30 female prostitutes and 16 persons from the hospital staff each tested 10 latex condoms by vaginal intercourse. Six dropped out. Condom rupture occurred at least once for 7/40 persons (95% confidence interval 7-33%). Total condom rupture rate was 5%. Although encouragement to condom use is prudent in an epidemiological scale, truly safe sex with an HIV-positive partner using condoms is a dangerous illusion.
30名女性性工作者和16名医院工作人员分别通过阴道性交测试了10个乳胶避孕套。6人退出。40人中至少有1次避孕套破裂的有7人（95%置信区间为7 - 33%）。避孕套总破裂率为5%。尽管从流行病学角度鼓励使用避孕套是谨慎之举，但与艾滋病毒阳性伴侣使用避孕套进行真正的安全性行为是一种危险的幻想。
