## Background: Wastewater-based epidemiology

The genomes of many pathogens, including SARS-CoV-2, can be detected in faecal samples collected from infected individuals (e.g. COVID-19 patients) using polymerase chain reaction (PCR) tests (see, for example, [Wu *et al*. (2020)](https://doi.org/10.1016/S2468-1253(20)30083-2)). Monitoring the levels of pathogens (e.g. SARS-CoV-2) in wastewater from communities can therefore provide an indication of the prevalence of that pathogen at a population-wide level, referred to as wastewater-based epidemiology ([Corpuz *et al.*, 2020](https://doi.org/10.1016/j.scitotenv.2020.140910)).
The genomes of many pathogens, including SARS-CoV-2, can be detected in faecal samples collected from infected individuals (e.g. COVID-19 patients) using polymerase chain reaction (PCR) tests (see, for example, [Wu _et al_.

Wastewater, also referred to as “sewage” includes water from multiple sources in each household, including kitchen sinks, toilets, and showers. However, it could also include water from multiple other sources (for example, rainwater and water from industrial use). Samples used for wastewater epidemiology studies are collected periodically at wastewater treatment facilities; enabling assessments of viral load over time. Wastewater monitoring has been shown to be an effective early-warning system for outbreaks. For example, [Peccia *et al.* (2020)](https://doi.org/10.1038/s41587-020-0684-z) showed early on in the COVID-19 pandemic that SARS CoV-2 virus content in wastewater predicted increases in infection in the population and followed the epidemic trend, as measured by the number of COVID-19 cases and hospitalisation rates. More recently, [Wang *et al.* (2022)](https://pubmed.ncbi.nlm.nih.gov/36035197/) showed that the level of SARS-CoV-2 viral genomes in wastewater increased 1-2 weeks before there was an increase in the number of hospitalised COVID-19 patients. During the COVID-19 pandemic, surveillance of viral RNA levels in wastewater has been increasingly used to monitor and predict the spread of the disease.

Wastewater monitoring should primarily be seen as a surveillance system. Taken together with data for infection testing, intensive care admissions etc., it may help in understanding the regional dynamics of disease outbreaks.

## Background

Enteric viruses are viruses that are primarily transmitted via the faecal-oral route, and that cause enteric disease (with symptoms e.g. nausea, diarrhea, vomiting, and abdominal pain). Many families of viruses are enteric viruses, including, for example, *calicivirus (including norovirus and sapovirus), adenoviruses, astroviruses, rotaviruses, hepatitis viruses, and enteroviruses*. Most enteric viruses cause only relatively mild symptoms in healthy individuals, some enteric viruses (e.g. poliovirus) can have serious health effect, with symptoms including meningitis and paralysis. Enteric viruses have been known to cause epidemics, for example, outbreaks of hepatitis A and coxsackieviruses have been reported worldwide within the latest decade.

In the below paragraphs, we provide more detail regarding some examples of enteric viruses.

**Noroviruses** belong to the Caliciviruses family. The norovirus GG2 is more commonly known as the "winter vomiting disease virus". Cases are typically seasonal, with peaks in winter. It is often spread between people in environments where individuals come into close contact, such as hospitals, nurseries, schools, and cruise ships. To read more about GG2, see resources by [folkhälsomyndigheten](https://www.folkhalsomyndigheten.se/folkhalsorapportering-statistik/statistik-a-o/sjukdomsstatistik/calicivirus-veckorapporter/sasong-20222023-for-calicivirusrapporter-vinterkraksjuka/), for example.

**Hepatitis A (HAV)** and **hepatitis E (HEV)** are other examples of enteric viruses. The other four human hepatitis viruses are not transmitted via the faecal–oral route. Outbreaks of hepatitits A, caused by transmission in contaminated food or water, occur regularly. Read more about the 2022 outbreak in [our emerging pathogens section](https://www.covid19dataportal.se/pathogens/hepatitis_unknown_origin/).

The **Enteroviruses** comprise of a group of around one hundred viruses of the Picornaviridae family. Examples include Enterovirus A-D (which includes Poliovirus (typ 1-3)) and Coxsackievirus (group A and B). All three Polioviruses can cause poliomyelitis, more commonly known as polio. There was a major polio epidemic in the early 20th century, polio vaccines were created in the 1950s in response, and mass vaccination programs were quickly implemented. In Sweden, the polio vaccine became part of the routine vaccination program for children in the mid-1960s and there have been no reported cases since the late 1970s. More information about the mass vaccination program is available (in Swedish) from [Folkälsomyndigheten](https://www.folkhalsomyndigheten.se/smittskydd-beredskap/vaccinationer/vacciner-som-anvands-i-sverige/polio/#:~:text=Polio%20i%20Sverige&text=I%20Sverige%20inleddes%20massvaccination%20i,sista%20inhemska%20fallet%20rapporterades%201977), along with more [information about ongoing efforts with polio virus globally](https://www.folkhalsomyndigheten.se/nyheter-och-press/nyhetsarkiv/2022/oktober/varlden-ar-nara-att-utrota-polio-men-har-en-bit-kvar/). Most non-polio enteroviruses will only cause a mild illness, with patients reporting symptoms similar to the common cold with a fever, runny nose, a cough, and muscle aches. Most people recover easily without medical intervention, or with only mild ‘over the counter’ remedies. A number of outbreaks of non-polio enteroviruses, such as coxsackieviruses, have been reported within the latest decade. Information about the surveillance for outbreaks of non-polio enteroviruses is available from [American Centers for Disease Control and Prevention (CDC)](https://www.cdc.gov/non-polio-enterovirus/outbreaks-surveillance.html).

**Adenoviruses** are part of the Adenoviridae family. There are seven human adenoviruses (A to G) and >60 (sero)types, some of which are water-borne. These viruses commonly cause gastroenteritis among children younger than 5.

**Astroviruses**, part of the Astroviridae family comprise of eight serotypes (HAst1-8) causing gastrointenstinal symptoms. Most enteric viruses do not give immunity, but astroviruses are an exception, with healthy individuals generally acquiring immunity after infection, making reinfection rare.
The [National Respiratory and Enteric Virus Surveillance System (NREVSS)](https://www.cdc.gov/surveillance/nrevss/index.html) is an American surveillance program that monitors many enteric viruses. They monitor respiratory syncytial virus (RSV), human parainfluenza viruses (HPIV), human metapneumovirus (HMPV), respiratory adenoviruses, human coronavirus (excluding SARS-CoV-2), rotavirus, and norovirus.
