Rebecca Blaylock is a student on the Master of Public Health programme at Imperial and here makes the case for increased access to reproductive healthcare.
Students from Imperial’s Master of Public Health programme recently organised a screening of the award-winning film “Vessel”. Vessel chronicles the story of Dr Rebecca Gomperts – a former doctor on a Greenpeace ship – who had an innovative idea to provide women with vital reproductive health services. During her time travelling the world with Greenpeace, Gomperts witnessed the unbearable suffering caused by unsafe abortions. She saw women haemorrhage to death, die from sepsis and sustain life-long disabilities, and refused to “stand there and just let that happen”. Around 25 million unsafe abortions take place every year, accounting for between 4.7 and 13.2% of global maternal deaths.
On World Health Day, Professor Azeem Majeed takes a look at the past, present and future of the NHS.
In 2018, the United Kingdom’s National Health Service (NHS) celebrates its 70th anniversary. With the creation of the NHS in 1948, universal health coverage was finally implemented in the United Kingdom, with the NHS replacing the previous patchy health coverage schemes that had left many people with limited access to health services. All residents of the United Kingdom were given the right to register with a general practitioner, who was responsible for both providing primary care services and organizing referrals for specialist care.

World AIDS Day takes place annually on 1 December as an opportunity for people worldwide to unite in the fight against HIV and to show support for people living with HIV/AIDS.
To mark World AIDS Day 2017, we have published a series of blog posts to highlight the important and varied research that takes places at Imperial. Three experts from Faculty of Medicine share their interest in HIV/AIDS which spans from the elusive vaccine to the economics of the epidemic.
The role of an economist in the HIV epidemic
As an economist, my research on HIV takes a higher-level population view. We advise policy makers in governments and international organisations on the cost-effectiveness of preventive and treatment interventions in the countries most ravaged by HIV. By estimating the benefits and costs of interventions, we can identify the ones that promise greatest improvements in population health.
The largest community-randomised trial of the universal HIV test and treat strategy
For example, we are currently conducting an economic evaluation of HPTN071/PopART; the largest study on the impact of a package of testing and prevention interventions on new infections in Zambia and South Africa. We measure the benefits of treatment to HIV-infected individuals who are found and diagnosed earlier because of PopART, and we expect that the interventions will also prevent new infections. It’s tricky to estimate exactly how many individuals will be spared from getting infected in future, but we work with epidemiologists who use complex modelling to project the number of prevented infections into the future.

It is the time of year again for HIV Testing Week!
Coordinated by HIV Prevention England (HPE) since 2012, National HIV Testing week has focused on three main aims:
improving awareness of HIV testing, particularly among communities at high-risk
increasing opportunities to take the test in clinics and other community settings
reducing the number of people diagnosed with HIV at a late stage
This year’s theme is ‘Give HIV the Finger’ – a cheeky reference to the free finger-prick test that people can receive by post, to provide a blood sample for testing without attending a clinic.
HIV in the United Kingdom
According the latest surveillance from Public Health England (PHE), just over 5,000 people were diagnosed with HIV in 2016; this is an 18% drop compared with 2015.[i] 54% of diagnoses were among gay and bisexual men; 19% and 22% among heterosexual men and women respectively. Late diagnosis is an important predictor of morbidity and premature death in people with HIV. In 2016, 42% diagnoses were made at a late stage of infection when treatment is less effective. (more…)
Imagine you are running a marathon. You have reached the final mile of a long and arduous journey. You turn the last corner expecting to see the finish line, and instead you see a huge vertical ascent. The finish line is waiting at the top, hundreds of metres above you.
Such is the plight of the Global Polio Eradication Initiative. In 1988, the year the initiative was launched, polio paralysed an estimated 350,000 people worldwide – roughly 1,000 each day. Over the last three decades, a globally coordinated vaccination campaign has fought the disease back to a few remaining refuges in Afghanistan, Pakistan, and Nigeria. In 2017, wild poliovirus has caused just 12 cases so far.
As we mark the fifth annual World Polio Day, the finish line of the eradication marathon is firmly in sight, but getting there will be a tough climb.
Why has polio proven so hard to vanquish? First and foremost, the disease’s final strongholds are regions of immense political unrest, and news of deadly attacks against vaccination workers are all too familiar. Every step towards polio’s eradication is one that requires those at the front line to put their lives at risk. (more…)
Today is World Rabies Day. The goal of this global day is enhanced awareness spurring further efforts to prevent rabies, a viral disease that kills tens of thousands of people each year mainly in Asia and Africa. Two years ago, international organisations – including the World Health Organization and the World Organization for Animal Health – agreed to an ambitious, but achievable common goal: to end human deaths due to canine rabies by 2030. In fact, ‘Rabies: Zero by 30’ is the theme of the 2017 World Rabies Day.
Why today? 28 September 2017 is the 122nd anniversary of Louis Pasteur’s death. It was he who developed the first vaccines for both rabies and anthrax. All mammals can become infected with the rabies virus, and rabies is present on every continent except Antarctica. This can sound overwhelming. However, up to 99% of human rabies cases result from human dog bites. So what can be done to keep ‘man’s best friend’ from transmitting this fatal virus? Vaccination! (more…)
Can you imagine life without access to clean water? Unfortunately for 663 million people this is a reality. That’s nearly one in ten people worldwide living without a safe water supply close to home, spending hours queuing or trekking to distant sources and coping with the health impacts of using contaminated water. SIWI’s (Stockholm International Water Institute) World Water Week, is a pertinent time to reflect on important research carried out by the Schistosomiasis Control Initiative (SCI), a non-profit initiative based at Imperial College London, which highlights why access to clean water is so important to human health.
Schistosomiasis, also known as bilharzia, is a type of parasitic ‘worm’ infection affecting individuals in sub-tropical and tropical regions of the world. It is a major, yet neglected public health problem, where estimates showed that at least 218 million people required preventive treatment in 2015, of which at least 20 million suffer from severe and debilitating forms of the disease (World Health Organisation, 2016). The SCI support treatment programmes against schistosomiasis and soil-transmitted helminth infections in 16 sub-Saharan African countries and Yemen. Since its foundation in 2002, the SCI has supported the delivery of over 140 million treatments for these infections.
Close your eyes and imagine the high-pitched shrieking of cicadas unified in a crescendo of noise from the treeline. Fireflies blinking their fluorescence through the undergrowth. Bats swooping silently overhead, rustling your hair with their wing beats. Trekking across steep hillsides of wasabi plants during a rainstorm. Not the average working week of a researcher in the School of Public Health, but just some of the sights and sounds I was fortunate to experience when I visited Taiwan in May as a National Geographic Young Explorer.
The aim of my 10-day visit was to collect and swab as many tadpoles, frogs and salamanders as possible. Why, you ask? Tragically, amphibians are being struck down by a fungal plague. In the past 20 years there have been global biodiversity losses, mass mortality events and the extinction of over 200 frog species attributed to chytridiomycosis—a disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd). To give you an idea of scale, some researchers are referring to this outbreak as the sixth mass extinction event: something on a par with the dinosaur die-off 66 million years ago in terms of species lost. More recently emerged is its sister pathogen Batrachochytrium salamandrivorans (Bsal), which is causing the deaths of European fire salamanders in the Netherlands. It’s estimated that populations have declined by nearly 20% per year since 2008, leading Bsal to be described by some as the ‘perfect pathogen’. (more…)
20 June is World Refugee Day, and my short morning walk to the American University of Beirut (AUB) provides a daily and grim taste of the global refugee crisis. At 8:50am I take a right out of my Beirut flat onto a bustling and polluted Lebanese street. I live opposite a cheap hotel that hosts medical tourists – Iraqis, mainly – due to crippling of health systems in the region. A quick glance to my left and I’ll see two women outside a supermarket holding babies and pleading with ingoing shoppers for a small bottle of milk. To my right I see a large but flattened cardboard box, knowing this will soon become the cushion for a young mother and her two children. I’ll see them on my way home and I’ll worry about the toddler, who looks thin and tends to wander into the road.
By 8:55am I’m on a steep descend towards the main entrance of AUB. As I pass by a beautifully colourful series of flower shops on my left, I see an elderly man in plain clothes sitting on a white, plastic chair and holding a cup of tea. He has an expressionless face, he has damaged red skin around his ankles, he is obese, and he is silent. We exchange a look and I feel despair; not just for him, but for the nine year old girl who used to be in his place up until April this year. Also silent, she would sit and curiously watch passers go by. She was from Aleppo, a city brought down to its knees in recent years, and she told me her mum wouldn’t let her go to school in Lebanon. I dare not ask the elderly man what happened to her, but let’s not be under illusions – gender-based violence and early marriage are a feature of armed conflicts. (more…)
