Detecting variants in wastewater is challenging if the RNA concentration is low, for example, due to
low infection numbers in the catchment area of the wastewater treatment plant. Estimates of the
proportions of variants are less reliable in this situation.
low infection numbers in the catchment area of the wastewater treatment plant. Variants with very
similar mutation profiles can also be harder to distinguish. Estimates of the proportions of variants
are less reliable in these situations.
