Has he never heard of a virus mutating?
Nothing I have read leads me to believe that change in the way it is transmitted is even remotely possible. THAT said, the article is incorrect and confusing. “Direct contact” could be a problematic phrase. When I read the warnings from experts, in my mind I see “indirect contact.” Touching an object a sick person transmitted fluids to seems “indirect,” not “direct.”
It would seem the virus can pass through skin.
The virus also lives for a few hours on dry objects, like doorknobs, or for a few days in moisture.
If Ebola requires direct contact to spread why did the head of the CDC say, earlier this week, that if you had indirect contact, stayed within three feet, with an Ebola infected person you became a medical person of interest who had to monitored for 21 days. BTW - 21 days of monitoring is the time that the CDC uses for people who had direct contact with an Ebola infected person.
IMHO this kind of internal contraction, a war between technically correct and practical application, is creating a significant part of the “Ebola Scare”.
