Current status for WWTP Brno (31 January 2024)

2024: The January reading showed a significant decline, indicating that SARS-CoV-2 is not, like last year, the main cause of the current respiratory disease epidemic.

2023: After the January decline, there was a resurgence of SARS-CoV-2 RNA levels in February and March 2023 with a peak in March, followed by a decline in the summer period and an expected fall increase with a peak in December 2023.

Currently (16 January 2023)

The amount of SARS-CoV-2 RNA in wastewater in December fluctuated at the level of tens to hundreds of GE/1ml at smaller WWTPs (Břeclav, Kladno) and hundreds at WWTPs of large cities (Prague, Brno), i.e. at a lower level than in the autumn months. Compared to the previous waves of the epidemic, the real incidence of the virus in the population corresponded to orders of magnitude higher numbers of infected people than the clinical tests showed. Control samples taken on January 10, 2023 at the Brno and Břeclav WWTPs showed a significant decrease in the amount of the covid-19 marker in the wastewater. The number of people tested positive also decreased. Wastewater confirms that the current epidemic of respiratory diseases is not caused by covid-19.

Currently (16 December 2022)

The current situation at the beginning of December shows an increase in the amount of the covid-19 marker after its decrease at the beginning of November at the ÚČOV Praha a ČOV Kladno (Vrapice). The amount of SARS-CoV-2 RNA in wastewater in smaller WWTPs (Břeclav, Kladno) is at the level of approx. hundreds of infected persons, in large WWTPs at the level of approx. thousands of infected persons, i.e. the real occurrence of the virus in the population is theoretically an order of magnitude higher than shown by clinical tests. The number of people tested positive increases slightly at the turn of November and December.

Currently (13 December 2022)

The current situation is confirmed by the decrease in the incidence of the covid-19 marker since the second half of October at the Prague WWTP and the Kladno WWTP (Vrapice). The number of people tested positive increases slightly at the turn of October and November. Not updated: At the Brno and Břeclav WWTP, the values of the covid-19 marker in wastewater are decreasing after the increase at the end of October. The latest November data point to a process of stagnation (stabilization of covid-19 marker values) on all lines WWTP.

Currently (25 November 2022)

The current situation shows a continued decrease in the incidence of the covid-19 marker at the Prague WWTP and the Kladno (Vrapice) WWTP since the second half of October, which is accompanied by a decline in the number of positively tested persons. At the Brno and Břeclav WWTP, the values of the covid-19 marker in wastewater are decreasing after the increase at the end of October. The latest November data point to a process of stagnation (stabilization of covid-19 marker values) on all lines WWTP.

Currently (23 November 2022)

The current situation shows a continued decrease in the incidence of the covid-19 marker at the Prague WWTP and the Kladno (Vrapice) WWTP since the second half of October, which is accompanied by a decline in the number of positively tested persons. In Brno and Břeclav, the values of the covid-19 marker in wastewater are decreasing after the increase at the end of October.

WWTP Brno:Control samples taken on 10 January 2023 at the Brno and Breclav WWTPs showed a significant decrease in the amount of the covid-19 marker in the wastewater. The number of persons tested positive also decreased. The wastewater confirms that the current epidemic of respiratory diseases is not caused by covid-19.

Comment (25 November 2022)

WWTP Brno: After a decrease at the end of August 2022, there was an increase during September and October to the highest values so far. However, the ratio to the number of positive tests persons has been inverse since the beginning of the summer, i.e. the virus is present in the population, but does not significantly affect the population's health condition. The October values indicated the end of the next wave and the gradual reduction of the amount of the covid-19 marker in the wastewater. At the same time, the number of positive tested people is also decreasing. At the end of October, an increase in the amount of the SARS-CoV-2 marker in wastewater was detected, followed by a further decrease. The November data is showing stabilization (stagnation) of the covid-19 marker values.

ÚČOV Praha - SVL (current) and NVL (new water line): In October 2022, an autumn epidemic wave was caught in the wastewater, which was no longer accompanied by the occurrence of a significant number of clinical cases. The current situation shows a continued decrease in the incidence of the covid-19 marker, which is accompanied by a decrease in the number of positive tested people.

WWTP Břeclav: The amount of virus particles in the waste water rose to the highest values so far in September. However, the ratio to the number of positive tests has been inverse since the beginning of the summer, i.e. the virus is present in the population, but does not significantly affect the population's health conditions. The October values indicated the end of the next wave and the gradual reduction of the amount of the covid-19 marker in the wastewater.

Kladno WWTP: in the second half of 2022, two epidemic waves were recorded in wastewater, which corresponded to a significantly lower number of clinically confirmed cases than at the beginning of the year. The current situation shows a decrease in the occurrence of the covid-19 marker since the second half of October, which is accompanied by a decrease in the number of positive tested people.
