In order to better understand how filoviruses are transmitted, the team tested several strains of Ebola, including the ZEBOV (Zaire ebolavirus) species currently believed to be in circulation, to see how they survived under various conditions. Both the ZEBOV and MARV (Lake Victoria marburgvirus) strains were tested for survival rates in liquid suspensions and on plastic, glass and metal surfaces for multiple established time periods, as well as in dynamic aerosols (airborne).
According to the Daily Mail Online, both the ZEBOV and MARV strains were tested on glass, metal and plastic at 4 degrees Celsius (39 degrees Fahrenheit) or room temperature for several weeks. Plotted charts contained in the study show the survival rates of the viruses in the different media. While both viruses were found to survive for 26 days on the cold plastic, ZEBOV survived for nearly two months, or 50 days, on the chilled glass.
At no point in the study were scientists able to obtain a sample of either virus from the metal substrate, made from stainless steel.
"This study has demonstrated that filoviruses are able to survive and remain infectious for cell culture, for extended periods when suspended within liquid media and dried onto surfaces," wrote the researchers about their findings. "Data from this study extend the knowledge on the survival of filoviruses under different conditions and provide a basis with which to inform risk assessments and manage exposure."

Government lies again: Ebola can be transmitted by touching contaminated surfaces
Though real-world conditions vary from those in a laboratory, these findings suggest that, once again, the U.S. government has lied to the public about the dangers of Ebola. If it is really true that Ebola can survive on dry surfaces where it would be impossible for the virus to incubate, then the risk of disease transmission is much higher than we are all being told.The U.S. Centers for Disease Control and Prevention (CDC), along with the Obama White House, continues to claim that Ebola is not spread through air, water or food, and that it only transmits from an infected person through direct contact with his or her bodily fluids. But this study of Ebola survival on surfaces suggests that these reassurances by the government are false.
Besides its surface transmission potential, Ebola can also travel through the air via aerosol particulates, such as those expelled when a person coughs or sneezes. This was confirmed in a recent Massachusetts Institute of Technology (MIT) study which found that Ebola-contaminated micro-droplets can travel as far as 20 feet from an infected person, potentially distributing throughout a hospital's ventilation system, for instance.
"[C]oughs and sneezes have associated gas clouds that keep their potentially infectious droplets aloft over much greater distances than previously realized," explains the MIT study, the announcement for which is available through MIT News:
NewsOffice.MIT.edu.
"[T]he smaller droplets that emerge in a cough or sneeze may travel five to 200 times further than they would if those droplets simply moved as groups of unconnected particles -- which is what previous estimates had assumed. The tendency of these droplets to stay airborne, resuspended by gas clouds, means that ventilation systems may be more prone to transmitting potentially infectious particles than had been suspected."
