"Functional cure" means that the virus in the infected person is completely suppressed and the immune function of the body is normal. Even without treatment, it is difficult to detect the virus in children's blood by conventional methods. On March 3rd, 20 13, researchers from Johns Hopkins Children's Center, University of Mississippi Medical Center and University of Massachusetts Medical College reported that they had achieved a "functional cure" for an HIV-infected baby for the first time. This achievement will help pave the way for the complete eradication of HIV infection in children.
