here where? i can assure you, in the united states, a positive result is reported along with name and used for tracking purposes

when they say confidential name based reporting... what they mean is they report your name, along with a lot of other information... to local county health departments.

it is a very controversial practice

Tracking HIV Trends By April 2008, all states had implemented a confidential name-based system for reporting HIV diagnoses to CDC. Tracking HIV trends is challenging and depends on several factors, such as how often people are tested, when during the course of their infection they are tested, whether and how test results are reported to health departments, and how case reports (with personal identifiers removed) are shared with CDC.

A major advance has been the development of the serologic testing algorithm for recent HIV seroconversion (STARHS). STARHS is a way of analyzing HIV-positive blood samples to determine whether an HIV infection is recent or has been ongoing. CDC currently funds 25 areas to conduct HIV incidence surveillance activities.

Today, monitoring trends in HIV infection requires the collection of information on diagnosed cases of HIV, including the ongoing collection of laboratory data for each person diagnosed, to monitor the stages of the disease (including progression to AIDS [stage 3 HIV infection]), linkage to and retention in HIV medical care, and HIV-related outcomes such as viral suppression, death, and survival. All 50 states, the District of Columbia, and 6 U.S. dependent areas use a uniform confidential name-based HIV infection reporting system for collecting data on HIV infection.
