Doctors are still unsure what exactly killed two brothers in the Olivedale clinic in Johannesburg on Tuesday. The siblings, who died within 24 hours of each other, had not been out of the country recently, although they had been in contact with wildlife. Doctors suspect it is haemorrhagic fever, but all tests have come back negative so far. More tests are being conducted by the National Institute of Communicable Diseases. There was a brief scare on Monday when two nurses at the clinic suddenly developed a high fever, but doctors say that their symptoms are not the same as those of the deceased, so they probably don't have whatever killed the two brothers.
