LAGOS, Dhu-AlQa'dah 16, 1435, September 11, 2014, SPA -- Nigerian health authorities said on Thursday they were holding for Ebola testing a South African national in transit to her country because she was showing potential symptoms of the disease after working in Guinea and Sierra Leone, Reuters reported. The South African woman, whose identity was not revealed, flew in to Lagos airport from Morocco. She was being treated as a suspected case and was being taken to Lagos' Ebola treatment centre for tests to see whether she actually had the virus. The traveller, who lives in Cape Town, filled out a health questionnaire on her arrival at Lagos in which she acknowledged suffering from diarrhea and vomiting, both possible symptoms of the Ebola hemorrhagic virus. Around 2,300 people have died so far this year in the worst Ebola outbreak on record which has mostly affected Liberia, Sierra Leone and Guinea. It has also reached Nigeria and Senegal because of sick travellers "importing" the disease. Democratic Republic of Congo has a separate outbreak. --SPA 14:00 LOCAL TIME 11:00 GMT www.spa.gov.sa/w
