The SARS-CoV-2 concentration in the sewage of Thessaloniki is marginally increasing, according to research conducted by the Sewage Epidemiology Team of Aristotle University of Thessaloniki (AUTh) with the city’s water board EYATH, in collaboration with the Region of Central Macedonia and within the National Network of National Public Health Organisation (NPHO). High levels of the viral load are being detected, similar to that in the first 10 days of November.
Specifically, regarding the changes seen in the measurements from samples taken daily at the entrance of the Thessaloniki Wastewater Treatment Plant, with respect to the rationalized measurements of viral load secretion, the average value of the two most recent measurements, on Monday, 05/04 and Tuesday, 06/04 is:
– Marginally stable (increase of only 7 pct) in relation to the average value of the two immediately preceding measurements, ie Friday, 02/04 and Sunday, 04/04.
– Increased by 30 pct compared to the average price of the previous Monday, 29/3 and Tuesday, 30/3.
In the week 29/3 – 4/4/2021 there was an increase (+56% pct) in the relative rate of secretion of viral load, compared to the previous week, 22-28/3/2021.
“The consistently high levels of the viral load in the city’s sewage in recent days combined with the excessive pressure on the city’s hospitals show that we remain on the verge of an epidemiological alert. It is important that there is no complacency and relaxation in the observance of the measures, which will lead to further deterioration of the situation,” AUTh rector and scientific head of the research project, Prof. Nikos Papaioannou, said to the Athens-Macedonian News Agency (ANA), stressing the need to remain committed to the goal of reducing the health burden “so that we can return soon to our social and economic activities.”
