Despite the myths and fear which surround leprosy it can be treated and prevented with a short course of antibiotics. The disease is spread by a bacteria which is easily killed with these drugs. Although this stops the virus spreading it doesn’t help those who have been disfigured by the parasite, they are still viewed negatively even though they are no longer infectious. As Seydina Alioune Djigo reports, Senegal has embarked on a campaign to both treat Leprosy with drugs and educate more widely on the condition. They have also removed restrictions on those banished to former leper colonies. Also if you died would you donate your eyes to help some else see?

Every year, around 15 million babies in the world are born too early. In countries such as Malawi, Pakistan and Indonesia, more than 15% of babies are premature. Not all survive and some of those that do have disabilities, which might have been preventable with simple care. The question is how to predict which pregnant women might go into labour too early. Reporter Madeleine Finlay investigates a new test using the vaginal microbiome to predict which mums might be most at risk. The first 1000 days. Claudia talks to Professor Monica Lakhanpaul about the critical first 1000 days of a baby's life and a new exhibition that hopes to highlight this key period in a child’s development. Claudia also talks to her about the idea of Reverse Innovation: lessons that richer countries can learn from poorer countries when it comes to health. We’re much more used to it being the other way round, but there are now many projects that are using techniques and ideas learnt from middle and lower income countries in providing health support to communities in the UK and other higher income countries.Presenter: Claudia Hammond Producer: Alexandra Feachem(Picture: A young boy who has just been vaccinated.

Claudia talks to her guest Dr Ann Robinson about a new study from the University of Glasgow in the UK that suggests the virus that causes the common cold can effectively boot the Covid virus out of the body's cells. Some viruses are known to compete in order to be the one that causes an infection and researchers have discovered that it appears cold-causing rhinovirus trumps coronavirus. The benefits might be short-lived but rhinovirus is so widespread it could still help to suppress Covid. Mental Health in Covid frontline health and social care workers.
