Soap and water inactivates HIV

Simple soap and water can knock out HIV, the virus that causes AIDS, in genital secretions. At least one previous study has shown that genital cleansing with soap and water after intercourse can prevent HIV infection, but the direct effect of a soap solution on HIV has not been investigated.Researchers from the University of California, San Francisco, tested the effects of a commercial bar soap (Ivory; Johnson & Johnson) and water on HIV and white blood cells in cervicovaginal lavage (CVL) fluid, in a mixture of CVL fluid and seminal fluid, or in a control medium.It was found that 2 or 6 minutes of exposure to soap and water decreased the infectivity of HIV by more than 1000-fold. When the virus was in a CVL-seminal fluid mixture, a stronger concentration of soap in water was required to reduce viral infectivity by 30-fold.The present study demonstrates that soap and water solutions are effective in inactivating HIV and HIV-infecting cells associated with barrier contraceptives or cells that are present in the vaginal canal. The main message of this research is that regular soap works to kill HIV. Its major use in this regard should be on other instruments, such as diaphragms, used to prevent HIV transmission. The researchers emphasized that soap and water should not be used as a douche to eliminate HIV from the vagina because this method has not been tested yet and soap can have adverse effects, including disrupting the lining of vagina that might actually make it more susceptible to infection, and altering the normal population of vaginal microbes that can protect against other infections.
