The use of narcotics can increase your risk of HIV if their abuse affects your judgment about sexual safety. The safe, prescribed use of narcotics doesn't increase the risk of HIV.
No.
Yes; having a STD absolutely does increase your chances of contracting HIV.
Yes it does; you are more apt to catch HIV if infected with a STI.Since the STDs reduce you immune system response, your immune system is less likely to protect you from the HIV infection.Yes having STDs such as herpes and chlamydia does increase the risk of getting and spreading HIV.
Yes it does.
STDs do not reduce the risk of getting HIV. In fact, STDs increase the risk of getting HIV. Any STD elicits an immune response. Its almost like ringing the dinner bell for HIV. Most infections pull CD4 immune cells (cells that HIV infects) to the site of infection (usually). This increases the risk of infection.
It's easier to get HIV while you have chlamydia because of changes in the reproductive tract due to infection. Also, if you haven't changed the risk factors that made getting chlamydia possible, you are also at risk for HIV. I don't know of any research or mechanism by which past chlamydia can increase the risk of future HIV.
Yes, there are reports that say that HIV positive mothers who are breastfeeding will reduce the risk of the baby contracting HIV.
Being promiscuous (having a lot of sexual partners) does not create HIV - you have to be infected by one of your partners (or by some other means on transmission). The fact that you are promiscuous (have a lot of sexual partners) does not significantly increase your risk of contracting HIV. The risk would arise if you were not having safer sex with them.
only if patient has HIV to begin with.
It's a very high risk.
High risk behaviors that spread HIV are unprotected sex and sharing needles.
HIV risk is not linked to blood groups, it is linked to life style.
