SALT LAKE CITY — Each of these charts shows the weekly number of new cases in five counties with more COVID-19 cases than any others. A red line is marked on each for March 17, the day the Governor implemented his statewide “Stay Safe, Stay Home” directive.
You can see Summit, Davis and Weber Counties following exactly the trajectory hoped, but keep in mind it can take two weeks or so for symptoms to start. By the end of March, Summit County peaked in the number of new cases. So did Weber County, while Davis saw increases for a bit longer. But all three counties seem to show that social distancing limited an initial spike in cases.
The two most populated counties have not had such a clear positive trend. Salt Lake and Utah Counties both dipped markedly between 2 and 3 weeks following the directive, but then set off on a sharp, increased trajectory.
In the video above, you’ll see the paths of other counties.
