The number of confirmed COVID-19 cases in Arkansas increased Thursday to 349, including a case in Chicot County, that county’s first confirmed case.

As of 5:30 p.m. Thursday, 42 counties in Arkansas have confirmed cases, including six counties in extreme Southeast Arkansas: Chicot, Drew, Bradley, Cleveland, Desha and Lincoln. There are no confirmed cases in Ashley County, according to the Arkansas Department of Health.

Statewide, 19 people have recovered from the disease and three have died.

“Those who have recovered are being asked to donate plasma at some point,” Dr. Nathaniel Smith, Secretary of the Arkansas Department of Health said at the COVID-19 briefing. “One of the more promising approaches to treating critically ill patients with COVID-19 is to give them plasma from those who have recovered because it has antibodies that can fight the virus. Obviously the plasma has to be processed and tested so that it is safe to give but that’s a promising strategy.”
