Why does Ebola keep coming back? Image copyright Getty Images The Ebola virus has reared its head again, this time in the Democratic Republic of Congo. While it is impossible to predict exactly where and when the next outbreak will occur, we now know much more about how to prevent a crisis.
The news of an Ebola outbreak in the town of Bikoro in north-west DRC instantly brings to mind the horror of the epidemic that took 11,000 lives and infected 28,000 people in West Africa between 2014 and 2016.
It is a nightmare no-one wants to relive - or should have to.
Since 4 April in the DRC, there have been more than 30 possible cases - involving 18 deaths - although only two incidents have so far been confirmed as Ebola.
So why does Ebola keep coming back and what work is being done to prevent a repeat of the tragedy in West Africa?
Out of controlEbola can spread rapidly, through contact with even small amounts of bodily fluid of those infected. Its early flu-like symptoms are not always obv..

Mr Johnson paid tribute to the DRC authorities and the Congolese Institute for Nature Conservation for their "tireless help".

South Africa direct rule for North West province Media playback is unsupported on your device Media captionRubber bullets were fired when police clashed with protesters in April South Africa has taken over direct administration of North West province where corruption allegations have led to violent protests.
There have also been calls for the regional premier to resign.
The decision to intervene was taken by President Cyril Ramaphosa, who has made the fight against corruption a priority.
Last month, he cut short his attendance at a Commonwealth summit in London to return home and deal with the crisis.
Ramaphosa: union leader, mine boss, president Zuma's fall a chance to take moral leadership in Africa The province's regional premier, Supra Mahumapelo - a political ally of former President Jacob Zuma - has refused to step down but went on leave.
His administration has been accused of corruption and the misuse of state funds - accusations he denies.

Icebergs and empty pools: Five things Cape Town's Day Zero taught us Image copyright AFP Image caption Despite being surrounded by water, Cape Town found itself at risk of running out of water When Cape Town revealed it was fast hurtling towards the moment it would become the first city on earth to run out of water earlier this year, it caught the world's attention.
Initial predictions said the taps in this South African city of four million people should have run dry by April.
But despite the odds appearing stacked against it, the dams never fell to 13.5% - the level needed to reach "Day Zero", which has now been pushed back to next year at the earliest.
The rains have finally arrived, and Cape Town appears to pulled itself back from the brink - for now.
So, what lessons have been learned?
Icebergs could be the answerAt times like this, it is probably always worth thinking outside the box.
But when Nick Sloane - a South African salvage captain known for righting the Costa ..
The couple who care for stricken dogs in an Indian beach town Image copyright Street Dog Watch Image caption Family and friends might be thousands of miles away, but there's no shortage of company During a 10-year exile in India, a British couple have spent £300,000 of their own money to help stricken dogs in a beach town. Why?
It was supposed to be a trip to see some of the world after taking early retirement.
After spending some time in Gran Canaria, Mary and Steve Muscroft booked a two-week package holiday to Kovalam in Kerala, south India.
They did not get on their return flight.
Instead, they stayed to look after two dogs that had captured their hearts.
Ten years on and they now have almost 100 dogs, run an animal clinic with three staff and have set up Street Dog Watch Association - an organisation that rescues stricken dogs and feeds, vaccinates and sterilises the area's strays.
