Abstract
Cycloviruses, small ssDNA viruses belonging to the Circoviridae family, have been suggested as possible causes of enteric, respiratory and neurological disorders in human patients. One of these species, cyclovirus-Vietnam (CyCV-VN), initially isolated from cerebrospinal fluid samples of patients with unexplained neurological disorders, has since been reported in serum samples from chronically patients infected with HBV, HCV or HIV, in Italy. On the other hand, CyCV-VN was not detected in serum samples from healthy individuals. Here, we report on a high prevalence of 43.4% (40/92) of CyCV-VN in plasma samples from asymptomatic blood donors from Madagascar. Interestingly, this virus was not detected by metagenomics and PCR in six other African countries, suggesting regional differences in CyCV-VN prevalence across Africa. Phylogenetic analysis based on the complete genomes showed that CyCV-VN sequences isolated from blood were most closely related to sequences previously reported from human stool in Madagascar. Further investigations using larger cohorts are required to determine the global epidemiology, the natural history and the pathological significance, if any, of CyCV-VN infection in humans.
