Any chemical that will kill microorganisms. Used synonymously with biocide and bactericide.
Gels or creams that can be inserted into the rectum or vagina, designed to reduce the risk of anal or vaginal transmission of viruses such as HIV. The aim is to kill or to inactivate the virus, creating a barrier to mucosal cells or preventing the infection from taking hold after it has entered the body. Largescale trials are underway but, at present, none is generally available, although safety and efficacy trials show encouraging early results.
An agent that kills microscopic organisms (bacteria, fungi, and viruses).
