“…During the 2015 to 2016 season, GII.17 was the second most common genotype (20.0%) after GII.4 Sydney_2012 (55.0%), including at least two GII.P16-GII.4 outbreak strains (GenBank accession numbers: LC153121 and LC153122), which were first detected in Osaka City. 18…”

Norovirus (NoV) is a major cause of viral gastroenteritis, and GII.4 has been the predominant genotype worldwide since the mid‐1990s. During the 2014 to 2015 winter, a rare genotype, NoV GII.17, emerged and became prevalent mainly in East Asia. Over the past two decades, NoV molecular surveillance in Osaka City, Japan, has revealed that NoV GII.17 was detected for the first time in February 2001 and that NoV GII.17‐associated outbreaks remarkably increased during the 2014 to 2015 season, with higher incidence recorded in January to March 2015. Genetic analysis indicated that 28 GII.17 outbreak strains were closely related to the novel GII.P17‐GII.17 variants represented by the Kawasaki308/2015/JP strain, similar to that in other regions. Statistical analysis showed that NoV GII.17 infections were more common in adults than GII.3 and GII.4 infections, suggesting that the affected adults most likely did not have antibodies against NoV GII.17 and the novel GII.17 variant had recently appeared. Regarding transmission, food was one of the most important factors involved in the spread of NoV GII.17 among adults; 61% of GII.17 outbreaks were foodborne, with oysters being the most common vehicle. Interplay between pathogens, hosts, and environmental factors was considered to be important in the 2014 to 2015 NoV GII.17 epidemic.

“…All these four variants have been reported in European countries in the same period 11. In fact, GII.17 strains emerged globally in winter 2014–2015 and were widely detected among most European countries between 2015 and 2016 11. GII.4 Sydney started to be the dominant GII.4 variant in 2012–2013 and has circulated primarily as a recombinant, with GII.Pe (GII.Pe-GII.4 Sydney) being the predominant variant until winter 2015 when GII.P16 variant (GII.P16-GII.4 Sydney) emerged 11 12.…”

“…In fact, the four norovirus outbreaks were caused by different strains, namely GII.17 (outbreak 1 in October of 2015), GII.Pe-GII.4 Sydney (outbreak 2 in January 2016), GII.P2-GII.2 (outbreak 3 in November 2016) and GII.P16-GII.2 (outbreak 4 in January 2017). All these four variants have been reported in European countries in the same period 11. In fact, GII.17 strains emerged globally in winter 2014–2015 and were widely detected among most European countries between 2015 and 2016 11.…”

“…The subsequent year, the ECDC and its HEV expert group further developed the concept of the database in collaboration with The National Institute for Public Health and the Environment (RIVM). RIVM already hosted pathogen-specific online databases such as HAVnet (for hepatitis A viruses) and NoroNet (for noroviruses), which are tools that have supported international investigations of outbreaks and molecular trends through standardisation and sharing of protocols [13-15]. …”

Hepatitis E virus (HEV) is a common cause of acute hepatitis worldwide. In Europe, HEV is a zoonosis transmitted via contaminated pork meat or other pork food products. Genotype 3 is the most prevalent HEV type in the animal reservoir, as well as in humans. Despite an increased incidence of hepatitis E across Europe, much remains unknown about its spread, sources and transmission routes. A One Health approach is crucial to better understand the (molecular) epidemiology of HEV. HEVnet was established in April 2017 as a network and database for sharing sequences and accompanying metadata collected from human, animal, food and environmental sources. HEVnet members working in the public health, veterinary health, food, environmental and blood safety sectors have submitted 1,615 HEV sequences from nine countries as at January 2019. Most are from humans (89%), and sequences of animal (5%), food (6%) or environmental (0.3%) origin are rare. Metadata for human sequences capture mostly sex (93%), year of birth (92%) and sampling (100%); data on region of sampling (37%) and clinical information (hospitalisation 27%, symptoms 20% or mortality 8%) are limited. HEVnet aims to expand into a global network capable of performing cross-sectoral and supranational studies, with a joint repository of molecular and epidemiological data on HEV.
