Death rides a bicycle: Why is riding a bike so often lethal?

Cyclists make 570,000 journeys each day in London – and every one of them could be their last.
“I’m determined to turn London into a cyclised city – a civilised city where people can ride their bikes safely and easily in a pleasant environment”
Boris Johnson, the Mayor of London, Cycling Revolution London, May 2010.
 
Close to my house in Lambeth in central London, there is a road junction where, once a week, I nearly die. The other day, while I was waiting to turn right to cycle up North Street, as the traffic on Wandsworth Road blasted towards me on the left and past me on the right, an HGV driver miscalculated his angle and aimed his lorry straight at me. There was no gap for me to escape into on either my left or my right. All I could think of doing was to stare at the windscreen of the lorry that was going to kill me and use mind control to make him shift his wheel or just hope that he was going to see me and do it of his own accord. It was all so fast – and I never saw my potential assassin – but one of these things happened and he adjusted his course. I shivered as he barrelled past.
 
The following day, I was at the same junction, waiting again to turn right. The lights had just changed to red, so I pushed down on my pedal to make my turn before the traffic moved against me. Suddenly, a boxy red Cadillac overtook a bus and was about to speed through the red light and kill me – but the driver at last saw me and managed to stop with a foot or two to spare. Shaking my fist and imprecating the sort of loud, meaningless sounds that come out of one’s mouth in these situations, I went up the hill in some kind of safety.
 
Having endured several experiences of this sort at this junction in the past, I have learned mostly to avoid this situation but sometimes – when the timing is off, the morning conspiring against me – it’s unavoidable. Usually I’d wait for the pedestrian green man to go on in all directions and then turn slowly, giving precedence to any pedestrians. This is one of the rules I ride by: if I’m breaking the Highway Code, I’m not going to impede, alarm or scatter pedestrians when they have the right of way. If, to avoid a greater evil, I happen to be temporarily on the pavement, then I will be courteous and apologetic as I make my progress. They have priority but my first imperative as a cyclist is to carry on living. 
 
My most recent near-death experience was, unusually, the result of the negligence of a taxi driver. Unfriendly and aggressive to cyclists as many of them are, they almost always allow us to live. They don’t like us, however, and will give us only a narrow margin of error and they often fail to indicate, as if to do so were somehow demeaning, or else they will put on their turning light as a sort of afterthought only once they’ve changed direction. That is what this one did, abruptly turning left on Charing Cross Road on to Shaftesbury Avenue, by which time I was already on his inside. I braked, jittered, avoided falling. He turned left, I chased after him. 
 
He was depositing passengers outside a hotel, which is where I spent some time haranguing him. Foolishly, I was bent on getting him to apologise, to admit that he had made a mistake, to acknowledge that he had turned without looking, that he had nearly killed me and that if I had died it would have been his fault. This was never going to happen: a matter of professional vanity as well as, probably, personal principle. “I’m not going to hold up London for a pushbike,” he said. I could see his point but he was not looking at mine. “You were behind me,” he said. “I was inside you,” I said. “Look,” he said, “there’s thousands of you.” 
 
This is where we got to. I tried and failed to make him see that there were not thousands of me, just one, with a wife and two children and others who would mourn my passing.

“The thing that makes cycling safe in London is when people have the confidence to do it in numbers. The more you can get on the roads, the safer it is going to be for everybody.”
                         Boris Johnson, after the death of a cyclist riding a “Boris bike” on Barclays Cycle Superhighway 2 on 5 July
 
Transport for London has estimated that there are 570,000 bicycle journeys in London every day, which is a rise of roughly 80 per cent in the past ten years. In central London nearly a quarter of the morning commuters are cyclists: in the rush hour, cycling is cheaper and quicker than any other means of transport. And anyone who cycled happily as a child never loses that sense of freedom that being on a bicycle brings. 
 
When I first started cycling again in London, about 20 years (and five stolen bikes) ago, it took about two weeks of terror for me to begin to forget just how physically exposed I was. You have to bracket off your vulnerability; otherwise, you wouldn’t be able to negotiate the dangers. This vulnerability rises back into consciousness only when you have, or witness, an accident or a near accident, or when you reach safety. 
 
The conditions cyclists endure perhaps account for some of the pious ferocity of the Lycra road warriors, some of whom are treating the city as their own racecourse. These are the ones who run every red light, mounting the pavement when the way ahead is blocked and continuing their journey with hardly any less speed, scattering pedestrians at zebra crossings as they pump away with their self-adored legs. They are protected by their sense of their own virtue – they are carbon-neutral, therefore their way is the better one. Car drivers are selfish, therefore cyclists can do what they like.
 
But even though they’re dangerous to themselves and to others, and give cyclists a bad reputation, they are the small minority. Most of us stop at red lights (I’m often grateful for the excuse) and would welcome police enforcement against those who don’t. Most of us have a code of courtesy to other road users. The ones who make the roads most dangerous are the drivers who consider it beneath them to indicate; parents in 4x4s, texting and tweeting with a screaming baby in the back on suburban school rat-runs; drivers who stop their cars in bicycle lanes; parked cars that suddenly have open doors . . . The list goes on. I have a particular antipathy to Audis, for example; but at the top of everyone’s list would be the HGVs.
 
***
“. . . these superhighways are central to the cycling revolution I’m determined to bring about. No longer will pedal power have to dance and dodge around petrol power – on these routes the bicycle will dominate and that will be clear to all others using them. That should transform the experience of cycling – boosting the safety and confidence of everyone using the routes and reinforcing my view that the bike is the best way to travel in this wonderful city of ours.”
Boris Johnson, 2009, on the launch of his Cycle Superhighways
 
Most cyclists who travel around central London will have seen the mayor on his bike, suited, trouser-clipped (more Philip Larkin than Bradley Wiggins), with the expression of someone who is expecting to be recognised but is really in rather a rush and can’t stop to chat. Boris Johnson has raised public awareness of cycling and made it easier to join in by implementing the scheme of socalled Boris bikes that are available for hire around the city. He has not succeeded in reducing the numbers of bicyclist deaths and severe injuries.
 
On 12 July, I was part of a “flashride” that was organised by the London Cycling Campaign to draw attention to the dangers of cycling in the capital. A week before, Philippine de Gerin-Ricard, a 20-year-old student from France, had become the first person in London to be killed on a “Boris bike” as she was cycling across Aldgate gyratory on Cycle Superhighway 2. She may have strayed out of her lane to avoid roadworks; but whatever the circumstances, the notional lines that separate cyclists from industrial traffic are not sufficient. This is the main road between the City and Canary Wharf, where the cyclists’ “superhighway” is a narrow stretch of blue, often impeded by parked cars, and into which traffic necessarily encroaches. She was the third cyclist to be killed by a lorry in the vicinity of CS2. As the victim’s mother said, none of us can “understand how they can put bicycles and motor vehicles so close together at this spot”. Her death was the second in London in a fortnight, after a hit-and-run by an Audi in Lewisham at the end of June. (I make a small apology for the focus on London in this piece: but this is where I live, and bicycle.)
 
***
“. . . as for my blue bike lanes . . . there is no ban on allowing your wheels to stray into them; they are there purely, as you know, they are there for indicative purposes . . .”
Boris Johnson, 22 July 2012, speaking on Sky News
 
We should give the mayor some due. Since he took office in 2008, London has become more attentive to cyclists. There are more dedicated bicycle lanes; the “Boris bikes” have put more cyclists on the roads; London has taken stuttering steps towards a cohesive bicycle-route plan. But since he’s been in office, 65 cyclists have died in the city. 
 
The road surfaces need improving – every day, I have to swerve into traffic to avoid potholes. We need separate bicycle lanes that are more than “indicative” lines of paint. London should follow the example of Paris, which has banned HGVs from the city between the hours of 8am and 8pm. There were no cycling deaths in Paris last year.
 
About 1,500 of us on the LCC’s “space4cycling” flashride milled around by the green opposite Tower Hill Docklands Light Railway station waiting for it to begin. There was conversation about accidents and near accidents, and the dangers of the superhighways. I was in a suit, my neighbour in Lycra. We compared the dangers on our regular routes. I asked him if he stopped at red lights on his commute from Bromley to Bishopsgate, and he said that he did. Only if there were clear sightlines to empty roads and no pedestrians would he sometimes go through. He talked about the arguments he’s had with motorists who say that if they pay a road tax so should cyclists: “The road tax was abolished! They pay an emissions tax.”
 
I didn’t have the opportunity to pursue this conversation, because I’d just caught sight of someone I thought I recognised, the sister-in-law of a very good friend of mine. I texted my friend to ask him if it was likely that Ann should be part of a cycling campaign, and he texted back that it was more than likely and would I call him. He was at King’s College Hospital, beside his 15-year-old son, who had had his pelvis broken that afternoon. Cycling home along the Wandsworth Road, he had been knocked off his bike by an HGV, whose driver had cut across to turn into a side road without looking or indicating. Guy had to be pulled out from under the lorry. The doctor attending him said: “Everyone has a little bit of luck in their lives and you’ve just had yours.” I don’t know how well this registered with Guy, who was vomiting at the time, in reaction to the morphine he was being given for the pain.
 
The marshals invited us to make some noise, and we rang our bells and there was some chanting of “Blue paint is not enough!” and then we slowly set off. The route took us to Aldgate and to the site of Philippine de Gerin-Ricard’s death, where a wreath was laid and we stopped for a minute’s silence.
 
The ride itself took about 20 minutes or so and that part of London stopped for us, whether the taxi drivers liked it or not; but the expressions on the faces of drivers waiting behind police marshals for us to go through were curious and sympathetic rather than annoyed at being made to wait. At the end, we gathered in Altab Ali Park, off the Whitechapel Road, and Guy’s aunt addressed us, calling on the mayor to take action and Transport for London to make the city safer for cyclists, and asking us, without yet knowing that her nephew had very nearly joined them, to remember the recently dead.
 
And then we cycled away from the park, most of us heading west into town, along narrow blue strips on potholed arterial roads, towards homes and workplaces and hospitals.

A century ago, the Spanish flu killed 100 million people. Is a new pandemic on the way?

Our leaders need to act like the outbreak has already started – because for all we know it may have.

It is hard not to have a sneaking envy of the virus. As complex creatures, we are distracted by myriad demands on our attention; we will never know the dead-eyed focus of the viral world. It is akin to the psychopath: a cold, purposeful drive to achieve its own agenda, coupled with the skills and resourcefulness to succeed. In a world threatened by nuclear war and devastating climate change, it may actually be the virus that we should fear most.

This is the centenary year of the Spanish flu outbreak, when a virus killed between 50 and 100 million people in a matter of months. The devastation was worldwide; it is only known as Spanish flu because Spain, neutral in the ongoing hostilities of World War One, was the only country without press restrictions. Across Europe, people assumed their own outbreaks originated in the only place reporting on the disaster.

A number of authors have lined up with a kind of grim celebration of influenza’s annus mirabilis. As well as chronicling the fatal reach of this organism, they all offer a warning about a follow-up pandemic that is overdue – and for which, it seems, we are largely unprepared. “Somewhere out there a dangerous virus is boiling up in the bloodstream of a bird, bat, monkey, or pig, preparing to jump to a human being,” says Jonathan Quick in The End of Epidemics. “It has the potential to wipe out millions of us, including my family and yours, over a matter of weeks or months.”

If that seems a little shlocky, you should know that Quick is no quack. He is a former director at the WHO, the current chair of the Global Health Council and a faculty member at Harvard Medical School. The book’s blurb includes endorsements from the director of the London School of Hygiene and Tropical Medicine, the president of Médicins Sans Frontières, and the president of the Rockefeller Foundation.

The numbers Quick serves up are stupefying. Bill Gates, for instance, has said it is more likely than not that he will live to see a viral outbreak kill over 10 million people in a year. In Gates’s nightmare scenario, outlined by computer simulations created with disease-modelling experts, 33 million people die within 200 days of the first human infection. The potential for exponential spread means a death toll of 300 million is possible in the first year. “We would be in a world where scrappy, ravaged survivors struggle for life in a zombie-movie wasteland,” Quick tells us in his informed, cogent and – honestly – frightening book.

If you can’t imagine what that is like, you could try asking the Yupik people of Alaska, who were devastated by the 1918 Spanish flu. You might not get an answer, however, because they remain traumatised, and have made a pact not to speak about the pandemic that shattered their ancient culture.  (A pandemic is a disease that spreads across continents; an epidemic is usually contained within a country or continent.)They aren’t the only long-term sufferers. The Vanuatu archipelago suffered 90 per cent mortality and 20 of its local languages went extinct. Those in the womb in 1918 were also affected. A baby born in 1919 “was less likely to graduate and earn a reasonable wage, and more likely to go to prison, claim disability benefit, and suffer from heart disease,” reports Laura Spinney in Pale Rider.

Such arresting snippets of the flu’s legacy abound in Spinney’s thoughtful, coherent take on the 1918 outbreak. The book’s subtitle suggests that the Spanish flu changed the world, and Spinney certainly backs this up. Societies broke down and had to be rebuilt; recovering populations were reinvigorated by the simple calculus of Darwin’s “survival of the fittest”; public health provisions were first imagined and then brought into reality; artists and writers responded to a new global mood by establishing new movements.

Not every outcome could be spun as a positive. Scientists, for instance, were humiliated by their inability to halt the flu’s progress, creating an opportunity for quack medicines to arise and establish themselves. Some of our greatest writers lived through the trauma, but could never bring themselves to discuss it in their stories. Virginia Woolf noted that it was “strange indeed that illness has not taken its place with love and battle and jealousy among the prime themes of literature”.

Spinney’s background as a science writer shines through: her handling of the workings of the flu is detailed and deft. She brings both the influenza A virus (the only type responsible for pandemics) and the human immune system to life, laying out the biochemical processes that kill and cure with clarity and care. She exposes the chilling roots of often-used but seldom-explained viral names such as “H1N1” (Spanish flu) or “H5N1” (bird flu). H is for haemagglutinin, the lollipop-shaped appendage that allows a virus to break into a cell and take over the means of production. N is for neuraminidase, the “glass-cutter” structure that allows replicated viruses to break out again and unleash hell upon the host. So far, we know of 18 H’s and 11 N’s and they all have ever-evolving sub-types that make a long-lasting general vaccine against the flu an elusive dream: “Every flu pandemic of the 20th century was triggered by the emergence of a new H in influenza A,” says Spinney.

For all her technical expertise, Spinney has a light touch and a keen eye for the comic. She relates how a ferret sneezing in the face of a British researcher in 1933 exposed influenza’s ability to travel between biological species, for instance. She also excels with the bigger picture, detailing the century of scientific detective work that has allowed us to piece together the genetic elements of the 1918 virus and gain insights into its creation. It seems to have jumped to humans on a farm in Kansas, via domestic and wild birds indigenous to North America. There may also have been some ingredients from pigs, too, but that’s not settled.

Spinney’s afterword questions whether our collective memory for such events ever reflects the truth of the moment. “When the story of the Spanish flu was told, it was told by those who got off most lightly: the white and well off,” she tells us. “With very few exceptions, the ones who bore the brunt of it, those living in ghettoes or at the rim, have yet to tell their tale. Some, such as the minorities whose languages died with them, never will.”

That said, Catharine Arnold has done a remarkable job of relating the tales of a diverse set of sufferers, crafting an arresting and intimate narrative of the 1918 pandemic. She pulls the accounts of hundreds of victims into a gripping tale that swoops down into the grisly detail, then soars up to give a broad view over the landscape of this calamitous moment in human history.

Arnold’s remembrances come from the unknown and from celebrities. A Margery Porter from south London emphasised that “we just couldn’t stand up. Your legs actually gave way, I can’t exaggerate that too much.” John Steinbeck described the experience of infection as almost spiritual. “I went down and down,” he said, “until the wingtips of angels brushed my eyes.”

The reality was, inevitably, less poetic. A local surgeon removed one of Steinbeck’s ribs so that he could gain access to the author’s infected lung. Most victims’ bodies turned blue-black as they died. Healthcare workers reported appalling scenes, with delirious patients suffering horrific nosebleeds. “Sometimes the blood would just shoot across the room,” a navy nurse recalled. If their lungs punctured, the patients’ bodies would fill with air. “You would feel somebody and he would be bubbles… When their lungs collapsed, air was trapped beneath their skin. As we rolled the dead in winding sheets, their bodies crackled – an awful crackling noise with sounded like Rice Krispies when you pour milk over them.”

The killer in 1918 was often not the flu virus itself but the “cytokine storm” of an immune system overreacting to the infection. Strong, fit young people, with their efficient immune systems, were thus particularly at risk, their bodies effectively shutting themselves down. Then there were the ravages of opportunistic bacteria that would lodge in the devastated tissue, causing pneumonia and other fatal complications. Arnold paints a grim but vivid picture of exhausted gravediggers and opportunistic funeral directors cannily upping their prices. The morgues were overflowing, and morticians worked day and night. In the end, mass graves were the only answer for the poverty-stricken workers attempting to bury their loved ones before they, too, succumbed.

No one was spared from grief or suffering at the hands of the “Spanish Lady”, as the flu came to be known. Louis Brownlow, the city commissioner for Washington DC, reported nursing his stricken wife while answering telephone calls from desperate citizens. One woman called to say that of the three girls she shared a room with, two had died, and the third was on her way out. Brownlow sent a police officer to the house. A few hours later, the sergeant reported back from the scene: “Four girls dead.”

Some of the other stories Arnold has unearthed are equally heartbreaking. A Brooklyn boy called Michael Wind wrote of the moment his mother died after less than a day of being ill. He and his five siblings were at her bedside, as was their father, “head in hands, sobbing bitterly”. The following morning, knowing that he was soon to die too, their father took the three youngest children to the orphanage.

Arnold writes beautifully, and starkly, of the tragedy that unfolded in the autumn months of 1918: “the Spanish Lady played out her death march, killing without compunction. She did not discriminate between statesmen, painters, soldiers, poets, writers or brides.” She chronicles the Lady’s path from the United States and Canada through Europe, Africa and Asia, culminating in New Zealand’s “Black November”. The book is utterly absorbing. But how do we respond to its horrors and tragedies? What are we to do with our collective memories of such visceral, world-shattering events? Learn from them – and fast, argues Jonathan Quick.

Unlike Arnold and Spinney, Quick is not content to be a chronicler or a bystander. He is, he says, both terrified at the looming disaster and furious at the lack of high-level reaction to its threat. He is determined to create a movement that will instigate change, mimicking the way activists forced change from governments paralysed by, and pharmaceutical companies profiteering from, the Aids pandemic. Quick has channelled his fury: The End of Epidemics is, at heart, a call to arms against influenza, Ebola, Zika and the many other threats before us.

 

So what are we to do? First, our leaders need to act like the outbreak has already started – because for all we know it may have. We must strengthen our public health systems, and create robust agencies and NGOs ready to monitor and deal with the threat. We must educate citizens and implement surveillance, prevention and response mechanisms, while fighting misinformation and scaremongering. Governments must step up (and fund) research.

We can’t develop a vaccine until the threat is manifest, but we can prepare technology for fast large-scale production. We can also invest in methods of early diagnoses and virus identification. Invest $1 per person per year for 20 years and the threat will be largely neutralised, Quick suggests. Finally – and most importantly – there is an urgent need to create grass-roots support for these measures: citizen groups and other organisations that will hold their leaders to account and prevent death on a scale that no one alive has ever experienced. Is this achievable? Traumatised readers of Quick’s book will be left hoping that it is.

For all the advances of the last century, there are many unknowns. Scientists don’t know, for instance, which microbe will bring the next pandemic, where it will come from, or whether it will be transmitted through the air, by touch, through body fluids or through a combination of routes.

While there is considerable attention focused on communities in West Africa, East Asia or South America as the most likely source of the next outbreak, it’s worth remembering that most scientists now believe the 1918 influenza outbreak began on a farm in Kansas. Quick suggests the
next pandemic might have a similar geographical origin, thanks to the industrialised livestock facilities beloved by American food giants.

Viruses naturally mutate and evolve rapidly, taking up stray bits of genetic material wherever they can be found. But it’s the various flu strains that live inside animals that bring sleepless nights to those in the know. They can exist inside a pig, bat or chicken without provoking symptoms, but prove devastating if (when) they make the jump to humans. As more and more humans live in close proximity to domesticated animals, encroach on the territories inhabited by wild animals, and grow their food on unprecedented scales, our chance of an uncontrollable epidemic increase.

The meat factories known as “Concentrated Animal Feeding Operations” (CAFOs) are particularly problematic. They provide cheap meat, poultry, dairy and
eggs from animals kept in what Quick terms “concentration camp conditions”, simultaneously creating the perfect breeding ground for new and dangerous pathogens. Pigs, he points out, eat almost everything, so their guts are the perfect mixing bowls for a new and deadly influenza strain. “CAFOs were the birthplace of swine flu, and they could very likely be the birthplace of the next killer pandemic,” Quick warns.

There are other possibilities, though – bioterror, for instance. Bill Gates is among
those who have warned that terrorist groups are looking into the possibility of releasing the smallpox virus in a crowded market, or on a plane. Then there is the possibility of a scientist’s mistake. In 1978 a woman died after smallpox was released from a laboratory at the University of Birmingham, UK. In 2004 two Chinese researchers accidentally infected themselves with the SARS virus and spread it to seven other people, one of whom died. In 2014, a cardboard box full of forgotten vials of smallpox was found in a National Institutes of Health facility in Bethesda, Maryland. A year later, the US military accidentally shipped live anthrax spores to labs in the US and a military base in South Korea. It’s not impossible that human error could strike again – with catastrophic results.

Such possibilities lie behind our discomfort with what scientists have to do to further our understanding. Researchers in Rotterdam, for instance, wanted to know whether the deadly H5N1 bird flu could develop a capacity for airborne transmission like the common cold virus. Having failed to modify its genetics to achieve this, they began to pass an infection between ferrets, the animals whose response to the virus most mimics that of humans. Ten ferrets later, healthy animals were catching the virus from the cage next door. Knowing how easily H5N1 can become airborne is exactly the kind of discovery that will bolster our vigilance. It is, after all, many times more fatal than the H1N1 strain that caused the Spanish flu. At the same time, there was a huge – but understandable –
furore over whether the research should
be published, and thus be available to potential bioterrorists.

We might have to live with such dilemmas, because it is important to be ready to challenge the killer virus when it arrives. As we have seen with Aids and the common cold, developing vaccines takes time, and there is no guarantee of success, even with a concerted research effort.

****

Will we be ready? Quick suggests that our best chance lies in the world’s business leaders realising what’s at stake: economies would be devastated by the next pandemic. In 1918, Arnold points out, the British government was telling citizens it was their patriotic duty to “carry on” and make sure the wheels of industry kept turning. The result was a perfect environment for mass infection. Political leaders made similar mistakes across the Atlantic: on 12 October President Wilson led a gathering of 25,000 New Yorkers down the “Avenue of the Allies”. “That same week,” Arnold reports, “2,100 New Yorkers died of influenza.”

It’s worth noting that Spanish flu did not abate because we outsmarted it. The pandemic ended because the virus ran out of people it could infect. Of those who didn’t die, some survived through a chance natural immunity, and some were lucky enough to have maintained a physical separation from those carrying the invisible threat. The virus simply failed to kill the rest, enabling their bodies to develop the antibodies required to repel a further attack. A generation or two later, when the antibody-equipped immune systems were in the grave, and humans were immunologically vulnerable (and complacent) once again, H1N1 virus re-emerged, causing the 2009 swine flu outbreak.

As these books make clear, this is a history that could repeat all too easily in our time. Of the three, Pale Rider is perhaps the most satisfying. It has greater complexity and nuance than Arnold’s collection of harrowing tales, fascinating though they are. Spinney’s analysis is more circumspect and thus less paralysing than Quick’s masterful exposition of our precarious situation. But the truth is we need all these perspectives, and probably more, if we are to avoid sleepwalking into the next pandemic. Unlike our nemesis, humans lack focus – and it could be our undoing.
