Thermal scanners, which detect high temperatures among passengers, have been installed at O R Tambo Airport in Johannesburg and affected travellers, when identified, were quarantined and assessed at medical facilities at the airport, the airline's country manager Sajid Khan said in a statement.
He said regular fumigation and disinfection of South African Airways' aircraft were also being carried out.
"The department is working in close coordination with key organisations like the World Health Organisation and the United States Centres for Disease Control and Prevention, among others," Khan said.
Apart from heightened surveillance by Port Health officials for travellers with EVD signs and symptoms, he said, "All foreign nationals who test positive and all citizens of affected nations were being denied entry in South Africa."
