Two Johannesburg brothers were admitted to Olivedale Clinic because of a mystery illness. Both of them lost their lives. One brother died on Saturday and the other one passed away on Sunday night, exactly 24 hours after the former’s death.

Hospital officials have no clue of their mysterious death. Martina Nicholson, who is the Spokesperson of the hospital, said the case will be investigated properly by the National Institute for Communicable Diseases.

She further added that the result of the cause of death is slated to come up in the coming week.

It is said that the brothers didn’t go outside the country, but were in constant touch with flora and fauna.

The different tests that were conducted on them proved negative, but it was assumed that they might be suffering from hemorrhagic fever.

Two nurses who were in close proximity with the brothers were also thoroughly checked, but were found to be ok.

Hospital authorities have commiserated with the family members and urged people to respect their privacy.

It is worth noting that two years ago at least three people died, when they came in contact with the arena virus strain that spread quickly from the Morningside Clinic in Sandton.

The hospital is taking all the necessary precautionary measures and so far nobody is in quarantine and no more cases have been registered as well.
