The symposium will be an excellent opportunity to show and discuss the latest results related to virus epidemiology, including aspects of detection and etiology, virus dissemination, virus evolution, through experimental or modelling approaches. The local organising committee wishes to encourage exchanges and interdisciplinarity during this 13th edition entitled "Building bridges between disciplines for sustainable management of plant virus diseases". The focus will be on the sustainable management of means of combating viral epidemics, which is a key issue in virology at both the fundamental and agronomic levels.
