In the past few weeks, as more and more vaccines are rolling out, and with a competent administration leading the country, COVID-19 is finally being dealt with. Much of California is starting to recover, with most of its counties leaving the purple tier category. However, much of the Central Valley still remains purple. Despite that, the Central Valley is now nearing to moving below in the red tier. Tulare county, surprisingly, has managed to become red already.
The rest are to join in soon as well (people permitting). The most significant statistic to keep an eye out for is infections per 100K, in which less than 8 per 100K is the threshold for exiting purple tier. Central Valley counties are barely hovering in 2 digit territory, at 12 or less infections per 100K (while Tulare is at 7.8, just barely within the limits).
