Summary: The presence of SARS-CoV-2 in wastewater and the potential health risks from exposure to virus-contaminated aerosols were analyzed. The study found a relatively high risk of SARS-CoV-2 infection for wastewater workers via exposure to viral aerosols, with an estimated annual infection risk higher than the WHO recommended level. Further research is needed to determine the role of wastewater in COVID-19 transmission.

Summary: Wastewater-based epidemiology offers an opportunity for real-time monitoring of SARS-CoV-2 transmission. The SEIR model based on wastewater RNA concentrations provides a robust method to estimate the total number of infected individuals in a community, supplementing individual testing and informing policy decisions.

Summary: This study conducted a field trial on the presence of SARS-CoV-2 in wastewater facilities in Beijing after the end of the COVID-19 epidemics. The results showed that the wastewater treatment facility is a large repository for SARS-CoV-2. The viral RNA was still present in hospital sewage for 15 days and in municipal wastewater treatment plants for more than 19 days. The study highlights the persistence of SARS-CoV-2 RNA in wastewater, especially at lower temperatures.

Summary: Sampling raw wastewater from major treatment plants in Qatar, it was found that there was a significant discrepancy between the estimated number of infected people and the officially reported cases. Wastewater-based epidemiology proved to be a more reliable method for assessing the true incidence trend in the population.

Summary: Wastewater-Based Epidemiology is a useful tool for assessing and mitigating COVID-19 outbreaks in specific communities. This study utilized nanopore technology to analyze microbiome profiles in wastewater samples collected from different facilities. The research found that the wastewater microbiome can serve as an indicator for community-wide SARS-CoV-2 surveillance and highlighted a correlation between the enteric bacteria of infected individuals and the presence of the virus in wastewater samples.

Summary: By integrating clinical features and multi-omics data, the authors identified specific gut microbiome patterns associated with disease severity and development of post-acute COVID-19 syndrome. These findings highlight the potential utility of host phenotype and multi-kingdom microbiota profiling as a prognostic tool for patients with COVID-19.

Summary: This study utilized wastewater to monitor SARS-CoV-2 RNA, detecting viral RNA in both the city center and suburbs of Bangkok. A sharp increase in copy numbers was observed in October to November, indicating a potential early warning system for upcoming outbreaks.

Summary: This study conducted long-term wastewater surveillance of SARS-CoV-2 in Yamanashi Prefecture, Japan, using RT-qPCR assay and estimated COVID-19 cases using a cubic regression model. The study found that SARS-CoV-2 RNA was successfully detected in 67% of the samples tested during the surveillance period, with higher detection rates in samples collected in 2022. Finally, 3- and 7-day offset models successfully predicted the trend of COVID-19 cases from September 2022 until February 2023.

Summary: This study aimed to investigate the association between SARS-CoV-2 wastewater concentrations and COVID-19 cases at the community-level, and to assess the integration of this data into a wastewater-based epidemiological statistical model for accurate forecasting of COVID-19 infections. The results show that a VAR(1) model estimated with the original data has the strongest forecasting ability, with forecast accuracy for 1 week, 2 weeks, and 3 weeks in the future ranging from 8.97% to 21.57%.
