If left untreated can chlamydia turn into HIV or aids?

Absolutely not. Chlamydia is a sexually transmitted disease caused by the bacterium Chlamydia trachomatis. Although HIV is also a sexually transmitted disease, it is a VIRUS, not a bacteria, and not in any way remotely related to the chlamydia bacteria. Bacteria do not change into viruses at any time. AIDS is the progressive end-stage form of HIV so that would not be derived from chlamydia either. .
