I was listening to the American military radio here in Korea and they invited soldiers to donate blood with some exceptions:
- if you’ve been shorter than 30 days in Korea
- if you got a tatoo in the last 6 months
- if you lived in Europe for more than 5 years
I really wonder what could have happened to someone who lived in Europe for more than 5 years which triggered this particular exception.
Ah yeah, that sounds about right, the 5 years incubation time and so on. Thanks!
Mad cow disease can take decades to have an effect. If you are some infected meat and have the wrong genetics you could wind up with a sponge for a brain 30 years later.
Prions are terrifying.
The five years is just due to cumulative risk. Someone decided to make that the cutoff.
