During week 46, the average SARS-CoV-2 concentration in wastewater remains high, and most samples show a stagnant trend, NKK added.

However, a decrease was observed in two cities: Szekszárd (145 km south of Budapest) and Szolnok (105 km southeast).

Concentrations of coronavirus measured in wastewater have also increased in most sampling sites over the past week, NKK said.
