You can’t. Sure worked for the Ebola patients that Dr Duncan infected didn’t it?
That's the case with all of the questions you are asked prior to donating. Have you been to certain countries? Have you had sex with men? Have you had sex with prostitutes? Etc.
It's all based on trusting the word of the donor.
Hopefully, they will test donated blood to confirm that it is disease-free. But they probably won't, due to the costs and the time involved with testing.
Answer: We don’t, and they will lie. Good God, what is wrong with these fools?
