You may be interested in a training methodology which uses participatory activities to ‘translate’ medical terminology for LMIC health programmes and low literacy contexts.  For example, to explain immune function, viral load, HIV mutation and why treatment adherence is vital, patients or community members wearing “White Blood Cell”, “HIV”, “Infection”, and “ARV” masks are involved in role playing the interactions between these different characters.  www.boht.org includes a short video with clips of this and related activities being used in health education programmes throughout Africa.
