“…In contrast to adenovirus, rotavirus material was present in much lower proportions of our samples (31 samples with rotavirus vs 60 with adenovirus), and this corroborates with the findings of other authors who did similar testing and found rotaviruses much less present than adenoviruses in surface water contaminated with sewage [42]. Although it is difficult to compare the results from different parts of the world, it might be speculated that this result is due to the lower occurrence of such viruses in the human population, as well as their structure [11].…”

Testing for viral material in water of public bathing areas of the Danube during summer, Vojvodina, Serbia, 2014

From August to September 2014 a water quality study was conducted on five popular public Danube beaches in Vojvodina, Serbia. To assess the safety of Danube water for bathing, physical, chemical, bacteriological tests were performed. While many parameters for monitoring the quality of water are regulated by law, there are neither national nor international legislations addressing the presence of viruses in recreational waters. In this study, we performed analyses that surpassed national requirements, and investigated if adenovirus, enterovirus or rotavirus genetic material was present in samples of recreational water collected for quality monitoring. Of 90 water samples obtained during the study, enterovirus material was not found in any sample, but adenovirus and rotavirus genetic materials were respectively detected in 60 and 31 samples. Statistical analyses showed a significant correlation between adenovirus DNA and total coliforms in the water. Even when water samples were adequate for recreational use, adenoviruses were detected in 75% (57/76) of such samples. Our results indicate that implementation of viral indicators in recreational water might be helpful to better assess public health safety. This might be particularly relevant in areas where urban wastewater treatment is insufficient and surface waters affected by wastewater are used for recreation.

“…Indeed, high viral contents during the cold season (mainly February, March and April) and relatively low viral contents during the hot season (mainly July, August and September). The last results were similar to those reported in two recent studies in China and in Uruguay that showed the abundance of RVA in wastewater during the cold season . However, in Egypt, the peak of Rotavirus infection was registered between July and November .…”

The main objectives of this work are: firstly, the study of the circulation of Rotavirus A (RVA) in wastewater sampled from a semi‐industrial wastewater pilot plant. The plant is situated in a residential area of Tunis and irrigated by three different neighboring hospitals; and secondly, the evaluation of the functioning of two wastewater biological treatment procedures (natural lagoons and biodisks) in a semi‐industrial pilot plant for RVA removal using molecular characterization and quantification technology. A total of 102 wastewater samples were collected from two biological treatment processes in a semi‐industrial pilot plant that receives effluents of the sewage system of Tunis City (Tunisia). RVA was detected and quantified in 51 wastewater samples (50%) from the pilot plant. The mean values of viral content (genome copies/μL) obtained in the effluent of the two treatments procedures showed a significant decrease in the prevalence and viral content of RVA observed from upstream to downstream of the studied procedure: natural lagoons and at the exit of the biodisks line. The main G‐type was G8 (35.5%), followed by G9 (16%), G1 (13%), G10 (10%), G3 (13%) and three mixed combined genotypes: G3/G9 (3%), G8/G10 (3%), G9/G8 (6.5%) were identified. The data obtained in this study represent the first documentation in Tunisia dealing with the effectiveness of wastewater biological treatment for the removal of RVA through two biological treatment procedures in a semi‐industrial pilot plant located in the area of Tunis (Tunisia).

“…AstVs, NoVs, and RVC have been detected in different types of water, such as drinking water (Kukkula et al 1999;El-Senousy et al 2014), sewage (Meleg et al 2008;Kitajima et al 2012, El-Senousy et al, 2014, seawater (Yokoi et al, 2001;Victoria et al 2014), rivers (Kitajima et al 2010;El-Senousy et al 2015;Prevost et al 2015) and recreational waters (Taylor et al,2001;Vieira et al 2012). Because these viruses can be excreted at a high concentration (10 9 -10 15 particles/g) in the feces of infected patients (Zhang et al 2006;Ludwig et al 2008 ), investigation of municipal wastewater samples could be an effective tool to understand the actual frequency and distribution of these viruses (Gofti-Laroche et al 2003;Scarcella et al 2009).…”

In this study, the prevalence of astrovirus (AstV), norovirus (NoV), and group C rotaviruses (RVC) were described in urban sewage, sewage sludge, river water, and sediment samples from Egypt. AstV, NoV, and RVC were detected in 58.3%, 33.3%, and 25% of the raw sewage samples; in 33.3%, 25%, and 16.6% of the treated sewage samples; and in 66.6%, 16.6%, and 8.3% of the sludge samples, respectively. On the other hand, AstV, NoV, and RVC were detected in 25%, 16.6%, and 8.3% of the river water samples and in 16.6%, 8.3%, and 0% of the river sediment samples, respectively. The study revealed that AstV genogroup B and NoV genogroup I are the most frequent genotypes in the Egyptian environment. Furthermore, the peak prevalence of AstV and RVC in river water and raw sewage samples was found in winter months however there was no clear seasonality for NoV spread. This study support the importance of considering viral markers to ensure the quality of water and the utilization of these markers as additional tests for the characterization of water contamination.

Gastroenteric virus dissemination and influence of rainfall events in urban beaches in Brazil

Abstract: This study provides data on virus contamination in recreational waters on tourist beaches frequented throughout the year, emphasizing the importance of viral parameters for assessing microbiological quality of water, as well as the potential risk of waterborne infections.
