Continuous improvement of the epidemiological picture of Thessaloniki It occurs between measurements in wastewater from the urban complex, in research carried out by an interdisciplinary team from the Aristotle University of Thessaloniki in collaboration with EYATH.

“From measurement to measurement and after rationalization of measurements, depending on the environmental characteristics of the wastewater, there is a continuous reduction in the rate of viral load secretion,” its rector told APE-MPE. AUTH and scientifically responsible for the research project, Prof. Nikos Papaioannou. “The value of the viral load secretion rate on Wednesday, November 25, was approximately 30% lower than the value of Monday, November 23,” the rector of the Aristotle University of Thessaloniki announced the result that emerged on Friday afternoon. , after the implementation of multidimensional environmental rationalization. of measurements, developed by the AUTh team.

“All this shows that we are doing better, but in no case we are complacent, since we hope that the improvement will be consolidated after at least one week to ten days. You have to be very careful in the coming days to observe the measures, the slightest complacency is enough to reverse the good course ”, added the rector of AUTh.

As he explained, when looking at the diagram that shows the viral load measurements in Thessaloniki’s wastewater since the beginning of the epidemiological outbreak, it is found that “we are still” in the red “and specifically at the levels where we measure the viral load rate. at the beginning of November, when the cases announced by EODY for the city were at the level of 500 and above.

In the corresponding diagram of the Aristotle University of Thessaloniki, presented by APE-MPE, the sampling days registered in red correspond to more than 500 cases -as announced in the respective days by EODY- the days registered in orange in 100-400 cases and the days recorded in green in less than one hundred cases.

Your valuation methodology coronavirus in municipal waste, developed by the AUTh team, streamlines the measurements of the concentration of the virus genome based on 24 environmental factors, which can alter the measurement results. The research involves professors from 11 different laboratories from the Departments of Medicine, Chemistry, Pharmacy, Veterinary Medicine, Biology, Civil Engineering, Space Engineering and Development of the Aristotle University of Thessaloniki.

The following is the diagram showing the viral load measurements in the Thessaloniki sewage from October 5 to the last measurement
