*4.2.1.1 Chlamydia neonatorum*

Chlamydia can be presented in different age groups in pediatrics. In the neonate, it is also known as Chlamydia neonatorum. Infection in neonates results from perinatal exposure to the mother's infected cervix. Initial infection involves the mucous membranes of the eye, oropharynx, urogenital tract, and rectum, although infection might be asymptomatic in these locations. The most common manifestation in neonates is conjunctivitis that develops 5–12 days after birth. Nowadays, this infection is much less frequent due to widespread prenatal screening and treatment of pregnant women.
