“…They are known to cause either asymptomatic or mild symptoms of upper respiratory and intestinal infections, in some cases febrile exanthema with fever (Jackson and Muldoon 1973;Clarke and Tyler 2010;Dermody et al2013). ReoVs have been occasionally found in fecal specimens associated with childhood diarrhea (Giordano et al 2005). More recently novel ReoVs from nonhuman animals have been identified with some infecting humans and thus raising concerns about their zoonotic potential (Chua et al 2007;Zhang et al 2011;Kohl et al 2012;Dermody et al 2013;Yamanaka et al 2014;Kawagishi et al 2016).…”

The genus Orthoreovirus contains nonenveloped viruses with double-stranded gene segments encased in a double-layered icosahedral capsid shell. These features constitute major determinants of virion stability in the environment and virion resistance against physical and chemical agents. Reovirus (ReoV) is the general term most commonly used for all virus strains that infect humans and nonhuman animals. Several studies have demonstrated the frequent occurrence of ReoV in wastewaters and natural waters, including surface and ground waters from different geographical areas. Most of these studies have reported higher concentrations of ReoV than any other enteric virus analyzed. They are more commonly isolated in chlorine-disinfected wastewaters than other enteric viruses, and appear to survive longer in water. The ability of ReoV to form large aggregates, even with different types of enteric viruses (e.g., poliovirus) and their ability to undergo mechanisms of gene segment reassortment among different serotypes may also explain their greater stability. Different approaches have been applied for concentration of ReoV from water; however, the recovery efficiency of the filtration methods has not been fully evaluated. Recently, molecular methods for identification of ReoV strains and quantification of virus genome have been developed. Studies have shown that the overall detection sensitivity of ReoV RNA is enhanced through initial replication of infectious virions in cell culture. More studies are needed to specifically address unresolved issues about the fate and distribution of ReoV in the environment since this virus is not commonly included in virological investigations.
