THESSALONIKI -- The SARS-CoV-2 viral load in sewage samples from the city of Thessaloniki is essentially unchanged since early January, according to a weekly report issued on Wednesday, based on measurements taken by scientists at the Aristotle University of Thessaloniki (AUTH) in collaboration with the city's water and sewage company, EYATh.
The samples taken on January 13, 15 and 18 showed that after a week, the viral load remained at the same level. Consequently, this means the viral load in the sewage is essentially unchanged, with only marginal fluctuations, since the start of 2021.
"Even allowing for the longest time period required, according to the literature, for the shedding of the viral load since the time of infection, there is no indication that the virus is spreading in the city since the beginning of the year. The epidemiological picture has not worsened, not even on Epiphany when concerns were raised over incidents of crowding that were observed," said AUTH rector and head of the project, Nikos Papaioannou, talking to the Athens-Macedonian News Agency (ANA).
