“…Although G8 and G6 are common in bovines [ 22 ], G8 is also found in oysters and shellfish, although it does not infect them [ 38 ]. In Bangladesh, the predominant genotype (> 94%) among 200 diarrheic calves was G6P[11] [ 39 ], while during 2017–2019 in India, G6P[14] and G8P[14] were the most common RVA genotypes in bovines [ 40 ].…”

Rotavirus group A (RVA) is characterized by molecular and epidemiological diversity. To date, 42 G and 58 P RVA genotypes have been identified, some of which, like P[14], have a zoonotic origin. In this study, we describe the epidemiology of unusual RVA genotypes and the molecular characteristics of P[14] strains. Fecal samples from children ≤ 16 years of age with acute gastroenteritis (AGE) who were hospitalized during 2007–2021 in Greece were tested for RVA by immunochromatography. Positive RVA samples were G and P genotyped, and part of the VP7 and VP4 genes were sequenced by the Sanger method. Epidemiological data were also recorded. Phylogenetic analysis of P[14] was performed using MEGA 11 software. Sixty-two (1.4%) out of 4427 children with RVA AGE were infected with an unusual G (G6/G8/G10) or P (P[6]/P[9]/P[10]/P[11]/P[14]) genotype. Their median (IQR) age was 18.7 (37.3) months, and 67.7% (42/62) were males. None of the children were vaccinated against RVA. P[9] (28/62; 45.2%) was the most common unusual genotype, followed by P[14] (12/62; 19.4%). In the last two years, during the period of the COVID-19 pandemic, an emergence of P[14] was observed (5/12, 41.6%) after an 8-year absence. The highest prevalence of P[14] infection was seen in the spring (91.7%). The combinations G8P[14] (41.7%), G6P[14] (41.7%), and G4P[14] (16.6%) were also detected. Phylogenetic analysis showed a potential evolutionary relationship of three human RVA P[14] strains to a fox strain from Croatia. These findings suggest a possible zoonotic origin of P[14] and interspecies transmission between nondomestic animals and humans, which may lead to new RVA genotypes with unknown severity.

“…Studies carried out on mussels and oysters in Brazil in Arraial, in Rio de Janeiro, reveal in the sequencing of the VP6 gene of RV the identification of the I2 genotype, which presented high homology with human strains of the G1P [8] and G3P [8] genotypes isolated in Brazil, Taiwan, Australia and the Dominican Republic; Another investigation carried out in the coasts of the Brazilian Amazon identified the I2 genotype of RV in mussels and cultured oysters [53]. In Argentina, this I2 genotype was detected in oyster samples, associated with G8-P [1]-I2, which has a genome similar to that of bovine RV [44]. Investigations carried out in Brazil have detected the VP6 gene of RV genotype I2 in stool samples from children in that country [68,69].…”

“…Studies have shown the presence of RV in berries, vegetables, and oysters (Crassostrea gigas) in Argentina [43,44,45]. In Chile, a pilot study was used for the first time in Latin America by studying the RNA virosphere using a single wastewater sample in Santiago de Chile using viral metagenomics, demonstrating high RV content [46].…”

Rotavirus is considered a major public health problem worldwide because many children, adults, and animals die from gastroenteritis due to rotavirus; rotavirus contamination follows the fecal/oral route, and it is well supported that infection can also be achieved by consuming food and water that is contaminated with rotavirus. Research has shown that, in Latin American countries, unusual emerging strains of rotavirus are occurring in children and adults with gastroenteritis; which contain in their sequence genes from rotavirus genotypes detected in animals; Therefore, researchers consider it a virus with zoonotic potential. In this review, I propose that rotavirus transmission occurs from wild animals, who use an intermediate host before contaminating humans, by means of the fecal/oral route, food, and water. Rotavirus produces genetic rearrangements generating new emerging strains, which are excreted into the environment. Generally, during the dry season in our Latin American countries, contaminated water is used to irrigate crops, and from there, much of this water ends up in the sea, where rotavirus is absorbed by filter-feeding molluscs, and from there, consumed by man and animals continuing its cycle. Studies on the molecular characterization of rotavirus strains detected in food and water provide new insights into possible rotavirus genetic rearrangements and zoonoses. The emergence of strains derived from interspecies transmission has implicated and inspired the study of different vaccine strategies.

“…Mozgovoj et al (2022) (32) showed that virus particles remain infective in oysters and that consumers may be at risk of infection. These results constitute a warning and justify the need to strengthen the surveillance of foodborne viruses in order to better understand their circulation in our country and to improve the control protocols for seafood products.…”
