Africa's Ebola epidemic has not run its course and around 30 people are still getting infected each week, the UN's special envoy for the disease has said.
The worst recorded outbreak of the virus has killed more than 11,000 people across West Africa since late 2013, but had abated in recent months. A new flare-up in Liberia is seen as a setback in the fight against it.
"The battle can be won, but it requires sustained effort, very careful negotiation with communities and perfection in follow-up of everybody who has been a contact," David Nabarro told a media briefing in Cape Town.
He said under normal circumstances, an infection rate of 30 people a week would be considered "a major, major outbreak".
"Probably about one third of these people are not coming from the contact list, which means they are surprise cases, and that's a big worry," Mr Nabarro earlier told a conference organised by the World Health Organization.
Infection rates are down from the peak of the crisis. But Liberia reported a 17-year-old boy tested positive for the virus on June 30 - almost two months after the country was declared free of Ebola.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
