The SARS-CoV-2 virus’ genetic material was minimally present in samples taken from wastewater treatment plants in all counties according to the National Public Health Institute (NNK).
Based on these measurements, no significant increase in the number of coronavirus infections is expected in the next 1-2 weeks. The NNK highlighted that infectious virus particles are not present in the wastewater.
The NNK performs environmental monitoring as part of its core tasks. The purpose of national wastewater surveys is not merely research, but to complement other epidemiological surveys to support forecasting.

According to the NNK, a number of international studies confirm that an increase in the number of symptomatic cases in a given community follows an increase in the concentration of hereditary material detected in wastewater within at least 4-10 days.
Testing wastewater is a good tool, because asymptomatic or mildly symptomatic infected people who would not be within the scope of the epidemiological data during traditional screening tests, can defecate the virus’ hereditary material.
