Graphic 7 - Transmission of guinea worm disease
Transmission of guinea worm disease
(In this graphic, one man relieves the pain of his guinea worm blister and allows larvae to contaminate the water, while another man drinks directly from the same pond.)
• When guinea worm comes into contact with water, it will emit its larvae.
• When people with guinea worm enter the pond to collect water or bathe or wash their clothes or simply relieve the pain of their sores, they recontaminate that source with guinea worm larvae.
• Anyone who drinks from a water source contaminated with guinea worm is at risk for the disease.
• No one should drink water directly from a suspect source without filtering it first.
