Hygiene theatre: how excessive cleaning gives us a false sense of security

Covid-19 is a mainly airborne disease. So does our endless disinfecting and hand sanitising serve any purpose – or could it be worse than useless?

Claudia, a 26-year-old beauty worker, dreads it when her clients ask to go to the toilet. “It’s a whole other thing to clean,” she says. “They could have touched anything in there. I have to wipe down the whole thing with antibacterial spray and wipes.”

It is her job to maintain stringent cleaning protocols at the London skincare clinic where she works. When clients arrive for their appointments, Claudia checks them in, offers them a drink – the clinic only uses disposable cups or plastic water bottles – and takes them through to the treatment room.

Health campaigners call for an end to the use of the word leper

Derogatory use of the “L-word” has increased during Covid and is said to be further marginalising people with the curable disease

Health campaigners are calling for an end to the use of the word leper, saying the language frequently used by politicians and others during the pandemic has made people with leprosy even more marginalised.

The metaphor of the socially outcast “leper” has been used often, whether in media reports on stigma against early Covid-19 patients or by politicians in Italy and Brazil complaining about being seen as “leper colonies”. Campaigners now want an end to the use of what they call the “L-word”.

Richard Branson flies to edge of space in Virgin Galactic passenger rocket plane

Spaceplane went into sub-orbital flight days ahead of a rival launch by Jeff Bezos

The British entrepreneur Richard Branson has successfully flown to the edge of space and back in his Virgin Galactic passenger rocket plane, days ahead of a rival launch by Amazon founder Jeff Bezos, as the billionaires compete to kick off a new era of space tourism.

Seventeen years after Branson founded Virgin Galactic to develop commercial spacecraft and cater to future space tourists, the spaceplane went into sub-orbital flight on Sunday morning, reaching 55 miles (88km) above the Earth’s surface. The launch was slightly delayed until 10.40ET due to weather conditions at the Virgin Galactic’s operational base at Spaceport America in the New Mexico desert.

Covid live: public in England expected to wear masks when measures lift; Indonesia reports 1,007 daily deaths

UK minister says mask guidance indoors is set to stay in England; Indonesian death toll rises to total of 66,464 after deadly day

The Press Association have written up warnings expressed by Sir David Spiegelhalter on the BBC’s Andrew Marr Show today that life is likely to be “massively disrupted” by people being told to self-isolate as the number of coronavirus cases rises over the summer.

The statistician said it would make sense to get the rules “in proportion” today as vaccines minister Nadhim Zahawi confirmed the Government was looking at ways to tweak the NHS Covid app.

Few people told to self-isolate actually have an infection, and especially if they’re vaxxed, and so I do think it makes sense to get this in proportion to actually ‘what are the benefits of this massive disruption

The team are looking at how we use that app in terms of alerting people to those around them who test positive.

It’s important to look at that in a new context of this massive vaccination programme and make sure that it is fit for purpose for this new world including, for example, being able to take maybe five days, as we have piloted, of lateral flow tests and upload them to the system rather than having to self-isolate.

In Libya, Al-Wasat news is reporting that the country has recorded a record number of coronavirus cases.

The National Center for Disease Control announced the registration of 2,854 new cases of the “emerging corona virus”, in addition to 376 cases of recovery, and 8 deaths, in the highest number of infections since March 2020.

Scientist Prue Hart: ‘Sunburn causes havoc in the skin – we should avoid it’

The inflammation researcher explains the health benefits and dangers of soaking up the sun

Prof Prue Hart is head of the inflammation research group at the Telethon Kids Institute in Perth, Australia, which studies the beneficial effects of sunlight exposure on our health and whether these are the result of UV-induced vitamin D or other molecules produced in our skin upon exposure to sunlight.

What exactly happens when the sun hits our skin?
Sunlight is made up of three components: there’s the visible light that gives colour to everything we see; infrared light, which provides the heat; and ultraviolet (UV) light, which is probably the most important for our health.

Unlocking the ‘gut microbiome’ – and its massive significance to our health

Scientists are only just discovering the enormous impact of our gut health – and how it could hold the key to everything from tackling obesity to overcoming anxiety and boosting immunity

If you want to learn more about what’s going on in your gut, the first step is to turn your poo blue. How long it takes for a muffin dyed with blue food colouring to pass through your system is a measure of your gut health: the median is 28.7 hours; longer transit times suggest your gut isn’t as healthy as it could be. We are only now beginning to understand the importance of the gut microbiome: could this be the start of a golden age for gut-health science?

“The gut microbiome is the most important scientific discovery for human healthcare in recent decades,” says James Kinross, a microbiome scientist and surgeon at Imperial College London. “We discovered it – or rediscovered it – in the age of genetic sequencing less than 15 years ago. The only organ which is bigger is the liver.” And, for all that the internet may be full of probiotic or wellness companies making big health claims about gut health, “We don’t really know how it works,” he says. At the risk of sounding like the late Donald Rumsfeld, there’s what we know, what we think we know, and an awful lot that we don’t yet have a clue about.

Coronavirus live: police urge ticketless England fans not to travel to London; Fukushima to ban spectators from Olympic events

Met urges England fans not to gather in large numbers in capital for the Euro 2020 final on Sunday due to ‘ongoing public health crisis’

Seven people have died and 2,190 new people have been infected with coronavirus in Scotland in the past 24 hours.

The latest figures from the Scottish government show the daily test positivity rate is at 9% with 435 people are in hospital.

A fifth of staff could be absent from one NHS trust in England within three weeks from now, a representative organisation has warned, due in part to staff having to self-isolate amid rising coronavirus infections.

NHS Providers, a membership organisation of NHS trusts in England, said the staff shortage, also caused by people taking annual leave delayed by the pandemic, could lead to 900 operations being cancelled. It declined to name the trust.

Human body size shaped by climate, evolutionary study shows

Research combines data from fossils with climate models, revealing the effect of climate on body and brain size

A well-known pattern in human evolution is an increase in body and brain size. Our species, Homo sapiens, is part of the Homo genus and emerged about 300,000 years ago. We are much bigger than earlier Homo species and have brains three times larger than humans who lived a million years ago.

There has been debate over the factors causing humans to evolve in this way, prompting a research team led by Cambridge University and Tübingen University in Germany to combine data on more than 300 human fossils from the Homo genus with climate models to establish the role the climate played in driving evolution.

Global experts urge Boris Johnson to delay ‘dangerous’ Covid reopening

More than 100 scientists and doctors say move risks creating a generation with problems due to long Covid

Lifting the remaining Covid restrictions in England this month is “dangerous and premature”, according to international scientists and doctors, who have called on the UK government to pause reopening until more people are vaccinated.

Writing in the Lancet, more than 100 global experts warn that removing restrictions on 19 July will cause millions of infections and risk creating a generation with chronic health problems and disability from long Covid, the impact of which may be felt for decades.

World ‘must step up preparations for extreme heat’

Rising temperatures may be hitting faster and harder than forecast, say climate scientists in wake of heatwave in US and Canada

The world needs to step up preparations for extreme heat, which may be hitting faster and harder than previously forecast, a group of leading climate scientists have warned in the wake of freakishly high temperatures in Canada and the US.

Last week’s heat dome above British Columbia, Washington state and Portland, Oregon smashed daily temperature records by more than 5C (9F) in some places – a spike that would have been considered impossible two weeks ago, the experts said, prompting concerns the climate may have crossed a dangerous threshold.

Temperatures rising – Inside the 9 July Guardian Weekly

Is the world getting too hot for humans?
Get the Guardian Weekly delivered to your door

Last week’s searing temperatures in North America’s Pacific north-west were more than just another heatwave. The 49.6C registered in the tiny British Columbian town of Lytton was not simply the hottest temperature on record in Canada, it also defied computer modelling of how the world might change as emissions rise. Our global environment editor Jonathan Watts looks at how the rare phenomenon known as a heat dome is part of a growing trend towards extreme weather events, while climate science professor Simon Lewis explains why global heating is making more of the planet too hot for humans.

Starting with the Soviet invasion of the 1970s, Afghanistan has spent four decades as a battleground for proxy wars between competing nations and ideologies. As US and British troops withdraw, Emma Graham-Harrison returns to Kabul, where she spent several years as a foreign corespondent, to find little optimism and much anxiety at the resurgence of the Taliban.

Kenya in rush to vaccinate 4m children as measles cases surge

WHO reports measles outbreaks in eight African countries amid huge fall-off in jabs during Covid

Kenya has restarted its vaccination programme in an effort to tackle the re-emergence of measles, which has surged in the country during the Covid restrictions.

A 10-day campaign against highly contagious measles and rubella has begun to target 4 million children aged nine months to five years in 22 of Kenya’s 47 counties where outbreaks are highest.

What are the risks of England unlocking in the Covid third wave?

Analysis: Boris Johnson is betting big by easing rules on 19 July despite new infections rising exponentially

Lifting the final Covid restrictions in England on 19 July is a gamble for the government. Even without further easing, cases are on course to surpass 50,000 a day by mid-July. Thereafter they could swiftly exceed the winter peak of 81,000 and hit 100,000 or more, the health secretary has said. What the next wave means for lives and the NHS is still deeply uncertain – but the science offers some clues.

Climate crisis causing male dragonflies to lose wing ‘bling’, study finds

Black patterns used to attract mates can cause the insects to overheat in hotter climates

Male dragonflies are losing the “bling” wing decorations that they use to entice the females as climates get hotter, according to new research.

The results have led to the scientists calling for more work on whether this disparate evolution might lead to females no longer recognising males of their own species in the long run.

Brazilians take to streets to demand removal of Jair Bolsonaro

Calls for president’s impeachment grow amid claims government sought to profit from Covid jabs

Huge crowds of protesters have returned to the streets of Brazil’s biggest cities to demand the removal of a president they blame for more than half a million coronavirus deaths.

Tens of thousands of demonstrators hit the streets of Rio de Janeiro on Saturday morning as calls for Jair Bolsonaro’s impeachment intensified after allegations that members of his government had sought to illegally profit from the purchase of Covid vaccines.

Vaccines ‘outpaced by variants’, WHO warns, as Delta now in 98 countries

Proposals to extend Covid jabs to children in west would delay worldwide rollout, say experts, and allow deadly variants to develop elsewhere

Rich nations are sharing vaccines with low-income countries too slowly to prevent the spread of the Delta variant of Covid, risking millions of lives, the head of the World Health Organization has warned.

Dr Tedros Adhanom Ghebreyesus, the director general of the WHO, said the sharing of vaccines was “only a trickle, which is being outpaced by variants”, after it emerged that the Delta variant is now present in at least 98 countries.
