Dont forget that in several areas where it has burned through already , they are seeing a resurgence of Ebola.
This might be due to fomites , or to the rainey season.
SInce the virus can remain vital for up to 5 days on either hard surfaces , or in water , I am sure that the West African 'rainey season' is assisting to resurgenece.
QUESTION : Has anyone seen thermal effects on the viability/vitality of the virus ?
Does the virus have the ability to go into 'suspended animation' in freezing temperatures , and then re-annimate ?
I ask this because some virus samples had been nitrogen frozen by the CDC .
I have not seen anything which maintains that the virus does not survive in dried out secretions, at least for a few hours, depending on UV exposure and temperature. . It would be easier to pick up a liquid or wet patch with the virus in it on fabrics or skin than the dried crust, but with an ID50 of one to ten virons, moist tissue or material (food, for instance, dropped on a counter or table and picked up and eaten) should be able to transfer enough virus to infect if introduced to any opening in the skin or mucous membrane or the eyes.
Whether this can survive long enough and be sufficiently carried in dust to cause infection is anyone's guess. I simply do not know.
Yes: http://jid.oxfordjournals.org/content/196/Supplement_2/S142.long
Virus was detected by culture .... which to me means the virus survived the freezing and was able to be cultured.
IIRC, it is known to survive at -70 degrees.
Cold kills cells by slowing chemical processes below viable levels, and by ice rupturing cell walls.
A virus outside a cell has no active metabolism, and is not destroyed by ice formation.
