It is likely that the about 5-10% of Americans that are effectively immune to both black plague and HIV are also immune to Ebola. If one of their parents had the immunity factor, called CCR5 delta 32, they will get sick but recover; and if both parents have it, they won’t get sick.
It works by preventing cell adhesion by the virus. If a virus cannot stick to a cell and penetrate it to reproduce, then it and millions of its clones break out of the dead cell to spread, it dies.
The percentage of CCR5 delta 32 in different ethnic populations:
European Descent: 16%
African Americans: 2%
Ashkenazi Jew: 13%
Middle Eastern: 2-6%
Other peoples have little or no trace of the mutation.
Weren’t the two nurses in Dallas Vietnamese and black?
