Rapid Risk Assessment: Cyclovirus in cerebrospinal fluid of patients with central nervous system infection
This assessment is related to the publication of the identification of a new cyclovirus species, tentatively named cyclovirus-Vietnam (CyCV-VN), in cerebrospinal fluid of patients with acute central nervous system infection. However, there are insufficient data to assess the risk for disease occurrence in humans or potential of human-to-human transmission. Further studies should be encouraged in Europe and elsewhere to investigate the possible pathogenicity, epidemiology, and transmission patterns of cycloviruses.
