The Virus Bulletin prevalence table is compiled monthly from virus reports received by Virus Bulletin; both directly, and from other companies who pass on their statistics.
Reports are included only if they are confirmed, and hence, in conjunction with the WildList, the prevalence table provides a useful indication of the relative prevalence of various virus found in the wild at the time.
