More than 100 people are suspected to have died in Zimbabwe in the most recent outbreak of cholera there. Almost 5,000 possible cases have been reported across the country, with the Zimbabwean government moving to ban large gatherings to prevent the spread of the water-borne disease.

Claudia Hammond is joined by Â鶹Éç health reporter Philippa Roxby to discuss how authorities are hoping to avoid a repeat of the last major cholera epidemic in the country, which killed more than 4,000 people in 2008.

We also hear about the Cardiff Model for Violence Prevention, which started out as a PhD project and is now used across the world to help authorities discover where violence is taking place and how it can be prevented. Claudia speaks to the man behind the idea, and the doctor now hoping to introduce it to cities across the US.

Claudia and Philippa also look at new calls for urgent action to address male fertility around the world.

And we travel to Sierra Leone to hear about what has been described as a ‘diabetes time bomb’ in the country.
