Test protocols have been developed to test water treatment devices/systems for use for treating drinking water that are used at the individual and home level to ensure the removal of waterborne viruses. Current test procedures call for the use of poliovirus type 1 and/or rotavirus SA11. Recently we suggested that selected coliphages could be used as surrogates for poliovirus for testing of point-of-use (POU) water treatment devices, however, rotavirus was not used in those studies. The purpose of this review was to compare studies of POU devices which were tested with poliovirus type 1, simian rotavirus SA11 and coliphage MS2 to determine if the behavior of rotavirus SA11 was significantly different. In addition, an attempt was made to compare the relative resistance of these viruses by various disinfectants used to treat drinking water. In all cases SA11 was removed to an equal or greater degree than poliovirus. SA11 was found to be less resistant to halogens, although one study found it to be more resistance to chloramines than poliovirus and MS2. Based on this review, use of coliphages for testing POU devices appear justified. Additionally, data on chloramines for these viruses would be useful to determine if rotavirus is more resistant than poliovirus and MS2.

Rotavirus (RV) accounts for 19.11% of global diarrheal deaths. Though GAVI assisted vaccine introduction has curtailed RV induced mortality, factors like RV strain diversity, differential infantile gut microbiome, malnutrition, interference from maternal antibodies and other administered vaccines, etc.

We previously demonstrated that in Ifnar1-/-Ifngr1-/- or Stat1-/- suckling mice lacking intact type I and type II interferon (IFN) signaling, rhesus rotavirus (RRV) infection causes a lethal disease with clinical manifestations similar to biliary atresia, including acholic stools, oily fur, growth retardation, and excess mortality. Elevated levels of viral RNA are detected in the bile ducts and liver of diseased pups together with severe inflammatory responses in these tissues. However, the viral determinants and the molecular mechanisms driving this process remain incompletely understood.

Diarrheal disease continues to be a major cause of global morbidity and mortality among children under 5 years of age. To address the current issues associated with oral attenuated rotavirus vaccines, the study of parenteral rotavirus vaccines has promising prospects. In our previous study, we reported that rotavirus nonstructural protein 4 (NSP4) did not increase the IgG antibody titer of co-immune antigen but did have a protective effect against diarrhea via the intramuscular injection method.
