Virus Reviews & Research is published by the Brazilian Society for Virology and accepts reviews, research papers and short communications dealing with all aspects of Virology and related fields. Authoritative and clinical reviews of the current state of knowledge are preferred, although important historical analyses might be accepted. Unevaluated compilations of the literature and annotated bibliographies do not fall within the scope of Virus Research. Authors of manuscripts of lectures delivered symposia and round tables are encouraged to evaluate the possibility of using such material for preparations of a review, as stated below.
