The total number of confirmed Covid-19 cases in the Department of Correctional Services (DCS) stood at 605 on Monday, with 34 new cases reported since Sunday.
The department confirmed that 186 officials and 419 inmates had been infected. Recoveries are currently standing at 118.
The Western Cape and Eastern Cape are receiving heightened surveillance owing to a high number of cases, department spokesperson Singabakho Nxumalo said.
"This can also be explained by [Monday's] confirmation of an increment of 24 cases of inmates in the Western Cape.
"Healthcare officials continue to render a tremendous service as recoveries are recorded on a regular basis. Therefore, it remains critical that prevention measures do work in our correctional centres in order to contain infections and drive down active cases," Nxumalo said.
The Eastern Cape has the most infections at 416 - 55 officials and 361 inmates. The province has recorded 71 recoveries and two deaths.
The Western Cape has 165 infections - 116 officials and 49 inmates. The province has recorded 44 recoveries and two deaths.
