To date, Anova has successfully carried out surveillance among female sex workers, men who have sex with other men and long-distance truck drivers. The current surveillance work is focused on persons who inject drugs. In future, a repeat of the population groups already surveyed will be done.
Whilst the past and current surveys have provided the baselined strategic information for Key Population, future surveillance work will help establish the trends and changes taking place within the epidemic as a result of various responses by various actors.
Anova’s surveillance work provides the evidence- base for Key Population programmes as well as policy formulation. It also helps in evaluating programmes coverage and in identify the gaps in programmes.
