Todas las sesiones se transmitirán en vivo de 08.00 am. a 13.30 hs. pm. ARG (11.00 am. a 16.30 hs. pm. GMT), sin sesiones paralelas. Todos los contenidos autorizados de la Reunión Científica GFRA serán registrados y podrán ser visualizados por los asistentes registrados en cualquier momento en la Plataforma virtual.

Las sesiones de pósteres en vivo serán por las tardes entre las 13.40 pm. a las 15.00 hs. pm. Hora ARG (de 16.40 pm. a 18.00 hs. pm. GMT) y los asistentes registrados podrán acceder a ellas en cualquier momento en la Plataforma virtual.

El Programa Científico incluye cinco sesiones principales: Epidemiología, Vacunas e Intervenciones Terapéuticas, Patogenia e Inmunología, Virología y Diagnóstico.

La Reunión GFRA 2021 tendrá una duración de tres días y cada día incluirá dos conferencias plenarias (~ 20 minutos) y una charla de oradores invitados (~ 15 minutos) antes de las presentaciones orales de los resúmenes seleccionados (~ 10 minutos). Las charlas incluirán contribuciones generales o trabajos publicados recientemente sobre temas de fiebre aftosa. La representación geográfica y el equilibrio de género se han considerado en la elección final de los oradores seleccionados.

La sesión de apertura se centrará en la situación de la fiebre aftosa en América Latina para darle a la reunión un sello regional y abordar la situación de la fiebre aftosa en todo el mundo, y cómo la experiencia en el manejo de los brotes de fiebre aftosa se compara con la de la pandemia actual de COVID-19.
