Back to main issue

Seadornaviruses are lesser known emerging arboviral pathogens that have a wide geographic range as their members have been isolated or detected in Asia, Australia, Europe and North America. The genus has multiple members but Banna Virus (BAV) and Liao Ning virus (LNV) are of particular interest due to their pathogenic and virulent nature. At a glance, their disease causing capacity may pale in comparison to Dengue virus, Japanese Encephalitis virus, Zika virus and others along those lines but this capacity could increase significantly in the future as Seadornaviruses may have only recently began adapting to the vector/human transmission cycle. The type species of the genus, BAV causes a myriad of symptoms upon infection while LNV, another member shows wide tissue tropism in vitro and causes fatality upon reinfection in vivo. Additionally, it is possible that infection by Seadornaviruses may lead to long term sequelae. Cumulatively, the data suggests that BAV and LNV and possibly other members may be highly successful arboviral pathogens. Due to paucity of knowledge pertaining their clinical significance, research has stalled and consequently viruses of the genera are poorly characterized. The current review of Seadornaviruses aims to provide an update on the literature related to them in addition to raising awareness about them and their potential clinical significance. Similarly, discussions are performed throughout the manuscript to highlight future research directions.
