Tests reveal Ebola can survive on some surfaces for up to 2 months

October 2014HEALTHThe number of confirmed Ebola cases passed the 10,000 mark over the weekend, despite efforts to curb its spread. And while the disease typically dies on surfaces within hours, research has discovered it can survive for more than seven weeks under certain conditions. During tests, the UK’s Defense Science and Technology Laboratory (DSTL) found that the Zaire strain will live on samples stored on glass at low temperatures for as long as 50 days. This family includes the Zaire ebolavirus (Zebov), which was first identified in 1976 and is the most virulent; Sudan ebolavirus, (Sebov); Tai Forest ebolavirus; Ebola-Reston (Rebov), and Bundibugyo ebolavirus (Bebov) – the most recent species, discovered in 2008. For their 2010 paper, ‘The survival of filoviruses in liquids, on solid substrates and in a dynamic aerosol’, Sophie Smither and her colleagues tested two particular filoviruses on a variety of surfaces. These were the Lake Victoria marburgvirus (Marv), and Zebov. Each was placed into guinea pig tissue samples and tested for their ability to survive in different liquids, and on different surfaces at different temperatures, over a 50-day period. When stored at 4° (39°F), by day 26, viruses from three of the samples were successfully extracted; Zebov on the glass sample, and Marv on both glass and plastic.
By day 50, the only sample from which the virus could be recovered was the Zebov from tissue on glass. ‘This study has demonstrated that filoviruses are able to survive and remain infectious, for extended periods when suspended within liquid and dried onto surfaces,’ explained the researchers. ‘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.’ The researchers do stress that these tests were carried out in a controlled lab environment, and not in the real world, but published their findings to highlight the survival rates. Last week the Centers for Disease Control and Prevention (CDC) updated its Ebola guidelines following the rise in infections. –Daily Mail

    This Ebola containment fiasco gets more bizarre everyday. Why won’t the CDC, White House & medical establishment admit they don’t know or are uncertain. Then err on the side of an abundance of caution to protect the public. I’m with the military & those states that have implemented mandatory 21 quarantines. I am not panicking or hysterical. Just getting more alarmed & angry at the ineptitude from officials & “experts”. When the public loses faith in it’s government & official pronouncements you get what we see now…chaos.

    In Canada, experiments have been conducted that show Ebola can be aerosol borne…droplets small enough to be carried on the air. Research the following: Dr. Gary Kobinger, Public Health Agency of Canada, University of Manitoba, National Center for Foreign Animal Disease, The Daily Disease, “From Pigs to Monkerys, Ebola Goes Airborne.”

    ok , fair enough scientists , ……… but …… no one gives a stuff about lab conditions , its real conditions these scientists should be studying , what a tragic and usless waste of valuable time with a deadly disease raging , they are so smart it hurts !!

    Surely after all these studies it is only common sense that the bodies should be cremated, regardless of religious or personal preference. By burying the corpse, it is only an ‘out of sight, out of mind’ answer, what about reconstitution in water when it rains and where does the water run off drain into? rivers, creeks, puddles, up to the surface where people are walking or to be unburied eons down the track. Please, please, please BURN THE BODIES, in-fact exhume the buried and burn them all. One should NEVER bury disease and that goes for anyone who dies of anything infectious – it should be made mandatory.

      Found this hopefully reassuring bit…
      It has been said,
      (at least by these two virologists)
      that ebolavirus does not survive long in water- “…deactivated in a matter of minutes”:
      http://www.npr.org/blogs/goatsandsoda/2014/09/12/346114454/how-do-you-catch-ebola-by-air-sweat-or-water
      “Can Ebola be spread through a drop of water or carried through the water system?
      “[The virus] will not remain for a long time in the water,” Gonzalez says. “It’s not a very rich medium to protect the virus.”
      It’s important, he adds, to remember that viruses aren’t as resistant outside the body as bacteria are. Rather, they depend heavily on the cells of their host — animal or human — for survival.
      In water, the Ebola virus would be deactivated in a matter of minutes, Schmaljohn says. That’s because each Ebola virus is encased in an envelope taken from the outer surface, or membrane, of a host cell.
      So what about cells in water that are infected with Ebola? Could you get the virus from infected cells in contaminated water?
      Infected cells don’t live long inside a liquid that doesn’t have the same salt concentration as in our bodily fluids.”

    I hope nobody objects to a little profanity, if they do then my apologies…

    WE ARE F****D !!!

    Not connected to this article, but still Ebola…

    The infection in Liberia is reported to be slowing…

    “Ebola crisis: Infections ‘slowing in Liberia'”
    http://www.bbc.co.uk/news/world-africa-29822303

    Personally, I suspect this may be more a case of the people in Liberia becoming more wary of reporting cases of suspected Ebola to the authorities.

    The count in Liberia has been somewhat hinky for a while now.
