Detected coronavirus variants in wastewater
Wastewater monitoring can determine variations in the proportions of different coronavirus variants in Finland.
The coronavirus RNA levels are currently examined 1-4 times a month in ten localities: at the wastewater treatment plants in Espoo, Helsinki, Joensuu, Jyväskylä, Kuopio, Oulu, Rovaniemi, Tampere, Turku and Vaasa.
A portion of wastewater samples in which coronavirus RNA is detected are sent for sequencing in case of coronavirus variants. The results of sequencing are reported to this page as soon as the sequencing is complete.
Variants with asterisks in the graphs also contain their sublineages.
