They re investigating sewage to spot the coronavirus. An unusual SARS-CoV-2 early warning system was developed

In preparation for the impending return of students to the university, the rector of the University of Arizona commissioned an analysis of wastewater from dormitories on the campus for the presence of coronavirus .

After a few days, the professor in charge of a research project called indicating that the virus detected in the effluent from the dorm Likins Hall.

The administration immediately reached the dormitory and subjected all persons on its premises to the presence of the coronavirus. They found that there were two of the students who were already carriers, although they had no symptoms.

This is a very valuable way of assessing the situation, allowing for a quick reaction. Being able to detect people who are infected without symptoms is extremely important in preventing the spread of the virus, says Robert Robbins, president of UoA.

In people with COVID-19 , the virus appears in the faeces before they even feel the first symptoms of the disease.

Wastewater monitoring can therefore help public services to detect potential sources of infection.

Similar measures to monitor the spread of the disease have also been implemented in several other US cities, such as New Haven, Connecticut, and Carmel, Indiana.

Every day, employees at the New Haven wastewater treatment plant collect a sample of the waste water, which is then passed on to researchers at Yale University. Scientists use it as the main tool to predict the directions of local development of the COVID-19 pandemic.

Thanks to this, we know what is happening in our city, says Brian Weeks, an epidemiologist using data collected by the Yale team. The research team analyzes samples from the wastewater treatment plant and informs city officials about the virus levels in the wastewater once a week. When we compared the viral wastewater viral load levels with the incidence numbers recorded in the city, it was found that the virus percent increase in wastewater was recorded one week before the contamination surge.

This could be an excellent coronavirus early detection system

With people gradually returning to work, children and young people returning to schools and colleges, specialists expect a significant increase in the incidence of COVID-19 in the coming weeks. The method of early detection of trend changes and coronavirus outbreaks would certainly allow for a better response to the changing situation. With information about an increase in viruses in wastewater in a particular area, additional social distancing measures or other measures could be introduced before the first symptomatic people show up in hospitals.
