* Not much is known about the prevalence of HIV among peacekeepers, because the UN rejects mandatory testing.
* In 2000, a US Intelligence Council Report estimated an HIV prevalence rate of between 10 and 20% among the armed forces of the Ivory Coast and Nigeria, and an even higher prevalence of 40–60% among the militaries of the war-affected countries of Angola and the Democratic Republic of the Congo.
* Surveys of Dutch personnel suggest that 45% routinely had unprotected sex with sex workers in Cambodia during a tour there.
I assumed it was more about the UN's fear of major dropoff in volunteer rates from countries/orgs that would be embarrassed about their infection rates. After all, the UN only exists because of the participation of all the member countries. They are right to fear hurting participation rates...
I'm not defending the spread of HIV, just noting that it's a nuanced challenge.
I was joking once that people in the hellholes of this world have enough problems even without our help.
Now I am not sure it is a joke.
