Ghana is treating a suspected case of the deadly Ebola virus, the health ministry said.
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 vaccine or cure for Ebola.
The ministry said that it had put in place “precautionary measures” and that people should stay calm.
The case was recorded at the Nyaho Clinic in the capital, Accra, the health ministry said in a statement.
The patient and staff at the clinic have been quarantined and provided with protective clothing, it said.
The clinic was awaiting the results of blood tests to see whether the patient really had Ebola, the statement said.
“We will like to assure the general public that we have everything under control,” Tony Goodman, the health ministry’s public relations officer, said.
In April, Ghana’s health authorities said a girl suspected to have Ebola had tested negative.
Ebola spreads through contact with an infected person’s bodily fluids and kills up to 90% of those infected.
The health ministers of 11 West African states met in Accra last week promising to work more closely together to combat the outbreak.
So far, 759 people have been infected with the virus in Guinea, Liberia and Sierra Leone.
Most of the 467 deaths have been centred in the southern Guekedou region of Guinea, where the outbreak was first reported.
But health officials say the region’s porous borders have allowed infected people to carry the disease into other countries.
