In addition to misconceptions about HIV transmission, many adults also hold misconceptions about HIV prevention and treatment. In 2006, more than half the public did not know that having another sexually transmitted disease can increase a person’s risk of getting HIV (56%), and that a pregnant woman with HIV can take drugs to reduce the risk of her baby being infected (55%). Smaller shares did not know that there is presently no cure for HIV (14%) and that there are drugs that can lengthen the lives of people with HIV (13%).
