Again the individual would still test positive and all blood is tested for HIV. The reason for a ban is to avoid people donating in a window period PRIOR to it being at a detectable level. They still are HIV positive during any dormancy period. AIDS isn't relevant to the current topic because someone who has developed AIDS will not be donating at all.I modified my initial post to say that AIDS/HIV can lie dormant for years, sometimes over a decade. As can "mad cow disease."
Of course, you can detect it with testing sooner. But the point is that a person can be infected and not know it for over a decade. Not everyone at risk gets tested before any symptoms.
And not everyone is honest with their partners about risky behavior either. But that's a whole other story.
From the Mayo Clinic website:
HIV/AIDS: Symptoms - MayoClinic.com
The Different Stages of HIV Infection
how long can hiv be dormant - Forum on Mental Health and HIV
HIV - Wikipedia, the free encyclopedia
This source says a person can be symptom free for up to twenty years (two decades).
HIV/AIDS
As noted, the UK considered this and found a 2% increase in risk from a base risk of something like 1 in 2 million.
Modern tests can detect it within 12 days, although the ELISA tests are still more commonly used and have the 3-6 month window. A 12 month window more than solves the problem. And none of this acknowledges that heterosexuals with 'risky' behavior are still at a high level of risk for HIV. Not as high as MSM but high.
