What is Guinea worm disease
Guinea worm disease (also known as dracunculiasis) is on the verge of eradication with only 28 cases reported in 2018. There are now only 4 countries in Africa that are endemic for Guinea worm disease.
The parasitic illness is caught by drinking water that contains water fleas infected with Guinea worm larvae. Once in the body, the larvae reproduce. Over 10 to 14 months in the body, female larvae can grow into worms over a meter long. These worms then begin to emerge from the skin through very painful blisters on the legs or feet. This is also accompanied by fever, nausea and vomiting.
Once a worm has emerged from the body, it must be carefully and slowly removed over several weeks. The wound caused often develops a secondary infection which increases the time it takes for an individual to resume normal activities.
If the worm is not removed, it can lead to septicaemia (infection across the whole body) and permanent disability for the person with Guinea worm disease.
