They said the number of Ebola cases was declining in Sierra Leone and there was hope that the disease will soon be contained.
On their arrival in Sierra Leone, several Ebola cases were reported every week but when they left the country, the numbers dropped to three to no cases reported per week.
Initially, a group of healthcare professionals, comprising a medical doctor and professional nurses left to Sierra Leone on 23 January and returned to South Africa on 22 March.
After they completed their 21 days quarantine at home, where they were monitored daily, they made time to speak to media in Johannesburg on Thursday about their experience.
They all returned without having contracted the disease and also helped to reduce the number of Ebola cases in Sierra Leone.
