I can't interpret the above formatting fully, but I would be of the view that chlamydia has been detected. I am pretty sure that is what the 'Current' infers after 'chlamydia contact'.
Azithromycin is also the standard prescribed antibiotic to treat chlamydia.
Metronidazole is prescribed for vaginosis from a range of other bacterial infections (some are naturally occurring in all vaginas and get out of control, others transmitted sexually).
Hence you need to assume your partner has chlamydia which is now being treated. If you have had unprotected sex with your partner, then it must be assumed you have it too and require treatment. You shouldn't have unprotected sex until you have negative proof of cure tests two weeks after treatment.
Note it is possible your partner has had chlamydia for up to a couple of years but naturally after any previous negative test.
