Chlamydia trachomatis causes chlamydia infection, which can be treated with azithromycin or doxycycline. Neisseria gonorrhoeae causes gonorrhea, which would require treatment with ceftriaxone or cefoxitin. Since the patient tested positive only for chlamydia, options A and B that include gonorrhea antibiotics can be eliminated. Between azithromycin and doxycycline, azithromycin is preferred as a single dose treatment.D: Oral azithromycin
