NHS Test and Trace system not tracing enough contacts of coronavirus cases
The NHS Test and Trace system, which is designed to identify people who might have been exposed to people who have tested positive for coronavirus, only reached 38 per cent of known contacts of people diagnosed with coronavirus, according to leaked data obtained by Channel 4 News. The Scientific Advisory Group for Emergencies (SAGE), the government’s official advisory group for the pandemic, say the system needs to reach 80 per cent to be effective. Out of 4634 contacts provided to NHS Test and Trace by people who were confirmed to have coronavirus between 28 and 31 May, only 1749 were contacted.
UK prime minister Boris Johnson told MPs today that the government’s current alert level for coronavirus, a system designed to inform people about the severity of the pandemic, “does allow” easing of restrictions. This contradicts the government’s own guidance, which under the current alert level of 4, says current restrictions must remain. The Times reported yesterday that Johnson hoped to reduce the virus alert level from 4 to 3 to justify the easing of restrictions this week, but the change was prevented by Chris Whitty, the chief medical officer for England.
The World Health Organization and several countries changed their policies on covid-19 treatments on the basis of data from a study in the Lancet which is now being questioned, a Guardian investigation has revealed. The data used in the study were provided by US-based health analytics company Surgisphere, and suggested that the anti-malarials hydroxychloroquine and chloroquine could increase the risk of death in covid-19 patients, which led to the suspension of clinical trials investigating whether these drugs could be used to treat covid-19. But the Lancet has released an “expression of concern” about the validity of the data, a step sometimes made before a study is retracted. There are also concerns about a separate New England Journal of Medicine study that also used data provided by Surgisphere.
Removing coronavirus restrictions too quickly and having to reintroduce lockdowns will be worse for the global economy than gradually easing restrictions, according to a modelling study published in Nature Human Behaviour today. The study modelled three different scenarios for lifting lockdowns, including one in which restrictions are relaxed gradually over 12 months and two where all restrictions are lifted immediately but then reintroduced within one year. The researchers found that the impact of supply-chain losses on global GDP in the scenario with gradual easing was projected to be about 10 to 20 per cent lower than in the scenarios with recurrent lockdowns.
Black people received a disproportionately high number of fines for lockdown breaches in London according to Metropolitan police figures. Of the 973 fines issued between 27 March and 14 May, black people received 26 per cent despite only making up 12 per cent of London’s population.

Covid-19 death for severe cases is 70 times higher in people over 80
People over 80 in England who are hospitalised with covid-19 are 70 times more likely to die compared to people under 40, according to a report from Public Health England. According to the report, the probability of death is about three times higher for people aged 40 to 49, nine times higher among those aged 50 to 59, 27 times higher for those in their 60s and 50 times higher for those in their 70s. However, these probabilities were calculated from cases where people had severe enough symptoms to get tested for covid-19. The analysis did not take milder cases into account.
The data also shows that black people are between two and three times more likely to be diagnosed with coronavirus than white people, and death rates from covid-19 are highest among people from black and Asian ethnic groups. People of Bangladeshi ethnicity had the highest risk of death of any ethnic group, around twice the risk compared to white people. People of Chinese, Indian, Pakistani, Other Asian, Caribbean and Other Black ethnicity had between a 10 and 50 per cent higher risk than white people.
The analysis didn’t take people’s occupation or pre-existing health conditions into account, which may go some way to explain the differences in infection and death rate between ethnic groups. However, other studies suggest these factors don’t fully explain the disparity.

Keeping two metres away from other people is much more effective at limiting the transmission of coronavirus than one metre, with the risk halving for every additional half metre of distance up to three metres, according to a review of 172 studies published in The Lancet. Wearing a face covering and eye protection can also significantly reduce the spread of the virus.
There were 56,308 more deaths in England and Wales between 27 March and 22 May than would normally be expected, according to the Office for National Statistics.
The UK government’s presentation of coronavirus testing numbers is misleading, unclear and difficult to understand, David Norgrove, the head of the UK Statistics Authority, wrote in a letter to health minister Matt Hancock today. Norgrove said the way the government presented the numbers seemed to be designed to show “the largest possible number of tests, even at the expense of understanding.”

Restrictions eased in England despite warnings from public health directors
The NHS Test and Trace programme is not robust enough to support the UK government’s easing of coronavirus restrictions and prevent a resurgence of virus cases, according to an article published yesterday by the Association of Directors of Public Health (ADPH), a body that represents public health directors, specialists who oversee public health activities in UK local authorities. The ADPH says restrictions should not be eased because the daily death toll is not consistently falling, particularly in care homes. They also say that easing restrictions too quickly will make it hard to calculate the R number for the disease, a measure of how fast coronavirus infections are spreading.
The easing of restrictions in England from today includes people being allowed to meet outdoors in groups of up to six, while maintaining a two metre distance between people from different households, as well as the reopening of car showrooms and outdoor markets.
Pupils in reception, Year 1 and Year 6 in England were allowed to return to school today, but 46 per cent of parents and carers may have kept their children at home, a survey of primary school leaders by the National Foundation for Educational Research suggests.

The total number of confirmed coronavirus cases around the world has passed 6.2 million, and more than 373,000 people are confirmed to have died from the disease.
The UK government has not released data about how many people are tested for coronavirus since 22 May. The official numbers, which say there were 115,275 tests performed on 30 May with a capacity for 205,634 tests, also “double count” by including nasal swabs and saliva tests on the same person.
Only 197 cases of influenza virus were confirmed in Australia this May, compared to 30,567 in the same month last year, according to Australia’s Department of Health. This huge decrease in flu cases may be due to social distancing measures introduced to limit the spread of coronavirus. Australia’s flu season usually peaks during its winter months, from June to August.
There is only one person with active covid-19 in New Zealand, according to the latest figures from New Zealand’s health ministry.

29 May
14 per cent of people in the UK said they have had friends or family visit them at home, according to a survey conducted between 20 and 22 May by researchers at King’s College London and Ipsos MORI. Only 5 per cent of people reported having broken lockdown restrictions in this way in a similar survey done between 1 and 3 April.
The poll surveyed 2254 people in the UK aged 16 to 75. Of these, 92 per cent of people said they are maintaining a two metre distance from other people in public spaces in accordance with government guidelines and 38 per cent are wearing a face mask or covering outside.
The survey found that 40 per cent of people think they will catch the coronavirus by the end of the year. 35 per cent of people said they had delayed seeking medical advice or treatment for non-coronavirus conditions and 17 per cent said they’d had to delay or cancel treatment due to disruptions caused by the pandemic. Almost half of those surveyed – 48 per cent – reported feeling more anxious and depressed than usual.
Other coronavirus developments
The UK government’s coronavirus alert level remains at 4, which corresponds to high or rising virus transmission, a Downing Street spokesperson told journalists today. Further easing of restrictions in England is set to begin on Monday, despite the government’s own guidelines suggesting that an alert level of 4 warrants continuation of “current social distancing measures and restrictions.” There were 1887 positive tests for coronavirus in the UK on 27 May.

England’s test and trace system won’t be fully operational until end of June
England’s test and trace system, which is designed to identify people who might have been exposed to people who have tested positive for coronavirus, won’t be fully operational until the end of June, Dido Harding, who is leading the NHS Test and Trace scheme, told MPs today. UK prime minister Boris Johnson said last week that the system would be in place and able to track 10,000 people a day using text, phone and email by 1 June. Harding also described the NHS covid-19 contact tracing app, which was meant to launch on 15 May but was delayed until 1 June, as “the cherry on the cake rather than the cake itself.”
In England, people will be allowed to meet in public places and private gardens in groups of up to six starting on Monday, and in Scotland, groups of up to eight people from two different households will be allowed to meet outdoors from tomorrow. Northern Ireland allowed groups of up to six people to meet outside from 18 May. People from different households will still be required to keep a distance of two metres.
Other coronavirus developments
There have been more than 100,000 deaths from covid-19 in the US since the outbreak began, according to Johns Hopkins University, the largest number of any country. The number of daily new confirmed cases has been rising over the last week in 18 states, including California, Florida and Louisiana. In New York, the country’s worst-hit state with more than 369,000 cases in total, the number of daily new cases has fallen to around 1,200, down from a peak in early April of over 10,000 a day.
An analysis by the Financial Times suggests the UK had the second highest rate of coronavirus deaths among 19 countries with comparable data. The UK registered 59,537 more deaths than would normally be expected to occur since the week ending 20 March, a death rate of 891 per million people, higher than Italy and the US, and second only to Spain. The FT analysis also found a link between countries that locked down earlier in their outbreaks and lower death tolls.
