The article wasn’t researched or written very well.
It says the stylists were symptomatic while they cut hair for 8 days. I wonder if “symptomatic” is a typo. Did Missouri encourage sick people to cut hair in mid-May? The story would make more sense if they were actually “asymptomatic”.
If they were really symptomatic, a good reporter would tell us their symptoms. Did they have fevers? Did they have mild symptoms consistent with spring allergies? Were they coughing up a lung?
As expected from incompetent CNN, the story doesn’t tell us what kind of masks were worn. That’s probably an important detail.
The story boils down to “people did stuff and stuff happened”. But CNN got to use some scary pictures with patients on stretchers and folks in haz-mat suits.
