Sounds like the delta variant ...
I saw that yesterday. A friend of my partner just moved back from Sarasota (next county over) and she's one of those super paranoid about getting sick (even though she historically has had a great immune system) and she's been fully vaccinated for months. I sent her the article and she's happy she got out.
The county is having this outbreak sequenced and they will have results next week. I guess there is some possibility that it's a new strain. But whatever the strain is, it's no match for the vaccine. Employees who were vaccinated and exposed are fine, but it appears to be extremely contagious among the unvaccinated.
