I have been wondering about what I heard about the dreaded Ebola Virus. My question is

1. I heard the virus can't survive heat, so how come they said ebola virus can be infected when you eat bush meat, are they saying people eat uncooked bush meat? If bush meat is cooked it has gone through maximum heat the virus can't take.

2. I heard on the news it started wey back in 1976, how come the sudden spread after 38 years and less than 3000 reported cases? If the virus kills so fast which is true, planet earth would have been wiped out by now since there is no cure.

3. How come we haven't heard news about Ebola Virus ever since until January this year?
