Same. 3 "recent arrivals" with an "unspecified virus of unknown origin" arrived back from the 2019 Thanksgiving holiday in which they had spent 2 weeks in yes, Wuhan, and promptly proceeded to cough on my kid in math class. For 6 days before Christmas he had the highest fever, atypical headache and a slight coof. Then loss of taste afterward. Then the other kid picked it up, then me then the wife. By end of January we were all well again. Then a less severe Delta variant was delivered all at once in late May, 18 months later. I figure we have until next Thanksgiving or Christmas before our T immunity to nucleocapsid becomes deprecated enough to need another round. Unless Fausti straps us down and compromises our immune systems with bioagents.
