*As the sample is stratified by region, age group, and gender, the estimation of prevalence is not based on the simple arithmetic mean but the corresponding weighted mean.

*In waves 16 and 17, also post-stratification based on vaccination information was used. This means that the actual vaccination level according to the Health Board was also taken into account in calculating the weighted average.
