Thessaloniki-Sewage: Stabilization signs for viral load (tables)

Signs of stabilization in the concentration of the viral load of SARS-CoV-2 in the municipal waste of Thessaloniki appear in the daily measurements from the beginning of the week, for the research conducted by the Sewage Epidemiology Team of AUTh with EYATH, in collaboration with the Region of Central Macedonia and within the National Network of the National Organization of Public Health (EODY).

As shown in the diagrams presented by APE-MPE, the viral load of sewage was measured on November 25 at the highest value since the beginning of the pandemic and in the following days at a slightly lower level.

Specifically, in the samples taken daily at the entrance of the Thessaloniki Wastewater Treatment Plant, regarding the rationalized values ​​of relative viral load secretion, the average value of the two most recent measurements, ie Monday 29/11 and Tuesday 30/11 is:

Marginally stable (-7%) in relation to the average value of the two immediately preceding measurements of Saturday 27/11 and Sunday 28/11.

Marginally stable (-12%) in relation to the average price of the previous Monday 22/11 and Tuesday 23/11.

“If we look at the price fluctuations in November, we see that from the beginning to the end of the month the viral load more than doubled, which is indicative of the extent of the spread of the virus in the community. Among the high prices during this overall uptrend, there were days when the trend was stabilizing. “Gradually increasing, the viral load reached last week the highest value we recorded since the beginning of the pandemic and the positive reading of the latest measurements is to go from the peak to the stabilization,” the AUTh rector and scientific director told APE-MPE. project, Professor Nikos Papaioannou.

Asked if a prospect of improving the epidemiological picture of the city can be estimated in time, based on the analysis of the measurements, the rector of the Aristotle University of Thessaloniki replied: which amplifies such a development, however the unpredictable factor of the virus mutations can upset the picture, as well as the expected increased mobility at Christmas. The city’s hospitals are under a lot of pressure at the moment and it will take weeks for the pandemic to improve, even if the epidemiological picture is starting to improve. “The measures of self-protection from the exposure of the citizens to the virus are of critical importance, it is not possible for the intensive care units to be full and to live in our daily life as if nothing is happening”.

The coronavirus assessment methodology in municipal waste, developed by the AUTh team, streamlines the measurements of the virus genome concentration based on 24 environmental factors, which may alter the results of the measurements.
