What determines high or substantial transmission?

Has the CDC ever released any data on those thresholds or were the numbers just plucked out of thin air?

Do those definitions which are based on case counts matter anymore? Now that we have 3 approved vaccines that are widely available and there has been a de-linkage between the old math of cases - hospitalizations - deaths why have are we still looking at cases. The percent of hospitalizations per case has gone way down.

      - I certainly expect (hope) that this will work with deaths - ufl 2021-08-02 14:43:01
        It is evident in the UK data, but not in the Florida data - Father Nieuwland 2021-08-02 14:56:24
        Also evident in the NL data - ndhouston 2021-08-02 15:36:30
        I expect a smart quant guy will probably construct a formula - Father Nieuwland 2021-08-02 15:42:03
        You'll need to account for vax distribution as well - ndhouston 2021-08-02 15:49:27

  - Hospitalizations are a lagging indicator. - ndroman21 2021-08-02 14:03:12
    - As I said - but you can't use last year's case numbers - mintirish 2021-08-02 14:10:22
      - Do we have data on Delta in a partially vax'd populace? - ndroman21 2021-08-02 14:29:47
  - We used those numbers as well. - ewillND 2021-08-02 13:46:35
  - Probably via a committee of public health experts - vermin05 2021-08-02 13:33:16
    - They are not new - mintirish 2021-08-02 14:12:02
      - Since the vast majority of cases are amongst the unvax'd.... - ndroman21 2021-08-02 14:31:51
        but we are talking about vaccinated people wearing masks - mintirish 2021-08-02 14:53:55
