SOFTWARE IN THE FIELD OF HIV/AIDS SURVEILLANCE
EPP: Epidemic Projection Package
EPP is used to estimate and project adult HIV prevalence in countries with heterosexual epidemics. The input to EPP is surveillance data from various sites and years showing HIV prevalence among pregnant women. EPP is used to fit a simple epidemic model to data from urban and rural sites. The prevalence projection produced by EPP can be transferred to Spectrum to calculate the number of people infected, AIDS cases, AIDS deaths,etc. EPP was developed by the UNAIDS Reference Group on estimates, models and projections and programmed at the East West Center.

SPECTRUM
The models comprising SPECTRUM are used to project the need for reproductive health services and the consequences of not addressing reproductive health needs. One specific model is called AIM: AIDS Impact Model. AIM projects the consequences of the HIV/AIDS epidemic, including the number of people living with HIV/AIDS, new infections, and AIDS deaths by age and sex as well as new cases of tuberculosis and AIDS orphans. AIM is used by UNAIDS to make the national and regional estimates it releases every two years.
