*Data are presented according to three key transmission groups that are available from the EuroHIV report for the year 2006. As the number of cases attributable to mother-to-child transmission is small, these data are not presented. The proportion of unknown cases of transmission is not available from the EuroHIV report.
In Estonia, data on the mode of transmission are not available since 2002. Turkmenistan reported only two cases of HIV since 1989.
