The city Health Department has reported a new case of neonatal herpes caused by a controversial ritual Jewish circumcision.
The ancient practice — known as metzitzah b’peh — requires a mohel, the person performing the circumcision, to suck blood from the incision on an infant’s penis.
It has long been linked to neonatal herpes and has consistently raised red flags in the medical community.
The practice continues without restriction in the city after Mayor de Blasio made a pledge to the Hasidic community during his 2013 campaign to lift a requirement of written parental consent.
Health officials sent out an alert to doctors Wednesday about the latest case and urged them to be vigilant.
The infant in the new case was hospitalized for 14 days and was reported to be recovering.
According to the Health Department, 24 cases of herpes have been linked to circumcision since 2000. Two of the infants died and two others suffered brain damage.
