Kern County’s COVID-19 transmission rate went from medium to high last week, according to data from the Centers for Disease Control and Prevention. Of all the counties in California, only Kern, Kings, Madera and Merced had a high rate of transmission. Most were at the mid level, and many coastal and northern California counties were at the low level.
The CDC uses three rankings to measure community levels of COVID-19 by county across the United States. On a map, counties colored in green are identified as having low transmission rates; yellow indicates medium transmission rates and orange-colored counties have high transmission rates.
