Chesterfield County is a county located in the U.S. state of South Carolina. As of the 2010 census, its population was 46,734, and its estimated 2018 population had declined a little to 45,754.  Its county seat is Chesterfield.  The largest town in the county is Cheraw. Chesterfield County is part of the Charlotte Metropolitan Area. It is located north of the Midlands, on its border with North Carolina.
The county was erected (formed) in 1785, but was part of what was then known as Cheraws District until 1800, at which time Chesterfield became a district itself. Under the post- American Civil War (1861-1865) state constitution of 1867, passed during the Reconstruction era, South Carolina districts became counties with home rule. The county is named for Chesterfield County in Virginia.
On April 10, 2020 a case of Influenza A virus subtype H7N3 was confirmed in what The Post and Courier describes as "a commercial turkey flock" which resulted in the disinfecting & quarantine of the farm.  This is the 1st confirmed case of H7N3 in The United States nationwide since another case was found in Lincoln County, Tennessee on March 5, 2017.  Four days later on April 14, a second case was confirmed at a turkey farm in Jefferson resulting in the euthanization of 32,000 turkeys.  Clemson University released the map of the control area for the first turkey farm infected by the virus on May 4.
