A 40-year-old businessman is being tested for the Ebola virus in Saudi Arabia after displaying symptoms of a serious tick-borne viral disease following a trip to Sierra Leone.
The Saudi Ministry of Health said the patient has been taken to an isolated ward at a hospital in Jeddah and is in a critical condition with suspected viral haemorrhagic fever.
The ministry said: "The source of his infection could be one of several viruses, including Ebola virus because of his recent travel to a country in which there is an active outbreak of the disease."
The ministry said while viral haemorrhagic fevers have been found in Saudi Arabia, there has never been a case of Ebola in the Kingdom. Initial tests for the Dengue virus proved negative.
