• Many of the discussions around how we use the internet focus on its potentially negative impact on our wellbeing, but is that actually the case? A new study of more than 2 million people says being online may actually improve things such as our life satisfaction and sense of purpose.

    Claudia Hammond is joined by Professor Matt Fox from the Departments of Epidemiology and Global Health at Boston University to look at what this might tell us about the effects of being able to access the internet.

    We also speak to Dr Edgard Camarós from the University of Santiago de Compostela in Spain, to hear about his study looking at ancient Egyptian skulls that’s found signs doctors at the time may have performed cancer surgery.

    Claudia and Matt also discuss the latest on a combined vaccine for flu and Covid, as a single shot jab passes an important part of final-stage scientific checks.

    And we hear about the ‘bug bounty’ programme paying researchers to find errors in published scientific papers.

  • A third human case of bird flu has been reported in the US in a farmworker in Michigan who experienced respiratory symptoms. It follows a recent rapid spread of the virus among dairy cows across the country.

    Claudia Hammond is joined by public health consultant Dr Ike Anya to discuss the latest developments, as half of the nation’s stockpile of the H5N1 vaccine is made ready to deploy.

    We also hear from the women who’ve posted on social media that they’ve become pregnant after using GLP-1 drugs like Ozempic for weight loss. Claudia speaks to Dr Charlotte Moffat from the University of Ulster about whether the drugs could be interfering with birth control and boosting fertility.

    We also hear from author David Robson about his new book ‘The Laws of Connection’, which explores the science and health effects of our social connections, and discuss what social strategies we can all take to improve how we socialise.

    And Claudia and Ike take a look at a competition in South Korea trying to raise awareness of stress where the person with the lowest resting heart rate wins.

  • Life expectancy is expected to increase by almost five years around the world by 2050, according to new research. The Global Burden of Disease Study says countries with lower life expectancy are expected to see the biggest increases.

    Claudia Hammond is joined by BBC Africa health correspondent Dorcas Wangira to hear how public health measures are behind the predicted increases.

    We also hear about how negotiations at this week’s World Health Assembly to secure a global deal for countries to prepare for pandemics have fallen through.

    Claudia and Dorcas discuss new research in Kenya into the time of day mosquitoes are biting children in school, and what it tells us about whether the insects are getting smarter.

    We also hear about the project twinning hospitals in Mexico and the US to try to improve the survival chances of children with leukaemia.

    And new research from Australia suggests having a baby takes much more metabolic energy than previously thought.

    Presenter: Claudia HammondProducer: Dan WelshEditor: Holly Squire

  • This week, we’re looking at examples of innovative thinking in medicine. A new, non-invasive device could help people with paralysis to regain movement. And as Namibia passes a critical milestone, we look back on one of the biggest developments in preventing mother-to-child transmission of HIV.

    Also on the programme, an update on the Korean doctors’ strike, and a summit looks to tackle the often-overlooked problem of indoor air pollution.

    Presenter: Claudia HammondProducer: Margaret Sessa-HawkinsEditor: Holly Squire

  • We look at the reasons behind a recent surge in Whooping cough cases in Europe and Asia. Also on the program: why are women more susceptible to heat-related mortality, the small patches that could revolutionise vaccines, and the recent Northern Lights sightings have us looking at the psychology of awe.

    Presenter: Claudia HammondPanellist: Smitha MundasadProducer: Margaret Sessa-Hawkins

  • A research center in Sudan had brought hope for neglected disease mycetoma, we hear from a mycetoma expert how the conflict has affected research. Also on the show, have researchers discovered a genetic form of Alzheimer’s, and for the first time an orangutan is seen making a medicine to treat its own wound – what can this tell us about the history of human medication?

    Presenter: Claudia Hammond Producer: Margaret Sessa-Hawkins

  • There's been a lot of coverage in the media around the world about the mental health difficulties facing boys, but looking at figures for mental health problems in children and teens, there's clearly something going on with girls too. For some years, research has shown more girls are experiencing problems than boys, with a troubling spike in difficulties showing up in the late teens.

    On today's programme, Claudia Hammond explores the issue with a variety of guests. She visits King's College London's (KCL) Institute of Psychiatry, Psychology and Neuroscience to speak to Gemma Knowles, a lecturer in epidemiology and youth mental health; Craig Morgan, professor of social epidemiology and co-director of ESRC Centre for Society and Mental Health; and Valeria Mondelli, a clinical professor of psychoneuroimmunology - about their work with young people, trying to uncover the deeper causes and to find new solutions.

    She also hears from some of the young people involved in a major study into mental health, conducted by the team at KCL and spanning nearly a decade.

    Claudia is joined by Dr Linda Blair, a clinical psychologist, who uses her own professional experiences to discuss the trends and challenges of youth mental health.

  • After a number of incidents around the world so far this year that have left dozens of flyers needing hospital treatment, we look at how a rise in air turbulence because of global warming is leading to more and more injuries to passengers.

    Professor Paul Williams from the University of Reading in the UK tells us why turbulence is so hard to plan for, how new technology might be able to help solve the problem, and how despite an increase in incidents it’s still incredibly rare to experience extreme turbulence./

    Claudia Hammond is also joined by Monica Lakhanpaul, Professor of Integrated Community Child Health at University College London, to look at how a shortage of HPV vaccines is leading to millions of girls across Africa missing out on receiving the shots.

    Monica also tells us about her new research on the barriers children with epilepsy are facing being able to exercise.

    We also explore what it’s like for people that don’t have an inner monologue and can’t imagine sounds – a phenomenon known as anauralia.

    Presenter: Claudia HammondProducer: Dan Welsh

  • After a 50% jump in meningitis cases reported across Africa last year, Nigeria is becoming the first country to roll out a new 5-in-1 meningitis vaccine. The Men5CV vaccine protects people against five strains of the meningococcus bacteria.

    Claudia Hammond is joined by New Scientist medical journalist Clare Wilson to discuss how it’s hoped the treatment will help significantly reduce cases of the disease.

    We also head to Brazil to hear how the country is dealing with long Covid, four years after the pandemic.

    Clare also tells Claudia about the new cancer treatment testing different drugs on thousands of miniature tumours to see which of them works best. The team behind the research at Florida International University in Miami say they hope it could eventually be used routinely for everyone with cancer.

    We also get a new update from British journalist Mike Powell, as we follow his journey after receiving a kidney transplant.

    And Claudia and Clare look at how patches of skin grafted onto people receiving lung transplants are being used as a way of spotting organ rejection in a new trial.

  • Claudia Hammond presents a special edition of Health Check from the Northern Ireland Science Festival, where she’s joined by a panel of experts to discuss the psychology of hope.

    With a live audience in Belfast’s Metropolitan Arts Centre, Claudia speaks to Dr Karen Kirby, senior lecturer in psychology at the University of Ulster; Dr Kevin Mitchell, associate professor of genetics and neuroscience at Trinity College Dublin; and author Sinéad Moriarty.

    Topics include the role of hope in medical scenarios, if we can learn to be hopeful, and how we can hold onto hope in the modern world. We also hear questions from our audience, including whether or not we should all just lower our expectations.

    Presenter: Claudia HammondProducer: Dan Welsh

  • As the recent surge in cases of dengue fever continues across Latin America and the Caribbean, Puerto Rico declares a public health emergency.

    Claudia Hammond is joined by Professor of Global Health and Epidemiology at Boston University, Matt Fox, to hear how warmer temperatures have lead to outbreaks of the mosquito-borne disease around the world, with millions of cases reported so far this year.

    We speak to the artist Jason Wilsher-Mills at his latest exhibition inspired by his childhood experiences of disability, and hear the role it played in his journey into the arts.

    Claudia and Matt discuss the spread of mpox in the Democratic Republic of the Congo, with cases reported in all but 3 of the country’s 26 provinces.

    We hear from Uganda about the project hoping to help provide essential equipment for safe anaesthesia in children’s surgery.

    And the study that says just two nights of broken sleep are enough to make us feel years older.

  • The latest on the first procedure to transplant a kidney from a pig into a living patient. Claudia Hammond is joined in the studio by Dr Graham Easton to hear how the organ was genetically modified to reduce the risk of it being rejected following a four hour surgery in Massachusetts in the US.

    We also hear about the data that’s linked working outdoors in sunlight to non-melanoma skin cancer. The report from the World Health Organisation and the International Labour Organization says one in three deaths from this type of skin cancer is caused by ultraviolet radiation from outdoor work.

    Claudia and Graham also discuss new research from India that’s found working in extreme heat can double the risk of stillbirth and miscarriage for pregnant women. It’s also calling for more advice for working pregnant women around the world.

    We go to Cameroon to hear about the medicines being sold to passengers on buses, despite there being no evidence they actually work.

    And we hear how some reporting over claims that intermittent fasting is linked to an increased risk of heart-related death may have jumped the gun.

  • Most people with Covid-19 make a full recovery within 12 weeks, but some patients have experienced ongoing symptoms for much longer. This has become known as ‘long Covid’. However, new research suggests that the rates of ongoing symptoms and functional impairment after Covid are indistinguishable from other post-viral illnesses, and that long Covid may have appeared to be a distinct and severe illness because of high volumes of Covid-19 cases during the pandemic. Presenter Claudia Hammond is joined in the studio by BBC Health reporter Philippa Roxby to discuss the findings. If long Covid is not unique, could this new spotlight encourage research that would help sufferers of other post-viral conditions?

    The use of heart pacemakers have become a standard procedure in many countries. Pacemakers are small electrical devices implanted in the chest that send electrical pulses to the heart to keep it beating regularly and not too slowly. The devices can be lifesaving for some people. But devices can malfunction, there can be problems with leads and the batteries in them don’t last forever. Over half of all pacemaker patients live long enough to require a battery replacement operation, which carries a risk of serious complications including life-threatening infection. This can have big cost implications for health systems and devastating consequences for patients. Reporter Hannah Fisher attends one of these operations to find out more.

    An initiative to make the right to abortion part of the EU Charter of Fundamental Rights has been introduced to the European Parliament. This comes on the heels of France making abortion a constitutional right earlier this month, in stark contrast to the removal of abortion as a constitutional right in the USA in 2022. We assess the initiative’s chances of success and discuss the ripple effect of US politics on abortion rights across the rest of the world.

    Amputees who use prosthetic limbs have to get used to the fact that they do not experience the sensations that they were previously used to. But now researchers in Italy and Switzerland have developed a temperature-sensitive robotic hand that allows amputees to discriminate between objects of different temperatures and sense bodily contact with other humans. Solaiman Shokur of École Polytechnique Fédérale de Lausanne tells Claudia how it works.

    And Philippa brings the story of Paul Alexander, a polio survivor who spent most of his life inside an iron lung. An iron lung is a metal cylinder enclosing the body up to the neck, with bellows to force the lungs to inflate and deflate. The device has been obsolete since the 1960s, but he continued to use his until he died recently. 72 years after Paul contracted polio, we look at how the disease has nearly been eradicated worldwide.

  • The toxic mineral asbestos is still mined across the world, despite it’s much documented links to cancer. Now there are promising results from a new global study into one of the most aggressive types of cancer caused by exposure to asbestos.

    Also on the programme, we receive an exciting update from Mike, who has gotten a long-awaited kidney transplant, and we discuss new treatment protocols for Hepatitis B and how they could better serve people in southern and eastern Africa.

  • More than one billion people in the world are now living with obesity. The number of people who are underweight has also fallen according to a new global study, but this does not necessarily mean that people are better fed. In some countries insufficient food has been replaced by food that does not contain the nutrition that people need, with obesity now the most common form of malnutrition in many places. Claudia Hammond talks to study author Professor Majid Ezzati about the results and what can be done to halt the trend of increasing global obesity.

    Research has shown that sleep deprivation can increase the risk of developing type 2 diabetes, while regularly eating fruit and vegetables can reduce the risk. Yet it wasn’t known whether a healthy diet could compensate for a lack of sleep. Now, researchers at Uppsala University in Sweden have discovered that people who eat healthily but sleep for less than six hours a day are still at higher risk of type 2 diabetes. GP Dr Ayan Panja joins Claudia in the studio to pick over the findings and talk about the importance of sleep to your health.

    Ayan also brings news of a new study into screen time and language development in children. While this study found that screen time has a negative impact on children, previous studies have found that the right kind of television programme can be beneficial. Claudia and Ayan discuss the difficulties of finding answers to questions about the impact of screen time.

    With the Oscars about to take place in Hollywood, we’ll be wondering what the best films are for learning about global health. Professor Madhukar Pai from McGill University in Canada uses movies in his teaching, and has even put together a list of over one hundred films that accurately portray health stories. He tells us what makes the perfect health movie.

    And there’s more from British journalist Mike Powell as he prepares for his kidney transplant operation.

  • More than 1,600 junior doctors have been on strike in South Korea in a dispute about working conditions and Government plans to add more medical school placements. BBC health reporter Smitha Mundasad joins Claudia Hammond to explain the latest.

    Smitha also brings Claudia new research about the first ever prehistoric case of a child with genetic condition Edwards’ syndrome. And some innovative solutions to get blood to so called ‘blood deserts’; large rural areas where there is no access to blood transfusion.

    Claudia and Smitha also hear how one American woman Lynn Cole’s fight with serious blood infection helped scientists understand more about phage therapy. Lynn died in 2022, but Claudia speaks to her daughter Mya.

    Health Check also continues to follow British journalist Mike Powell as he prepares for a kidney transplant operation. This week he is in conversation with Justin Pham in Los Angeles, who also has kidney failure and has been on dialysis since last year.

  • Research shows that large numbers of Covid deaths could have been prevented if people in low and middle income countries had better access to vaccines. But this week the World Trade Organisation said it could not reach a consensus on waiving intellectual property rights on Covid-19 tests and treatments for poorer countries. Claudia Hammond is joined by BBC Africa health correspondent Dorcas Wangira in Nairobi, to discuss the impact of vaccine inequity on her part of the world.

    Dorcas also brings news of a new Ebola study showing that even people vaccinated once they were already infected with Ebola had a substantially lower risk of dying. It suggests that not only does the vaccine help prevent Ebola, it also improves the survival odds of people who have already contracted it.

    Oral Rehydration Salts are a lifesaving and inexpensive treatment for diarrhoeal disease, a leading cause of death for children around the world. It is cheap, effective and has been recommended by the World Health Organization for decades - so why is it under-prescribed? That’s a question that researchers at the University of Southern California set out to answer by sending ‘mystery patients’ to thousands of healthcare providers in India. Prof Neeraj Sood tells Claudia what they discovered.

    And, a new study suggests that if the fourth digit on the hand of a professional footballer is longer than their second digit, they can metabolise oxygen more efficiently. This comes on the back of previous research about how differences in finger length can be a marker of heart attack and severity of Covid-19. Can you really make predictions about someone’s health based on the way their hand looks?

  • Carnival hits the streets in Rio de Janeiro, Brazil this week. As well as preparations for the crowds and colourful processions, health authorities have also been putting in extra measures to try to contain a huge outbreak of dengue fever. Last week a health emergency was declared in the city. And as Claudia hears from Peruvian health journalist Fabiola Torres, cases are rising to levels not seen for decades across the whole of Latin America.

    Consultant in public health Dr Ike Anya is in the Health Check studio to take a deeper look at Dengue. He also brings news from Alaska, USA where an elderly man has become the first person to die from Alaskapox, a viral disease more commonly found in small animals like shrews and voles. And could new UK research on 50,000 people’s blood, help us get one step closer to a predictive blood test for Alzheimer’s disease?

    Claudia and Ike hear from British journalist Mike Powell who has serious kidney failure. Last week Mike’s kidney transplant operation had to be cancelled due to his donor’s health. He’s hoping for some better news this week.

    And Claudia speaks to Dr Ruth Namazzi at Makerere University in Uganda. She is co-author of new research that suggests that a common drug for treating the symptoms of sickle cell anaemia could have a transformative effect amongst children with the blood condition in sub-Saharan Africa.

  • The hospital in Old Fangak, South Sudan is extremely remote; it’s a place that can only be accessed by boat, using the river Nile. The airstrip has been flooded for the past four years – flooding that has also destroyed crops and drowned cattle. Since April 2023, 501 cases of hepatitis E have been treated at the hospital, and 21 people – mainly women – have died. Now, doctors have launched a vaccination campaign that targets women and girls in communities that are up to eight hours by canoe from the nearest healthcare facility. Matt Fox, Professor of Global Health Epidemiology at Boston University, tells Claudia Hammond about the challenge of distributing vaccinations in such a challenging environment.

    Matt also brings news of a study that suggests that up to 10% of patients diagnosed with dementia might actually have cirrhosis of the liver. Cirrhosis can cause cognitive impairment with a very similar presentation to dementia but, crucially, it’s reversible. A study of military veterans in the USA indicates that screening could prevent misdiagnosis.

    36% of all human rabies deaths in the world happen in India - 20,000 deaths every year. 97% of these deaths happen through infected dog bites. India has the largest number of stray dogs in the world and also the largest number of stray dog attacks - around 17 million dog bites annually. Chhavi Sachdev reports from Jaipur on an organisation that believes they’re on their way to making the city rabies free.

    As Chinese new year is celebrated around the world, we look at a foodstuff that is synonymous with the celebrations – eggs. Minchao Jin is a Clinical Associate Professor at NYU Silver School of Social Work in Shanghai, and he tells Claudia about his work assessing whether a hard-boiled egg a day can help the nutrition of schoolchildren in poor, rural parts of China.

    And it’s a frustrating week for journalist Mike Powell as he continues his journey towards a kidney transplant.

    Presenter: Claudia HammondProducer: Ben Motley

  • There are neglected tropical diseases, and then there is Noma, a severe gangrenous disease which tends to affect 2 to 6-year-olds and has a 90% fatality rate. Its quick onset means that often children die before they can get medical attention and it is thought that many medical professionals don’t even get taught about early symptoms. Claudia meets Fidel Strub, originally from Burkina Faso who survived Noma to ask about the impact on his life. This week the first meeting of an international group of researchers working to improve awareness and treatment of the disease is taking place. South African epidemiologist Dr Elise Farley explains why more research is desperately needed.

    Family doctor Dr Ann Robinson brings promising news for treatment of another tropical disease, Nipah virus. The first-in-human vaccine trial has begun in the UK. And new research into the effectiveness of testosterone treatment in men.

    Journalist Mike Powell updates Health Check as he continues his journey to kidney transplant. And a charity in Northern Ireland which is using a virtual reality experience to give seeing family members a better understanding of what it’s like to live with visual impairment.
