In 2006, the CDC recommended expanding HIV testing in the U.S., but the recommendation was not accompanied by any increases in federal funding for testing or subsequent care. Now, researchers have used a computer simulation model to explore how expanded testing and treatment would affect U.S. government budgets over the next 5 years.
The researchers compared the current testing rate (an average of 1 test per adult every 10 years) with an expanded rate of 1 test per adult every 5 years. Their model used 2008 estimates for prevalence (1.1 million cases) and incidence (56,000 new infections per year) and assumed that 97% of newly diagnosed HIV-infected patients received their test results and that 80% were then linked to care. Drug costs were e…
