How WWII POWs held in East Asia helped tropical disease research

Many prisoners of war held captive in Eastern Asia suffered with tropical diseases which their bodies had never been exposed to before.

Some former soldiers are still suffering with the effects, almost 70 years after the Allied victory over Japan.

Doctors at Liverpool's School of Tropical Medicine made use of these soldiers' misfortune to help advance research in the area.
