Have so few people in Dallas come down with it?
If it's not contagious, then why are so many people in West Africa dying from it?
That's what I'm wondering. Bad hygiene in countries that often don't have running water? Has the virus mutated and become less virulent?
From my reading, the original outbreaks of Ebola were in isolated villages in which the people were certainly poor and the conditions unhygienic. The isolation enabled quarantining and prevented the spread of the disease. What has made the current outbreaks so much deadlier is that some have occurred in more urban, dense areas.
The case of the American doctor who survived is quiet interesting. He was given plenty of rehydration solution. Severe dehydration must have a negative impact on an Ebola patient's immune system. I suspect the first nurse is doing better from proper palliative care as well, and that any future successful treatment protocol will be a combination of an antiviral combined with hydration and nutrition supplements.
