On Start the Week Tom Sutcliffe looks at what happens during a health epidemic and its aftermath.

The US activist Peter Staley was instrumental in forcing scientists and pharmaceutical companies to develop life-saving HIV/AIDs drugs. Thirty years later and with drugs now readily available, the concern is that the rate of new cases of HIV remains constant.

Professor Anne Johnson was involved in the biggest-ever-official investigation of Britain's sexual habits, which was vetoed at the time by Margaret Thatcher. She says continuing to understand people's attitudes and behaviour is vital to the nation's health.

More than eleven thousand people died during the Ebola outbreak in West Africa. When the crisis hit its peak in 2014 there were no effective drugs and Professor Peter Horby was one of a team of scientists who conducted a drugs trial in the midst of the epidemic. He explains how what they discovered can be used for future health scares.

The author Louise Welsh is completing a trilogy of novels in which a killer disease has devastated the world. She explains why plague literature has proved so popular and enduring.

On Start the Week Andrew Marr looks back to the end of Empire when government officials systematically destroyed the records of imperial rule, and he explores the impact of outside organisations on a nation's ability to govern. The journalist Ian Cobain has uncovered details of the mass bonfires of sensitive official papers across Africa, which subverted the legal obligation to preserve important historical records. Edna Adan Ismail first came to Britain in the 1950s to train as a nurse before championing women's rights and health at the WHO and in her native Somaliland. She explains how the self-declared independent state of Somaliland, once a British protectorate, has been fighting for international recognition for the last 15 years. Baroness Amos has worked in international affairs both for the government and the UN. Now as the head of SOAS University she says it's vital to think about the world differently, from the perspective of the countries themselves. Keith Somerville has investigated the illegal ivory trade in Africa and argues that regulation - not prohibition - is the best way to stop uncontrolled poaching and smuggling.

On Start the Week Amol Rajan considers the making of the British landscape and an island mentality. The President of the Royal Geographical Society Nicholas Crane looks back over the last 12 millennia to understand how we have shaped our habitat but also how the landscape has shaped our lives. Madeleine Bunting travels through the Hebrides to see what the furthest reaches of these isles can tell us about the country as a whole. David Olusoga re-tells the story of the relationship between Britain and the people of Africa, which reaches back to the Romans, to demonstrate how black history has shaped our world, and the poet Imtiaz Dharker reflects on displacement and belonging.

On Start the Week Andrew Marr hears stories of virtue and vice. Lucy Bailey is directing Milton's Comus, a masque in honour of chastity, in which a Lady, lost in the woods, is tempted by pleasure. In Berg's opera Lulu the eponymous heroine appears to be the epitome of seductive pleasure, an amoral seductress, but William Kentridge's production questions how much she is the real victim. The academic Simon Goldhill charts the transition from the high Victorian period into modernity through one family's relationship with sex, psychoanalysis and religion, while the very modern preoccupation with therapy is laid bare, as Susie Orbach reveals what happens behind the therapist's door.

On Start the Week Andrew Marr talks to the writer Alan Bennett about his life and work. As he publishes his third and, he says, final selection of his diaries, Keeping On Keeping On, Bennett reflects on his reputation for tweeness, his radical politics and sexuality. He writes, "Nothing is ever quite so bad that one can't write it down or so shameful either, though this took me a long time to learn with my earliest diaries reticent and even prudish."

On Start the Week Andrew Marr looks at winners and losers - from microbes and genes, to athletes and adventurers. Ed Yong seeks to expand our understanding of microscopic microbes which inhabit every corner of the earth, and influence our bodies more than we know. Each person's DNA is unique but Adam Rutherford reveals how collectively it tells the story of the history of our species - the successes and the failures. When one's own genetic make-up and hard work aren't enough, there's always chemical enhancement - Jonathan Maitland looks at doping in sport for his latest play, Deny, Deny, Deny. The polar scientist Felicity Aston was the world's first woman to ski alone across the Antarctic and knows what it's like to push your body to the limits. She's now off to Canada's frozen North in search of gold.

On Start the Week Tom Sutcliffe talks to the former Chief of the General Staff Richard Dannatt about the history of the British Army, its role in present conflicts and relations with NATO. The writer Ben Macintyre reveals the wartime antics of one of the most secret regiments, the SAS and the historian Catherine Merridale recreates Lenin's journey across Europe in the midst of the Great War. John Lough was NATO's first representative based in Moscow and explores the tensions on Russia's borders.

In a special edition of Start the Week Andrew Marr is at the Bluecoat Gallery in Liverpool. He's joined by the writer Phil Redmond, historian John Belchem and journalists Gary Younge and Kajsa Norman to discuss historical myth-making, segregation and assimilation - from Liverpool's radical past, to the US and its obsession with guns and race, to the Transvaal and the survival tactics of the Afrikaner community. With the Labour party conference in full swing in Liverpool Andrew Marr will also be discussing how far people will go to retain their cultural identity and what happens when splits appear.

On Start the Week Andrew Marr talks to the MP Margaret Hodge who challenged multinational companies to explain their tax affairs and shone a light on the billions wasted by government every year. The former Chair of the Public Accounts Committee argues that it's time Ministers and Civil Servants learnt from their mistakes. Sir John Armitt masterminded the successful delivery of the 2012 London Olympics and explains why big projects are notorious for budget overspends. MPs will have to decide soon on a multi-billion pound proposal to renovate the Palace of Westminster which would involve them moving out for several years: the political journalist Philip Webster reflects on working in the House of Commons for four decades and how the building influences the business of politics. The best-selling novels of Robert Harris reveal the machinations behind the closed doors of those in power, or seeking it - from Ancient Rome to New Labour. His latest book centres on the intrigue in the corridors of the world's smallest state, the Vatican, as they vote for the next Pope.

On Start the Week Andrew discusses love, loss and scandal. Carrie Cracknell is directing Rattigan's The Deep Blue Sea, the story of an overpowering, self-destructive love affair set in post-war Britain. Michel Faber's collection of poetry explores the loss and grief at the death of his beloved wife, Eva. AE Housman wrote a series of poems at the end of the 19th century - A Shropshire Lad - which were hugely popular and came to encapsulate the nostalgia for an unspoilt pastoral idyll, but the writer Peter Parker says they're also shot through with unfulfilled longing for a young man. Homosexuality only became legal in the late 1960s and John Preston retells the story of the MP Jeremy Thorpe - a tale of sex, lies, murder and scandal at the heart of the establishment.
