  abstract = {{T}he available knowledge on the epidemiology of {R}ice yellow mottle virus ({RYMV}) is reassessed in the light of major advances in field and molecular studies of the disease it causes in rice. {P}reviously undescribed means of transmission by mammals and through leaf contact have been discovered recently. {S}everal agricultural practices, including the use of seedbed nurseries, have also contributed to a massive build-up of {RYMV} inoculum. {P}hytosanitation is now known to be critical to reduce disease incidence in rice. {A} new model of the ecology of {RYMV} in which man plays a central role has emerged. {F}urthermore, estimates of the evolutionary rate of change of {RYMV} provided a time-frame for its epidemiology, the first attempt for a plant virus. {E}arlier interpretations of the patterns of virus diversity which assumed a long-term evolution, and assigned a major role to adaptive events had to be discarded. {I}n contrast, a wave-like model of dispersal of {RYMV}, which postulates its initial diversification in {E}ast {A}frica, followed by westward spread across the continent, was developed, refined and dated. {T}he most salient - and largely unexpected - finding is that {RYMV} emerged recently and subsequently spread rapidly throughout {A}frica in the last two centuries, {D}iversification and {S}pread of {RYMV} has been concomitant with an extension of rice cultivation in {A}frica since the 19th century. {T}his major agro-ecological change increased the encounters between primary hosts of {RYMV} and {C}ultivated rice. {I}t also modified the landscape ecology in ways that facilitated virus spread.},
