RICHMOND, Va. — Several hundred inmates and staff at the Richmond jail will be screened for tuberculosis after a prisoner was diagnosed with the disease.

The jail was briefly locked down Thursday after VCU Medical Center notified the facility’s medical staff about the diagnosis.

Sheriff’s Maj. Jerry Baldwin tells The Richmond Times-Dispatch that the lockdown was a precautionary measure. He says the male inmate arrived at the jail on June 21 and was taken to the hospital on July 6.

Dr. Danny Avula with the Richmond City Health District says inmates and staff who may have had close contact with the prisoner will be screened for TB beginning next week.

Avula says 200 to 300 people will be screened, based on a preliminary list from the jail.
