Well I don't know if it was true or false. Sometimes things get pulled and refuted when in fact were true.
Here in the U.S.: Different confusion. Different questions. for example, if Ebola is not airborne, why the extraordinary precautions for Dr. Brantley and Ms. Whitebol?
It turns out standard precautions may suffice.

Droplet and respiratory precautions.
And while I suited up in multiple layers when I was in Guinea earlier this year, the CDC says a mask, goggles to protect eyes or a face shield to protect the face, a protective gown to prevent bodily fluids from covering clothes and arms and gloves can provide protection for most situations.
The WHO is currently meeting and could announce a public health emergency on Friday - that would add even more urgency at the CDC's nerve center here in Atlanta.

Unlike facemasks, respirators form a tight seal to the face. Respirators typically refer to CDC-certified N95 or higher filtering face pieces (meaning that they filter out 95% of airborne particles). They are primarily manufactured for use in construction and industrial jobs that expose workers to dust and small airborne particles.1 In order for respirators to be effective, they must be fitted properly according to the Occupational Safety and Health Administration (OSHA) guidelines.5 Respirators are harder than facemasks to breathe through for extended periods of time and can cause skin irritation. CDC guidelines do not suggest respirators for children or people with facial hair.
II.E.3. Face protection: masks, goggles, face shields II.E.3.a. Masks are used for three primary purposes in healthcare settings: 1) placed on healthcare personnel to protect them from contact with infectious material from patients e.g., respiratory secretions and sprays of blood or body fluids, consistent with Standard Precautions and Droplet Precautions; 2) placed on healthcare personnel when engaged in procedures requiring sterile technique to protect patients from exposure to infectious agents carried in a healthcare worker's mouth or nose, and 3) placed on coughing patients to limit potential dissemination of infectious respiratory secretions from the patient to others (i.e., Respiratory Hygiene/Cough Etiquette). Masks may be used in combination with goggles to protect the mouth, nose and eyes, or a face shield may be used instead of a mask and goggles, to provide more complete protection for the face, as discussed below. Masks should not be confused with particulate respirators that are used to prevent inhalation of small particles that may contain infectious agents transmitted via the airborne route as described below. Masks should not be confused with particulate respirators that are used to prevent inhalation of small particles that may contain infectious agents transmitted via the airborne route as described below.
II.E.4. Respiratory protection The subject of respiratory protection as it applies to preventing transmission of airborne infectious agents, including the need for and frequency of fit-testing is under scientific review and was the subject of a CDC workshop in 2004 763. Respiratory protection currently requires the use of a respirator with N95 or higher filtration to prevent inhalation of infectious particles. Information about respirators and respiratory protection programs is summarized in the Guideline for Preventing Transmission of Mycobacterium tuberculosis in Health-care Settings, 2005 (CDC.MMWR 2005; 54: RR-17 12). Respiratory protection is broadly regulated by OSHA under the general industry standard for respiratory protection (29CFR1910.134)764 which requires that U.S. employers in all employment settings implement a program to protect employees from inhalation of toxic materials. OSHA program components include medical clearance to wear a respirator; provision and use of appropriate respirators, including fit-tested NIOSH-certified N95 and higher particulate filtering respirators; education on respirator use and periodic re-evaluation of the respiratory protection program. When selecting particulate respirators, models with inherently good fit characteristics (i.e., those expected to provide protection factors of 10 or more to 95% of wearers) are preferred and could theoretically relieve the need for fit testing 765, 766. Issues pertaining to respiratory protection remain the subject of ongoing debate. Information on various types of respirators may be found at www.cdc.gov/niosh/npptl/respirators/respsars.html and in published studies 765, 767, 768. A user-seal check (formerly called a "fit check") should be performed by the wearer of a respirator each time a respirator is donned to minimize air leakage around the facepiece 769. The optimal frequency of fit-testng has not been determined; re-testing may be indicated if there is a change in facial features of the wearer, onset of a medical condition that would affect respiratory function in the wearer, or a change in the model or size of the initially assigned respirator 12. Respiratory protection was first recommended for protection of preventing U.S. healthcare personnel from exposure to M. tuberculosis in 1989. That recommendation has been maintained in two successive revisions of the Guidelines for Prevention of Transmission of Tuberculosis in Hospitals and other Healthcare Settings 12, 126. The incremental benefit from respirator use, in addition to administrative and engineering controls (i.e., AIIRs, early recognition of patients likely to have tuberculosis and prompt placement in an AIIR, and maintenance of a patient with suspected tuberculosis in an AIIR until no longer infectious), for preventing transmission of airborne infectious agents (e.g., M. tuberculosis) is undetermined. Although some studies have demonstrated effective prevention of M. tuberculosis transmission in hospitals where surgical masks, instead of respirators, were used in conjunction with other administrative and engineering controls 637, 770, 771, CDC currently recommends N95 or higher level respirators for personnel exposed to patients with suspected or confirmed tuberculosis. Currently this is also true for other diseases that could be transmitted through the airborne route, including SARS 262 and smallpox 108, 129, 772, until inhalational transmission is better defined or healthcare-specific protective equipment more suitable for for preventing infection are developed. Respirators are also currently recommended to be worn during the performance of aerosol-generating procedures (e.g., intubation, bronchoscopy, suctioning) on patients withSARS Co-V infection, avian influenza and pandemic influenza (See Appendix A). Although Airborne Precautions are recommended for preventing airborne transmission of measles and varicella-zoster viruses, there are no data upon which to base a recommendation for respiratory protection to protect susceptible personnel against these two infections; transmission of varicella-zoster virus has been prevented among pediatric patients using negative pressure isolation alone 773. Whether respiratory protection (i.e., wearing a particulate respirator) would enhance protection from these viruses has not been studied. Since the majority of healthcare personnel have natural or acquired immunity to these viruses, only immune personnel generally care for patients with these infections 774-777. Although there is no evidence to suggest that masks are not adequate to protect healthcare personnel in these settings, for purposes of consistency and simplicity, or because of difficulties in ascertaining immunity, some facilities may require the use of respirators for entry into all AIIRs, regardless of the specific infectious agent. Procedures for safe removal of respirators are provided (Figure). In some healthcare settings, particulate respirators used to provide care for patients with M. tuberculosis are reused by the same HCW. This is an acceptable practice providing the respirator is not damaged or soiled, the fit is not compromised by change in shape, and the respirator has not been contaminated with blood or body fluids. There are no data on which to base a recommendation for the length of time a respirator may be reused.
Just look at their 'script'.
"We're pretty confident that any large hospital could handle an Ebola case using traditional isolation rooms with negative pressure room and with traditional, Stephan Monroe, the Centers for Disease Control and Prevention said.
Following the introduction of Ebola virus in the human population through animal-to-human transmission, person-to-person transmission by direct contact bodily fluids/secretions of infected persons is considered the principal mode of transmission. Indirect contact with environment and fomites soiled with contaminated bodily fluids (e.g. needles) may also occur. Airborne transmission has not been documented during previous EVD outbreaks.
There is no risk of transmission during the incubation period.
...efforts to control the outbreak are hampered by...the facts that chains of transmission have moved underground making meticulous early detection and isolation of cases, contact tracing and monitoring – the cornerstone of EVD control – difficult to be carried out.
If the patient with illness compatible to EVD develops symptoms while on an aircraft, contact tracing must be made according to the Risk assessment guidelines for diseases transmitted on aircraft (RAGIDA) protocol1, which indicates contact tracing of all those passengers seated within 4 rows ahead and 4 rows behind, as well as the crew on board. If the cleaning of the aircraft is performed by unprotected personnel, they should be considered as contacts. Contacts should be assessed in a designated area within the airport according to the airport contingency plan.

Aug 8 (Reuters) - West Africa's Ebola epidemic is an "extraordinary event" and now constitutes an international health risk, the World Health Organisation (WHO) said on Friday. The Geneva-based U.N. health agency said the possible consequences of a further international spread of the outbreak, which has killed almost 1,000 people in four West African countries, were "particularly serious" in view of the virulence of the virus. "A coordinated international response is deemed essential to stop and reverse the international spread of Ebola," the WHO said in a statement after a two-day meeting of its emergency committee on Ebola.
The declaration of an international emergency will have the effect of raising the level of vigilance for transmission of the virus. The agency added that while all states with Ebola transmission - so far Guinea, Liberia, Nigeria and Sierra Leone - should declare a national emergency, there should be no general ban on international travel or trade. Keiji Fukuda, the WHO's head of health security, stressed that, with the right steps and measures to deal with infected people, Ebola's spread could be stopped. "This is not a mysterious disease. This is an infectious disease that can be contained," he told reporters on a telephone briefing from the WHO's Geneva headquarters. "It is not a virus that is spread through the air."
The WHO said the current outbreak was the most severe in the almost 40 years since Ebola was first identified in humans. This was partly because of weaknesses in the countries currently affected, it said, where health systems were fragile and lacking in human, financial and material resources. It also said inexperience in dealing with Ebola outbreaks and misperceptions of the disease, including how it is transmitted, "continue to be a major challenge in some communities". Although most cases of Ebola are in the remote area where Guinea borders Sierra Leone and Liberia, alarm over the spread of the disease increased last month when a U.S. citizen died in Nigeria after travelling there by plane from Liberia.
After an experimental drug was administered to two U.S. charity workers who were infected in Liberia, Ebola specialists have urged the WHO to offer such drugs to Africans. The U.N. agency has asked medical ethics experts to explore this option next week.
