Francis Keteh, Deputy Incident Management System Leader, said in Mornovia that all the five Ebola patients were from Liberia’s north-central Margibi County.
He said that they include a 17-year-old boy whose death on June 28 made Liberia lose the Ebola-free status the World Health Organisation (WHO) had granted it in early May.
Keteh said that an additional seven suspected cases, 11 high risk cases and 42 low risk cases – who had all come into contact with the 17-year-old while he was ill – are currently being monitored at a treatment centre.
Neighbouring Guinea and Sierra Leone have not yet been able to stop transmissions of the virus that causes a deadly haemorrhagic fever.
According to WHO, about 27,600 people have been infected and more than 11,200 have died from Ebola in the three West African countries since December 2013.
