A US citizen is being tested for the Ebola virus in Ghana, which has had no confirmed cases of the virus in the current West African outbreak.
The man has been quarantined at the private Nyaho Clinic in the capital, Accra, health officials say.
The virus has so far killed more than 460 people since it broke out in Guinea in February and spread to neighbouring Liberia and Sierra Leone.
It is the world’s deadliest outbreak to date and there is no cure for Ebola.
The US embassy in Accra said it had been informed that a US citizen was being tested but would not give any more details, Reuters news agency reports.
The man was believed to have visited Guinea and Sierra Leone in recent weeks.
Ghana’s health ministry said it had put in place “precautionary measures” and people should stay calm.
Staff at the clinic had also been quarantined and provided with protective clothing, it added in a statement.
