Prevention in Atlanta.
“It’s spreading out of control,” Obama said. “We have to act fast. We cannot dawdle on this one. We have to move with force.”
Published reports earlier in the day said Obama would announce that he was sending 3,000 military personnel. But he did not say in his roughly 15-minute announcement how many people would be deployed. http://www.foxnews.com/politics/2014/09/16/president-obama-announces-plan-for-ebola/
Another example of experts getting it? A hospital was shut down because so many of the medical staff caught and died from Ebola:
Ebola Shuts Down The Oldest Hospital In Liberia
But in the Liberian capital Monrovia, Ebola has silenced St. Joseph’s Catholic Hospital. It is completely shut.
Samuel Bowman, 72, is the medical director of the facility. When we met today outside his living quarters at the back of the hospital compound, Bowman had just heard on the radio that Father Miguel Pajares, a Spanish priest who worked at St. Joseph’s and contracted Ebola, had died in a Madrid hospital, where he’d been evacuated.
Bowman says St. Joseph’s wasn’t even supposed to treat Ebola patients, but some ended up on its wards. “In the process, our hospital director became infected by one of the patients,” Bowman says. “He has subsequently died. And those who had direct contact with him. They got infected.”
Bowman counts off on his fingers those others infected: “A brother, two sisters, two of our staff nurses, the social worker. And a laboratory technician.” http://www.npr.org/blogs/ebola-shuts-down-the-oldest-hospital-in-Liberia
The question of air transmission has been suppressed. It is known that it can occur. An AUN-TV article earlier in the outbreak said this:
The second possibility is one that virologists are loath to discuss openly but are definitely considering in private: that an Ebola virus could mutate to become transmissible through the air. You can now get Ebola only through direct contact with bodily fluids. But viruses like Ebola are notoriously sloppy in replicating, meaning the virus entering one person may be genetically different from the virus entering the next. The current Ebola virus’s hyper-evolution is unprecedented; there has been more human-to-human transmission in the past four months than most likely occurred in the last 500 to 1,000 years. Each new infection represents trillions of throws of the genetic dice. Read More: http://www.nytimes.com/2014/09/12/opinion/what-were-afraid-to-say-about-ebola.html?_r=0
In a 2012 scientific study reported in Nature in 2012, the most serious strain Ebola Zaire was proven to travel without contact with any bodily fluids. Ebola Zaire jumped through the air from infected piglets to macaque monkeys in a proven experimental context. One should recall that the virus originated in monkeys and jumped to humans. “All it takes is one cough, one sneeze, one drop of saliva, and the virus is loose in one of the main transportation centers of the U.S.,” journalist Paul Craig Roberts wrote.
Contact with bodily fluids was not required for transmission of the infection in the Reston incident. On October 4, 1989, Ebola-infected monkeys from the Philippines (a crab-eating type of macaque) were imported as laboratory animals into Reston, Virginia, only 22 miles from The White House in the populated business center straddling major commuting routes straight into the Nation’s Capitol. “The Ebola Reston virus jumped quickly from room to room… Ebola apparently drifted through the building’s air-handling ducts.” Ileana Johnson reports.
Two (2) of the 100 monkeys arrived dead in their crates when the Ebola-infected animals arrived at the monkey house called the Reston Primate Quarantine Unit operated by Hazelton Research Products, a division of Corning, Inc. Within 6 weeks, 29 more died. It took nearly 7 weeks for an intern Thomas Geisbert to discover that the cause was Ebola — in fact, a new Ebola, Reston, a mutated strain of Ebola Zaire. Two monkey handlers got sick, one had a heart attack and another one was sent to the Fairfax Hospital with flu like symptoms and vomiting. http://aun-tv.com/ebola-already-in-the-usa-across-mexican-border-doctor-alleges/
Typical Ebola Protective Gear in Africa includes Goggles
The fact that so many doctors with protective gear have contacted Ebola, is a sign they got it through the air.
Doctor Bob Arnot, who has treated Ebola in Africa, in the below video tells how he saw first hand a case of airborne droplet transmission that killed a fellow doctor. Droplet transmission such as in a cough is less dangerous than the apparent Reston air conditioning system transmission method mentioned above. However it is far more dangerous than the CDC and Obama’s claim of “direct contact with bodily fluids” implies.
