USPTO Abstract

An inexpensive, easily available and convenient method of inhibiting the transmission of the AIDS virus in humans as a result of sexual intercourse is provided. The invention relies upon a dual mode of action of antiviral compositions comprising biguanides such as chlorhexidine, alone or in combination with silver salts, such as silver sulfadiazine, or sodium deoxycholate. These compositions are effective to reduce the infectivity of the AIDS virus and also kill the causative organisms of many other sexually transmitted diseases (STD). The composition of the invention is therefore useful to reduce the immediate risk of AIDS transmission. It also reduces future risk of AIDS transmission by eliminating STD causing organisms which increase the risk of AIDS.
