Blistering of the lips in newborns may be caused by contact with the herpes virus on the mother’s body, such as on the genital tract and nipple skin.
Due to the imperfection of the newborn’s immune system, the virus can lead to severe systemic reactions, even life-threatening; it can also be caused by having hand, foot and mouth disease, which has lesions visible on the hands, feet and perianal area in the course of the disease, in addition to blistering on the lips. This is why it is important to pay enough attention to blisters on the lips of newborns.
Of course, before that, it is important to first rule out external factors causing blisters on the lips, such as artificial feeding due to high water temperature.
