How soon after birth can HSV conjunctivitis manifest?

Herpes Simplex Virus (HSV) conjunctivitis can manifest in newborns typically within the first two weeks after birth. The timeline is significant because HSV can be acquired during delivery if the mother has an active genital herpes infection. When the virus comes in contact with the baby’s eyes, usually between one and two weeks postpartum, it can lead to conjunctivitis, presenting with redness, discharge, and sometimes signs of keratitis or corneal involvement.

While some conditions can arise sooner than this timeframe or later, HSV conjunctivitis is most notably observed within this two-week window. Early detection and subsequent management are critical to prevent complications, especially since the virus can progress rapidly in newborns. Understanding this timeline provides crucial insight into monitoring and managing newborns at risk for HSV infection.
