[Estimate of the total number of HIV-infected subjects in the Federal Republic of Germany based on data from the AIDS Center].

On the basis of an analysis of the data from the mandatory reporting of detected HIV infections and the reports to the central AIDS case registry an attempt is made to determine the total number of HIV infected individuals in the FRG. Results of surveys of testing behaviour in different risk groups were included in the calculations. For the calculation different estimates were used as to the total number of detected HIV infections, distribution of infections and percentage of detected infections in different risk groups. Depending on the estimates chosen a "best case" calculation yields 29,515 and the "worst case" calculation 81,949 HIV infected persons at the end of 1990. A synoptic analysis by the AIDS Center of the Federal Health Office resulted in an estimate of 50,000 to 60,000 HIV infected individuals in the FRG which is well between the "best" and "worst case" estimates.
