Subcutaneous (SC)
           Beneath the skin, or administration of a substance beneath the skin.


        Subcutaneous Adipose Tissue (SAT)
           A type of adipose (fat) tissue found directly under the skin. Both loss
           (lipoatrophy) and gain (lipohypertrophy) of this fat tissue can occur
           as a side effect of HIV infection and some of the drugs used to treat
           HIV infection, especially PIs and NRTIs.

        Substance Abuse and Mental Health Services
        Administration (SAMHSA)
           The lead agency within the U.S. Department of Health and Human
           Services (HHS) for improving the quality and availability of substance
           abuse prevention, addiction treatment, and mental health services

        Subtype
           HIV is classified into two types, HIV-1 and HIV-2. Within HIV-1 are
           groups of similar viral strains. These are the major (M) subtype and
           non-M (new [N] and outlier [O]) subtypes. The majority of HIV-1
           infections are by M-subtype viral strains. Subtype M HIV-1 is further
           broken down into nine genetically distinct strains known as clades.

        Subunit HIV Vaccine
           Also known as a component vaccine. Subunit vaccines contain     S
           only part of the HIV virus (such as individual proteins or peptides)
           produced in the laboratory by genetic engineering techniques.

        Superinfection
           A new infection acquired on top of an existing infection. For
           example, a person infected with one strain of HIV-1 can, if exposed
           to a different strain, become infected with the new strain in addition
           to the existing strain. Superinfection can complicate HIV treatment
