Respiratory distress at 3-6 weeks of age, often with associated conjunctivitis.
Infection occurs as the fetus passes through the cervix and vagina at birth.
As well as causing respiratory distress, chlamydia trachomatis also causes conjunctivitis. Chlamydia trachomatis is neither a bacteria or a virus, but is rather an obligate intracellular parasite. Diffuse perihilar interstitial infiltrates are seen. Effusions may occur, and consolidation is rare. See References chapter at the end of the book.
