A 28-year-old otherwise healthy woman was near death from an unidentifiable infection. The costs of her care reached hundreds of thousands of dollars in a matter of days. A quarter of that went to failed diagnostic tests, including a lung biopsy that itself had a mortality rate of 10-15 percent. In 24 hours, a new viral chip made the diagnosis and saved her life. Joseph DeRisi will discuss his latest work on diagnosis of infections of unknown origin, and a project on malaria.
