"The woman is in isolation and there are no other cases of the fever at the clinic at this time," Mediclinic Vergelen regional marketing manager Nadia Padayachi said.
The 39-year-old contracted the fever from a multi-coloured tick. She was in a serious but stable condition after she was admitted to the hospital over a week ago.
People with Congo fever suffer from flu-like symptoms and haemorrhaging. According to the World Health Organisation Crimean-Congo haemorrhagic fever is primarily transmitted to people from ticks and livestock animals.
Human-to-human transmission can occur from close contact with the blood, secretions, organs, or other bodily fluids of infected persons. There is no vaccine available for either people or animals.
