Researchers claim accurate antibody tests that could tell if millions of people in the UK have already had coronavirus could be available within two weeks.

Swiss company Roche Diagnostics claims that it has created a test with 100% accuracy and could provide hundreds of thousands to the NHS every week.
Millions of early antibody tests – designed to indicate whether someone is now immune to the disease – were ordered by the UK Government but not a single one proved accurate enough to be used on a widescale.
The 3.5 million home finger-prick tests ordered by health secretary Matt Hancock did not meet the standards agreed with the Medicines and Healthcare products Regulatory Agency (MHRA), forcing the government to row back on claims that the tests would be ready to send out to the public last month.
Roche claims its lab-based ‘Elecsys’ test can spot 100% of people who have had the virus with no ‘false negatives’ at all. The tests aim to establish whether a person has developed antibodies to the Covid-19 virus, usually after being infected by the disease, and is therefore immune from being infected again.
Knowing the scale of those who have immunity from the virus will allow the Government to plan the route back to normality much sooner.
Boris Johnson will set out plans to ease the UK out of lockdown next Sunday, with the prime minister planning to tell Britain to prepare to return to work after giving business groups the first sight of new guidelines on how to get employees safely back into offices.
In a prime-time TV broadcast to the nation next Sunday evening, the Prime Minister will set out a timeline for when workplaces and schools will reopen.

Shops, factories, warehouses and construction sites are expected to be told they can reopen following the spring bank holiday on May 25. Strict rules will have to be followed even if offices are reopening, with hot desking banned, office canteens having to stay closed and the lift capacity halved.
And in order to fire up the economy businesses who can’t enforce social distancing can still reopen as long as their staff are adequately protected with PPE or screens.
It comes as the UK announced 315 new coronavirus deaths on Sunday, bringing total fatalities to 28,446 and putting the country on course to become the hardest hit in Europe.
Another UK research firm claims it has also developed a ‘fast and accurate’ coronavirus antibody test – but it fears the NHS could miss out amid interest in Europe for the tests.
Researchers for blood-screening company Quotient, based in Edinburgh, have developed a new test for whether people are immune to Covid-19 by spotting whether a person has developed antibodies to the disease.
The tests involve using serological screening machines – each has capacity for up to 3,000 tests a day and produces results in 35 minutes with 99.8% accuracy, scientists said.
The company says it has 12 screening machines available, with a further 20 expected to be ready by the end of the year, but it has already had talks with interested parties across Europe.

Quotient is calling for the UK and Scottish governments to begin talks so that the NHS might be able to benefit.
While the UK Government says it has laboratory capability to test for coronavirus immunity, it is currently being used for survey testing of existing blood samples and the capacity is not known.
It is also attempting to develop home testing kits, rather than requiring analysis in laboratories, but so far these have proved unreliable.
On Friday, Quotient received European regulatory approval for the MosaiQ serological screening machines with 100% sensitivity and 99.8% specificity, meaning there is a low chance of a misread or ‘false positive’.
Chief executive Franz Walt – who was managing director of a laboratory that developed the first diagnostic test for Sars in 2003 – said: ‘We are truly proud to have developed such a fast and accurate test.
‘This is an outstanding performance by our teams in both Edinburgh and Switzerland.
‘We now want to make sure that we can help as many people as possible as quickly as possible. ‘We have strong roots in the UK and want to speak to ministers there so MosaiQ can be used in the amazing national effort to tackle Coronavirus and relaunch the economy.
‘We realise ministers and the NHS are incredibly busy but are keen to talk given the strong interest from across Europe in the product.’
Ed Farrell, chief operating officer at the Edinburgh office, added: ‘We’re incredibly proud of all our work here in Scotland and Switzerland.
‘We’ve got such a rich history here and we hope we can now make a difference at this challenging time.’
A Scottish Government spokesman said: ‘Health Protection Scotland, with key partners, explore all options around new antibody tests as they become available on the market.
‘The Scottish Government is working closely with the UK Government to ensure that everyone is able to access new antibody tests when they become available.
‘It is essential that any new tests are reliable, and time is needed to undertake rigorous evaluation so that there is confidence that tests are accurate.’
Roche Diagnostics said it is already ‘in dialogue’ with the NHS and the UK Government about a ‘phased roll-out of the test from mid-May’.
A spokesman added: ‘We will be able to provide hundreds of thousands of antibody tests to the UK per week.
‘Hospitals and reference laboratories can run the test on fully-automated equipment already widely installed by Roche Diagnostics at sites across the UK with results provided in 18 minutes.’
The coronavirus has killed so many people in Iran that the country has resorted to mass burials, but in neighboring Iraq, the body count is fewer than 100.

The Dominican Republic has reported nearly 7,600 cases of the virus. Just across the border, Haiti has recorded about 85.
In Indonesia, thousands are believed to have died of the coronavirus. In nearby Malaysia, a strict lockdown has kept fatalities to about 100.
The coronavirus has touched almost every country on earth, but its impact has seemed capricious. Global metropolises like New York, Paris and London have been devastated, while teeming cities like Bangkok, Baghdad, New Delhi and Lagos have, so far, largely been spared.
The question of why the virus has overwhelmed some places and left others relatively untouched is a puzzle that has spawned numerous theories and speculations but no definitive answers. That knowledge could have profound implications for how countries respond to the virus, for determining who is at risk and for knowing when it’s safe to go out again.
There are already hundreds of studies underway around the world looking into how demographics, pre-existing conditions and genetics might affect the wide variation in impact.
Doctors in Saudi Arabia are studying whether genetic differences may help explain varying levels of severity in Covid-19 cases among Saudi Arabs, while scientists in Brazil are looking into the relationship between genetics and Covid-19 complications. Teams in multiple countries are studying if common hypertension medications might worsen the disease’s severity and whether a particular tuberculosis vaccine might do the opposite.
Many developing nations with hot climates and young populations have escaped the worst, suggesting that temperature and demographics could be factors. But countries like Peru, Indonesia and Brazil, tropical countries in the throes of growing epidemics, throw cold water on that idea.
Draconian social-distancing and early lockdown measures have clearly been effective, but Myanmar and Cambodia did neither and have reported few cases.
One theory that is unproven but impossible to refute: maybe the virus just hasn’t gotten to those countries yet. Russia and Turkey appeared to be fine until, suddenly, they were not.
Time may still prove the greatest equalizer: The Spanish flu that broke out in the United States in 1918 seemed to die down during the summer only to come roaring back with a deadlier strain in the fall, and a third wave the following year. It eventually reached far-flung places like islands in Alaska and the South Pacific and infected a third of the world’s population.
“We are really early in this disease,” said Dr. Ashish Jha, the director of the Harvard Global Health Research Institute. “If this were a baseball game, it would be the second inning and there’s no reason to think that by the ninth inning the rest of the world that looks now like it hasn’t been affected won’t become like other places.”
Doctors who study infectious diseases around the world say they do not have enough data yet to get a full epidemiological picture, and that gaps in information in many countries make it dangerous to draw conclusions. Testing is woeful in many places, leading to vast underestimates of the virus’s progress, and deaths are almost certainly undercounted.
Still, the broad patterns are clear. Even in places with abysmal record-keeping and broken health systems, mass burials or hospitals turning away sick people by the thousands would be hard to miss, and a number of places are just not seeing them — at least not yet.
Interviews with more than two dozen infectious disease experts, health officials, epidemiologists and academics around the globe suggest four main factors that could help explain where the virus thrives and where it doesn’t: demographics, culture, environment and the speed of government responses.
Each possible explanation comes with considerable caveats and confounding counter-evidence. If an aging population is the most vulnerable, for instance, Japan should be at the top of the list. It is far from it. Nonetheless these are the factors that experts find the most persuasive.
The Power of Youth
Many countries that have escaped mass epidemics have relatively younger populations.
Africa — with about 45,000 reported cases, a tiny fraction of its 1.3 billion people — is the world’s youngest continent, with more than 60 percent of its population under age 25. In Thailand and Najaf, Iraq, local health officials found that the 20-to-29 age group had the highest rate of infection but often showed few symptoms.
By contrast, the national median age in Italy, one of the hardest hit countries, is more than 45. The average age of those who died of Covid-19 there was around 80.
Younger people tend to have stronger immune systems, which can result in milder symptoms, said Josip Car, an expert in population and global health at Nanyang Technological University in Singapore.
In Singapore and Saudi Arabia, for instance, most of the infections are among foreign migrant workers, many of them living in cramped dormitories. However, many of those workers are young and fit, and have not required hospitalization.
Along with youth, relative good health can lessen the impact of the virus among those who are infected, while certain pre-existing conditions — notably hypertension, diabetes and obesity — can worsen the severity, researchers in the United States say.
The Guayas region of Ecuador, the epicenter of an outbreak that may have claimed up to 7,000 lives, is one of the youngest in the country, with only 11 percent of its residents over 60 years old.
And Dr. Jha of Harvard warns that some young people who are not showing symptoms are also highly contagious for reasons that are not well understood.
Cultural Distance
Cultural factors, like the social distancing that is built into certain societies, may give some countries more protection, epidemiologists said.
In Thailand and India, where virus numbers are relatively low, people greet each other at a distance, with palms joined together as in prayer. In Japan and South Korea, people bow, and long before the coronavirus arrived, they tended to wear face masks when feeling unwell.
In much of the developing world, the custom of caring for the elderly at home leads to fewer nursing homes, which have been tinder for tragic outbreaks in the West.
However, there are notable exceptions to the cultural distancing theory. In many parts of the Middle East, such as Iraq and the Persian Gulf countries, men often embrace or shake hands on meeting, yet most are not getting sick.
What might be called “national distancing” has also proven advantageous. Countries that are relatively isolated have reaped health benefits from their seclusion.

COVID-19 is spread and will continue to share new findings.
Far-flung nations, such as some in the South Pacific and parts of sub-Saharan Africa, have not been as inundated with visitors bringing the virus with them. Health experts in Africa cite limited travel from abroad as perhaps the main reason for the continent’s relatively low infection rate.
Countries that are less accessible for political reasons, like Venezuela, or because of conflict, like Syria and Libya, have also been somewhat shielded by the lack of travelers, as have countries like Lebanon and Iraq, which have endured widespread protests in recent months.
The lack of public transportation in developing countries may have also reduced the spread of the virus there.
Heat and Light
The geography of the outbreak — which spread rapidly during the winter in temperate zone countries like Italy and the United States and was virtually unseen in warmer countries such as Chad or Guyana — seemed to suggest that the virus did not take well to heat. Other coronaviruses, such as ones that cause the common cold, are less contagious in warmer, moist climates.
But researchers say the idea that hot weather alone can repel the virus is wishful thinking.
Some of the worst outbreaks in the developing world have been in places like the Amazonas region of Brazil, as tropical a place as any.
“The best guess is that summer conditions will help but are unlikely by themselves to lead to significant slowing of growth or to a decline in cases,” said Marc Lipsitch, the director of the Center for Communicable Disease Dynamics at Harvard University.
The virus that causes Covid-19 appears to be so contagious as to mitigate any beneficial effect of heat and humidity, said Dr. Raul Rabadan, a computational biologist at Columbia University.
But other aspects of warm climates, like people spending more time outside, could help.
“People living indoors within enclosed environments may promote virus recirculation, increasing the chance of contracting the disease,” said Mr. Car of Nanyang Technological University.
The ultraviolet rays of direct sunlight inhibit the growth of this coronavirus, according to a study by ecological modelers at the University of Connecticut. So surfaces in sunny places may be less likely to remain contaminated, but transmission usually occurs through contact with an infected person, not by touching a surface.
No scientist has proposed that beaming light inside an infected person, as President Trump suggested, would be an effective cure. And tropical conditions may have even lulled some people into a false sense of security.
Countries that locked down early, like Vietnam and Greece, have been able to avoid out-of-control contagions, evidence of the power of strict social distancing and quarantines to contain the virus.
In Africa, countries with bitter experience with killers like H.I.V., drug-resistant tuberculosis and Ebola knew the drill and reacted quickly.
Airport staff from Sierra Leone to Uganda were taking temperatures (since found to be a less effective measure) and contact details and wearing masks long before their counterparts in the United States and Europe took such precautions.
Senegal and Rwanda closed their borders and announced curfews when they still had very few cases. Health ministries began contact tracing early.
All this happened in a region where health ministries had come to rely on money, personnel and supplies from foreign donors, many of which had to turn their attention to outbreaks in their own countries, said Catherine Kyobutungi, executive director of the African Population and Health Research Center.
“Countries wake up one day and they’re like, ‘OK, the weight of the country rests on our shoulders, so we need to step up,’” she said. “And they have. Some of the responses have been beautiful to behold, honestly.”
Sierra Leone repurposed disease-tracking protocols that had been established in the wake of the Ebola outbreak in 2014, in which almost 4,000 people died there. The government set up emergency operations centers in every district and recruited 14,000 community health workers, 1,500 of whom are being trained as contact tracers, even though Sierra Leone has only about 155 confirmed cases.
It is not clear, however, who will pay for their salaries or for expenses like motorcycles and raincoats to keep them operating during the coming wet season.
Uganda, which also suffered during the Ebola contagion, quickly quarantined travelers from Dubai after the first case of coronavirus arrived from there. Authorities also tracked down about 800 others who had traveled from Dubai in previous weeks.
The Ugandan health authorities are also testing around 1,000 truck drivers a day. But many of those who test positive have come from Tanzania and Kenya, countries that are not monitoring as aggressively, leading to worries that the virus will keep penetrating porous borders.
Social distance and empty spaces: UK life under lockdown (Photos)

Following the rapid spread of coronavirus (COVID-19) throughout the world in 2020, the U.K. responded by implementing a series of stringent measures from mid-March onwards. Three days after ordering schools across the country to close indefinitely, Prime Minister Boris Johnson announced strict social distancing measures on March 23, which were extended a further three weeks on April 16. These include a total ban on public gatherings of more than two people, the prohibition of travel other than for essential work and medical reasons, and that people are not to leave their homes other than to carry out one form of exercise daily.
As the nationwide lockdown continues amid rising spring temperatures across the U.K., we look at daily life around the country in pictures.
Lockdowns, with bans on religious conclaves and spectator sporting events, clearly work, the World Health Organization says. More than a month after closing national borders, schools and most businesses, countries from Thailand to Jordan have seen new infections drop.
In the Middle East, the widespread shuttering of mosques, shrines and churches happened relatively early and probably helped stem the spread in many countries.
A notable exception was Iran, which did not close some of its largest shrines until March 18, a full month after it registered its first case in the pilgrimage city of Qum. The epidemic spread quickly from there, killing thousands in the country and spreading the virus across borders as pilgrims returned home.
As effective as lockdowns are, in countries lacking a strong social safety net and those where most people work in the informal economy, orders closing businesses and requiring people to shelter in place will be difficult to maintain for long. When people are forced to choose between social distancing and feeding their families, they are choosing the latter.
Counter-intuitively, some countries where authorities reacted late and with spotty enforcement of lockdowns appear to have been spared. Cambodia and Laos both had brief spates of infections when few social distancing measures were in place but neither has recorded a new case in about three weeks.
Lebanon, whose Muslim and Christian citizens often go on pilgrimages respectively to Iran and Italy, places rife with the virus, should have had high numbers of infections. It has not.
“We just didn’t see what we were expecting,” said Dr. Roy Nasnas, an infectious disease consultant at the University Hospital Geitaoui in Beirut. “We don’t know why.”
Roll of the Dice
Finally, most experts agree that there may be no single reason for some countries to be hit and others missed. The answer is likely to be some combination of the above factors, as well as one other mentioned by researchers: sheer luck.
Countries with the same culture and climate could have vastly different outcomes if one infected person attends a crowded social occasion, turning it into what researchers call a super-spreader event.
That happened when a passenger infected 634 people on the Diamond Princess cruise ship off the coast of Japan, when an infected guest attended a large funeral in Albany, Ga., and when a 61-year-old woman went to church in Daegu, South Korea, spreading the disease to hundreds of congregants and then to thousands of other Koreans.
Because an infected person may not experience symptoms for a week or more, if at all, the disease spreads under the radar, exponentially and seemingly at random. Had the woman in Daegu stayed home that Sunday in February, the outbreak in South Korea might have been less than half of what it is.
Some countries that should have been inundated are not, leaving researchers scratching their heads.
Thailand reported the first confirmed case of coronavirus outside of China in mid-January, from a traveler from Wuhan, the Chinese city where the pandemic is thought to have begun. In those critical weeks, Thailand continued to welcome an influx of Chinese visitors. For some reason, these tourists did not set off exponential local transmission.
And when countries do all the wrong things and still end up seemingly not as battered by the virus as one would expect, go figure.
“In Indonesia, we have a health minister who believes you can pray away Covid, and we have too little testing,” said Dr. Pandu Riono, an infectious disease specialist at the University of Indonesia. “But we are lucky we have so many islands in our country that limit travel and maybe infection.”
“There’s nothing else we’re doing right,” he added.
