The wastewater monitoring technology company KANDO, in collaboration with researchers from Ben-Gurion University and the Technion, announced today (Thursday) preliminary results of a pilot project to detect corona virus outbreaks. The pilot was held in Ashkelon, where the company succeeded Locate evidence of a virus in the city’s sewer system. The findings of the study, conducted throughout the city, indicated Ability for early detection of eruption foci, Up to the level of the neighborhood and even the street.
The city of Ashkelon was chosen as the experimental site, as the number of cases verified in it is relatively low, with the exception of the “Corona Hotels” in the city. However, during the pilot, completely different findings were found: High amount of virus residues in sewage, which were used as a means of early detection of an outbreak in a neighborhood in the city. Detection of virus residues in wastewater is a quicker and earlier means of detection than tests for individuals – especially when the time between infection in the corona and the onset of symptoms are taken into account.
The researchers were able to quantify the information collected and accurately describe the epidemiological and environmental findings. The findings helped target the outbreak area to a particular neighborhood and even individual streets, provide authorities with early detection of outbreak hotspots, allow for much more accurate treatment and avoid extensive closures.
“Identifying corona residues in sewage is extremely challenging, due to the many substances present in the water, such as industrial waste, that can dilute and even destroy the virus residues,” explained Professor Nadav Davidovich, director of the Public Health School at Ben-Gurion University of the Negev. “Our unique methodology allowed us to detect and detect the virus and calculate its concentration taking into account the substances I mentioned. Through integration with epidemiological findings, we were able to accurately locate the outbreaks. Our findings will allow authorities to take action to reduce future outbreaks. In eradicating the corona and other diseases. ”
“Monitoring sewage water is like a blood test for an entire city,” said KANDO CEO Ari Goldfarb. Together with our distinguished partners from Ben-Gurion University and the Technion, we demonstrated that we can provide the authorities with insights that can be used to warn of outbreaks – even before their residents develop symptoms. Our hope is that we will be able to help cities around the world prevent widespread closures and help address future outbreaks. “
KANDO, together with its partners, including world-renowned experts from Ben-Gurion University and the Technion, who come from a variety of fields, such as virology, water engineering, medicine, epidemiology, biostatistics and public health experts, have developed an interdisciplinary method and technology for monitoring sewage network. And advanced “upstream” toward the city itself. The technology uses an array of sensors, placed in many sewers in the city, alongside the use of advanced algorithms and artificial intelligence.
During the pilot, the company used the vast experience it has in analyzing industrial wastewater and together with the researchers, was able to deduce the proportion of the population infected in Corona by using available information, including taking into account factors such as sewage components that may destroy the virus and its flow rate. .
