Under Jewish law, mohalim must draw blood from the circumcision wound. Most mohalim do it by hand with a suction device,[9][10][11][12] but some follow the traditional practice of doing it by mouth. The Centers for Disease Control and Prevention issued a warning in 2012 about the health implications of the latter practice, citing eleven cases of neonatal herpes simplex virus (HSV) and two recorded fatalities.[13]
