No they didn’t. 5 days of “normal activities with precautions” is not 5 days of “isolation”.
And the core problem is that 5 days was already not scientific and “fever” isn’t an indicator of infectiousness at all, it’s just a symptom that some infectious people experience for some of their infectious period.
“We showed that among the SARS-CoV-2 Omicron variant infected patients, viral shedding continues for ≥10 days in 13.5% of all cases and 11% in symptom-free cases. The decision for cessation of isolation according to the presence of symptoms could be reconsidered until further studies disapprove of our results.”
Unfortunately, not everyone (single mothers?) has the luxury of taking a week off whenever they want or even NEED to.
The CDC changing he recommendation doesn’t do anything for people who might need to leave the house for supplies or to pick up a child. They already could and would do that, because a recommendation to private citizens is just a recommendation. Where it matters is that it removes liability from their employers and “lets” them work, but that’s only “helpful” because so many people are desperately poor and they haven’t mandated paid sick leave when people have infectious diseases. This is the sort of “helping workers” where the help is just because they do absolutely nothing to require humane conditions from their employers. Taking a week off to not infect your fellow workers shouldn’t be a “luxury”.
