The seven-day average of new daily cases of COVID-19 in Anderson County fell Tuesday, a reversal of a trend that had been in place since at least late June.
Still, the average number of new daily cases remained high, and it was higher than it has been in all but the previous week. And it’s not clear yet if the downward trend will continue.
The most recent seven-day average, in the week ending Tuesday, was 18.6 new COVID-19 cases per day. The highest it’s been, the week before, was 24.7. In late June, the county had an average of 3.43 new cases of COVID-19 per day.
Another trend that has reversed, at least for now: The number of active cases in the county fell four days in a row. It was 255 on Thursday. That was down more than 30 cases from a peak of 289 active cases on Sunday. Active cases are total cases minus recoveries and deaths.
In other potentially good news, the daily positivity rate, which measures the percentage of people who test positive for COVID-19 out of those who are tested, has fallen for at least two weeks.
The seven-day average of the positivity rate was 5.5 percent on Thursday. That was about 3 percent lower than the previous week and roughly 4 percent lower than two weeks earlier.
On Wednesday, the daily positivity rate was 2.9 percent. That’s the lowest it’s been since early July. It was higher again on Thursday, 5.6 percent.
In the past month, the daily positivity rate peaked at 20 percent on July 14. It was at 10 percent or higher nine times in July. World Health Organization guidelines say positivity rates should be at 5 percent or lower for at least 14 days before activities re-open.
In Anderson County, the COVID-19 case doubling time has lengthened by several days, up to 16 days from 12-13 days a little more than week ago. That means the number of cases is not increasing as fast.
But there have continued to be hospitalizations and deaths due to COVID-19. Anderson County has had four more deaths due to COVID-19 in the past three weeks, and half of its 30 hospitalizations have been since July 15, or a little more than three weeks.
It’s not clear what led to the declines in the seven-day averages of new daily cases and the daily positivity rate, or whether those trends will continue.
It’s also not clear what impact a slower increase in new cases would have on new hospitalizations and deaths. Health officials and experts say there can be a lag of several weeks between changes in new cases and changes in new hospitalizations and deaths.
On Thursday, the Tennessee Department of Health reported that Anderson County has had 651 total COVID-19 cases since the first infection was reported on March 20. There have been six deaths due to COVID-19 and the 30 hospitalizations.
The number of COVID-19 cases has more than tripled since July 14 and has increased more than six times since July 2, when case growth seemed to accelerate in Anderson County.

COVID-19 is a new, contagious respiratory illness that can be deadly. It can cause a range of health issues that can last weeks or months, including fevers, body aches, fatigue, coughing, and breathing problems, among other reported symptoms. The long-term effects remain unknown.
It can be spread by respiratory droplets from coughing, sneezing, talking, and singing. There is also debate about whether it might be spread by airborne transmission.
The disease appears to be especially deadly to older patients, according to data from the Tennessee Department of Health. There have been at least 10 deaths among all age groups 21 years old and older, and 65 or more deaths starting with the 41-50 age group. The number of deaths continues to climb in older age groups. There have been between 126 and 378 deaths in the four oldest age groups: 51-60, 61-70, 71-80, and 81 and older.
The largest number of cases continues to be among patients who are 21 to 30 years old, followed by patients who are 31 to 40, and then patients who are 41 to 50.
While some people report no symptoms or mild symptoms, others become seriously ill from COVID-19, sometimes for weeks, and the effects can sometimes last for months. Others are admitted to the hospital, and some patients end up in intensive care and on ventilators.
To help prevent the virus from spreading, officials have repeatedly recommended that residents wear a face mask or covering when they are out of the house and around others, maintain a distance of at least six feet from other people when possible, and wash their hands frequently.
