As many as half of all infants born to mothers with chlamydia will be born with the disease.
Chlamydia can affect infants by causing spontaneous abortion; premature birth; conjunctivitis, which may lead to blindness; and pneumonia.

To treat chlamydia, your pediatrician will prescribe antibiotics such as oral doxycycline or azithromycin.
A child with chlamydial pneumonia or conjunctivitis should be treated with oral medications like erythromycin.
Topical treatment of the eye infection, such as with eyedrops, is ineffective and unnecessary.
