Ebola could devastate South Sudan if it spreads into the country from the neighbouring Democratic Republic of the Congo, experts have warned.
A family infected with the deadly virus recently managed to cross into Uganda, where two of them died, but health workers were able to stop them spreading it.
But it may be a ‘much graver’ story if people were to carry the illness into South Sudan, to the north-east, because the nation is poorer and in the grip of a civil war.
South Sudan is deemed to be the DRC’s ‘most vulnerable’ neighbour and has been on high alert for 10 months because people regularly cross the border.
Health officials have been tirelessly trying to contain the virus in the DRC, where 1,522 of the 2,265 people diagnosed with Ebola since August have died.
But numerous factors have made stopping the outbreak impossible so far, including local people not trusting health workers and militants attacking medical camps.

The outbreak in the DRC has been getting worse as it drags on, with half of the deaths it has caused happening since April.
The government in Uganda was praised for managing to stop Ebola spreading when three cases popped up there after a family crossed the border.
But Adrian Ouvry, a humanitarian advisor for the aid organisation Mercy Corps, said South Sudan is not prepared to give the same repsonse.
‘Sudan would struggle,’ he told MailOnline from Uganda. ‘The other countries at risk include Rwanda and Burundi. But of all of them, South Sudan is by the far most vulnerable.
‘Uganda has experience of Ebola many times before. They know how to manage it where countries like Sudan wouldn’t.
‘If there were to be a case to happen in south Sudan there would be more panic than Uganda as it’s far less resourced. It would be much graver if it was there.’
South Sudan is not completely unprepared, however, and has been taking regular measures to ready itself in case Ebola does spread there.
Ebola taskforces meet weekly, lab staff have been trained in how to safely handle samples for testing, more than two million people have been screened while entering the country and the public is being warned about Ebola’s dangers.
A vaccination programme is also underway there, and more than 2,000 health workers in the south of the country have had a jab to protect them.
Juliet Bedford from the Social Science for Humanitarian Action Platform said it was ‘lucky’ up until the point Ebola was confirmed in Uganda on June 11.
She said: ‘I think if it was South Sudan that had been reported it, we would be looking at a very different scenario.
‘Uganda has the means and more capacity on the ground to be able to deal with it quickly.
‘Less so the case in South Sudan. Here we are looking at a place where health structures are weak, like in the DRC.’
Borders between the countries are easy to pass through and are mostly reliant on screening people’s body temperatures to see whether they may have Ebola.
However, symptoms can take as long as three weeks to develop so this method isn’t foolproof.
And people may use informal crossing points to avoid screening, research has shown.

Official figures show half of the Ebola outbreak’s fatalities having occurred since April, with two-thirds of cases leading to death

Local people have a deep distrust of the governments and Western healthcare volunteers. It’s particularly a problem in rural areas where communication is difficult. Pictured, villagers are educated about Ebola symptoms and prevention in western Uganda

Ms Bedford said there are a huge amount of unofficial borders between the African countries where families are able to cross whenever they want.
‘There are national boundaries in place, but from a community perspective there is no physical border like you see marked on a map,’ she said.
‘It’s not like people in the UK going through France.
‘Some are known as smuggling or routes of trade where people cross daily for markets. In some other areas the border is just open.’
Another factor making it difficult to control the outbreak is the regular attacks from militants, who often target health workers or isolation camps.
Armed rebels in the DRC – some believed to be linked to Islamic State – are risking the lives of locals and aid workers and have successfully killed numerous people over the past year.
Doctors and nurses working in the region have even threatened to strike if their safety isn’t improved.
Dr Sterghios Moschos, an associate professor at Northumbria University, said the situation is similarly violent in South Sudan.
He said: ‘A lot of the local negativity that would have been established in the DRC would have bled over into similar groups in South Sudan.
‘Unfortunately South Sudan is a very poor country. It doesn’t help there are civil war problems and ongoing activities that are very lethal. As far as I know the security there is not good.’
Even innocent local people are making the response difficult because many have a deep distrust of the governments and Western healthcare volunteers.
This is a particular problem in rural areas where communication is difficult and people may be less educated and more susceptible to political or religious propaganda.
Dr Moschos said: ‘Typically in these situations, it’s never possible to penetrate the local environment easily to offer healthcare.
‘If, and hopefully not when, the outbreak reaches South Sudan, then the situation becomes more problematic for the NGOs and the people that go in and try and help.
‘Already it’s very difficult as they are subject to attack.’
Armed militiamen reportedly believe Ebola is a conspiracy against them and have repeatedly attacked health workers battling the epidemic.
Dr Moschos said we must learn from epidemic in 2014, which killed 11,000 people and ravaged West Africa.
The epidemic started in a remote part of New Guinea and quickly spread to Liberia and Sierra Leone because of porous borders, weak surveillance systems and poor public health infrastructure.
Remote villages in the jungle of Sierra Leone – much like those in South Sudan – were unapproachable for the government, Dr Moschos said.
Dr Moschos, who in 2014 developed a diagnostics test that could be taken into the rural areas with immediate results, said: ‘There was so much mistrust with local people in contact with the central government.
‘You also had the people literally in the jungle who were part of the separate movements, shall we call them, who basically didn’t want anything to do with central government. They were left to do their own thing.
‘But when Ebola reached them, people had to go in and help and it was a battle of trying to explain what was happening.
‘I can’t say for certain that that will be the case in South Sudan but there is a lot of separation going on.
‘A lot of myths are making the resolution of the situation extremely difficult – up to the point healthcare workers are being shot at.’

A family were returning to Uganda from DRC when they were stopped at the border. Suspected to have Ebola, they were supposed to be taken back to Beni. But six escaped and entered Uganda through a market. Ebola was confirmed in a five-year-old boy and his grandmother when they were taken to hospital in Kasese district

Authorities have vowed to step up border security in DRC and Uganda following the cross-border spread that occurred as the result of a family who may have exposed Ugandans to the viral disease.
The family had been at the burial of a relative in the DRC before they were stopped at a border while returning to Uganda,
More than one of them were showing symptoms of Ebola – which include vomiting, a fever and diarrhoea.
But the family escaped from authorities and crossed into Uganda through a market place at Mpondwe, a busy border post where many use dirt trails or footpaths.
A day later, the family rushed to hospital in the Kasese district where it was confirmed three – two young boys and their grandmother – had been struck with the killer virus. The three all died over the next few days.
It drove the World Health Organization to hold an emergency meeting on June 14, in which they concluded that the risk of spread to countries outside the DRC ‘remains low’.
A declaration of a Public Health Emergency of International Concern (PHEIC) was rejected for the third time because WHO said it would ’cause too much economic harm’.
The decision left experts disappointed because, they say, the response continues to be hampered by a lack of money.
Jeremy Farrar, director of the Wellcome Trust medical charity, said declaring an emergency would have raised levels of international political support ‘which has been lacking to date’.
When cases of Ebola were confirmed in Uganda last week, Mr Farrar said the epidemic was in ‘a truly frightening phase and shows no sign of stopping anytime soon’.
