Covid news: UK removes quarantine requirement for arrivals from Balearics, Malta and some Caribbean islands

Latest updates: territories are added to UK’s green list or green watchlist, while more countries added to red list

Rory Boland, travel editor for consumer group Which?, said travellers still needed to be “extremely cautious” about booking trips abroad.
He said: “Countries can be downgraded quickly and with little warning, as we saw with Portugal, while several European countries have introduced quarantine requirements for UK residents. “Restrictions around international travel are changing regularly and when they do, the cost to holidaymakers is significant. “Most providers will not pay refunds if a country is moved from green to amber, and ‘free’ amendments are often anything but, with many companies requiring significant notice of any changes and bookings for new dates usually costing hundreds of pounds. Travel insurance is also unlikely to pay out in these circumstances. “It is only advisable to book if you are able to do 14 days’ quarantine, can be flexible about destination and dates, and book with a provider that guarantees refunds in the event of traffic light changes or quarantine requirements.”

Eluned Morgan MS, minister for health and social services in Wales, said: “International travel is resuming but the pandemic is not over and protecting people’s health remains our main priority.

“Our strong advice continues to be not to travel overseas unless it is essential because of the risk of contracting coronavirus, especially new and emerging variants of concern.

UK analysis shows people who drank coffee had 49% reduced risk of dying from the condition

From espresso to instant, coffee is part of the daily routine for millions. Now research suggests the brew could be linked to a lower chance of developing or dying from chronic liver disease.

Chronic liver disease is a major health problem around the world. According to the British Liver Trust, liver disease is the third leading cause of premature death in the UK, with deaths having risen 400% since 1970.

High stress may make ‘broken heart syndrome’ more likely, study finds

Posted on by

Condition also known as takotsubo cardiomyopathy is brought on by an acute emotional shock

Two molecules associated with high stress levels have been implicated in the development of broken heart syndrome, a condition that mainly affects post-menopausal women and is usually brought on by severe stress, such as the loss of a loved one.

The syndrome, formally known as takotsubo cardiomyopathy, is characterised by weakening of the heart’s main pumping chamber and was first identified in 1990 in Japan. It looks and sounds like a heart attack and is consequently often confused for one.

Research found marked differences in immune response of medical staff six months after contracting virus

Previous infection with coronavirus does not necessarily protect against Covid in the longer term, especially when caused by new variants of concern, a study on healthcare workers suggests.

Researchers at Oxford University found marked differences in the immune responses of medical staff who contracted Covid, with some appearing far better equipped than others to combat the disease six months later.

Analysis: Lockdown extension brings questions on when and how UK can draw a line under social distancing

The Commons vote to delay step four of England’s roadmap out of lockdown has focused attention on when and how the country can draw a line under social distancing and, in the words of the prime minister, “learn to live with the virus”.

While the surge in cases in Blackburn – one of the original Delta variant hotspots – may have peaked for now, Public Health England expects recent rises in the north-west to be mirrored across the UK. What that means for hospitals and lives will become clearer in the next four weeks.

New drug cuts deaths among patients with no Covid antibodies

Oxford University trial reports cocktail of manmade antibodies reduces fatalities by a fifth

A new drug has been found to cut Covid deaths by a fifth among the sickest patients in hospital and may change official practice so that every patient with coronavirus will have an antibody test before they are admitted.

The Recovery trial based at Oxford University has found a third drug that can help Covid patients recover in hospital – but this one is the first to tackle the virus itself, rather than the inflammation that develops in the later stages of the disease.

Developed by Australian and European researchers, the film works by converting infrared light into light visible to the human eye

A transparent metallic film allowing a viewer to see in the dark could one day turn regular spectacles into night vision googles.

The ultra-thin film, made of a semiconductor called gallium arsenide, could also be used to develop compact and flexible infrared sensors, scientists say.

Cash incentives and gifts offered to fulfil target of vaccinating 40% of population by end of month

China is on track to administer 1bn vaccine doses by the end of this week, after bolstering production and distribution networks in an ambitious drive to vaccinate 40% of the population by this month.

Chinese authorities have been encouraging people to take the free and voluntary doses with cash incentives, gifts and colour-coded signage to laud or shame businesses depending on vaccination rates, as well as the promise of protection against Covid-19.

Delaying England’s Covid reopening ‘could keep thousands out of hospital’

Research backs four-week delay on lifting restrictions to allow more people to get jabs

Ministers have been told that a four-week delay to easing all Covid restrictions would probably prevent thousands of hospitalisations, as Boris Johnson prepares to tell the English public they will have to wait up to another month for “freedom day”.

The government roadmap out of lockdown earmarks 21 June for the last remaining coronavirus restrictions to be lifted in England, but the prime minister is expected to announce on Monday that the timetable will be pushed back by two to four weeks amid a rapid rise in cases of the Delta variant first detected in India.

Why are women more prone to long Covid?

Posted on by

While men over 50 tend to suffer the most acute symptoms of coronavirus, women who get long Covid outnumber men by as much as four to one

In June 2020, as the first reports of long Covid began to filter through the medical community, doctors attempting to grapple with this mysterious malaise began to notice an unusual trend. While acute cases of Covid-19 – particularly those hospitalised with the disease – tended to be mostly male and over 50, long Covid sufferers were, by contrast, both relatively young and overwhelmingly female.

Early reports of long Covid at a Paris hospital between May and July 2020 suggested that the average age was around 40, and women afflicted by the longer-term effects of Covid-19 outnumbered men by four to one.

Drop Covid vaccine patent rules to save lives in poorest countries, Britain and Germany told

G7 summit hears move would slash the cost of jabs and accelerate rollout of programmes across the developing world

Britain and Germany were under intense pressure on Saturday to drop their resistance to proposals that would slash the cost of Covid-19 vaccines, following accusations that an agreement at the G7 summit to fund a billon doses will give the world’s poorest countries “crumbs from the table”.

Aid agencies said rules that protect drug patents from being illegally copied must be waived during the pandemic to accelerate the rollout of vaccines and save lives across the developing world.

Should England open up on 21 June? The factors Johnson must consider

Posted on by

The prime minister has a host of problems to weigh up before deciding to remove all legal restrictions on social contact

The key issue is the extent to which infections of the Delta variant first detected in India will lead to hospitalisations and deaths. The problem is that it’s too early to say. Because of the lag between cases and admissions to hospital, many experts say a short delay could be a major benefit to understanding that relationship. “With the current knowledge about Delta, we can’t really predict the size of that wave,” said Anne Cori of Imperial College London’s modelling group. “Delaying the easing allows time to accumulate more evidence about the characteristics of Delta. And I hope in a few weeks, we would be in a better position to predict what the epidemic may look like in the next few weeks or months.”

David Eagleman: ‘The working of the brain resembles drug dealers in Albuquerque’

The neuroscientist, broadcaster and author on the evolution of the brain, the mystery of consciousnesss, and why the next generation will be much smarter than us

David Eagleman, 50, is an American neuroscientist, bestselling author and presenter of the BBC series The Brain, as well as co-founder and chief executive officer of Neosensory, which develops devices for sensory substitution. His area of speciality is brain plasticity, and that is the subject of his new book, Livewired, which examines how experience refashions the brain, and shows that it is a much more adaptable organ than previously thought.

For the past half-century or more the brain has been spoken of in terms of a computer. What are the biggest flaws with that particular model?
It’s a very seductive comparison. But in fact, what we’re looking at is three pounds of material in our skulls that is essentially a very alien kind of material to us. It doesn’t write down memories, the way we think of a computer doing it. And it is capable of figuring out its own culture and identity and making leaps into the unknown. I’m here in Silicon Valley. Everything we talk about is hardware and software. But what’s happening in the brain is what I call livewire, where you have 86bn neurons, each with 10,000 connections, and they are constantly reconfiguring every second of your life. Even by the time you get to the end of this paragraph, you’ll be a slightly different person than you were at the beginning.

Innova tests’ performance not proven and they should be returned to manufacturer or thrown in bin, says FDA

The US Food and Drug Agency (FDA) has raised significant concerns about the rapid Covid test on which the UK government has based its multibillion-pound mass testing programme.

In a scathing review, the US health agency suggested the performance of the test had not been established, presenting a risk to health, and that the tests should be thrown in the bin or returned to the California-based manufacturer Innova.

Delta variant causes more than 90% of new Covid cases in UK

Posted on by

Variant first discovered in India is thought to spread more easily and be more resistant to vaccines

More than 90% of Covid cases in the UK are now down to the coronavirus Delta variant first discovered in India, data has revealed, as the total number of confirmed cases passed 42,000.

Also known as B.1.617.2, the Delta variant has been linked to a rise in Covid cases in the UK in the past weeks. It is believed to spread more easily than the Alpha variant, B.1.1.7, that was first detected in Kent, and is somewhat more resistant to Covid vaccines, particularly after just one dose. It may be also associated with a greater risk of hospitalisation.

Organisation urges governments to be cautious as societies open up and Delta variant advances

Covid-19 infections, hospitalisations and deaths are falling fast across Europe, but the risk of a deadly autumn resurgence remains high as societies open up and the more transmissible Delta variant advances, the World Health Organization (WHO) has said.

The warning came as new case numbers continued to plunge in most of the continent, falling in some areas to their lowest levels since August, and multiple governments, including France and Germany, relaxed restrictions further.

Covid distancing may have weakened children’s immune system, experts say

Posted on by

End of social distancing and mask-wearing could leave children vulnerable to common bugs

Scientists are concerned that measures to combat Covid-19 have weakened the immune systems of young children who have not been able to build up resistance to common bugs, leaving them vulnerable when mask-wearing and social distancing eventually end.

Contact with viral pathogens happens on a fairly regular basis and although it does not always lead to sickness, the exposure helps shore the immune system against the threat should the bugs be encountered again.
