The Guinean government has set up a medical checkpoint near the country’s border with Sierra Leone in an attempt to stop the spread of Ebola.
People are being stopped and tested for the virus, which has killed almost 2,100 people in West Africa this year.
The scale of the outbreak has led the World Health Organisation to order an acceleration of normal drug development processes in order to find a successful vaccine or therapy for Ebola.
Countries affected by the outbreak are struggling to cope with the crisis.
Sierra Leone, which has witnessed almost 500 deaths, announced a four-day nationwide lockdown would take place later this month.
