Out of all those people they only have 25 who test positive. 25 people out of 12,000 - and not just 12,000 random people. 12,000 who has been exposed to a risk. That's only 0,002%!
Please also note that even if you did have sex with an HIV-positive girl - which is highly unlikely - the risk of transmission per vaginal exposure is 0.04% (= 1 in 2380).
Hope that gives you some comfort. Otherwise I'm sure the negative test will in a few days :)
