Question:
Ebola hemorrhagic fever belongs to a group of diseases called "emerging diseases" - diseases that were previously unidentified or had never been identified in human populations. Emerging diseases are often seen in third world countries. What factors may explain the emergence of new diseases in these countries? Describe the effects of filoviruses on the human body.
Answers:
The reasons that emerging diseases come from 3rd world countries is that those endemic to 1st world countries are already well researched and studied.
Many of the 3rd world countries are also located near the tropics giving them exposure to more exotic viruses.
Finally 3rd world countries are more likely to live in close proximity to their livestock. I won't go into details, but the flu virus cycle goes back and forth between chickens and humans.
