UK coronavirus alert level lowered from four to three
The UK’s chief medical officers today said the country’s coronavirus alert level has reduced from four to three. This level of the alert system corresponds to the virus being in general circulation, but at a level where it’s possible to gradually relax some restrictions. However, restrictions in England have already been progressively relaxed throughout June, even while the alert level remained at four – which corresponds to high or exponentially rising levels of the virus and warrants continued social distancing.
For the first time, the government today published the daily rate at which coronavirus infections are growing, alongside the UK’s R number, which remains unchanged at around 0.7 to 0.9. For the UK as a whole, the growth rate is believed to be anywhere between -2 per cent and -4 per cent, meaning that infection numbers are declining slightly. At a regional level there is a chance that new cases may be growing in London. However, the government’s science advisers believe that growth in infection numbers is unlikely.

People from South Asian backgrounds in the UK are 20 per cent more likely to die from covid-19 in hospital than white people, according to a preliminary study that analysed data on patients at 260 hospitals. This disparity was partly explained by higher levels of diabetes, the researchers who did the study told the BBC.
China’s Centre for Disease Control and Prevention (CDC) says that genetic analysis suggests that the coronavirus causing a new outbreak in the capital Beijing probably came from Europe. Earlier this week, CDC director Gao Fu said the virus may have been spreading in Beijing as early as the start of May.
Microbiologists at University College London, UK, are calling for widespread surveillance of pets, livestock and wild animals to measure the prevalence of coronavirus. There have been limited studies on animal susceptibility to the virus, they wrote in a commentary published in The Lancet Microbe on Thursday, with conflicting data on some animals, such as pigs.

NHS Test and Trace still not reaching enough contacts of coronavirus cases
The UK government’s contact tracing scheme for England only reached 73 per cent of people diagnosed with coronavirus between 4 and 10 June, government figures revealed today. This falls short of the 80 per cent target recommended by the government’s Scientific Advisory Group for Emergencies (SAGE) for the second week in a row. Of the 5949 people who tested positive for coronavirus during this time, NHS Test and Trace only managed to contact 4366. Yesterday, Independent SAGE – an alternative group of scientists – published a report saying the 80 per cent target is currently “impossible” to meet.
In addition, not everyone contacted by NHS Test and Trace was reached quickly enough. Only 75 per cent of people who were contacted were reached within the government’s target of 24 hours. 8.6 per cent of people were only contacted after 72 hours, when the chance that an infected person has already spread the virus is high.
350,000 people in Beijing, China have been contacted to arrange testing and 22 million people in the city are now under lockdown conditions after a new outbreak of coronavirus cases linked to the Xinfadi food market. The new outbreak may have started a month earlier than first thought, due to some people not experiencing symptoms, said Gao Fu, the director of China’s Center for Disease Control and Prevention at a seminar on Tuesday. Officials in Beijing reported 21 new coronavirus cases today, down from 31 on Wednesday and bringing the new outbreak’s total to 158 cases.
An estimated 33,000 people in England outside of hospitals and care homes had covid-19 between 31 May and 13 June, according to preliminary results from a random swab testing survey by the Office for National Statistics (ONS). This is lower than the 149,000 people thought to have been infected between 3 and 16 May and is consistent with ONS modelling that suggests the number of people testing positive in England has been falling since 26 April.
An American Airlines passenger was removed from a flight on Wednesday after refusing to wear a face covering in accordance with the airline’s new covid-19 safety policy, introduced earlier this week.
