生殖期胞疹与怀孕
大意：在美国大约5000万人感染有生殖期胞疹（基本属实，大约20%或更高）。事实上，由母亲感染给新生儿的几率非常之小。
在美国，患病母亲感染给婴儿几率为1/2000，英国1/65000，日本，1/15000。（中国人体质接近日本，估计也会在1/15000左右）
最值得注意的是要防止母亲在第一次发作时生育。文中指出在母亲第一次发作时生育，新生儿被感染的几率在30-50%。这是因为第一次发作体内会有最多的病毒和最少的抗体。
The greatest risk to the infant is in those pregnancies in which the mother develops her first genital herpes infection ever while pregnant2. In those pregnancies the risk to the baby of catching herpes simplex while in the womb is as high as 30 to 50% if the mother has the first outbreak of genital herpes during the final three months of pregnancy. This presents a very high risk to the baby, and it is a risk that can be avoided with careful attention.
