Welcome to hell - a district hospital in Malawi, where tens of thousands of people come each year suffering from the world's deadliest diseases, and only one doctor is there to help them all - Robert Lapham Ayella. He's a local hero but in Malawi, the heroes are tired.

For the last 20 years, Africa's doctors have been leaving the continent for a better life overseas. As Dateline's Aaron Lewis reports, Malawi has just two doctors for every 100,000 people. At the same time, tuberculosis has resurged, combining with HIV in a deadly new epidemic. Lewis visits Malawi to look at the crisis on the ground, then travels to Europe to track down Malawi's expatriate doctors to ask what must be done to get them to come home.

About International Dateline 

SBS Dateline, which began in 1984, is Australia's longest-running international current affairs program. It has a well-earned reputation for authoritative and incisive reporting. Dateline has taken the traditional way of producing TV current affairs and turned it on its head. Reporters who used to travel with a cameraperson and sound recordist now travel alone and have the responsibility of both filming and reporting their stories. The reporters became video-journalists, gaining access to people and places that the conventional camera crews cannot.
