How is HIV spread??? I am just have difficulties in understanding this statement. Surveys have found that more than one in five gay men in urban cities are HIV positive, and the virus is more prevalent among MSM of color and certain communities. If you are HIV positive and pregnant, you can take medications and other precautions to significantly reduce the risk of infecting your infant, including not breast-feeding. Everyone who has unprotected sex with an infected person is at risk of contracting HIV, but people who already have another sexually transmitted disease STD are even more at risk. PEP should be used only in emergency situations and must be started within 72 hours after a possible exposure to HIV, but the sooner the better. Have less risky sex. Sharing needles also can pass hepatitis and other serious infections to another person. How can I avoid acquiring HIV from a contaminated syringe? My question is we have anal sex and vaginal intercourse.
