Guinea govt says two people have died from Ebola

Test samples from the two patients "revealed the presence of the Ebola haemorrhagic fever virus", the government said in a statement, while officials feared further suspected cases.

"For now, we have two confirmed cases and three suspected cases," it added.

The cases are the first in Guinea since the country was declared Ebola free at the end of last year, and the UN health agency warned that a recurrence of the tropical disease -- which has claimed 11,300 lives since December 2013 -- remained a possibility.

Two cases of the virus were identified in Sierra Leone in early January, the first cases since November last year.

A 22-year-old women died while her aunt survived.

WHO declared that flare-up officially over on Thursday after no new cases were seen for 42 days -- the length of two Ebola incubation cycles.

The WHO refers to these isolated cases as "flare-ups" but maintains the original "chains of transmission" have been stopped in Guinea, Liberia and Sierra Leone.

"WHO continues to stress that Sierra Leone, as well as Liberia and Guinea, are still at risk of Ebola flare-ups, largely due to virus persistence in some survivors, and must remain on high alert and ready to respond," it said in a statement.

The health body's representative in Sierra Leone, Anders Nordstrom, said it was "critical that we remain prepared".

The virus can stay in semen for at least nine months after a patient has recovered, six months longer than previously thought.

Scientists are working to establish how long it can persist in other bodily fluids and tissues such as the spinal column and the eye, and for how long it could remain infectious.

"Until the virus is completely cleared from the survivor population -- and that may take the remainder of the year or more -- we have to anticipate and be prepared for additional small outbreaks," a WHO representative told AFP.

All five of the new cases in Guinea were from the town of Korokpara in the southern region of Nzerekore.

"The health authorities have taken the appropriate measures to contain the spread of the disease," the statement added.

The WHO confirmed Guinea's new cases on its Twitter account.

A source close to the local anti-Ebola coordination team told AFP that the two deceased patients were a married couple who had both shown symptoms of vomiting and diarrhoea.

"That attracted the attention of local people who alerted the health services in Nzerekore," he said on condition of anonymity.

Although the outbreak -- the worst on record -- has officially claimed more than 11,300 lives since it first began in Guinea, a significant number of deaths are believed to have gone unreported.

The epidemic was first reported to have spread to Sierra Leone in May 2014, when more than a dozen women contracted Ebola at the funeral of a healer who had been treating patients from Guinea.

At the peak of the outbreak that year, Sierra Leone and its neighbours Liberia and Guinea were reporting hundreds of new cases each week, with social order on the brink of collapse.

The WHO declared Guinea Ebola-free on December 29, followed by Liberia on January 14.
