Dracunculosis, also known as Guinea worm disease, is a parasitic infection caused by the roundworm Dracunculus medinensis. This disease primarily affects impoverished communities in rural areas of Africa, Asia, and the Middle East.
The life cycle of the Guinea worm begins when a person consumes water contaminated with copepods, tiny water fleas that carry the larvae of the worm. Once inside the human body, the larvae mature and mate, with the male worm dying shortly after. The female worm can grow up to 1 meter in length and migrates through the body, causing intense pain and inflammation.
After about a year, a blister forms on the skin, usually on the lower limbs, and the female worm emerges from it, causing a burning sensation. It is crucial to carefully extract the worm by winding it around a stick or similar object, a process that can take several weeks. This slow extraction is necessary to prevent the worm from breaking and causing secondary infections.
Prevention and control efforts focus on providing clean drinking water sources, educating communities about the importance of filtering water, and promoting behavioral changes to avoid contamination. The World Health Organization (WHO) has been working towards the eradication of dracunculosis, and significant progress has been made in reducing the number of cases worldwide.
