Infectious disease experts widely agree that the oral contact, known in Hebrew as metzitzah b’peh, creates a risk of transmission of herpes that can be deadly to infants, because of their underdeveloped immune systems. Between 2004 and 2011, the city learned of 11 herpes infections it said were most likely caused by the practice. Two of those babies died; at least two others suffered brain damage.
