The World Health Organization(WHO) warned Friday that the Ebola situation was still "extremely alarming" while Sierra Leone lifted lifted crippling nationwide restrictions on movement put in place at the height of the Ebola crisis. The UN agency said the progress made so far could be rapidly undone if a funding gap remained. WHO number two Bruce Aylward said: "It's still an incredibly dangerous situation" and "extremely alarming, despite a significant fall in new cases in west Africa". The World Health Organization said in its latest update that 8,626 people had died as of January 18, among a cumulative total of 21,689 cases. Meanwhile, President Ernest Bai Koroma said in an address to the nation "Restrictions on movement will be eased to support economic activity. As such, there will no longer be any district or chiefdom level restrictions on movement," late Thursday. Koroma pointed to a "steady downward trend" in new cases in recent weeks, adding that "victory is in sight" but cautioning against complacency. The president said the travel bans would be removed from Friday and restrictions will be eased on Saturday trading hours in the hard-hit Western Area, which includes the capital Freetown. Koroma stressed however that the crisis would not be over until all three countries had seen no new cases for 42 days. He vowed that anti-Ebola measures such as a ban on washing bodies of victims of the highly infectious virus would remain in place. "Our records show that this is now the greatest threat to our victory over the disease," he said. "Law enforcement agencies and chiefs are under instruction to ensure that the full force of the law is brought to bear on those who touch or wash dead bodies." He added that while victory over the epidemic was in sight, "we must not relent, we must continue to soldier on". Sierra Leone is targeting zero new cases by March 31 of the deadly tropical fever that has killed around 9,000 west Africans over the past year, according to official data, although the real toll is thought to be significantly higher. The figure for Sierra Leone was 117 last week against 184 the week before, the WHO said, but added that the west of the country remained a problem area. The move marks huge progress in a crisis which has seen commerce all but grind to a halt, with travel restrictions hitting the rural communities particularly hard and sparking warnings of a looming food crisis.
