1 Barrier methods under development are addressing some of these limitations. They are not currently available, but are under development and being tested for efficacy as an alternative to current methods. Microbicides may come in the form of gels, creams, foams or films that can be inserted into the vagina or rectum. 12 Studies show that there is large potential demand for microbicides from women in the US and internationally. 13 People are also willing to participate in efficacy trials, as studies in women and MSM have shown.
Male condoms are currently the best comprehensive prevention method.
Education and prevention campaigns must be continued to optimize condom usage while also searching for alternatives. HIV prevention efforts may be more effective among certain populations if condom use and HIV are addressed together with STD and unintended pregnancy prevention. Some STD and family planning clinics are encouraging condom use for both STDs and HIV prevention with great success. 16 New physical barrier methods currently being researched include the disposable diaphragm, alternative types of cervical shields, caps and sponges and alternative types of condoms, both male and female. New materials are also under development, including various plastics and silicone rubber.
