Jefferson County now has a total of 13 positive cases of the COVID-19 coronavirus, according to the Jefferson County Health Department.

The Health Department reported six more confirmed cases today (March 26).

As of Wednesday evening (March 25), there were seven cases, so the number of cases nearly doubled in the last day, the report said.

The new cases include four male residents, one in his 20s, one in his 30s, one in his 40s and one in his 50s. The other two cases are females, one in her 30s and the other in her 50s.

According to a written statement from the Health Department, all the cases are under investigation.

Brianne Zwiener, communications specialist with the Health Department, said the agency will not report where the patients with the positive tests live.

“Our Public Health Preparedness team has begun contact investigations and notifications regarding these cases. Those identified as coming into contact with the positive case will be notified individually,” the Health Department reported.

A total of 23 county residents have tested negative for the virus, and 22 test results are pending, according to a social media post by the Health Department.

Kelley Vollmar, director of the Health Department, said during a March 26 meeting she believes there is community spread in the area, and test results will soon be reflecting those cases. She said with the new Mercy testing location in Hillsboro, she believes the positive test numbers will soon increase.

“Don’t be surprised to see larger numbers,” Vollmar said.

The first three confirmed cases in the county were announced Monday night (March 23) during the Jefferson County Council meeting, which was held over the phone.

Those positive results were for a man in his 60s, a woman in her 60s and a woman in her 70s.

According to a Health Department report, one of the cases is contact-based and the other two are under investigation.

The fourth case was announced Tuesday night (March 24). That case is a female between 10 to 20 years old, and it is travel-related. That person has been in isolation with her family since returning from travel, according to the Health Department.

Cases announced on Wednesday include a male in his 50s, a female in her 20s and a female in her 30s, according to a written statement from the Health Department.

The male in his 50s and the female in her 20s are travel-related cases, and the other is under investigation, the report said.
