The noroviruses belong to the Caliciviruses family . These viruses have a short incubation time, infected individuals show symptoms within the first two days. Most individuals have symptoms for less than a week and recover quickly, but in frail and elderly individuals´ noroviruses can cause serious health effects. The norovirus GG2 is commonly called "winter vomiting disease virus" and appears seasonally during winter, it often spreads in hospitals, nurseries, and schools ([more info](https://www.folkhalsomyndigheten.se/smittskydd-beredskap/smittsamma-sjukdomar/calicivirus-noro-och-sapovirus/)). Wastewater contains many different human viruses present in feces or urine shed from infected persons. Previous studies from the Norder group (Hellmér et al, 2014) has shown that this could be used as a predictive measure of upcoming outbreaks caused by norovirus GG2. Previous studies from the Norder group have shown that the amounts of noroviruses in wastewater increased 1-2 weeks before larger outbreaks in nursery homes and hospital wards. Other human pathogenic viruses, not routinely investigated for, were also identified in the wastewaters. +Enteric viruses are a large group of viruses including, for example, calicivirus (including norovirus and sapovirus), adenoviruses, and astroviruses. They are transmitted via faecal-oral route, and cause enteric disease (i.e. diseases with symptoms such as nausea, diarrhea, and vomiting). -At the start of the COVID-19 pandemic in 2020, the Norder group restarted these analyses. Simultaneously with investigating for SARS-CoV-2 the presence of a number of other viruses eg. Pepper molt mild virus (PMMoV), adenovirus, norovirus GG2, sapovirus, astrovirus, and enteroviruses including poliovirus are measured weekly. From the beginning of 2023 results from norovirus will be shared with weekly on the Pandemic Preparedness Portal. Data from other viruses will also be shared later. +Wastewater contains many different types of viruses that infect humans, as such viruses are shed in the faeces and/or urine of individuals infected with the virus. The Norder group at the University of Gothenburg showed that the relative levels of some enteric viruses could be used to predict upcoming outbreaks ([Hellmér _et al._, 2014](https://pubmed.ncbi.nlm.nih.gov/25172863/)). Indeed. previous studies by the Norder group have shown that the levels of noroviruses in wastewater increase 1-2 weeks before larger outbreaks in nursing homes and hospital wards. + +In 2023, the Norder group at the University of Gothenburg (GU) commenced weekly monitoring of the levels of some enteric viruses in wastewater. Specifically, they began to quantify the relative levels of enteroviruses (including poliiovirus), pepper molt mild virus (PMMoV), adenoviruses, GG2 (a norovirus), astroviruses, and sapoviruses. This monitoring was done alongside their ongoing monitoring of SARS-CoV-2 in wastewater, the data for which is [shared on this portal](dashboards/wastewater/covid_quantification/covid_quant_GU). The Norder group now also share data from their monitoring of enteric viruses on this portal. The project is led by Professor Heléne Norder (University of Gothenburg, GU), and supported by co-workers from the University of Gothenburg and Sahlgrenska University Hospital (Hao Wang, Marianela Patzi Churqui, Timur Tunovic, Fredy Saguti, and Kristina Nyström). The wastewater sample collections are performed by Lucica Enache at Ryaverket, Gryaab AB, Gothenburg. -The data and visualisation on this page are usually updated weekly. +The data and visualisations on this page will be updated approximately weekly. + +### Basic virus information + +**Enteroviruses** comprise of a group of around one hundred viruses of the _Picornaviridae family_. This group includes, for example, Enterovirus A-D (which includes Poliovirus (type 1-3)), Coxsackievirus (group A and B), Echovirus, and Enterovirus. Non-polio enteroviruses typically cause only mild symptoms akin to those caused by the common cold. + +**Adenoviruses** are part of the _Adenoviridae family_. There are seven human adenoviruses (A to G) and >60 (sero)types. They often cause acute viral gastroenteritis (diarrhea and vomiting) in children under 5, but this is rare in adults. + +**Noroviruses**, including GG2 (more commonly known as the "winter vomiting disease virus"), belong to the _Caliciviruses_ family of enteric viruses. They have a short incubation time, and infected individuals show symptoms within the first two days. Most patients recover quickly, and experience symptoms for less than a week. However, there can be more serious effects on the health of those in certain groups, including individuals that are immunocompromised. GG2 cases are seasonal, with cases peaking in winter. It often spreads most where individuals come into close contact, such as in hospitals, nurseries, and schools. See [Folkhälsomyndigheten](https://www.folkhalsomyndigheten.se/smittskydd-beredskap/smittsamma-sjukdomar/calicivirus-noro-och-sapovirus/) for more information. + +**Astroviruses** are part of the _Astroviridae family_, which includes eight serotypes (HAst1-8). Patients infected with astroviruses often experience mild diarrhea for a few days. Other symptoms could include a headache, malaise, nausea, vomiting, and a mild fever. Cases of astrovirus infection are most common in winter and spring. Healthy individuals typically acquire immunity after infection, so reinfections are rare. ## Wastewater collection sites -Weekly wastewater samples for virus analysis are collected daily at Ryaverket's wastewater treatment plant in Gothenburg. The Ryaverket treatment plant receives wastewater from all households in Gothenburg, which includes 790,000 inhabitants, as well as from industry in the area. Wastewater is also treated from industry and residents in surrounding municipalities, including Ale, Härryda, Kungälv, Lerum, Mölndal and Partille, as well as storm and snowmelt water from older parts of Gothenburg. The amount of wastewater from households is relatively constant throughout the year, but overall the volume varies significantly depending on the weather as higher rainfall results in larger amounts of wastewater. Therefore, the samples to be analyzed for viruses are flow-weighted, so that the amount of collected and analyzed wastewater relates to the flow of incoming wastewater, which means that the amount of analyzed wastewater collected during a week varies between 1 L -15L. More information on this can be found in Hellmér et al., (2014) and Wang et al. (2022). +The wastewater samples for virus analysis are collected at Ryaverket's wastewater treatment plant in Gothenburg (see the methods section below for details).
