Medically, it's unsanitary for any human being who could potentially be a carrier of some foreign born bacteria/virus to place their lips on wound/laceration.
Anyone could potentially be a carrier of anything. A doctor walking through a ward might have a cold. Hospital-acquired infections are a problem but the solution isn't to ban hospitals. If you look at the response to these cases that I posted, you will see that the The question of what is taboo is cultural. In some, touching feet might be taboo (I know a doctor who refuses to do this, and requires her patients to wear socks) but in others, it isn't. A man's touching a woman's breast is an issue unless he is a specialist. Some would say it is necessary, others not. Some would say that a spiritual healing is necessary and others not. Cross cultural judgments based on local taboos are dangerous.
Something I read about the recent cases,
"Over the past two years,
according to The Forward, E. Oscar Alleyne, director of public health planning in Rockland County, New York, conducted DNA tests – the only conclusive way of identifying the source of a herpes infection – on three mohelim who performed MBP on babies that later tested positive for herpes.
The result of one investigation was inconclusive. The results of the other two showed that the two mohelim were clearly not the source of the disease."
'Oral suction' provides anti-circumcision activists with dubious ammunition
Again, and as I have said in this thread, i am not trying to defend the practice. I am just concerned about the way it is being presented.
