 The symptoms were combined in sets that showed positive correlation with cases, especially after Omicron was declared a variant of concern by the WHO. Note that symptoms in _scontrol_ are not COVID-19 related, and this symptom set can be used as a negative control.

 ## Estimation
 Each signal is the average of the
- values of search trends for each symptom in the symptom set. For example, `s06_raw_search` is the average of the search trend values of anosmia, ageusia, and dysgeusia. Note that this is different from the union of
+ values of search trends for each symptom in the symptom set. For example, `s05_raw_search` is the average of the search trend values of anosmia, ageusia, and dysgeusia. Note that this is different from the union of
  anosmia, ageusia, and dysgeusia related searches divided by 3, because the data volume for each symptom is calculated based on search queries. A single search query can be mapped to more than one symptom. Currently, Google does not provide _intersection/union_
  data. Users should be careful when considering such signals.
