The woman suffered a medical emergency in her cell on Aug. 31 and was taken to the hospital, where she was pronounced dead on Thursday, police said.
The Fairfax County Sheriff's Office, which runs the jail, said in a news release that a sheriff's deputy called a medical emergency for the woman around 7 p.m. on Aug. 31 after she suddenly became ill.
The woman was transported to Fairfax Hospital, where she was pronounced dead shortly after 11 a.m. on Thursday, police said.
