Researchers have described the first documented case of a child being cured of HIV. The case involves a two-year-old child in Mississippi diagnosed with HIV at birth and immediately put on antiretroviral therapy. At 18 months, the child ceased taking antiretrovirals and was lost to follow-up. When brought back into care at 23 months, despite being off treated for five months, the child was found to have an undetectable viral load. A battery of subsequent highly sensitive tests confirmed the absence of HIV.
