CDC Concerned About Airborne Transmission of Ebola Virus
Federal agency directs airline staff to prevent spread of “infectious material through the air”
Despite repeated assurances that the Ebola virus cannot be transmitted via airborne particles, the CDC is concerned about that very outcome and has directed airline staff to take steps to prevent the spread of “infectious material through the air.”
While Ebola is highly contagious, the risk of a full blown pandemic has been downplayed by health authorities because, according to our current understanding of the virus, Ebola, “is not airborne and is transmitted through contact with bodily fluids, including sweat and blood.”
However, with concerns rising that the current strain of the virus, which is the worst in history and has killed 887 people, could in fact be airborne, the Centers For Disease Control has implemented steps to prevent its spread via international air travel.
A CDC advisory entitled Interim Guidance about Ebola Virus Infection for Airline Flight Crews, Cleaning Personnel, and Cargo Personnel reveals that the federal agency is concerned about airborne contamination.
The advisory urges airline staff to provide surgical masks to potential Ebola victims in order “to reduce the number of droplets expelled into the air by talking, sneezing, or coughing.” (emphasis mine).
The CDC is also directing airline cleaning personnel to, “not use compressed air, which might spread infectious material through the air.” (emphasis mine).
The CDC’s concern about the Ebola virus being spread via the air is understandable in light of a 2012 experiment conducted by Canadian scientists which proved that, “the ebola virus could be transmitted by air between species.”
Researchers demonstrated that the virus could be transmitted from pigs to monkeys without any direct contact by placing the two animals in pens separated only by a wire barrier. After eight days, some of the monkeys were found to have symptoms of Ebola likely as a result of “inhaling large aerosol droplets produced from the respiratory tracts of the pigs.”
The results of the study led scientists to conclude that, “limited airborne transmission might be contributing to the spread of the disease in some parts of Africa,” although they cautioned against making comparisons to the airborne nature of the influenza virus.
In addition, the Public Health Agency of Canada’s official website states under a section entitled “mode of transmission,” that “airborne spread among humans is strongly suspected, although it has not yet been conclusively demonstrated.”
The potential for a new strain of the Ebola virus to have achieved airborne transmission only serves to cast further doubt on the logic of the United States choosing to import two Ebola sufferers into the country.
As we reported last week, President Barack Obama signed an amendment to executive order which allows health authorities to detain Americans who merely show signs of respiratory illness.
The CDC has also outlined measures for dealing with an outbreak of a communicable disease which allow for the quarantine of “well persons” who “do not show symptoms” of the disease.
