Two people who were initially suspected of having contracted the recently identified arena virus may be discharged from hospital on Wednesday, Morningside Medi-Clinic said.

"They are not believed to have contracted the virus and might be discharged today," said spokesperson Melinda Pelser.

The pair was admitted at Johannesburg's Morningside Medi-Clinic last week after there was a "discrepancy" in their temperatures.

Pelser said a nurse who did contract the virus remained in a stable condition.

Meanwhile, a radiographer has reportedly been admitted to Durban's St Augustines Hospital after displaying symptoms similar to those of the arena virus.

The radiographer had come into contact with the virus carriers while working at Morningside clinic, the Mercury newspaper reported on Wednesday.

However, it said "early indications" were that she did not have the virus.

A tour operator from Zambia, the paramedic who accompanied her to South Africa for treatment, and a health worker who came into contact with her, have died since 14 September.

Pelser said a task team of medical experts had for a second time endorsed the infection control procedures at their hospital.

She said 91 people who had been in contact with those who contracted the disease were being monitored at their homes.

The monitoring exercise would continue for 21 days from the person's last close contact with an infected person.
