Anderson County has reported 89 new COVID-19 cases in a week as the infection rate increases and officials across the country warn of the spread of the delta variant, especially among the unvaccinated. The increase in Anderson County mirrors what is happening across Tennessee, where new cases have surged from a few hundred each day to more than 2,500 each day while hospitalizations have more than quadrupled.
The positivity rate, a measure of the positive tests each day, has been 10 percent or higher in Anderson County four times since July 12. It hit a high of 24 percent on July 20, according to data from the Tennessee Department of Health. Ten percent is high, and World Health Organization guidelines have called for keeping the positivity rate below 5 percent.
The county’s 89 new cases in a week, from July 22 to July 28, is an average of 12.7 new cases per day. That average is 32 times higher than the low seven-day average of 0.4 new cases per day reported about three weeks ago, on July 6.
The seven-day new case average is now the highest it’s been about since about March 23. That’s when COVID-19 cases were in the middle of a slow months-long decline after a winter peak in November, December, and January.
