Weeks after Sierra Leone was declared Ebola-free by the World Health Organisation (WHO), two new cases have been recorded in the country.

According to health officials, more cases may emerge as the two people who tested positive to the virus lived in a densely populated slum.

However, Sierra Leone's National Ebola Response Centre said there is great concern because all Ebola quarantine facilities in Freetown has been closed.

The West African is just recovering from the deadliest Ebola outbreak in history, which has killed over 11,000 since December 2013.
