A bacterial and/or fungal infection of the foot that is found in sub-tropical or tropical areas such as central and south America, India, Africa, and south east Asia. Madura foot often affects males aged 20 to 40, usually as a direct result of outdoor labour.
The infection enters the foot via any broken skin. An abscess or nodule forms, and grows into a mass of diseased tissue with sinuses (unusual channels) that discharge pus-filled or bloody fluids. The fluid normally contains little granules, those of which are fragments of infectious organisms. The infection can progress to involve the foot bones.
Treatment requires removal of the contaminated tissues (or if vital, amputation) alongside the use of antifungal an antibiotic drugs to kill the infection.
