Pretoria — The South African Department of Health says it is on high alert following the reported outbreak of the Ebola virus in the Democratic Republic of Congo (DRC).
On Friday, 12 May, the World Health Organisation (WHO) announced that nine suspected cases and three deaths of persons with Ebola virus disease (EVD) were reported from a remote forested area in the Likati Health Zone, Bas Uele Province in the north of the DRC, bordering Central African Republic.
"There is a low risk of transmission to South Africa. However, South African Emergency Departments and clinicians are advised to be on the alert for cases of fever and/or haemorrhagic symptoms amongst returning travellers from the area," the Department of Health said on Wednesday.
South African Port Health authorities have been informed and continue to screen persons, who enter via airports, for fever. However, no travel restrictions are in place.
As of 20 May, a total of 37 suspected EVD cases and four deaths have been reported, giving a case fatality rate of 11%. The reported cases are from five health areas, namely Nambwa (12 cases and three deaths), Muma (four cases and no deaths), Ngayi (16 cases and one death), Azande (three cases and no deaths), and Ngabatala (two cases and no deaths).
No healthcare workers have been affected to date. The majority of the cases presented with fever, vomiting, bloody diarrhoea and other bleeding symptoms and signs. The outbreak currently remains confined to Likati Health Zone.
The DRC Ministry of Health, World Health Organisation and various partners are working closely to rapidly control the outbreak through strengthened epidemiological surveillance, and implementation of a comprehensive logistics plan including the deployment of teams comprising experts in epidemiology, clinical management, social mobilisation and risk communication.
This is the eighth Ebola virus outbreak in the DRC since 1976. The last outbreak occurred in 2014 with 66 cases and 49 deaths.
Ebola virus is transmitted following direct contact with persons infected with the virus - through contaminated body fluids including blood, stool, urine, saliva and semen, or with an environment contaminated with body fluids.
Symptoms develop eight to 10 days after contact and include fever, weakness, myalgia, headache, sore throat, abdominal pain, rash and bleeding from mucous membranes. Treatment is supportive. Rapid implementation of infection control measures, as soon as the disease is suspected, is essential.
