Researchers Unable To Document Existence Of Transient HIV Infection In Infants
...ountry. In all 43cases, blood tests had originally shown evidence of HIV infection on one or moreoccasions, but later tests did not find evidence of HIV-1. The researchers re-analyzed the infant specimens that had testedpositive for HIV-1 and the mothers' specimens. They performed tests to study th......
