First, the average transmission risk for genital HSV-2, when onepartner is known to be infected, is under 1 in 1,000 for each epsiodeof unprotected sex. Your risk probably is lower than that, since theunprotected exposure, after condom breakage, was brief. (In monogamouscouples in which one person has HSV-2 and the other does not, who takeno precautions against transmission, on average the infection istransmitted in only 5% per year, i.e. 1 in 20 couples -- and half ofall partners never catch it.
首先，一方明确感染HSV－2的患者，在每次无保护性交的情况下，传染给对方的机会差不多是1/1000。而你的风险可能比这个更低，因为无保护的接触主要是安全套破裂以后。在一夫一妻的情况下，一方有感染HSV-2，而另外一方没感染，在没有注意保护的情况下，平均一年只有5％的可能被传染，也就是20对夫妻只有1对会出现被感染的状况。
这个是我翻译的，就是“美国疱疹专家Hunter Handsfield关于无症状疱疹的观点 ”中的说法。感觉这个感染概率好像太低了吧！远远低于国内论文发表的情况，和网上查到的也出入非常大。这个说法正确么，有点怀疑！
