I have become hooked on playing online chess during this lockdown and after watching the Queen’s Gambit. So we’ll find out if it is actually doing my brain any good and whether it and similar games can ward off dementia.

Margaret McCartney takes us on a fascinating tour through the history of deliberately infecting people with diseases, as the first “challenge trials” with coronavirus are about to start.

Listeners David and Barbara tell us about a treatable condition called normal pressure hydrocephalus that is often mistaken for dementia.

What has the pandemic done to our sex lives? We’ll hear if there’s been a baby boom with Dr Margaret McCartney and Dr Rebecca Thomson-Glover has the lowdown on sexually transmitted infections. We’ll also explore changes to contraception and sexual health services. Meanwhile it feels like we’re on the march to normality, but what about the backlog of patients whose treatment has been cancelled. We speak to Charmayne whose surgery has been held up by the pandemic and Nick Arresti from the British Orthopaedic Association to see how such waiting lists can be tackled.

Most people recover rapidly after catching coronavirus. But I chat to three people who were infected almost a year ago and are still feeling the impact, both on their bodies and their minds.

Doctors are having to rapidly grapple with how to treat patients with long Covid. We speak to one of them, Dr Manoj Sivan, the Research Lead for the Long Covid Service in Leeds, who warns that long Covid could be a “second pandemic”.

We also have GP Dr Navjoyt Ladher answering your questions on the Covid vaccines.

A fever, cough or loss of smell and taste are criteria for a Covid-19 test, but what if you have different symptoms? James Gallagher discusses whether more symptoms should be added to the UK government's list with resident GP, Margaret McCartney and Dr Thomas Struyf of KU Leuven.

Cardiologist Dr Rohin Francis explains what symptoms he sees when patients with coronavirus arrive in hospital.

One of the most common symptoms of Covid-19 is the loss of the sense of smell. It returns after a few weeks in most people but a significant minority still can’t smell anything many months later. James Gallagher talks to Prof Carl Philpott of Norwich Medical School who has led an international panel of nose doctors, assessing the evidence for the best therapies to restore the olfactory sense to people who have lost it following respiratory infections. So-called smell training comes out top as the most evidence-based approach. Carl explains how it works and we hear from two people who are trying to regain their sense of smell.

And Dr Carly Welch from the British Geriatric Society says that delirium has emerged as another symptom of Covid-19, particularly in the elderly.

One or our listeners, Katharine, asks whether mouthwash can help stop the spread of coronavirus. We hunt down the answer with the help of biochemist Valerie O’Donnell, from the University of Cardiff, and our own Dr Margaret McCartney.

Then it’s our turn in the dentist’s chair. Dentistry is up close and personal with a fair amount of splatter, the perfect place for coronavirus to spread. So dentist Paul Woodhouse and University of Newcastle dentist and researcher, Richard Holliday, are on to explain how to make it safe.

It’s an exercise special on Inside Health. This week Amanda wants to know how quickly she can get back to exercising after Covid. Dr David Salman has drawn up some advice and Dr Navjoyt Ladher explains why this virus means we should be taking it easy, as well as having a shocking confession of her own. We check in on George, Jen and Dr Helen Hawley-Hague to see how they are getting on with their physiotherapy in the height of lockdown. And we explore with Sport England’s Tim Hollingsworth what the pandemic can teach us about improving exercise levels. Oh and I think I nearly broke our resident GP Margaret McCartney talking about 'adaptogens'.

In Covid, oxygen levels in the body can crash without noticeable symptoms - it’s known as “silent hypoxia”. This week we’ll be discussing whether letting people monitor their oxygen levels at home with a pulse oximeter could save lives. James talks to Chris Harris, who’s been using one, and two pioneers of the project - Dr Matt Inada-Kim, Consultant in Acute Medicine at Hampshire Hospitals NHS Trust, and Dr Caroline O'Keeffe who runs oximetry@home in North Hampshire.

And the hotly debated topic of rapid, or lateral flow, testing. Local councils are rolling them out for people who can't work from home, and the hope is that they could help us keep on top of the virus by picking out people with Covid. Could it be a way out of the pandemic or could it cause more harm than good? Prof Irene Petersen and our own Dr Margaret McCartney are on the case.

Dr Navjoyt Ladher answers some of the most common questions about vaccines.

Should you take vitamin D pills to ward off coronavirus? Our own Dr Margaret McCartney has been sifting through the evidence in search of answers.

2020 was awful. So what about 2021?

I chat with Prof Neil Ferguson to see how this year could play out and when life might return to normal. Cardiologist Dr Rohin Francis and cancer nurse Aly Foyle are both back to share their experiences of coping during Covid.

I promise you, it’s not all bad news.

And our own Dr Margaret McCartney, alongside Cancer Research UK’s Jodie Moffat, scrutinises a new blood test that promises to find cancer early.

It's a good programme, James.
