| | The Relationship Between HIV and AIDS |
 | | However, AIDS represents only the end stage of a continuous, progressive pathogenic process, beginning with primary infection with HIV, continuing with a chronic phase that is usually asymptomatic, leading to progressively severe symptoms and, ultimately, profound immunodeficiency and opportunistic infections and neoplasms (Fauci, 1993a). |
 | | In clinical practice, symptomatology and measurements of immune function, notably levels of CD4+ T lymphocytes, are used to guide the treatment of HIV-infected persons rather than an all-or-nothing paradigm of AIDS/non-AIDS (CDC, 1992a; Sande et al., 1993; Volberding and Graham, 1994). |
 | | In a study of 481 infants in Haiti, the survival rate at 18 months was 41 percent for HIV-infected infants, 84 percent among uninfected infants born to seropositive women, and 95 percent among infants born to seronegative women (Boulos et al., 1994). |
