What is the ‘Wuhan coronavirus (2019-nCoV)’ and what do we know about it so far?
Dr John Tregoning (JT) from Imperial’s Department of Infectious Disease spoke to the School of Public Health’s Prof Steven Riley (SR) about the coronavirus outbreak that recently began in Wuhan, China.


Who has been working on the outbreak epidemiology at Imperial College London?

SR: I work as part of the MRC Centre for Global Infectious Disease  Analysis and the Abdul Latif Jameel Institute for Disease and Emergency Analytics centre with Prof Neil Ferguson, Dr Natsuko Imai, Dr Ilaria Dorigatti, Dr Anne Cori Prof Christl Donnelly, Prof Azra Ghani and Dr Marc Baguelin.

So what is this new coronavirus?

SR: It is a viral infection that was first discovered in the Chinese city of Wuhan in 2019 that has been associated with a number of cases of pneumonia – an infection of the tissue in the lungs. You might see it being called ‘2019-nCoV’, which stand for novel (or new) coronavirus. More information has been provided by the World Health Organisation. (more…)

Alive and ticking: Is Lyme disease on the rise in the UK?

Lyme disease UK

Justin Bieber’s recent Lyme disease diagnosis has brought the disease into the public eye. Professor Gareth Tudor-Williams explores whether there is a link between tick behaviour and a rise in reported cases.


It’s a fact that every time a high profile individual reveals that they have Lyme disease – the latest being singer Justin Bieber – there is an appreciable spike in internet searches, followed a short while later by an increase in the number of blood samples being sent for testing to the Public Health England national reference laboratory at Porton Down.

So this trend would suggest that the publicity about Lyme disease increases health-seeking behaviour in this country, which in turn leads to more cases being diagnosed.

All of which begs several questions. Is the incidence truly rising or are more people being diagnosed who would not previously have been tested? Are there significant numbers of people living in the UK with undiagnosed and therefore untreated infection?  What proportion of untreated infected individuals develop long-term health problems?

Could weight loss improve infertility in obese men?

weight loss infertility

With NHS funding for IVF diminishing, Imperial researchers are looking at weights loss as a way to support men who have obesity-related reproductive dysfunction.


Infertility is the inability to have children after 12 months of regular unprotected intercourse and is fairly common, affecting 1 in 7 couples. Male factor infertility refers to infertility secondary to poor sperm quality, and while it is talked about less than female infertility, it is responsible for 40% of infertile cases. Obesity is a rising global epidemic, so it is no surprise that a quarter of men attending fertility centres are obese.

During the last few decades, tremendous advances have taken place in the treatment of women diagnosed with infertility. However, little progress is made for couples with male factor infertility. Therefore, the only therapy offered to couples is assisted reproduction, such as in-vitro fertilisation (IVF) therapy. IVF is effective but with NHS funding diminishing it can be expensive, as well as having potentially life-threatening complications for the female partner such as ovarian hyper-stimulation syndrome. That’s why we need to look at other options for couples affected by infertility. (more…)

Second year of medical school: from virtual reality to refugee health


Second year of medical school

Khadija Mahmoud reflects on the highlights from the past year of medical school – from a virtual reality project that sparked an interest in refugee health to attending One Young World Summit.


I never imagined that my medical degree would involve a project working with chemical engineers to study the effects of a virtual reality (VR) application! During the second year of MBBS Medicine at Imperial College School of Medicine, we undertake a three-week research experience called Clinical Research Innovation (CRI).

I worked with our Digital Learning Hub  and the Matar Fluid Group to study the effects of using 3D virtual reality in learning. Our research focused on transforming medical education in classrooms by increasing interactivity. Working with two others, we managed to plan, design and conduct a study of 36 participants, producing a poster to present our findings at Imperial’s annual science festival for second-year medical students. The VR application showed fluid dynamics within a liquid flow with real-time feedback and could easily replicate blood flow in an artery to allow exploration of pathologies in relation to this.  (more…)

My fight against medical myths and fake news on social media

Dr Amalina Bakri

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

Our final wise woman, Dr Amalina Bakri, provides an insight into the role of social media in fighting medical misinformation online.


Some people are often surprised to hear that I’m a General Surgeon (speciality trainee) with a significant social media presence – over one million followers across Twitter and Instagram. I use social media to communicate what I’m passionate about, and that is an evidence-based approach to lifestyle medicine and disseminating accurate health information.

As the internet has matured, social media has developed and become an intrinsic part of many people’s lives. Some commonly use social media as a trusted source of information or news. But in the current climate, fake news or misinformation spreads like wildfire on social media, making it hard for individuals to see the true picture without checking sources.

Despite this, social media is a quick and effective way to spread scientifically proven, correct health information. That’s why I think medics and other healthcare professionals have an important role on social media to provide accurate medical information and to debunk myths and fake medical news. (more…)

Governments need scientists to shape a brighter, evidence-based future

Our second is Dr Julia Makinde, an HIV researcher at the IAVI Human Immunology Lab, who makes the case for translating science into policy.


A dearth of advisers

A section of the nativity story portrays Herod the Great as something of a tyrant. A man who sanctioned an order to wipe out every male infant born in and around Bethlehem in a pre-emptive action to eliminate the threat of a new-born king. As difficult as it is to imagine anyone, let alone a political leader, endorsing the massacre of innocent children, the story presents an interesting metaphor of complex political motivations and the outcome of a breakdown in the process of policy making.

With vaccinations, climate change and access to healthcare taking centre stage in the global debate, the intersection between science and policy has never been more relevant. Whilst I started out in research with the desire to help create solutions to global healthcare challenges, I have come to understand that the actions taken to disseminate research outcomes are just as important as the process of discovery itself.

Radiation and human health – separating scientific facts from urban myths

Professor Gerry Thomas
This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

Our first is Professor Gerry Thomas, a leading authority on the health impacts of radiation, who tells us why we should focus on the facts.


I was born in the 1960s and grew up believing that the word ‘radiation’ meant something that was infinitely dangerous. Back then, we were led to believe that nuclear weapons would lead to the extinction of our species, and that to be bitten by a radioactive spider would confer supernatural powers! I was therefore sceptical about the use of nuclear power. It wasn’t until 1992, when I started to study the health effects of the accident at the Chernobyl nuclear power station in 1986, that I began to question whether my understanding of the health effects of radiation came more from science fiction than scientific fact.

My mental health and academia: an open letter

mental health academia

As part of UK Disability History Month, Dr Catherine Kibirige reflects on her mental health journey and how she’s using her experiences to help others.


My name is Dr Catherine Kibirige and I’m a Research Associate at Imperial, based at the Chelsea and Westminster Hospital.  

I have a mental health disability. It’s been a difficult journey accepting this, and this is the first time I’ve publicly disclosed it. For a long time, I didn’t want to believe that I had a “mental illness”, or that I was disabled. The funny thing is, once I accepted these things, it’s allowed me to do better and to feel more capable than I have done before. Here in the UK, we’re currently celebrating Disability History Month. In celebration of this, I wanted to share my story and how the College has helped and supported me.     (more…)

Using co-production to improve the way we talk about diabetes

Our medical students are using principles of co-production to improve their understanding of living with diabetes – those with a personal experience of diabetes are encouraged to take part. 


The practice and expectations of modern medicine have changed enormously over the past 20 years. The internet, social media and smartphones have transformed how we access knowledge and data and how we think about healthcare. Tomorrow’s doctors need to be equipped with the values and behaviours to serve our increasingly diverse population, recognise and respond to our global obligations and to flourish in a 24/7 culture where the pace of change can seem relentless.

The reimagined Imperial College School of Medicine’s undergraduate medical curriculum launched in September – this marked the first major curriculum review in the 20 years since today’s School was formed. As the leads of the Professional Values and Behaviours (PVB) domain, we were given the exciting opportunity to work with colleagues across the medical disciplines to rethink how and what we taught.

We wanted to design teaching that will help medical students harness their creativity to find solutions to complex problems and to nurture their resilience and adaptability. We also needed it to develop their ethical reasoning, sense of professional and moral identity, and for them to value team working and collaboration. We have aimed to create authentic, experiential learning opportunities that will support deeper learning and encourage students to see the relevance to their future practice. (more…)

Working with HIV/AIDS patients was the highlight of my clinical career


Originally published on the Imperial College Healthcare NHS Trust blog, Professor Jonathan Weber, Dean of our Faculty of Medicine, shares the story of his career working with people affected by HIV/AIDS.


In April 1982, I was a young doctor with an interest in infectious diseases when my mentor, Professor Philip Marsden, mentioned a new disease he’d seen in New York, which was affecting young gay men and had all the hallmarks of a sexually transmitted infection. He suggested it would be interesting to look for this new disease in London and he thought St Mary’s Hospital might be a good starting point. So in August 1982, I joined Dr Willie Harris’ Praed St Clinic, looking at the immune system of gay men who visited the clinic, guided by immunologist Professor Tony Pinching and virologist Professor Don Jeffries.

Early observations

I was fortunate to be able to work on my research full-time from early 1983, thanks to a fellowship  from the Wellcome Trust; I had gathered a cohort of 400 gay men at the clinic and examined their immune systems. What my colleagues and I discovered was that all the men in the cohort had abnormal immune systems; they all had a low number of CD4+ T-lymphocytes and low CD4:CD8 T-cell ratios. They also had enlarged lymph nodes in their necks, armpits and groin, which is usually a sign that the body is trying to fight an infection. These observations led us to believe that all the patients in this cohort had an early manifestation of AIDS; it was a chilling insight into the scale of the unfolding AIDS epidemic. (more…)
