Human immunodeficiency virus, or HIV, can be transmitted by bodily fluids, including infected blood products, IV drug use or sex. As such, it is considered a sexually transmitted disease, or STD. Getting other STDs besides HIV does not increase your risk of getting HIV, but if you get an STD, then you likely have other factors or behaviors that increase the risk of contracting an STD, and therefore an increased risk of contracting HIV as well.
