*Who doesn’t know that *chickenpox is the herpes virus?"

Comments below to an article (back in the news) about a chv"s sick baby:

 *The suggestion that Metzitzah B’peh is involved in the transmission of the herpes simplex virus has never been conclusively proven. In fact, the link is not as “scientifically” obvious as one may think. 
The only conclusive way of identifying the source of a herpes infection is DNA tests. We would need to test the DNA of the Mohel, and compare it with the DNA of the virus in the baby. Otherwise, the baby could have gotten it from someone else.

*I’ve been following this topic for years now
I think we can all agree that hundereds of baby boys are having Metzitzah B’Peh daily on 4 continents. (Mostly by Chassidim and other scrupulous ultra-orthodox Yidden.)
And… i don’t recall any such herpes case for well over a year. More like 2 years has passed since the last time a case like this was reported. (Usually reported by some modern orthodox, or non-religious, publication.)

Bottom line:
We will continue to follow our Mesorah (Ahl Pi Kabalah Metzitzeh B’Peh also has great spiritual benefits for the infant throught his life) as we have done for millenia.
Apparently the danger of herpes from M.B. is statistically much less than driving a car with a baby inside. Or allowing children to ride a bike, scooter or rollerblades.
(Of course, still, all sensible precautions should be implemented.)
