Since 2004, the ENVA has worked in partnership with the CIRAD to develop a distance learning course in basic epidemiology for animal diseases. The current method is based largely on a handbook on veterinary epidemiology which was adapted to suit computer assisted learning sessions. During several training workshops in AI epidemio-surveillance organised by the FAO for Southeast, East and South Asia, Africa, East Europe and Middle East, RANEMA was used as a supplement to increase the impact of the training. This was a new interactive and recreational way to acquire bases in epidemiology. Although RANEMA is a stand-alone tool, the use of the complete set of training material has been maximised by the organisation of a specific training of trainers. Such training was organised by the OIE Regional Representative for Asia and the Pacific in July 2006 for nine countries of Southeast Asia. Ranema is also used at Chulalongkorn University to train veterinary students in epidemiology. New modules are under development e.g. RANEMA-Flu for applying specific recommendations on AI surveillance and control, basic statistics, risk analysis. Evaluation of the efficacy and impact of these trainings should be undertaken by means of surveys in involved countries and/or by a regional meeting.
