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.

John Major's double warning for Theresa May

The former Tory Prime Minister broke his silence with a very loud rebuke. 

A month after the Prime Minister stood in Chatham House to set out plans for free trading, independent Britain, her predecessor John Major took the floor to puncture what he called "cheap rhetoric".

Standing to attention like a weather forecaster, the former Tory Prime Minister warned of political gales ahead that could break up the union, rattle Brexit negotiations and rot the bonds of trust between politicians and the public even further.

Major said that as he had been on the losing side of the referendum, he had kept silent since June:

“This evening I don't wish to argue that the European Union is perfect, plainly it isn't. Nor do I deny the economy has been more tranquil than expected since the decision to leave was taken. 

“But I do observe that we haven't yet left the European Union. And I watch with growing concern  that the British people have been led to expect a future that seems to be unreal and over-optimistic.”

A seasoned EU negotiator himself, he warned that achieving a trade deal within two years after triggering Article 50 was highly unlikely. Meanwhile, in foreign policy, a UK that abandoned the EU would have to become more dependent on an unpalatable Trumpian United States.

Like Tony Blair, another previous Prime Minister turned Brexit commentator, Major reminded the current occupant of No.10 that 48 per cent of the country voted Remain, and that opinion might “evolve” as the reality of Brexit became clear.

Unlike Blair, he did not call for a second referendum, stressing instead the role of Parliament. But neither did he rule it out.

That was the first warning. 

But it may be Major's second warning that turns out to be the most prescient. Major praised Theresa May's social policy, which he likened to his dream of a “classless society”. He focused his ire instead on those Brexiteers whose promises “are inflated beyond any reasonable expectation of delivery”. 

The Prime Minister understood this, he claimed, but at some point in the Brexit negotiations she will have to confront those who wish for total disengagement from Europe.

“Although today they be allies of the Prime Minister, the risk is tomorrow they may not,” he warned.

For these Brexiteers, the outcome of the Article 50 negotiations did not matter, he suggested, because they were already ideologically committed to an uncompromising version of free trade:

“Some of the most committed Brexit supporters wish to have a clean break and trade only under World Trade Organisation rules. This would include tariffs on goods with nothing to help services. This would not be a panacea for the UK  - it would be the worst possible outcome. 

“But to those who wish to see us go back to a deregulated low cost enterprise economy, it is an attractive option, and wholly consistent with their philosophy.”

There was, he argued, a choice to be made about the foundations of the economic model: “We cannot move to a radical enterprise economy without moving away from a welfare state. 

“Such a direction of policy, once understood by the public, would never command support.”

Major's view of Brexit seems to be a slow-motion car crash, but one where zealous free marketeers like Daniel Hannan are screaming “faster, faster”, on speaker phone. At the end of the day, it is the mainstream Tory party that will bear the brunt of the collision. 

Asked at the end of his speech whether he, like Margaret Thatcher during his premiership, was being a backseat driver, he cracked a smile. 

“I would have been very happy for Margaret to make one speech every eight months,” he said. As for today? No doubt Theresa May will be pleased to hear he is planning another speech on Scotland soon.
