The surveillance of HIV-1 infection and AIDS in England and Wales. PHLS AIDS Centre.

Comprehensive surveillance is necessary for effective and efficient primary prevention as well as appropriate resource allocation for patient care. The surveillance of HIV-1 infections and AIDS in England and Wales is based upon voluntary confidential reporting by clinicians of AIDS cases and deaths in HIV-1 infected persons without AIDS, monitoring of named HIV-1 tests through laboratory reports and a special collaborative laboratory study. In addition an unlinked anonymous HIV-1 prevalence monitoring programme has been developed recently to provide a more accurate picture of the evolving epidemic.
