William and Mary didn’t post new numbers over spring break. You also might want to take the most recent numbers with a grain of salt, again due to the impact of spring break (and the potential for cases to have occurred over spring break, but not be reported to W*M).
Those caveats aside, taken at face value, the new-case rate on the William and Mary campus now appears to be on a par with the rate for 18-24 year olds, generally, in Virginia. Really, the new case rate is so low (under one per day, as I calculate it, for this last reporting period) that, effectively, you’re looking at two numbers that are effectively zero, plus some random statistical noise.
Source: Calculated from William and Mary COVID-19 dashboard. I gap-filled the 3/14/2022 number by taking the average of the week before and the week after. The 3/21/2022 rate assumes that if cases occurred over spring break, that would have been reported to W&M. No idea whether that’s reasonable or not.
