Some occupational groups have experienced higher rates of both COVID-19 infections and related deaths. Many people who work within these groups are involved in caring for people or patients that are more likely to be infected, or have otherwise been unable to work from home during the peaks of transmission. Which occupations have been most affected, what factors are contributing to this risk and are some sectors of the population being impacted more than others?

BCIs are a type of Neural Interface (NI), a broader family of devices that interact with an individual’s brain and nervous system. The term BCIs was first used in 1973. Since then, development has mainly focused on researching brain function and medical applications, such as assisting a patient with paralysis to communicate or control a prosthetic such as a limb or a wheelchair. BCIs have been highlighted by the Chief Medical Officer as an emerging technology with therapeutic potential. Other sectors, such as entertainment and defence, are also developing BCIs, while companies and entrepreneurs are investing in heavily in BCIs and other NIs.
BCIs present ethical challenges, many of which also apply more widely to other types of NI. In September 2019, a report by the Royal Society suggested that the UK could lead in developing responsible regulation and new applications for NIs.
- BCIs collect data from the brain and can translate it into control commands for electronic devices.
- BCIs can be categorised as invasive or non-invasive depending on where the device’s sensors are placed. Invasive BCIs use sensors that are implanted during a surgical procedure and non-invasive BCIs use sensors that are located outside the skull.
- Since the 1970s BCI research and development has been centred on medical applications, mostly focused on restoring lost function in patients, for example, following paralysis.
- Due to a range of technical challenges, practical clinical use has not yet been achieved. However, investment in BCIs is increasing and innovative approaches are being developed to address these issues.
- BCIs are also being developed outside medicine for brain-controlled gaming and improvement of cognitive functions, for which some companies already market consumer products.
- Companies are developing non-invasive BCI headsets to play computer games. These would allow users to control actions within the game via thought.
- The MoD is investigating how BCIs can enhance different cognitive abilities, including decision-making and sensory processing. In the U.S, the Defence Advanced Research Project Agency has an extensive funding programme on developing NIs and BCIs for military use.
- Given the pivotal role of the brain to human functioning, the ethics of using BCIs has been the subject of recent debate. Issues include safety, privacy, fair access, assessing risks versus benefits and attributing responsibility for actions involving BCIs.
- In 2013, the Nuffield Council on Bioethics published an ethical framework for technologies that interface with the brain.
- In the UK, there is no regulation specific to BCI technology. However, BCI systems may fall within the scope of the EU Medical Devices Regulation (MDR) if they are intended for medical use. BCI devices that fall outside the scope of the MDR will still be governed by consumer protection laws.
- New regulatory approaches may be needed to help stimulate further innovation and to ensure privacy and safety of BCI devices.

During the first 6 months of the pandemic, people from ethnic minority groups were more likely to have COVID-19 disease and also more likely to experience severe outcomes from infection, including death. Lockdown measures have also disproportionately affected some communities more than others. What is driving this increased prevalence and death rates in ethnic minority groups? To what extent is it due to biology or pre-existing health? Or does it represent a continuation and exacerbation of social inequalities?
On 9 September, the Prime Minister announced a moonshot plan for mass COVID-19 testing. Recently there have been capacity issues in the NHS Test and Trace programme and current technologies cannot be scaled easily to millions of tests per day. So, how is COVID-19 testing undertaken, how reliable are current tests, and what technologies or strategies are emerging that would make this moonshot feasible?
