How Twitter could save your life

Inane chat about runny noses, or pandemic predictor?

Back in 2010 AMC set up co-ordinated “zombie attacks” in major cities around the world to promote its zombie thriller series The Walking Dead. Gaggles of blood-dripping “walkers” invaded trains and lurched around landmarks like Big Ben and The Prado Museum. Just one small scratch, or, worse, a desperate, flesh-eating bite, and you would become a zombie too – in the drama, of course.

AMC’s most popular programme now pulls in over 12 million viewers per episode and has nearly 1.5 million Twitter followers, each obsessed with the dramatic, but scarily plausible, scenario of a true life version of blockbuster films like Outbreak, Contagion or 28 Days later.

But as Twitter continually proves itself to be such an adept viral tool, the sheer number of users – which is 500 million and counting – flocking to its pages could make it a hefty ally in the fight to contain such an outbreak. Twitter, it seems, may not only be the best place to send a  meme like the walking dead  ‘viral’, but also the perfect platform for stopping a virus dead in its tracks.

Twitter users react to current events and tweets contain real-time information about their perspective and location. If Lori Grimes, for example, had been on Twitter, could word have spread faster than The Walking Dead’s zombie outbreak? And could Contagion’s MEV-1 virus have been prevented if Beth Emhoff had tweeted about her supposed cold symptoms?

These questions might read like science fiction, but Professor Simon Hay at the UK’s University of Oxford believes there is a “revolution occurring” in the amount of public health data that is available through social media, particularly from Twitter.

While scientists have traditionally used mapping techniques to track outbreaks, it is just 4 per cent of infectious diseases that have been effectively mapped. New technology is required to improve results and Twitter could provide the answer.

In fact, Twitter has already provided geo-positioned information to inform scientists about public health. A study from the University of Iowa proved that content embedded in Twitter feeds relating to the H1N1 flu outbreak in 2009 allowed the tracking of “rapidly-evolving public sentiment” and “actual disease activity”.

By using Twitter's streaming application programmer's interface (API), the study explored public sentiment from 29 April to 1 June 2009 by identifying 951,697 tweets out of 334,840,972 that matched specified search terms, such as flu, swine, influenza, H1N1 and illness.

The second phase selected 4,199,166 tweets – which conformed to certain guidelines, such as they had to be in English and originate from the US – from eight million influenza-related tweets that included relevant keywords sent between 1 October and 31 December 2009. The study found that these Twitter feeds actually predicted outbreaks one to two weeks in advance of traditional surveillance.

Scientists are currently struggling to map the current outbreak of the H7N9 avian influenza virus in China – which is considered by the World Health Organisation to be a “serious threat” (126 have been infected to date and 24 have died), despite it not spreading through people as yet – so why isn’t Twitter’s data stream being utilised?

Could it be due to the lack of Twitter users in China? According to a programmer (@ooof) on the South China Morning Post blog, the number of live active Twitter users could be as little as 18,000. If this number was more, would scientists have been better able to predict this very real threat to our society’s health?

As an online flu detector exists in the UK, which has been created by a team at the University of Bristol through identifying keywords from Twitter’s geo-located content, then couldn’t similar programs be used to identify and predict other, more serious, infections?

Twitter has come a long way since it launched, when it attracted intense criticism from naysayers questioning why they would want to tweet inane information about an erupting spot or runny nose. But, in the battle against pandemic outbreaks, it is ironically these kinds of observations that could empower Twitter to become a sophisticated tool and actually be more than just a social lifesaver in the future.

What are the consequences of Brexit for the refugee crisis?

Politicians neglected the refugee crisis whilst campaigning – but they shouldn't now concede to the darker undertones of the debate.

In the chaotic aftermath of Brexit, the refugee crisis seems like a distant memory. Yet not even a year has passed since the body of a young Syrian boy washed up on a Turkish beach, shocking the world.

When campaigning for the EU referendum began, politicians neglected the crisis. Not because the situation had ameliorated, but because the issue had become strategically toxic. Nigel Farage's infamous poster aside, the Leave side preferred scare stories about economic migrants rather than refugees; the Remain side because the refugee crisis, more than anything else since its inception, highlighted the fragility of the ideals that underpin the European Union.

Many of the main issues aired in the course of the referendum debate were related to the refugee crisis, regardless of how little it impacted on them in reality; immigration, strain on public services, national identity. The refugee crisis became a proxy issue; implied, but not addressed, for fear of detrimental impact in the polls.

However, in his repugnant posters (it should be stressed, nothing to do with Leave campaign itself), Nigel Farage made explicit what he thought posed the greatest threat to the UK. Rightly, the posters have been condemned by both sides of the referendum debate, but the underlying suspicion of refugees it reflects has concerned many organisations.Their concern has only been exacerbated by the result of the referendum. The spike in hate crime compounds their fears.

Paul Dillane, head of UKLGIG, a charity that supports LGBTI asylum seekers to the UK, expressed unease at the reaction of his clients: “The asylum seekers I work with do not understand the decision that has been made – they feel vulnerable, they feel unwelcome. Yes the law hasn’t changed, and if they’re at risk of persecution, they will be protected. But they don’t feel like that now.”

Despite the troubling situation, the result of the referendum changes little when it comes to refugee law. “Refugee policy is shaped in London, not in Brussels”, said Stephen Hale, Chief Executive of Refugees Action. “The decision about how well we support refugees in terms of integration is a matter for the UK, not Brussels. The number of Syrian refugees we choose to resettle is a matter for the UK, not Brussels.”

Although the law may not have changed, from a diplomatic or political perspective, the same cannot be said. This does have the power to negatively impact legislation. Post-Brexit reaction in France surrounding the Touquet Treaty typifies this.

The Touquet Treaty, reached between the UK and France in 2003, permits each country to carry out passport checks on the other countries’ soil. It is what, according to French politicians in Calais, has accelerated the growth of the "Jungle", which currently accommodates close to 5,000 refugees.

Because the agreement was signed outside the auspices of the European Union, Brexit does not affect its legal legitimacy. However, for France, EU membership was crucial to the nature of the agreement. Speaking earlier this year, Harlem Desir, French Secretary of State for European Affairs, said the Touquet Treaty is “a bilaterial agreement. So, there will be no blackmail, nor threat, but it’s true that we cooperate more easily in both being members of the EU.”

Natacha Bouchart, mayor of Calais and a long-time critic of the treaty, has been vocal in her demands for legislative change since the result. Speaking to French broadcaster BGM TV, she said: “The British must take on the consequences of their choice. We are in a strong position to push, to press this request for a review and we are asking the President to bring his weight to the issue.” Some have adopted the slogan of the Leave campaign, telling them to now “take back control of your borders.”

Modification of the Touquet Treaty was branded part of ‘Project Fear’ by the Leave campaign. Because of this, change – if indeed it does happen – needs to be handled carefully by both the British and French governments.

The reaction of Natacha Bouchart is already a worrying sign for refugees. Firstly, it perpetuates the toxic narrative that casts refugees as an inconvenience. And secondly, any souring of relations between the UK and France over Brexit and the Touquet Treaty only increases the likelihood of refugees being used as political bargaining chips in the broader EU crisis over Schengen.

A divided government and disintegrating opposition do little to aid the situation. Furthermore, come October, how likely is a Brexit Tory cabinet – governing off the back of a manifesto predicated on reducing immigration – to extend the support networks offered to refugees? Even before the referendum, Theresa May, a supporter of the Remain campaign, said that Britain should withdraw from the European Convention on Human Rights, replacing it with the more questionable Bill of Rights.

Uncertainty of any kind is the most immediate danger to refugees. “Everyone is talking about it,” said Clare Mosesly, founder of Care4Calais. “But opinions on the impact are divided, which is creating yet more uncertainty.” Refugees, unsure whether Brexit will lead to increased fortification of the border, are prone to take ever more dangerous risks to reach the UK. Even economic uncertainty, seemingly distinct from issues such as the refugee crisis or immigration, has a negative impact. “The thing that worries me about a fragile economy”, said Paul Dillane, “is that when a country’s economy suffers, minorities suffer as well. Tolerance and inclusivity are undermined.”

The government must stress that the welcoming principles and legislation Britain had prior to Brexit remain in place. Andrej Mahecic, from the UNHCR, said “we will continue to rely on the UK’s strong support for humanitarian responses to refugee crises. Our work with the government on the UK’s asylum system and refugee resettlement schemes continues.”

The will from NGOs is there. The political will is less assured. In the aftermath of Brexit, the government must not concede to the darker side of the referendum debate.
