I know this may be considered racist.....but, is it possible that Caucasians are more likely to contract the disease than Africans?
The disease has been in Africa for decades (and probably longer undiscovered)...and around 30% live through it...passing their genetics down to the next generation. This may build a degree of tolerance that Caucasians don’t have.
For the most part, the only Caucasians who ever come in contact with the virus are wearing protective gear (and some still get infected), so we really wouldn’t know about the ability to resist the virus.
The virus been in Africa several thousand years from what I heard.
Tough to say about that. Reasonable speculation, ancestral exposure to Malaria has provided at least some immunity to some people of African descent.
But, then there’s Dengue, another hemorrhagic virus. Several strains, four or five, exposure to one provides immunity to the one, but weakens you and makes you more likely to succumb to a different strain.
