IF I REMEMBER RIGHT RESTON IS THE STRAIN THAT ONLY SEEMS TO INFECT MONKEY'S
AND NOT HUMANS. THIS WOULD PROBABLY A RECEPTOR PROBLEM. MOST VIRUSES USE USE
RECEPTORS ON CELLS FOR INFECTION. THIS STRAIN MAY USE A RECEPTOR THAT IS
ONLY FOUND ON MONKEY CELLS AND NOT HUMAN CELLS.

AGAIN FROM MEMORY ITS TIMING. THE DISEASE ONSET IS FAST AND OVERWLEMING TO
THE IMMUNE SYSTEM THE IMMUNE RESPONCE JUST CAN'T MOUNT A STRONG ENOUGH
RESPONCE FAST ENOUGH

>> Q: What are the chances of Ebola reaching the USA?
>A: That isn't a great problem. You have to fly to Africa, infect with Ebola

>> Q: Is it true that some people in Africa have antibodies to help fight
off

>A: I heard of that. But I don't know if it is really true. But why not? It

ANTIBODIES FROM SURVIVORS OF THE INFECTION ARE CREATED. DON'T KNOW AS TO
THEIR EFFECTIVENESS AGAINST RE-INFECTION

>A: Yes, but I wrote that already at the first question.

>> Q: What is most likely the host or cause of Ebola?

RESCENT RESEARCH POINT AT A BATS, FRUIT BATS I BELIEVE TO BE THE NATURAL
