Researchers had previously detected new coronavirus RNA fragments in untreated sewage from two sewage treatment plants in southeastern Queensland, the communique said. The new study, published in the American Journal of overall environmental science recently, further tested seven methods to extract new coronavirus information from sewage, and determined the most economical and efficient one. Currently, the processing time of each sample is only 15 to 30 minutes.
Studies have shown that analysis of sewage samples can provide insight into the prevalence of new coronavirus infection in the community, whether or not someone has already experienced symptoms of infection. Larry Marshall, chief executive of CSIRO, said the findings will help communities avoid a second outbreak as prevention and control measures are gradually relaxed.
Previous studies have shown that global sewage treatment plants can monitor the virus infection of 2.1 billion people, while the combination of sewage based monitoring and clinical testing can save billions of dollars. For countries and regions with limited resources, sewage based epidemic research may be the only feasible way to effectively monitor the virus.
According to the communique, the results of this study will be shared with the new global cooperation project covid-19 sewage based epidemic research cooperation to help prevent and control the new outbreak.
