“…Though enteric viruses are the smallest enteric pathogens with a low infective dose, they are robust and difficult to detect and inactivate ( Gonzales-Gustavson et al, 2019 ; Farkas et al, 2020a ) hence, they serve as a route of potential health risk at a low exposure dose ( Zwart et al, 2009 ; Zhu et al, 2018 ). Thus, the transmission of human enteric viruses via the water route is becoming more widely recognized as a potential cause of human diseases such as gastroenteritis, encephalitis, meningitis, and hepatitis, among others ( World Health Organization, 2014 ; Tang et al, 2020 ).…”

“…Several studies have detected enteric viruses in seawater, surface and groundwater, municipal wastewater influent, and inadequately treated wastewater effluent ( Saxena et al, 2015 ; Shih et al, 2017 ; Hendriksen et al, 2019 ; Pang et al, 2019 ; Verani et al, 2019 ; Shaheen et al, 2020 ; Tang et al, 2020 ; Farkas et al, 2020a ). However, their occurrence is not limited to those water matrices, but they have also been found in drinking water systems and recreational water ( Umesha et al, 2008 ; Upfold et al, 2021 ).…”

Enteric viruses are common waterborne pathogens found in environmental water bodies contaminated with either raw or partially treated sewage discharge. Examples of these viruses include adenovirus, rotavirus, noroviruses, and other caliciviruses and enteroviruses like coxsackievirus and polioviruses. They have been linked with gastroenteritis, while some enteric viruses have also been implicated in more severe infections such as encephalitis, meningitis, hepatitis (hepatitis A and E viruses), cancer (polyomavirus), and myocarditis (enteroviruses). Therefore, this review presents information on the occurrence of enteric viruses of public health importance, diseases associated with human exposure to enteric viruses, assessment of their presence in contaminated water, and their removal in water and wastewater sources. In order to prevent illnesses associated with human exposure to viral contaminated water, we suggest the regular viral monitoring of treated wastewater before discharging it into the environment. Furthermore, we highlight the need for more research to focus on the development of more holistic disinfection methods that will inactivate waterborne viruses in municipal wastewater discharges, as this is highly needed to curtail the public health effects of human exposure to contaminated water. Moreover, such a method must be devoid of disinfection by-products that have mutagenic and carcinogenic potential.

“…When the cells of Microcystic aeruginosa bind to the sodium hypochlorite molecule, hypochlorous acid is formed, and while the chlorine formed from this acid is consumed by the algae, the acid kills the bacteriophage MS2. However, this process to reduce the virus concentration is influenced by the presence of calcium ions and natural organic matter (Tang et al, 2021 ).…”

“…SARS‐CoV‐2 can transport into wastewater from infected stool and urine and, depending on the treatment method, can remain in the water after the effluent has been treated, as shown in studies discussed earlier in this article. The treated wastewater could be discharged into a containment area (Thakur et al, 2021) where it could spread to people via aerosolization, an infection process discussed in the above paragraph and, if leaching occurs, the virus could contaminate the underlying aquifers and eventually infect people. According to WHO (2017), open defecation areas and pit toilets are used by 900 million people worldwide and this is a problem, especially if the feces is not treated or runs off into other water bodies, and if people drink from these water bodies they could be exposed to SARs‐CoV‐2.…”

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has been detected in untreated and treated wastewater and studies have shown that the concentration of SARS‐CoV‐2 is proportional to the prevalence of the coronavirus disease 2019 (COVID‐19) in communities. This article presents a literature review of the prevalence of SARS‐CoV‐2 in wastewater, its environmental fate, recommended treatment strategies for contaminated wastewater, and treatment challenges to be faced in the future. The environmental fate of SARS‐CoV‐2 in wastewater is not straightforward because it can be a source of infection when present in the treated wastewater depending on the permeability of the wastewater treatment plant containment area, and can also leach into aquifers, which may serve as drinking water supplies. Secondly, there are different practices that can mitigate the SARS‐CoV‐2 infection rate from infected feces and urine. The World Health Organization has recommended the use of ultraviolet radiation (UV), disinfection, and filtration for wastewater contaminated with SARS‐CoV‐2, processes also common in wastewater treatment facilities. This article discusses these strategies referencing studies performed with surrogate viruses and shows that SARS‐CoV‐2 treatment can be complicated due to the interference from other aqueous chemical and physical factors. Considering that COVID‐19 is not the first and certainly not the last pandemic, it is imperative to develop an effective multitreatment strategy for wastewater contaminated with contagious viruses and, preferably, those that are compatible with current wastewater treatment methods.
