The doctors were shot when heavily armed men burst into their residence at Letaba Hospital in Limpopo during a robbery early on Thursday.
The provincial health department said in a series of tweets that witnesses reported that five heavily armed men speaking in a foreign language had carried out the robbery.
Limpopo police spokesperson colonel Moatshe Ngoepe said the doctors were asleep when the group of men broke in. The robbers stole cellphones, televisions, laptops and cash.
Police also reported a robbery at the Lebowakgomo Hospital. They are investigating cases of attempted murder and house robbery.
