A British national living in Sierra Leone has tested positive for Ebola, the Department of Health has said according to a BBC report.
It is the first reported case of a Briton contracting the deadly virus during the recent outbreak.
The Department of Health (DoH) said the overall risk to those in the UK continued to be “very low”.
In a statement, the DoH said medical experts were “assessing the situation to ensure that appropriate care is delivered”.
Consular assistance is being provided, the statement added.
A decision will now have to be made over whether the patient should be flown back to the UK, said BBC Nigeria correspondent Will Ross.
Earlier this month, British Airways suspended flights to Sierra Leone and Liberia until at least the end of August.
The Foreign Office has said Britons should think carefully before travelling to Sierra Leone, Guinea or Liberia.
“General medical facilities throughout Sierra Leone are currently under severe strain due to the Ebola outbreak, and unable to provide the same standard of healthcare as in the UK,” current advice states.
“Dedicated healthcare facilities for Ebola are overwhelmed.”
Deputy chief medical officer Prof John Watson said: “The overall risk to the public in the UK continues to be very low.
“We have robust, well-developed and well-tested NHS systems for managing unusual infectious diseases when they arise, supported by a wide range of experts.”
No further details have been given about the British national who tested positive to the Ebola virus
