Scientists May Prove Ebola Can Spread By Air

Scientists do not exclude the possibility of Ebola virus
transmission by air through aerosolised particles.
It was commonly considered that the deadly disease is
transmitted human-to-human through direct contact with
infected patients or through contact victim’s body fluids.
However the fresh studies suggest another possible
development.
The fears appeared in the case of Patrick Sawyer travelling to
Nigeria who got infected with the virus and died at a hospital in
Lagos. Therefore, implications of the possibility of Ebola
transmission in an enclosed environment, such as an aircraft
cabin, have emerged.
Studies showed that Ebola virus is transmissible to monkeys
from infected pigs without them coming into direct contact. The
Ebola virus survives for days outside infected hosts and can
"ride" on aerosolised droplets to spread to potential victims.
To demonstrate this, Canadian scientists housed the pigs
carrying the virus in pens with the monkeys in close proximity,
but separated by a wire barrier. In 8 days some monkeys started
experiencing symptoms associated with Ebola. Which suggests
aerosolised organisms can possibly cause infection.
According to the Canadian Public Health Agency:
"The virus can survive in liquid or dried material for a number of
days. Infectivity is found to be stable at room temperature or at
4 degrees Celsius for several days, and indefinitely stable at -70
degrees Celsius. Infectivity can be preserved by lyophilisation.
Hence, it is implied that Ebola viruses can survive for several
days on common objects such as door knobs or household
surfaces. If an infected Ebola victim runs around touching such
common objects after cleaning blood or mucous from his nose,
another innocent victim can easily infect himself by touching the
same objects and then eating some food that places the virus in
his mouth."
The currently incurable disease has already claimed hundreds of
lives in Liberia, Guinea and Sierra Leone.
