How does the cost-effectiveness of partner services compare with the cost-effectiveness of other case-finding strategies for HIV and STDs?
A. Published estimates have placed the cost of newly identifying one HIV-infected person through partner services between $3900 and $6600 (2006 US dollars). These estimates compare favorably to HIV counseling and testing programs as well as other interventions designed to identify HIV-infected persons. The estimated costs of identifying one HIV-infected person in health care settings have ranged from $5300 to $7900 (seropositivity rate of 2% to 0.6%), while the cost of identifying one HIV-infected person in jails is approximately $4800 (seropositivity rate of 0.6% to 1.3%). Given the high lifetime cost of HIV treatment, HIV prevention interventions such as partner services may be cost-effective if the cost of lifetime care (which a recent estimate placed at $385,200 when discounted at a rate of 3%) exceeds that of preventing one infection. Over the years, a small number of researchers have evaluated the cost-effectiveness of HIV partner services, and each study found that partner servi
