On December 20 the CDC said omicron was estimated to make up more than 73.2% of the new cases as of December 18, now the CDC says just 22.5% of new cases were estimated to be omicron as of December 18. CDC now changes the quarantine rules from originally 14 days to 10 days now 5 days. Is this Science or stupidity? And I’m vaccinated ,but just trying to figure it out.
