Long Covid – the latest
Health-threatening fungal infections are on the rise and the World Health Organisation identifies the pathogens which pose the greatest risk to human health. Dr Graham Easton, family doctor and Professor of Medical Education at Queen Mary, University of London, tells Claudia how growing resistance to anti-fungal medication resistance, just like antibiotic resistance, is making the problem even worse. Graham also highlights growing health concerns about the recreational use of the drug Nitrous Oxide or laughing gas around the world.One hundred and fifty million people are thought to have Long Covid, debilitating symptoms which persist long after Covid-19 infection, yet the condition is still little understood. To spell out what we do, and don’t, know about Long Covid, a patient and a professor have got together to write The Long Covid Handbook. Patient advocate and film maker Gez Medinger and Professor of Immunology at Imperial College, London, Danny Altman, describe the gaps in medical knowledge and the impact on sufferers of the slow progress on diagnostics and treatment.A recent survey in Chile revealed mental health to be the top health concern in the country. Jane Chambers reports on a Santiago charity called the Itaca Foundation, finding great success by pairing up vulnerable younger people with older people for mutual support. Presenter: Claudia Hammond

Women and children’s health hit by disasters and Covid
After decades of progress – how can we stop the pandemic, climate change and conflict around the world from turning back the clock when it comes to women and children’s health? We hear from UNICEF’s Dr Jennifer Requejo about a new report which examines the impact of natural disasters, war and the pandemic and offers some ideas of how to catch up on targets for improvements. The BBC’s medical and science correspondent James Gallagher thinks he hasn’t had Covid-19 – and takes a blood test to see whether there are any tell-tale signs that he might have been infected unknowingly. And there’s news of how Covid affected life expectancy and whether spending time in the countryside or by the beach might make a difference to how long we live. And a study which suggests that 5 hours is the minimum number of hours sleep we need to stay healthy. Presenter: Claudia Hammond

Can a new star system help us to eat healthily?
If you’re trying to work out what’s healthy to eat and what to avoid – there’s a new five star rating system. Researchers in the US have looked at previous studies which examined how much certain foods increased the risk of developing a particular disease – or if they could even protect you. Dr Chris Murray from the Institute for Health Metrics and Evaluation in Washington says he hopes the star ratings will help people to make informed decisions about their health. We hear from Dr Tammy Tong, a nutritional epidemiologist at Oxford University about the strengths and limitations of this approach. Millions of people around the world use open-pit toilets – a hole in the ground where they can see and smell other people’s waste. The walls are often made of bits of metal and cloth and they are often shared between many families, provoking feelings of shame and disgust. Dr Ian Ross from the London School of Hygiene and Tropical Medicine has been measuring the difference a nicer toilet can have on people’s quality of life in Mozambique – with help from Zaida Adriano Cumbe who talked to families involved in the study in Maputo.Presenter: Claudia Hammond

'Historic' claims for new Alzheimer’s drug
There’s encouraging news about a potential treatment for Alzheimer’s Disease following years of disappointing drug trials. The drug lecanemab is a monoclonal antibody which is designed to remove clumps of amyloid proteins which damage the brain. Professor Bart de Strooper who’s director of the UK Dementia Research Institute explains how patients who had regular infusions of the drug had their rate of cognitive decline reduced by 27% when compared to those given a placebo. Sewage testing has been used around the world during the Covid pandemic – and at the moment children in London are being vaccinated against polio after the virus was found in waste water. The BBC’s Health and Science Correspondent James Gallagher takes us on a tour of a sewer in southern England. Claudia Hammond’s guest this week Professor Graham Easton from Queen Mary University of London looks at whether folic acid could reduce suicide and self harm – and whether it’s ok to take anti-depressants during pregnancy.

Floods spreading disease in Pakistan
Waterborne diseases are on the rise in Sindh province in Pakistan where water levels are still high after record floods. BBC Urdu’s Riaz Sohail visited the region and tells us about the conditions in roadside camps and a hospital in Dadu district.A recently published Motor Neuron Disease trial suggests that a new drug could make a fundamental difference for some people living with the disease. And how does healthcare work if a doctor can only be reached by boat, helicopter or plane? BBC’s Marnie Chesterton went to Greenland and spoke to a healthcare worker in the small village of Narsarsuaq.Presenter: Claudia Hammond

Egypt’s hepatitis C success story
Egypt has almost eliminated the 'silent killer' hepatitis C – less than a decade after having the highest number of cases of the virus in the world. A new report from the World Economic Forum details how they managed to screen almost the whole adult population and treated those infected with the virus which can cause liver damage and even cancer. Professor Imam Waked from the National Liver Institute explains how other countries like Rwanda and Georgia are now following suit – but not quite at the rapid pace which Egypt managed. There is currently a rise in cases of cholera in Syria, and outbreaks of malaria and dengue fever in Pakistan, but for opposite reasons. The first is caused by a drought, and the latter by a flood. And what psychology can tell us about the behaviour of crowds when there’s a false alarm but people feel genuine fear. And James Gallagher reveals what nightmares and learning a musical instrument tell us about our brains.Presenter: Claudia Hammond

Malaria vaccine effective
The trial of a malaria vaccine in Burkina Faso has revealed promising results, protecting young children from being infected by the parasite for a second season. Most malaria deaths are in children under five in sub-Saharan Africa. We hear from one of the research team Professor Katie Ewer, about how difficult it is to create a malaria vaccine. It’s hoped that the world’s largest vaccine manufacturer in Pune, India, will make enough of the vaccine to make it available to every child who needs it in the next few years. A new study has shown that forehead thermometers are not as accurate at picking up high temperatures in black patients as they are in people with white skin. Family doctor Ann Robinson explains how worrying symptoms could be missed in some patients, leading to health inequalities if we rely on devices which are only tested on white skin. And how walking can help to reduce our risk of dementia – and also help tired parents get their crying babies off to sleep. Presenter: Claudia Hammond

Statins rarely cause muscle pain
Statins save lives by lowering the level of 'bad' cholesterol in our blood, reducing the risk of heart attacks and strokes. But warnings about potential aches and pains in our muscles has put off some people from taking them. UK scientists have analysed the best statin trials and found that these side effects are actually rare – and the benefits outweigh the risks. We hear from Professor Colin Baigent in Oxford about how this study should reassure those who need to take them. On Health Check we like to bring you the best possible evidence – and for that we rely on research which has been peer reviewed. Professor Matt Fox from Boston University explains how scrutinising the research of his peers takes time and is unpaid – a situation which he believes is unsustainable. The bleeding disorder haemophilia B means the blood doesn’t clot properly, so a cut or even a bruise can have serious consequences. Elliott who lives in the UK is one of the first people to try a new gene therapy which has effectively cured his haemophilia. And we hear news of a study which claims that tea drinkers might live longer. Presenter: Claudia Hammond
