PREVENTION Because there is no effective vaccine and no cure for HIV, the only way to protect oneself is prevention. People should either abstain from having sex or use latex condoms, during oral, anal, or vaginal sex. Only condoms made of latex should be used, and whenever necessary only water-based lubricants should be used. People who are allergic to latex can use polyurethane condoms. Although some laboratory evidence shows that spermicides can kill HIV, there is no conclusive evidence if it can preventtransmission. The risk of HIV transmission from a pregnant woman to her baby is significantly reduced if she takes AZT during pregnancy, labour and delivery, and her baby takes it for the first six weeks of life. Nevirapine is also found to be useful. But, one should seek expert medical assistance in such situations. Click here for Services.
