This section asks you to estimate how many people within a particular group of employees are likely to be infected with HIV. As we explained above, the group may be the entire workforce of a particular country, or sub-sections such as 'managers' or 'unskilled workers'.

You may have some indication of prevalence in your workforce from company records or local research. If not, the pull-down list gives the averages within particular countries. These averages are based on UNAIDS estimates from 1999 and apply to the general population aged 15 - 49. It is important to note that prevalence within particular workforces may differ from that found within the population as a whole. In many cases, for example, high-income, urban males have higher-than-average rates of infection with HIV. Thus, these estimates should be seen as a guide only.

You are then asked for the average annual salary of the workers in the chosen group.
