The Covid-19 crisis has exposed the effects of government neglect on Britain’s once-trailblazing public health strategiesIt’s difficult to imagine that Britain was, until very recently, regarded as a leader in preparing for pandemics. Countries such as Singapore once looked to the UK for lessons in how to prepare for and respond to outbreaks. Now, it’s the other way around. With its number of coronavirus cases exceeding 170,000, and deaths set to climb above 40,000, the UK appears to be playing catch-up with the rest of the world.Britain’s failure to shatter the coronavirus curve couldn’t be further out of step with its past reputation as a leader in this area. The UK’s global health strategy, launched under New Labour in 2008, was a game-changer in the field of global health. The strategy identified how, in an interconnected world, an infectious outbreak in another country was a direct threat to the UK. By building health capacity elsewhere in the world, the government recognised that it could protect its own borders from infectious outbreaks – reflecting the Blairite logic that interventions abroad would bolster security at home.

Rather than admit responsibility for being behind the curve, ministers instead seek to delegitimise the media for asking questions about why Britain failedIbsen’s 19th-century play An Enemy of the People is a political drama about a physician who tries to save his town from water pollution only to wind up as a scapegoat. For the doctor the issue is health; after testing the water supply he urges a shutdown and new pipes to be laid to save lives. The town’s mayor is concerned about the economic cost. Better, the politician reasons, to keep the town open and correct the problem gradually. In the moral combat that ensues it is the doctor who becomes alienated from the town he struggled to protect. The play’s message is a counsel of democratic despair: that might is more powerful than right.This insight has not been lost on the British government. Like Ibsen’s fictional politician, ministers refused to see the viral threat. Boris Johnson did not want to contemplate a draconian response. When they did act, ministers found they were behind in a global race for critical resources such as ventilators, testing capacity and personal protective equipment. The failure to move decisively to suppress the pandemic lies at the root of the mess. Rather than admit responsibility for being behind the curve, ministers refuse to apologise and instead seek to delegitimise the media for asking questions about why Britain failed.

One figure in particular is being closely scrutinised as ministers decide when to end lockdownR, or the “effective reproduction number”, is a way of rating a disease’s ability to spread. It’s the average number of people on to whom one infected person will pass the virus. For an R of anything above 1, an epidemic will grow exponentially. Anything below 1 and an outbreak will fizzle out – eventually.At the start of the coronavirus epidemic, the estimated R for coronavirus was between 2 and 3 – higher than the value for seasonal flu, but lower than for measles. That means that each person would pass it on to between two and three people on average, before either recovering or dying, and each of those people would each pass it on to a further two to three others, causing the total number of cases to snowball over time.

My wife, Eva Wickham, who has died aged 76, worked for the Inner London Education Authority in Lambeth as an educational psychologist for two decades from 1971. When Ilea was abolished in 1990, she moved to Wandsworth’s educational psychology service, where she remained until her retirement in 2006.She had a deep aversion to doing nothing and in retirement she soon found herself chairing the governing body of a local primary school. Throughout her adult life Eva was involved in various charity projects, usually involving children. She was a trustee for Cave, a literacy project in Clapham, worked as a volunteer breast feeding counsellor for the National Childbirth Trust and, most recently, was a trustee for Lambeth Home Start.

Stress can affect the quality and length of sleep. Scientists have been collecting dream data during the coronavirus crisis, with surprising resultsFrom going to bed too late thanks to endless scrolling through theories about the pandemic, to waking up in the night worrying, it is safe to say that Covid-19 is wreaking havoc with our sleep. A major survey conducted by King’s College London with Ipsos Mori showed that two in five people in the UK have reported sleep disturbance. Prof Bobby Duffy, the research lead and director of the Policy Institute at King’s, says: “There is a clear relationship between increased stress and impact on sleep; 53% of those who said they found the crisis stressful reported sleep difficulties.” But many people around the world are also experiencing a new phenomenon: pandemic dreams.Most of us don’t often remember our dreams, but the anxieties of life in isolation and disruption to our normal sleep-wake cycles seem to be changing that. Several researchers are collecting dream data during the pandemic, including Dr Deirdre Barrett, a clinical and evolutionary psychologist at Harvard Medical School. She explains that, although it seems that we are dreaming more often, we are actually remembering them better because we’re sleeping more, but also waking up more during the night. “With more options to sleep, including napping in the day and longer lie-ins, dream recall is maximised, but you have to wake up out of a dream to remember it. We know that increased stress is a cause of waking frequently during the night.” Continue reading...

The Zen neighbourhood, on the outskirts of Palermo, feels abandoned by the government — and the mafia have moved inAlongside the postcard-perfect images of Italy’s silent and deserted Renaissance squares under lockdown, there are the filthy streets of the Zen neighbourhood on the northern outskirts of Palermo. In one of the poorest districts in Europe, a stronghold of the local mafia, there appears no light at the end of the tunnel despite Italy being set to begin its route out of lockdown from next week.Unemployment skyrocketed in the Zen – built in the 1960s as the city’s Zona Espansione Nord and falling into dilapidation in the decades after – when retailers were forced to close in order to contain the spread of Covid-19.

Preliminary results of US government trial show patients who received drug recovered faster than othersHopes of an effective drug treatment for coronavirus patients have risen following positive early results from a trial of remdesivir, a drug first tried in Ebola patients.Data from the trial on more than 1,000 severely ill patients in 75 hospitals around the world show that patients put on the drug recovered 31% faster than similar patients who were given a placebo drug instead. Remdesivir cut recovery time from a median of 15 days to 11. Continue reading...

Study says volunteers reported a rapid reduction in desire without impaired self-controlThe risk of some men sexually abusing children could be quickly reduced by a drug that lowers testosterone levels, researchers have found.The team behind the project, which was put up for crowdfunding four years ago, said the drug – degarelix acetate – produced the results in men with paedophilic disorder in just two weeks. The drug was developed as a treatment for prostate cancer treatment and blocks the production of testosterone. Continue reading...

Making chutney | Lockdown marmalade | Father Jack and Trump | Mathematical fright | Morse code clappingFor years I have used a WI friend’s recipe for chutney (The power of pickles: a guide to preserving almost everything – from jam-making to chutneys, 28 April) – equal weights of onions, apples (eaters or cookers), dates, sultanas and brown sugar, chopped up into a bowl and covered with vinegar for 24 hours, stirred and put into jars. No stinking the house out with boiling, no freezing or refrigerating, and delicious chutney. Even easier than making marmalade with tins of prepared fruit.

Influential chief scientific adviser to the government who made politicians and scientists think about the public they servedIf you asked Bob May, Lord May of Oxford, to explain the bewildering eclecticism of his scientific interests, he would say that he liked playing games and solving puzzles. His idea of play was anything but frivolous: to him mathematics was “no more – and no less – than thinking very clearly about something”. The things he chose to think about were complex systems: from modelling the survival of species in diverse ecosystems to the spread of Aids, and, later, the stability of global finance.An uncompromising and bluntly spoken Australian, May, who has died aged 84, reached the highest levels of the British scientific and political establishment. As chief scientific adviser to the government from 1995 to 2000, he shook up the cosy relationship between politicians and the scientific community, and made both think about the public they served. A scientific career conducted across three continents ensured that his ecological models, forensically developed and delivered with exemplary clarity, have been influential internationally.
