Both the chlamydia bacteria and HIV can be co- transmitted, or only one, or neither.
In general the rate of transmission of chlamydia from a woman to a man is about 32% (and from a man to a woman about 40%) from a single unprotected sexual exposure.
The rate of HIV transmission is much less- in general 5 to 10 per 10 000 with penile/ vaginal intercourse.
I hope that helps.
Always ask if you need clarification/more information.
POSITIVE feedback & a BONUS are warmly appreciated. Please note that answers are for information only, do not take the place of an IN PERSON assessment by your doctor,and does not establish a patient-physician relationship.
If chlamydia is transferred, there may be a higher rate of HIV transmission- HIV viral levels tend to be higher in the genital secretions with co-infections.
But again it is not a guarantee- HIV may or may not be transmitted as well. There is no guarantee either way.
